Pause at 19:40 and study the torque curves. The 62mm turbo has more torque than all the big ones from 3500 to 6000 rpm, then is about the same up to 7700. At 4500 rpm, it's making 90 lb*ft more than the biggest turbo. Mid-range torque is what wins races. If you're going for a Bonneville speed record, and peak power is all that matters, go for a big turbo.
The mid range works best on the road course. When I raced motorcycles, My bike had great mid range. You have 12 turns,and 2 straights. I can pull a tenth of a second on each turn vrs only 2 straights.
@@mcfero1 Nonsense. Dynamic forces at 4500 rpm offset pressure forces to the point that rod compression is almost zero. 15 psi boost is not enough to stack the rods at any speed, even at 1500 rpm.
Modern engines in general are all performing very well; but I think the standouts are for sure Honda’s K series, GMs LS and now LT platform, and the Ford Coyote/Voodoo platform. The power potential in relatively stock trim for all these engines is truly amazing.
If you want to talk about innovation, look at koniseggs inline 3 cyl 1liter twin turbo engine that produces 600hp. I'll be the first to admit at this point it's not attainable at all to the average guy, but it's badass nonetheless! PS, I still like ls engines.
I'm so glad you don't discriminate engines. There is value in knowledge regardless of platform. I am looking forward to the ultimate power output with stock parts modified. Having the "soft spool" has been very helpful; for me with my RWD 4g63 car on no prep racing. Thanks for the time and energy
The stuff at about 18 minutes in to the end is exactly what I like to see. Not all of us want 800- 1000 hp. at the top. Id much rather have 1 or 200 ft.lbs of torque where I drive the car. Even if it mandated forged rods and pistons, to live.
When it breaks a piston or rod from the Big Bang I want to see aftermarket rods and pistons turned up until the factory sleeve fails on a k24(87mm) and k20(86mm), I feel like this would answer a lot of questions in the Honda world
I love the mid-frame (50trim/.63 or .48) for street daily and occasional fun time. (for my 2.5 baby Mopar) You get tons of tq early, but it is of course... a trade-off for top end charge via backpressure and untouched cylinder head. Love the content as usual!
The ease that you can make serious power these days is mind blowing. A K24 with that smaller turbo and 500hp would be amazing in virtually any car - wicked stuff.
Im running the g25-550.. Best turbo for the street by FAR.. Capable of high HP for its size, but has amazing response and low-end.. I am tuned on boost by gear, but I make peak boost around 4K which is awesome for the street. And with the k24, stock, it only revs to about 76-7800 anyway with power falling off around there anyway. I make 390whp and 340tq which I think is a phenomenal number for the street. And its more than enough.. I couldnt turn it up much even if I wanted to as I would just spin. Im working on my suspension and tire/rim now to make it as perfect as possible.. I am running Hondata Traction control as well. Not perfect but a nice addition to have as 1st and 2nd would be useless without it. I am also running PPG 1-2-3 and a gearX 4th with Syncrotech carbon package. Trans is holding up really well. Its INCREDIBLY loud though. And I purposely went with a softer mount with Hasports 62a but the drivetrain is still super loud. A bit annoying for a street daily as I want the car to be.. And yeah the HArdrace full bushing set likely doesnt help, but the car just feels so stable and planted. Gotta make comfort and luxury sacrifices for performance.
I'd imagine there are situations where the softer bottom end would help traction. and running them down on the top. But torque at the shift recovery point is important.
A super comparison! Thank you for doing it. I feel one thing you’ve confirmed is that the GT-45 (or any similarly sized turbo) is almost like a ‘no worries, just do it!’ size turbo for so many combos. It seems to work somewhere between excellently and ok on anything you’ve tried it on. I was really happy with mine on a 6.2 litre LS swapped Foxbody... Cheers!
Not into four cylinders... However, although the result turned out just exactly like I thought it would, I still enjoyed watching the turbo comparisons. And it is somewhat amazing just how efficient those little engines are.
