Hi everyone, I can't thank you enough for the love you are showing this video. I didn't expect it. Feel free to check out the next video of me adding the performance parts to her :) Thank you all. Merry Christmas :)
Road Dawg, the very first Corvette I ever drove was a 2003 50th anniversary. A friend of mine let me borrow it 2 years in a row for Prom. It’s where my love of vettes came from!!
Hi Keith. Thank you very much, I would love to get it re-dyno’d. Maybe this Spring or fall! Thanks for commenting. Had a great Thanksgiving! I hope you did as well! Take care!
Hi Chris, I have been told it needs a new tach filter 🤷♂️. It’s a little wire and box behind the engine. Pretty easy fix apparently! I’ll make a video when I do! Thanks man. Take care!
Yeah, I know what you mean. I recorded videos for my own fun wayyyy before TH-cam. I then figured why not upload it now that I have a channel. Thank for watching and commenting.
Nice video! I have a 91 vette too and was looking for a video like this to see around what number it makes to the wheels! Thanks for the awesome video!
Hi Thomas, you are very welcome. Thanks for watching. I was hoping to do a dyno this year too but not too sure it’s going to happen! Awesome you also have a 91 :) take care!
I just put a L98 Corvette engine in my 87 iroc z with a LT1 cam, Z28 springs and 1.6 self aligning roller tip rocker arms. I changed the Y pipe to a 3 inch outlet and 3 inch mid pipe to the muffler. I also did the air foil with 24 pound injectors as well the stage 2 jet performance chip performance chip. My car is putting down 258 horsepower to the rear wheels at 4300 rpm and 324 foot pounds of torque at 4000 rpm I love my Camaro more then ever. Runs like a bandit.
I would bet money you gained less than 15 HP from the mods going by experience. You need a ram intake along the lines ot the LT1 style to make good numbers. The tuned port is a torque monster not a high HP intake. I always love the look of the tuned Port though. It just looks so cool.
@@Doulop , That's the way I feel too. Living in Pennsylvania, we don't really have the right road topography for massive horse. But the torque is a monster, when you need to pass on those country roads. Be careful though, I had my '90 L98 break traction with new tires on dry pavement and it's an automatic! Best of luck to you.
I have a black 91 c4, waiting to get it back . Had a d1 procharger added to it and the engine built up . The mechanic said it should be around 500hp so I'll see when I get it back
Cool! I can’t find a dyno to check mine. I’m planning on replacing all the bushings on mine this winter. After 50k miles on a 95, you can definitely feel all of them!
Hi Johnny, yeah, dyno’s are hard to find, honestly. There are a few but not a ton. What bushing are you referring to? Thanks for commenting. Take care!
Love the car I have watched a bunch of your videos and learned a lot from them.I had a 1979 L48 back in 1992 it was ok but slow .Do you ever wish you bought a 96 lt1 for more hp ?Im 53 and have had lots of standards but want a automatic and will be buying one in the spring after I sell my s by s Polaris which I never use .I live in Cambridge Ontario Canada So any corvette cost a lot more and are hard to find .I would love to see the numbers after all the cheap mods like: change filter remove part of intake cover air foil and remove screen in mass air in throttle body .
Hi TellMeHD, thanks so much for watching the videos. That means a lot to me. Honestly, when I was 19 (when I bought the car) I knew very little about the C4. I knew a lot about the C6 because it had just came out a few years earlier. I had no idea what I was buying. These days, I would have done a ton of research. To answer your question, I often wish I would have gotten a later year C4 with the LT1. That being said, though, I wouldn’t trade my current car for one. I love that car so much! I am definitely doing another dyno this spring as long as I can figure out why my radiator fans aren’t running. Thanks for commenting. Take care!
Uh,that would be 96 LT4. All had ZF 6 speeds.Factory rated @330hp. Most all of them,including mine,Dyno higher. They didn't want to outshine the new body style 97(C5) which was 345hp. Love the C4 content.
I just drag my 91 C-4 out of the pasture. Five yrs ago had little disagreement with my community speed trap. So no tickets and park it. Finishing C-3 496 NOS full cage car. Plus DVR cameras witness to deal with speed trap.
Impressive!!! I hear you man!!! hahaha Ive had a few corvettes tho none were the awesome HP ones one was a UGLY 74 Brown C3 witht he L48 and factory 4 speed with a bad 2nd gear synchronizer so u had to hold it in hahaha my other vette was a 86 with the l98 auto..... see back in the 80's that was fast for the day..since then I got into F-bodys cars because u cud smoke vettes with their own engines.
I'm an original owner of a '91 coupe with 6 spd and adjustable suspension. have driven it all over and taken it to the limits on the curvy's in the Ozark mountains in MO and AR. Fastest I've ever been was 140mph. It is still bone stock with the original exhaust and even the windshield wiper blades, lol. Would like to have a bit more sound. Are those Borla exhausts you have on this one?
I have a 1990 ZR1 with 38K mile , black on black... Thinking about selling it... A was told a set of headers, a chip, and convert it to a single-stage flywheel should bring the HP to 450-470 . It came stock detuned and could still hit 187 MPH
@@ad356 The '93 was a first-generation, non-vented Optispark. Even still, 40K miles is an early fail for OEM. Once you replace it, you'll be doing it over and over again as Mitsubishi and Delco no longer make them. Factory stopped selling new units years ago. Final prices were around $1,200 for the part. $50 Chinese knockoffs are just as reliable as a $600 MSD unit. I hope you kept your old OEM Optspark. You can harvest the highly coveted Mitsubishi optical sensor and repurpose it. Rebuilders are paying $$$ for the discontinued sensors.