Also from what I have learned a bigger turbo is better on V8 because back pressure can become an issue if you’re running a single turbo to compensate . a smaller Cam can give you torque sooner in the rpm while the turbo is for up top and no back pressure issues
This is one of the best turbo comparisons I've seen. Oh I've been a mechanic for 35 years and owned my own dyno tuning business for 16 year, So I have a turbo sitting around that was on my Supra and it made 550kw at the wheels, so i'm going to try it on my Honda K24a1 just for a laugh, will be taking the K24a2 head off my sons car if I can't find a K24A2 second hand engine, We don't have E85 at the pump anymore in N.Z. so thinking of WaterMeth setup. I want to keep the K24A1 bottom end to keep the compression down 9.6:1
@@cumbob I drove a Lotus 7 replica that had a 2.4 with mild(ish) cams and a 68mm Borg turbo that was supposed to make 400whp. It was enough to make that 1,600lb car almost uncontrollable at WOT.
Bro just an NA K24 swap with Bolt on would make that miata insane.. I mean with full bolt ons a K24a can make upwards of 240whp stock. On a chassis as light as a Miata, thats a lot of power. And you have NA reliability.
For the same amount of money that would take you to make 250whp on the stock engine you can swap it for a k24 and have a much better engine for the future
There's lots of guys turbo k swapping there miata these days. I have a 07 k24 civic si an think I wanna k swapped miata. Rwd k series would be so sick.
Lag disappears, with a small nitrous shot. Turbos love nitrous. It increases the volume of the exhaust gasses, as well as dropping the IAT's dramatically. Both of which is advantageous, when used on a turbocharged engine. Usually a small 50hp nitrous jet will add 50-70whp and 100wtq-150wtq. I have seen HUGE torque increases when nitrous is added to laggy turbo setups. This is because the nitrous turns a laggy setup, into a super responsive setup. Making a turbo spool 2k-3krpms earlier makes the torque output skyrocket. I had a stock shortblock sr20det gain over 300wtq after adding a 140hp shot. It also gained about 175whp. Made over 500whp and 500wtq on 93oct fuel, all on a stock shortblock with over 100k miles on her.
Richard. I noticed in this video you stated what timing you had in it. Could you start to maybe mention your timing number with the LS stuff? I think it would help some of us kind of know a ball park so we don’t scatter stuff.
SO... back to that request i made in your other video about testing a remote mounted turbo vs off the engine. Your immediate answer was "the engine dyno is not the ideal place for response rate changes". And yet here we are 5 days later testing response and power curve changes LOL. PS: I absolutely love your videos so keep up the good work!
The problem with remote turbos is that the exhaust cools down a lot on the way to the turbine. If you can insulate the hot side well there’s no difference, but that’s really hard
It’s funny that so many people think putting a bigger turbo is always the answer to making more power, when in reality upgrading the cams and intake manifold is going to give you the top end power people are looking for. And usually on less boost
I think the thing I appreciate the most is how affirmative you are of your blessings. You live a dream life(that I know you worked hard for) yet your humility and passion shine through. You are truly a man amongst mice.
Really awesome info. Great for all the people out there who learn visually and want comparisons. Shame you have to qualify so many statements, but it's important for people to learn, or sometimes unlearn what they have heard on the internet.
Great information! Can you show the affects of too big of a cam on a turbo engine? Essentially the difference between turbo cams and N/A cams on a boosted application.
The real question is with the smaller turbo running between 7 to 10 psi will the motor with rods and pistons and headstuds would it run good numbers and not blow up with a 93 octane tune instead of me having to run e85 because its hard to come by around here the closest thing to my house is 100 octane race fuel and its like $17 to $20 a gallon on a good day
This is exactly why I want to go 300WHP NA before boost. Lots of the other guys were talking about oh, high compression turbo is bad. Well, this seems to be within spec.
I dig that ur doing everything out there. I would b down with some more csb stuff like this since ls motors have doubled in price and r still a little complex with swap. Well more costly then complex. I'd like to learn more boost with carb. Especially E85 Configurations
I was hoping to see a boost pressure map. When did the turbo get to the commanded boost pressure? At what rpm? Your explanation was very interesting. I liked to see rpm vs hp graphed. I hope next time you can do rpm vs boost graph!
Also to add to this bigger turbo makes more power at lower boost such as 10 lbs on a small turbo may be 5 lbs on a big turbo which can have better charge temps I have also seen turbos with a .63 hot 78 cold that make 5lbs fast but get lazy at more boost over a .63 70 closer to equal wheels
Might be a very stupid question but can you/I run salt ice water in the intercooler? How fast would it start to cause problems if any? We learned when we were young that salt water will get way colder than plain water, it's how we got ice cold beer very quickly.
Rich Were do you think a G25-550.72ar would sit with this set up? It would be on the down hill side of the map. My curiosity is in how much sooner it would come on(ref screen shot 19:24 "5250 transition ")? I understand that wound be counter productive for the purposes of this test.
So much good info! The torque curves really show an interesting story about sizing the turbo. Having back pressure numbers would be interesting, too but torque is what moves the vehicle in any particular gear. This begs the question from the BBC with twin GT45s, how quickly did the torque come on compared to a single S475 or S480? The back pressure on that test, the twins, was extremely low-did that kill the mid-range torque? With almost 500 cu in, did it matter? So many questions, so little dyno time... Thanks so much Richard!
Also looking forward to the fully instrumented results, I think that water to air IC if they're done right can make a big difference to knock-limited performance and straight engine mass flow if you're not knock-limited.
Gt45 for the win lol! Under 750 ish hp that $163 sure seems like the ticket, especially on small cube LS motor. It handily out spooled the VS 7875 which we know is a great turbo for 800 plus hp.
It doesn't matter what engine you have, boost makes everything. Lol. Judson, always said, your stupid if you got one and stupid if you dont..ive done a few off the wall combos and made good power with crap that nobody thought would.
@@snakeballs8965 really good for a 2.4 liter... that’s like making 700 hp on a NA 5.7 LT1 or 625 hp on a coyote... all on stock bottom end and no boost. Honda makes great motors. The S2000 had the highest HP per liter (123.5) of displacement of any production car till it was beaten by the Ferrari 458 (124.5) in factory trim
How about an LFX gm V6 test?I'm sure the junkyards are full of them and they are becoming a popular swap because of how relatively compact they are with manifolds in the heads.Maybe a little boost and see what they are capable of doing and maybe finding some limitations
Please test one of those new electric turbos. I have seen some about them but it was putting out 8psi of boost for less than half the price for a turbo set up.
Those are for tiny engines. Wait for garretts 48 volt e turbo to come out. It's a normal turbo with electric aid to eliminate lag. www.garrettmotion.com/news/media/press-release/garrett-to-launch-industrys-first-electric-turbo/ Basically what they do in f1
@richard Holdener curious as to why 17* timing? Were you seeing knock? And was that at peak tq or were you ramping timing as rpm increased to keep peak hp climbing? Also curious what the back pressure was with using the stock exhaust manifold. I would guess that flow is being hurt at higher rpm and that’s why curve is falling off from the Na pulls.
FP turbo results look like a low back pressure with a large cam - as soon as back pressure creeps in on the others it'll drop power off pretty quick - that FP probably had 1:1 emap and imap or close to and lets the big cams eat.
Hey Richard great video as always great information fun to watch. I would love to maybe see u do a 3.6 LGX turbo twin turbo build how much boost cam it take. Maybe how much none aspirated power any bolt ons to improve power. Just a idea maybe for the future even a LFX 3.6 be cool idk keep up the great work always enjoy ur videos. Thanks Josh Gessinger
Has he done a video about ideal turbo for k24? Say I wanted 450-500hp or maybe 600hp on pump gas for street droving and Hiroshima 800-1200hp on e85 is that possible? What woukd be the best for steady power but also make the most peak? I have a 3582r and I make boost around 3500 and on pump gas and only about 10psi the tires spin in second but I feel it could use a little more in 4th and 5th. Do I just need to set up boost by gear or maybe woukd a differemt turbo be ideal? It's in a mr2 spyder
Great video, really appreciate the stepwise repeatable scientific approach that you take here. Regarding that biggest turbo, holding up at the top of the rev range, I believe that most likely relates to how the pressure difference across the engine (between inlet and exhaust) is developing. I'm guessing that biggest turbo still has positive DP in that high rpm range when the others are going to zero or negative. Just one man's opinion :)
If the dyno can do a 5000 rpm run i.e. 3000-8000 rpm, can you start to show v8 engines at 2000 rpm and up? Off the line power is important for heavier vehicles.