Some folks add aftermarket air box and filters that are lightly oiled and mess up the MAF sensor. And check for the PROPER Factory plugs and wires being used.
Did you sync your TPS and Control valve it just seems a little lagging. Those MPH numbers should go up a litttle faster. I did mine to read I believe 5.4 volts and when they are synced it's crazy how fast it gets.
is your idle ok because you will notice you can turn the screw to adjust it and the computer will just go back to where it was. You need to bypass the computer unplug the idle control valve set your idle speed plug it back in then do your TPS to 5.v volts +/- .3 volts if I remember right and then it will run like you never saw it run before!!!
Where do you got that Info the the Torque Converter eats more Power than a Manual Car? The Torque Converter is only active in the starting Phase, and while changing Gears. When the Gear is in, the Torque Converter is inactive, and the Car have the same Driveshaft Connection like a Manual Car.
@@kallo182 Science says the torque converter is slipping while it is working just picture a electric fan blowing against another fan that is unpowered like a pinwheel that one is the transmission while the one bolted to the flywheel is the engine. that is how a automatic transmision works. I am so glad I have a Richmond 5 speed manual in my autocross car and blast through the gears as fast as I can floor it and bang through the gears with 6500 RPM shifts !
@@lilibethdoherty295 WTF? The Torque Converter ist like a Clutch in a Manual Trasmission. It is only there to change Gears. When the Gear is changed, the Torque Converter is switched off. Like i wrote in my first Comment. You dont have to explain me how it works. I know how it works. Do you actually think the Car drive all the Time with the Torque Converter??
Hi Billy, I know. I’ve seen a lot on TH-cam and never saw one like that either. It was a Mustang Dyno. That’s all I know. Thanks for commenting. Take care!
Go wild with the turbo! They did a vid on engine masters where a small block Chevy nothing special with just a turbo and 12lbs boost made 500 hp!!!! They took it all the way until it exploded at like 560 with 20 lbs boost!!!
@@sonnydemichele4903 5.3 swap with a turbo kit you would be fast as hell and around 500hp .... try to find a truck with a 5.3 2wd and swap over everything needed .... then buy one of those ebay turbo kits ....
Your engine was probably producing the full rated HP... figure a 20% loss, so that would bring you down from 245 HP ('91 auto) to 201. The limiting factor here is the intake. Your torque takes a nosedive after 3300 RPM. Given that HP = torque X RPM, you can see that as torque drops, HP will drop. If you want more real power, at a minimum you need to get the plenum, runners, and baseplate ported, then maybe run the GM Hot Cam or similar aftermarket cam. The TPI intake was originally designed for a 305 ci engine, and it's undersized for the 350. It will give good performance under 4K RPM but falls on its face after that. The LT1 found in '92 and later engines has 30 more HP, solely due to the Miniram manifold... the same manifold on the L98 will give you the same HP. I have a '91 roadster with the 6-speed. If you want to spend $3K, then a new cam, a new manifold, and new heads, and you'll get 350 HP or thereabouts at the crank, 300 at the wheels. Or, spend another $4K and get a 383 and you'll get well over 400 HP and a car that will do 0-60 in under 4 seconds.
Hi John, nice comment. Thank you! I agree with the torque dropping after 3300 RPM. Very bad drop, lol. How do you do the ported things and plenum runners? Are they parts you buy or what? Thanks again. Merry Christmas!
@@Doulop You can go to a company like Extrude Hone and they will port your intake (plenum, runners, baseplate). Or, you can replace the TPI with another intake, e.g., the Miniram (that loses the TPI look). Or you can go with an aftermarket system like a FIRST TPI that is like the factory TPI in design but on steroids, and flows 30% more air without porting (and can be ported to flow much more, e.g., via Extrude Hone). I think that on a stock or rebuilt 350 L98, either the Extrude Hone option or the FIRST TPI with the GM Hot Cam would bring you up to near 300 HP at the rear wheels (RWHP), and that would let you run 0-60 in the mid-4 second range. If you can do the work yourself, the FIRST TPI and the cam would run you under $2K. Your engine had 100K miles when the video was made. I'm sure it has more now. If I was doing this, I'd get a 383 stroker short block, get AFR 195 heads on it, call Crane Cams for a recommended hydraulic roller cam for 2500 to 6000 RPM and 1.6:1 ratio roller rocker arms, and get a FIRST TPI manifold. That package would produce well in excess of 400 crank horsepower, and likely well over 350 HP at the wheels. Imagine your car with twice the RWHP, yet it would be tractable and driveable, with good fuel economy if you kept your foot out of it... and VERY fast, about as fast as you could safely use on the street. My '91 L98 has 52K miles on it, and the Hot Cam and a full Borla exhaust. It runs 0-60 just over 5 seconds. My cheap performance fix would be the FIRST TPI intake and AFR heads.
I have to disagree with you on some things, I don't believe an LT1 intake will bolt on a L98 and its not just put it on and get the HP and torque of the LT1 if it was Chevy would have just changed the manifold instead of engineering a new motor. The LT1 was quite a bit different, one difference is the L98 had a distributor in back of the intake and I believe coil packs back there where the LT1 had a distributor above the crank shaft and say what you will about optispark but it was far superior controlling spark then anything before it, so I don't believe the LT1 manifold will allow for the rear distributor. The LT1 also had reverse coolant flow which enabled higher compression ratio and I would have to go out in the cold garage and look but I don't think the coolant runs through the intake but I think it did on the L98. But the real thing is why do you want to beat those 30 year old cars up remember its more than an engine, when they were made Chevy had no intention of making that car to be still on the road in 30 years or over 150,000 miles, it was a little more than 10 years earlier that the odometers only went to 99K. I have a 92 LT1 vette in black rose metallic that 10 years ago was getting close to being a parts car and I have been resurrecting it ever since, you destroy yours and it makes mine just a little more rare and it keeps the swap meets running.
@@jaymortensen642 On the subject of intakes: The LT1 intake can be modified to work on an L98. A few people have machined them to fit small cap HEI distributors. Obviously a TPIS mini ram or FIRST intake would be an easier swap though. The L98 113 heads and aluminum LT1 heads flow basically the same in stock form(190-ish cfm). Combining the TPIS intake and an LT4 "hot cam" kit with some tuning seriously wakes these motors up. Port the 113's with 2.00/1.56 LT4 valves and they'll support over 500hp. On the subject of reverse cooling: Chevy had to bump the LT1's compression up because the heads run so cold. Aluminum heads already retain less combustion heat in the cylinder than iron heads and produce less power for a given static compression ratio. By cooling the heads first, the LT1 really doesn't have a huge advantage over the L98. On the subject of modifying older C4's: There are still guys out there modifying and racing C2 and C3 Vettes. The great thing about fiberglass is it doesn't rust, and with Corvettes being body on frame there's nothing underneath that really can't be rebuilt or upgraded. It not hard, or relatively expensive, to build a serious autocross or road race car from a decent condition C4.
Back on the mid 90s, my my L98 vette and bother race each other and hyper chip(2 to 3 faster(,air foil(half a car hole shot),k N filter(half a car lenght),free flow exhaust borla true duals not cats(3-5) car lenghts.so about 45-60hp is realestic.
45 maybe. 60, not realistic. Not with an L98. Don't get me wrong, great motor, had 2 of them. Love the torque of an L98. That's what they were designed for. 340 lbs stock, in a '90 Formula.
I also ha e a 91someone painted it black. It was the light blue. Can’t remember what the color was called. I’m going to tear it down. I have had it fir 10 years a barely get to drive it. I fix one thing and driver for 3-4 weeks at tops. I’m getting pissed. I dumped a lot into last year and drove it fir 2 weeks and it’s running like shit. My ZO6 2016 is white and black. There is no comparison. Lol but want to just drive the 91 around town.
Mustang dyno or dynojet? If it’s a dynojet it’s more around 180-190. For whatever reason dynojets don’t give the right numbers. Only reason I say this is cause my friend has an 85 C4 vette and said he was half throttle when driving with me, so I’m pretty interested in how much these cars really make
Hey brother I am currently in the market for a c4 I have been watching your channel for a long time and I appreciate your content, do you have any suggestions and can I get your contact info ie.email to ask you a few c4 questions?
Hey, thanks so much for reaching out!! I would love to help answer your questions. I am glad you like the channel. I appreciate that. In the about section of my page, is my business email. Feel free to email me :)
I had many C4 Corvettes but my 300 hp 1995 LT1 was killer i got caught doing 100 mph on the highway the cop let me go with a small fine he could of towed my car and gave me huge fines so i ended up selling it so i do not lose my drivers
@@Doulop I have the 1996 LT1. And I would trade it for a similar '91 in a heartbeat. All you are missing out on is the Optispark, and I wouldn't wish that on my worst enemy. Doesn't matter how fast it goes if it leaves you stranded without warning.
@@Doulop Seriously. You dodged a 50 cal. bullet. For a base model, you scored the perfect year C4, IMO. Five years with a C4 daily driver has been quite the education. If I had known then, I would've kept looking for a '91. No question. My theory is that they only did a band-aid fix to the Optispark after 3 years of trouble because everyone except the door hangers had moved on to the C5.
@@RARenfield my top rad hose blew and antifreeze took out my optispark left me stranded on the highway late at night cost $900 after tow and fixing it that is the only shitty thing about the LT1
@@Doulop no problem, after a dozen years of owning a C4 L98 and competing with the car in SCCA Autocross I have come across a number of problems, and can offer solutions but only on that specific engine and the ZF 6sp combo.
Dude. In about 1971 the industry went to SAE Net horsepower and torque rating system which means, at the wheels. If your engine is only putting out 201 HP, it's hurting. BAD. My bone stock 1990 Formula 350 with L98 (rated 245 HP) put out 251 HP at the wheel on the dyno.
@@Doulop I always said I would not buy something and never drive it but now I've got 11 cars in my collection that might see 10 miles a year I dont know where i went wrong
Hahahahaha!!! Sounds like a good problem to have, though :) Someday, when my wife and I get our debt paid off, I want to add another Corvette to my collection! Can’t wait
Mine is a 1991. Yeah, I never knew the years were different until I was looking at them at the Corvette show and saw the later 90’s and I was surprised.
Impressive, considering, age, mileage, etc. you can really tell its a TPI-L98, she just struggles to reach higher rpm's, they just don't want to rev much past 4800-5000 rpm when stock. But still impressive.
@@jackmehoff4613 Yep, the runners where made for the 305 TPI Motor. Shorter runners and a Cam would move the power up the RPM range =More HP and Less Low end Torque.