Please do a compound turbo on something to show benefits of usable power and see if the small charger actually chokes it out with big power or if it doesnt
Such a great video brother good job man!! Hey so what brand is the 62mm turbo do you have an affiliate link on where to purchase it? I want to do a budget turbo set up on my 1 of 1 kswapped Ford Festiva. If you could share any insight on a full budget build that would be fantastic. I’m new to the k24 but man they seems to make great power and stay fairly reliable even with a stock longblock. Any chance I’d be able to email you for a chat?

Seeing how much power the K24 can make NA is about what i was looking at getting with a turbo just because i got the A4 and finding cams for that thing sucks, makes good torque tbh, around 270hp with 10 psi, should boogie like a booger
I hope you make 1000 with this. I just don't think the stock sleeves will hold. Will be tuned in though! Id like to be proved wrong tbh and see it happen

@@richardholdener1727 I suppose that much is a given, what I am wondering is what the crank itself is able to withstand. I have been told the cast crank in my Mark 8 is only good for around 450 HP

I'd like to know what it can do with larger ring Gap and still stock internals on boost in your next test runs as well
Great information! Can you show the affects of too big of a cam on a turbo engine? Essentially the difference between turbo cams and N/A cams on a boosted application.
K24 is a rowdy little bastard. I have a spare j35 from a 05 odyssey I'd be willing to donate to research.
are you local
My family lives in the sonoma county area, I travel down there from bend oregon pretty often. I could drop it off somewhere.
The real question is with the smaller turbo running between 7 to 10 psi will the motor with rods and pistons and headstuds would it run good numbers and not blow up with a 93 octane tune instead of me having to run e85 because its hard to come by around here the closest thing to my house is 100 octane race fuel and its like $17 to $20 a gallon on a good day
I have a 75x82 1.10 ar on my cammed ls1 it lights up at 3k with load i really like that turbo
This is exactly why I want to go 300WHP NA before boost. Lots of the other guys were talking about oh, high compression turbo is bad. Well, this seems to be within spec.
Choose the biggest turbo and use boost controller to help spike the boost down low.
Blue and green. Which turbo is which? It just says k24a- Turbo-e85. The labeling is not clear.
I dig that ur doing everything out there. I would b down with some more csb stuff like this since ls motors have doubled in price and r still a little complex with swap. Well more costly then complex. I'd like to learn more boost with carb. Especially E85 Configurations
the supercharger compound would be awesome with the big hotside turbo
Love the channel, excellent information .
Here for all the boost
I was hoping to see a boost pressure map. When did the turbo get to the commanded boost pressure? At what rpm? Your explanation was very interesting. I liked to see rpm vs hp graphed. I hope next time you can do rpm vs boost graph!
What commanded boost pressure? This was using a bleed valve as shown on the video.
Also to add to this bigger turbo makes more power at lower boost such as 10 lbs on a small turbo may be 5 lbs on a big turbo which can have better charge temps I have also seen turbos with a .63 hot 78 cold that make 5lbs fast but get lazy at more boost over a .63 70 closer to equal wheels
6262 for the win
Please more data-IAT, I/E pressures....Thank you.
Might be a very stupid question but can you/I run salt ice water in the intercooler? How fast would it start to cause problems if any? We learned when we were young that salt water will get way colder than plain water, it's how we got ice cold beer very quickly.
YES YOU CAN-IT'S NOT GREAT ON ALUMINUM LONG TERM
Rich Were do you think a G25-550.72ar would sit with this set up? It would be on the down hill side of the map. My curiosity is in how much sooner it would come on(ref screen shot 19:24 "5250 transition ")? I understand that wound be counter productive for the purposes of this test.
I have not run that turbo
when is the k24 big bang
So much good info! The torque curves really show an interesting story about sizing the turbo. Having back pressure numbers would be interesting, too but torque is what moves the vehicle in any particular gear. This begs the question from the BBC with twin GT45s, how quickly did the torque come on compared to a single S475 or S480? The back pressure on that test, the twins, was extremely low-did that kill the mid-range torque? With almost 500 cu in, did it matter? So many questions, so little dyno time... Thanks so much Richard!