Chrysiotis I’m actually looking to get one From 1-10 how you rate your experience with the C4 I want one for the classic look and LT1 motor Newer corvettes are too played already exception of the C7 and C8 those are cool af
@@juliobello4561 I would give it a 9 since nothing is perfect. The biggest gripe I got is that it's not the easiest car to get in and out of if you got a few extra pounds. Once inside though it feels like an airplane cockpit. If you get one get the 2 factory service manuals and the ""corvette fuel injection and engine management"" book. You can find them all on ebay. I want to know how everything works and how to do most repairs myself because we are talking 30 year old vehicles that even though are very reliable they still need maintenance and repairs. And in today's world paying a good mechanic to do your work costs a lot of money. Not every repair facility has knowledgeable mechanics to work on them. A good scanner is extremely helpful to have, I use a Snap On MT2500 found on ebay for a fraction of their original price. Great cars overall and I'm loving owning one. Yes the newest car have more horses but 300 plus a few more with easy mods are plenty for me plus 28mpg on the highway. Good luck if you get one, just buy a nice one , they are not expensive. Don't buy a beater, costs a lot of money to restore, especially interior parts.
@@Doulop If you are curious of the history here....and this comes straight from GM-Buick engineers, the 86 Vette was 230HP. The 86 Buick GN was 235HP. In 87 Vette was upped to 240HP. The 87 GN, with zero changes in the engine, was stated as 245HP. For ‘88 the Vette was upped to 250HP. See the trend here? Literally Buick was upping the Vette. The sole reason the ZR-1 was made was to smash the Buick GNx. I love the history here. Source for above info, Documentary Black Air. Its on youtube and its cool to listen to the people responsible for the Buick development and part of their drive was to top the Vette. Despite corporate orders not to do so. Cool stuff for C4 owners to know the lineage.
5000 + rpm makes ZERO difference in power, that tuned port does ZERO beyond that point. The runner length kills ANY chance of making high RPM power. By removing it and replacing it with a TPIS miniram and a set of inch and 3/4s headers will make more power than anything else you do to it. Adding an LT4 hotcam, Manley 22410 springs, and 1.6 ratio roller rockers and youll easily make 125 horsepower touching the ground. Ive built and raced too many of these Corvettes to waste time on the bolt on crap that doesnt work.
That’s why I enforced the words “says it should” hahaha because I know that’s kind of crazy. We shall see in 2020 what I currently have. Thanks for commenting, take care Dr M.
This is so stupid, actually disappointing. Just because and engine has has 100k or 150k doesn't mean it should be down on power unless the engine is shot This is like buying a used car with 150k and the owner talks it up, then it has all kinds of issues and the owner says what do you expect it has 150k...
Thanks for your comment. I don't know. I have heard several times that cars typically lose some power with age due to wear and tear. Oh well. Mine still runs great.
@@Doulop That is a myth. Some wear and tear can actually increase power! To a point... My car is 14 years old and over 150k miles and have gone up against new cars that supposedly had more HP and mine would outpull them.
That’s awesome! I wish I could have driven my car brand new but I couldn’t. I was 2 years old. She still runs great and has great power. Thanks for your comments!
People who follow my channel and watch every video do care. Sorry to disappoint. There are plenty of other C4 videos out there that have the information you’re looking for.
Lol puts out about 10-15 hp and about 20ft lbs of torque more than a tiny 5.0/302 mustang sad considering a corvette has 48 cubic inches more and when new cost twice what a mustang of the same year cost. Pathetic.
If you get super critical, yeah, you are right. Haha! Thanks for watching! Most people I watch on TH-cam don’t consider an exhaust beyond stock but you are correct.

the 91 l98s are rated at 245hp so thats right on par with the rating from Chevrolet

He said there's an idle problem so that's what's taking some time . I've heard before that happens with l98's
Gotcha! It will all work out!
I would bet money you gained less than 15 HP from the mods going by experience. You need a ram intake along the lines ot the LT1 style to make good numbers. The tuned port is a torque monster not a high HP intake. I always love the look of the tuned Port though. It just looks so cool.

Hi TellMeHD, thanks so much for watching the videos. That means a lot to me. Honestly, when I was 19 (when I bought the car) I knew very little about the C4. I knew a lot about the C6 because it had just came out a few years earlier. I had no idea what I was buying. These days, I would have done a ton of research. To answer your question, I often wish I would have gotten a later year C4 with the LT1. That being said, though, I wouldn’t trade my current car for one. I love that car so much! I am definitely doing another dyno this spring as long as I can figure out why my radiator fans aren’t running. Thanks for commenting. Take care!
Uh,that would be 96 LT4. All had ZF 6 speeds.Factory rated @330hp. Most all of them,including mine,Dyno higher. They didn't want to outshine the new body style 97(C5) which was 345hp. Love the C4 content.
I just drag my 91 C-4 out of the pasture. Five yrs ago had little disagreement with my community speed trap. So no tickets and park it. Finishing C-3 496 NOS full cage car. Plus DVR cameras witness to deal with speed trap.
Speed traps are lame
Impressive!!! I hear you man!!! hahaha Ive had a few corvettes tho none were the awesome HP ones one was a UGLY 74 Brown C3 witht he L48 and factory 4 speed with a bad 2nd gear synchronizer so u had to hold it in hahaha my other vette was a 86 with the l98 auto..... see back in the 80's that was fast for the day..since then I got into F-bodys cars because u cud smoke vettes with their own engines.
Thanks for watching, Mark. All good points. I never heard of an f-body but I will take your word for it.
@@Doulop a F-Body is all Camaro's and Firebird's including all gens
Never heard that before. Thanks Mark!
I'm an original owner of a '91 coupe with 6 spd and adjustable suspension. have driven it all over and taken it to the limits on the curvy's in the Ozark mountains in MO and AR. Fastest I've ever been was 140mph. It is still bone stock with the original exhaust and even the windshield wiper blades, lol. Would like to have a bit more sound. Are those Borla exhausts you have on this one?
Hi Steven, so cool. I responded to your message on Instagram. Did you get it?
Love the content. Where did you buy your headlight motor from ? My is starting to clunk noise
Thanks so much! I appreciate that. I never had to replace a headlight motor yet. Sorry man!
I have a 1990 ZR1 with 38K mile , black on black... Thinking about selling it... A was told a set of headers, a chip, and convert it to a single-stage flywheel should bring the HP to 450-470 . It came stock detuned and could still hit 187 MPH
Wow!! That’s is awesome! Beautiful car you got there! Thanks for commenting. Take care!
The '89 and '90 ZR1s at 375 hp were actually quicker than later models, except for maybe the '93-95 with 405 hp.
Joshua Echt I would love to drive the ZR1. Epic!! Thank for commenting. Take care!
I have a 93 c4 has 40k miles, when I put it away for the winter, it seemed to be running pretty rich. Has all new plugs/wires
Hi Jeff, I’m not sure why that would be. I’m really sorry. I don’t know much about engines, I wish I did. Good luck on finding the issue. Take care!
93? that would be an LT1. opti spark maybe? i have a 96 Z28 and i had to replace mine once.
@@ad356 The '93 was a first-generation, non-vented Optispark. Even still, 40K miles is an early fail for OEM. Once you replace it, you'll be doing it over and over again as Mitsubishi and Delco no longer make them. Factory stopped selling new units years ago. Final prices were around $1,200 for the part. $50 Chinese knockoffs are just as reliable as a $600 MSD unit. I hope you kept your old OEM Optspark. You can harvest the highly coveted Mitsubishi optical sensor and repurpose it. Rebuilders are paying $$$ for the discontinued sensors.
@@RARenfield i have a delhpi unit i bought back in 2014 when i bought the car. not sure what sensor it has
Some folks add aftermarket air box and filters that are lightly oiled and mess up the MAF sensor. And check for the PROPER Factory plugs and wires being used.
Plus the chip took shift points up to 5500, on are stock L98 engines automatics.no 94- 97 lt1 z28 could see me, or my brother.lol
5500 shift points is fine and dandy. But L98's are out of steam and pretty much stop pulling hard at around 4500.
That’s a very tall statement lol
I too have gone up and down in weight 😊
It’s so frustrating. I’ve gained a lot since COVID began. So mad at myself.
Did you sync your TPS and Control valve it just seems a little lagging. Those MPH numbers should go up a litttle faster. I did mine to read I believe 5.4 volts and when they are synced it's crazy how fast it gets.
My year car doesn’t have adjustable TPS. Just plug and play!
@@Doulop there are two bolts that hold it on right? There are 2 arks or curved slots that the bolts are in and thats where you move the TPS.
@@Doulop if it's moved 1/32 '' that will change 5 volts on the meter it's very finicky
@@Doulop that's why the TPS has those wide slots where the bolts screw in so you can move it around up down forward back angled up angled down ect.
is your idle ok because you will notice you can turn the screw to adjust it and the computer will just go back to where it was. You need to bypass the computer unplug the idle control valve set your idle speed plug it back in then do your TPS to 5.v volts +/- .3 volts if I remember right and then it will run like you never saw it run before!!!
The torque converter eats 5% more power than a manual vette, 15 % loss for a manual 20 % for the power sapping automatic.
Thanks for the information. I appreciate it!
Shouldn’t it be 10-15% for manual, 15-20% auto? AWD vehicles are in the 20-25% range
Where do you got that Info the the Torque Converter eats more Power than a Manual Car?
The Torque Converter is only active in the starting Phase, and while changing Gears.
When the Gear is in, the Torque Converter is inactive, and the Car have the same Driveshaft Connection like a Manual Car.
@@kallo182 Science says the torque converter is slipping while it is working just picture a electric fan blowing against another fan that is unpowered like a pinwheel that one is the transmission while the one bolted to the flywheel is the engine. that is how a automatic transmision works. I am so glad I have a Richmond 5 speed manual in my autocross car and blast through the gears as fast as I can floor it and bang through the gears with 6500 RPM shifts !
@@lilibethdoherty295
WTF?
The Torque Converter ist like a Clutch in a Manual Trasmission.
It is only there to change Gears.
When the Gear is changed, the Torque Converter is switched off.
Like i wrote in my first Comment.
You dont have to explain me how it works. I know how it works.
Do you actually think the Car drive all the Time with the Torque Converter??
I've seen a lot of Dynomometers over the past 45 years and I ain't never seen one like that. Who makes that thing?
Hi Billy, I know. I’ve seen a lot on TH-cam and never saw one like that either. It was a Mustang Dyno. That’s all I know. Thanks for commenting. Take care!
@@Doulop Do they ever adjust anything on the Dyno, or is it just for informative reasons?
'91 is my favorite year for the C4
amen!! Thanks for watching!
@@Doulop
Do you still have your Vette?