Also looking forward to the fully instrumented results, I think that water to air IC if they're done right can make a big difference to knock-limited performance and straight engine mass flow if you're not knock-limited.
I want to take a 2010 CRV and have some all-wheel-drive turbo fun.
This has been some good information on turbo choice.
Gt45 for the win lol! Under 750 ish hp that $163 sure seems like the ticket, especially on small cube LS motor. It handily out spooled the VS 7875 which we know is a great turbo for 800 plus hp.
Don’t even like hondas but still he makes it interesting
EVERY MOTOR DOES COOL STUFF
@@richardholdener1727 what about the chevy Iron Duke?
It doesn't matter what engine you have, boost makes everything. Lol. Judson, always said, your stupid if you got one and stupid if you dont..ive done a few off the wall combos and made good power with crap that nobody thought would.
@@slopoke22 this motor was making 300 crank na
@@snakeballs8965 really good for a 2.4 liter... that’s like making 700 hp on a NA 5.7 LT1 or 625 hp on a coyote... all on stock bottom end and no boost. Honda makes great motors. The S2000 had the highest HP per liter (123.5) of displacement of any production car till it was beaten by the Ferrari 458 (124.5) in factory trim
Very nice comparison! Thanks for sharing, Dutch regards, Nico.
How about an LFX gm V6 test?I'm sure the junkyards are full of them and they are becoming a popular swap because of how relatively compact they are with manifolds in the heads.Maybe a little boost and see what they are capable of doing and maybe finding some limitations
Great testing, keep up the great work
What were the boost pressures with the GT45 test? I heard 7-8 psi but there were 3 runs shown, thank you!
Please test one of those new electric turbos. I have seen some about them but it was putting out 8psi of boost for less than half the price for a turbo set up.
Those are for tiny engines. Wait for garretts 48 volt e turbo to come out. It's a normal turbo with electric aid to eliminate lag. www.garrettmotion.com/news/media/press-release/garrett-to-launch-industrys-first-electric-turbo/
Basically what they do in f1
@richard Holdener curious as to why 17* timing? Were you seeing knock? And was that at peak tq or were you ramping timing as rpm increased to keep peak hp climbing? Also curious what the back pressure was with using the stock exhaust manifold. I would guess that flow is being hurt at higher rpm and that’s why curve is falling off from the Na pulls.
the drop off didn't happen with the FP turbo, we tried more timing-did not log back pressure
FP turbo results look like a low back pressure with a large cam - as soon as back pressure creeps in on the others it'll drop power off pretty quick - that FP probably had 1:1 emap and imap or close to and lets the big cams eat.
Where's the big bang follow-up?!
Hey Richard great video as always great information fun to watch. I would love to maybe see u do a 3.6 LGX turbo twin turbo build how much boost cam it take. Maybe how much none aspirated power any bolt ons to improve power. Just a idea maybe for the future even a LFX 3.6 be cool idk keep up the great work always enjoy ur videos.
Thanks

Has he done a video about ideal turbo for k24? Say I wanted 450-500hp or maybe 600hp on pump gas for street droving and Hiroshima 800-1200hp on e85 is that possible? What woukd be the best for steady power but also make the most peak? I have a 3582r and I make boost around 3500 and on pump gas and only about 10psi the tires spin in second but I feel it could use a little more in 4th and 5th. Do I just need to set up boost by gear or maybe woukd a differemt turbo be ideal? It's in a mr2 spyder
1200 hp on a turbo k24 takes a lot more than e85
Great video, really appreciate the stepwise repeatable scientific approach that you take here. Regarding that biggest turbo, holding up at the top of the rev range, I believe that most likely relates to how the pressure difference across the engine (between inlet and exhaust) is developing. I'm guessing that biggest turbo still has positive DP in that high rpm range when the others are going to zero or negative. Just one man's opinion :)
If the dyno can do a 5000 rpm run i.e. 3000-8000 rpm, can you start to show v8 engines at 2000 rpm and up? Off the line power is important for heavier vehicles.
the Power Mark is a different dyno (DTS/Superflow hybrid)
Please do a compound turbo on something to show benefits of usable power and see if the small charger actually chokes it out with big power or if it doesnt
please see the compound turbo ls video that is up
Such a great video brother good job man!! Hey so what brand is the 62mm turbo do you have an affiliate link on where to purchase it? I want to do a budget turbo set up on my 1 of 1 kswapped Ford Festiva. If you could share any insight on a full budget build that would be fantastic. I’m new to the k24 but man they seems to make great power and stay fairly reliable even with a stock longblock. Any chance I’d be able to email you for a chat?