Absolutely. Never won’t have it lol. I just made a video on it three weeks ago.
I'm trying to bump up the power in my '96...not sure if I should bore,and stroke...or turbo...turbo might be cheaper
Go wild with the turbo! They did a vid on engine masters where a small block Chevy nothing special with just a turbo and 12lbs boost made 500 hp!!!! They took it all the way until it exploded at like 560 with 20 lbs boost!!!
Wow!! That’s crazy!
@@sonnydemichele4903
5.3 swap with a turbo kit you would be fast as hell and around 500hp .... try to find a truck with a 5.3 2wd and swap over everything needed .... then buy one of those ebay turbo kits ....
Sounds like the gears were to long for that show thing lol. Took forever to try getting even close to the limiter.
Yeah, I’m assuming they are stock gears. I know nothing about gearing.
That was great. How many miles do you have on her now? Time to start saving for a 383 stroker.
Hi David, I have 115,000 on her now. Thanks for complimenting the video. Take care!

I’m not sure. Sorry man! Thanks for commenting. Take care!
Your engine was probably producing the full rated HP... figure a 20% loss, so that would bring you down from 245 HP ('91 auto) to 201. The limiting factor here is the intake. Your torque takes a nosedive after 3300 RPM. Given that HP = torque X RPM, you can see that as torque drops, HP will drop. If you want more real power, at a minimum you need to get the plenum, runners, and baseplate ported, then maybe run the GM Hot Cam or similar aftermarket cam. The TPI intake was originally designed for a 305 ci engine, and it's undersized for the 350. It will give good performance under 4K RPM but falls on its face after that. The LT1 found in '92 and later engines has 30 more HP, solely due to the Miniram manifold... the same manifold on the L98 will give you the same HP. I have a '91 roadster with the 6-speed. If you want to spend $3K, then a new cam, a new manifold, and new heads, and you'll get 350 HP or thereabouts at the crank, 300 at the wheels. Or, spend another $4K and get a 383 and you'll get well over 400 HP and a car that will do 0-60 in under 4 seconds.
Hi John, nice comment. Thank you! I agree with the torque dropping after 3300 RPM. Very bad drop, lol. How do you do the ported things and plenum runners? Are they parts you buy or what? Thanks again. Merry Christmas!
@@Doulop You can go to a company like Extrude Hone and they will port your intake (plenum, runners, baseplate). Or, you can replace the TPI with another intake, e.g., the Miniram (that loses the TPI look). Or you can go with an aftermarket system like a FIRST TPI that is like the factory TPI in design but on steroids, and flows 30% more air without porting (and can be ported to flow much more, e.g., via Extrude Hone). I think that on a stock or rebuilt 350 L98, either the Extrude Hone option or the FIRST TPI with the GM Hot Cam would bring you up to near 300 HP at the rear wheels (RWHP), and that would let you run 0-60 in the mid-4 second range. If you can do the work yourself, the FIRST TPI and the cam would run you under $2K.
Your engine had 100K miles when the video was made. I'm sure it has more now. If I was doing this, I'd get a 383 stroker short block, get AFR 195 heads on it, call Crane Cams for a recommended hydraulic roller cam for 2500 to 6000 RPM and 1.6:1 ratio roller rocker arms, and get a FIRST TPI manifold. That package would produce well in excess of 400 crank horsepower, and likely well over 350 HP at the wheels. Imagine your car with twice the RWHP, yet it would be tractable and driveable, with good fuel economy if you kept your foot out of it... and VERY fast, about as fast as you could safely use on the street.
My '91 L98 has 52K miles on it, and the Hot Cam and a full Borla exhaust. It runs 0-60 just over 5 seconds. My cheap performance fix would be the FIRST TPI intake and AFR heads.
Thanks again, John! Merry Christmas!
I have to disagree with you on some things, I don't believe an LT1 intake will bolt on a L98 and its not just put it on and get the HP and torque of the LT1 if it was Chevy would have just changed the manifold instead of engineering a new motor. The LT1 was quite a bit different, one difference is the L98 had a distributor in back of the intake and I believe coil packs back there where the LT1 had a distributor above the crank shaft and say what you will about optispark but it was far superior controlling spark then anything before it, so I don't believe the LT1 manifold will allow for the rear distributor. The LT1 also had reverse coolant flow which enabled higher compression ratio and I would have to go out in the cold garage and look but I don't think the coolant runs through the intake but I think it did on the L98. But the real thing is why do you want to beat those 30 year old cars up remember its more than an engine, when they were made Chevy had no intention of making that car to be still on the road in 30 years or over 150,000 miles, it was a little more than 10 years earlier that the odometers only went to 99K. I have a 92 LT1 vette in black rose metallic that 10 years ago was getting close to being a parts car and I have been resurrecting it ever since, you destroy yours and it makes mine just a little more rare and it keeps the swap meets running.
@@jaymortensen642
On the subject of intakes:
The LT1 intake can be modified to work on an L98. A few people have machined them to fit small cap HEI distributors. Obviously a TPIS mini ram or FIRST intake would be an easier swap though. The L98 113 heads and aluminum LT1 heads flow basically the same in stock form(190-ish cfm). Combining the TPIS intake and an LT4 "hot cam" kit with some tuning seriously wakes these motors up. Port the 113's with 2.00/1.56 LT4 valves and they'll support over 500hp.
On the subject of reverse cooling:
Chevy had to bump the LT1's compression up because the heads run so cold. Aluminum heads already retain less combustion heat in the cylinder than iron heads and produce less power for a given static compression ratio. By cooling the heads first, the LT1 really doesn't have a huge advantage over the L98.
On the subject of modifying older C4's:
There are still guys out there modifying and racing C2 and C3 Vettes. The great thing about fiberglass is it doesn't rust, and with Corvettes being body on frame there's nothing underneath that really can't be rebuilt or upgraded. It not hard, or relatively expensive, to build a serious autocross or road race car from a decent condition C4.
You should follow Richard Holder if you are not already.
Thanks a lot! I looked him up!
What all did you use to make your enclosure
Hey man, here is a dedicated video of it :) thanks a lot! th-cam.com/video/ge3_dBOSYjE/w-d-xo.html
What size rims and tires were on the car in this video. I have a 89 that I’m looking to put some chrome on

Heck yes!!!
How much does it cost to put a car on the dyno
It cost me $150 and that was several years ago.
I took a guess at 200 and was right 🤟🏻
Right on :)
Back on the mid 90s, my my L98 vette and bother race each other and hyper chip(2 to 3 faster(,air foil(half a car hole shot),k N filter(half a car lenght),free flow exhaust borla true duals not cats(3-5) car lenghts.so about 45-60hp is realestic.
Nice! Thanks a lot man! My next video will go over all those things I added. I will get her dyno’d again next year. Thanks for commenting. Take care!
45 maybe. 60, not realistic. Not with an L98. Don't get me wrong, great motor, had 2 of them. Love the torque of an L98. That's what they were designed for. 340 lbs stock, in a '90 Formula.
Amen! That’s why I wasn’t holding my breath!
I also ha e a 91someone painted it black. It was the light blue. Can’t remember what the color was called. I’m going to tear it down. I have had it fir 10 years a barely get to drive it. I fix one thing and driver for 3-4 weeks at tops. I’m getting pissed. I dumped a lot into last year and drove it fir 2 weeks and it’s running like shit. My ZO6 2016 is white and black. There is no comparison. Lol but want to just drive the 91 around town.
I am jealous of the Z06. I hope you can get your 91 in running order.
Mustang dyno or dynojet? If it’s a dynojet it’s more around 180-190. For whatever reason dynojets don’t give the right numbers. Only reason I say this is cause my friend has an 85 C4 vette and said he was half throttle when driving with me, so I’m pretty interested in how much these cars really make
I honestly have no idea. This Dyno was done over 10 years ago and I forget what it was.
Hey brother I am currently in the market for a c4 I have been watching your channel for a long time and I appreciate your content, do you have any suggestions and can I get your contact info ie.email to ask you a few c4 questions?
Hey, thanks so much for reaching out!! I would love to help answer your questions. I am glad you like the channel. I appreciate that. In the about section of my page, is my business email. Feel free to email me :)
I had many C4 Corvettes but my 300 hp 1995 LT1 was killer i got caught doing 100 mph on the highway the cop let me go with a small fine he could of towed my car and gave me huge fines so i ended up selling it so i do not lose my drivers
Hahahahaha, lesson learned! Lol. I would love to drive something that fast. Sorry you had to get rid of it. Thanks for commenting. Take care!
@@Doulop I have the 1996 LT1. And I would trade it for a similar '91 in a heartbeat. All you are missing out on is the Optispark, and I wouldn't wish that on my worst enemy. Doesn't matter how fast it goes if it leaves you stranded without warning.
RARenfield, I’ve not heard got things about the OptiSpark. Glad I don’t have that!!
@@Doulop Seriously. You dodged a 50 cal. bullet. For a base model, you scored the perfect year C4, IMO. Five years with a C4 daily driver has been quite the education. If I had known then, I would've kept looking for a '91. No question. My theory is that they only did a band-aid fix to the Optispark after 3 years of trouble because everyone except the door hangers had moved on to the C5.
@@RARenfield my top rad hose blew and antifreeze took out my optispark left me stranded on the highway late at night cost $900 after tow and fixing it that is the only shitty thing about the LT1
What motor do you have?
L98
Is your 91 running an L98?
Hi Arthur! Yes, sorry, I should have mentioned that in the video. Thanks for watching and commenting. Take care!
@@Doulop no problem, after a dozen years of owning a C4 L98 and competing with the car in SCCA Autocross I have come across a number of problems, and can offer solutions but only on that specific engine and the ZF 6sp combo.
Arthur Grant, thank you! I would love to do some auto cross sometime :)
Dude. In about 1971 the industry went to SAE Net horsepower and torque rating system which means, at the wheels. If your engine is only putting out 201 HP, it's hurting. BAD. My bone stock 1990 Formula 350 with L98 (rated 245 HP) put out 251 HP at the wheel on the dyno.
Hi Jack, who knows? I’m just sharing what the DYNO showed. Thanks for commenting. Take care! Merry Christmas!
incorrect, net horsepower doesn’t mean power to the wheels.

Yes, the later C4 seats were hideous. Mine are awesome!
What year are they. Mine is a 94. I like your better.
Mine is a 1991. Yeah, I never knew the years were different until I was looking at them at the Corvette show and saw the later 90’s and I was surprised.
Impressive, considering, age, mileage, etc. you can really tell its a TPI-L98, she just struggles to reach higher rpm's, they just don't want to rev much past 4800-5000 rpm when stock. But still impressive.
Thanks a lot. I agree. Lots of low torque but nothing up top, for sure. Thanks for commenting. Take care!
@@Doulop do a lt1 conversion be intake
hell yeah.. they were still fun.... there tq monsters when built up
One year ago ?????? 2012 OKKkKkKAY
Huh??
If you just put a cam in it, that in turn will shift the torque of the engine higher in the rpm band. You should see between 50-100whp
Hi Ryan, a cam would be sick! Maybe some day. Pretty expensive to do at this point. Thanks for commenting. Take care. Merry Christmas!!
For that type of gain you would also need some serious induction upgrades. L98s suffer from low flowing intakes.
@@jackmehoff4613 Yep, the runners where made for the 305 TPI Motor.
Shorter runners and a Cam would move the power up the RPM range =More HP and Less Low end Torque.

Chrysiotis I’m actually looking to get one
From 1-10 how you rate your experience with the C4 I want one for the classic look and LT1 motor
Newer corvettes are too played already exception of the C7 and C8 those are cool af
@@juliobello4561 I would give it a 9 since nothing is perfect. The biggest gripe I got is that it's not the easiest car to get in and out of if you got a few extra pounds. Once inside though it feels like an airplane cockpit. If you get one get the 2 factory service manuals and the ""corvette fuel injection and engine management"" book. You can find them all on ebay. I want to know how everything works and how to do most repairs myself because we are talking 30 year old vehicles that even though are very reliable they still need maintenance and repairs. And in today's world paying a good mechanic to do your work costs a lot of money. Not every repair facility has knowledgeable mechanics to work on them. A good scanner is extremely helpful to have, I use a Snap On MT2500 found on ebay for a fraction of their original price. Great cars overall and I'm loving owning one. Yes the newest car have more horses but 300 plus a few more with easy mods are plenty for me plus 28mpg on the highway. Good luck if you get one, just buy a nice one , they are not expensive. Don't buy a beater, costs a lot of money to restore, especially interior parts.

At or around 9:45 its not 250hp stock its 245hp. Either way pretty much expected the trans would soak up 45hp or so. Good video.
Hmm, you are right. I thought it was 250. Thanks for correcting me! Thanks for watching.
@@Doulop If you are curious of the history here....and this comes straight from GM-Buick engineers, the 86 Vette was 230HP. The 86 Buick GN was 235HP. In 87 Vette was upped to 240HP. The 87 GN, with zero changes in the engine, was stated as 245HP. For ‘88 the Vette was upped to 250HP. See the trend here? Literally Buick was upping the Vette. The sole reason the ZR-1 was made was to smash the Buick GNx. I love the history here. Source for above info, Documentary Black Air. Its on youtube and its cool to listen to the people responsible for the Buick development and part of their drive was to top the Vette. Despite corporate orders not to do so. Cool stuff for C4 owners to know the lineage.
5000 + rpm makes ZERO difference in power, that tuned port does ZERO beyond that point. The runner length kills ANY chance of making high RPM power. By removing it and replacing it with a TPIS miniram and a set of inch and 3/4s headers will make more power than anything else you do to it. Adding an LT4 hotcam, Manley 22410 springs, and 1.6 ratio roller rockers and youll easily make 125 horsepower touching the ground. Ive built and raced too many of these Corvettes to waste time on the bolt on crap that doesnt work.
Friend, I say this with kindness:
64hp from bolt-ons and a chip?
Nope.
That’s why I enforced the words “says it should” hahaha because I know that’s kind of crazy. We shall see in 2020 what I currently have. Thanks for commenting, take care Dr M.
Dr M wisdom 25hp at most that’s if the part is compatible with the factory software.
It comes from factory with only 245 hp not 250.
Yeah, you are right. I found that out from some others too. Thank you!
Unless the car came with the performance rear end. With that you also got the ZR1 exhaust. Were rated at 250 with that combo
You need to find a new dyno guy. He is extremely unsafe
That’s the first dyno I ever experienced. What was unsafe about it?
I will disappoint you, said no v8 ever
Amen!!! Loved your comment. Thanks Alan!
This is so stupid, actually disappointing.
Just because and engine has has 100k or 150k doesn't mean it should be down on power unless the engine is shot
This is like buying a used car with 150k and the owner talks it up, then it has all kinds of issues and the owner says what do you expect it has 150k...
Thanks for your comment. I don't know. I have heard several times that cars typically lose some power with age due to wear and tear. Oh well. Mine still runs great.
@@Doulop That is a myth. Some wear and tear can actually increase power! To a point... My car is 14 years old and over 150k miles and have gone up against new cars that supposedly had more HP and mine would outpull them.
That’s awesome! I wish I could have driven my car brand new but I couldn’t. I was 2 years old. She still runs great and has great power. Thanks for your comments!
Dude no one is asking you about weight or your glasses just show the car
People who follow my channel and watch every video do care. Sorry to disappoint. There are plenty of other C4 videos out there that have the information you’re looking for.
Lol puts out about 10-15 hp and about 20ft lbs of torque more than a tiny 5.0/302 mustang sad considering a corvette has 48 cubic inches more and when new cost twice what a mustang of the same year cost. Pathetic.
Yeah, pretty funny. It’s a small block, though, too. Doesn’t help.
I’d still rather drive a Vette than a raggedy Mustang any day.
Amen!!
It’s not stock, u have exhaust
If you get super critical, yeah, you are right. Haha! Thanks for watching! Most people I watch on TH-cam don’t consider an exhaust beyond stock but you are correct.