THE 62MM WAS ACTUALLY A 67MM AND WAS FROM PRECISION
@ dang that’s a good turbo any recommendations that’s will do the job but not break the bank?
@@richardholdener1727 so that 67mm was it the 6766? Or the 6775? That are decently priced and man from this video that what I want lol
wondering if there are one of these that puts out around 16lbs for a "Polaris RZR Turbo S" side by side, as the big turbos for this machine are 1500 $ +
what is the na power output of that motor
@@richardholdener1727 ATM just under 200bhp at the crank with the std turbo but have no idea on NA. Around 110 as far as I know
Can you do some cam testing under turbo conditions? This would be awesome!!!
I have a Chenweth dunebuggy that I want to repower and I'm thinking either K24 or J32/J35. I'm not looking for a 600hp screamer more along the lines of 300-400hp with plenty of torque. I could modify the frame and mount the engine up front and run 4wd or could put it in the back and run 2wd. It's a future project something I'll be working on next year or the year after so no rush but would love to get some feedback and what you all think? I kind of like the idea of mounting the engine of up front and pulling the drive line from a 4wd Honda Pilot. Need some help on what all I need to make the engine run as far as computer control. I know older engines alright but haven't had a lot of experience when it comes to modern engines. So any assistance would be greatly appreciated.
I would pick the V6-not sure on the ECU swap portion
@@richardholdener1727 Thank you.
I love boost! There’s a 67mm turbo on my hybrid. Yeah...it burns diesel and rubber.
hey Richard could you tell me if trick flow powerport cleveland heads will bolt right to a speedmaster 351 4.123" bore block or if theres machining to do besides drilling heads 4 the water crossover?
have not tried that
@@richardholdener1727 well thanks for the reply man love what u do🎉
also a procharger and rwd intake on a 3800 would make a good Other Guys hint hint
I got a k24a2 with type S oil pump and a PPT bb 6266 turbo. I’m hoping to do 500hp.
that turbo is big enough
I get a jealous feeling in my gut when a Honda Boi gets boosted. My Truth
If you are ever in San Diego and have access to a dyno we can do some sr20det stuff. It’s through a vw bug transmission though.
You tryin to give that Kinzler manifold away? I'd take it off your hands lol
Would absolutely love to get some Kinsler ITBs for my all motor K. Currently still running the Hayward Performance manifold and it does really well but ITBs are just top shelf all motor units lol. Truthfully my ported and port matched RBC made good power in itself. We’ll see what direction my next $$ gets sent to; ITBs are certainly in my future if I stay all motor but I’m also considering dumping the current piston giving me ~13.5:1 static comp and going for around 10:1 then taking the old Sidewinder and GTX3076 off the parts shelf and making something new happen. Decisions decisions lol
P.S. Someone on the east coast come buy my LS car so I can have more free cash to dump in the rice rocket haha
We want a 2jz test
Excellent video, tons of very valuable info, thank you very much sir! 👍
What system did you use to run the fuel/spark on this engine? Oem or other? Thanks
Would love to see a holset hx35/h1c
you need to do this on a ls 5.3 which a lot of your readers have
What's the approximate lifespan of the g45 in a street application? Can you advise on what turbo and how much hp can I add to a mazda L5ve for a sleeper application on a 4000lb vehicle?
WE'VE RUN THE SAME GT45 FOR 10 YEARS NOW ON THE DYNO
@@richardholdener1727 thanks much for your response. I'm doing a project build on a 2010 Hyundai Santa Fe as a sleeper, it's a heavy vehicle, how much hp should I aim for with the l5ve to have that effect?
no idea what an l5ve is
@@richardholdener1727 😂😂 At least you're honest. The L5 is the engine which came with the 09-13 Mazda 6. It's supposedly a strong engine and fits perfectly in the Santa Fe.
I have a question I have a 2012 Chevrolet Silverado single cab with a 4.3 V6 what size turbo can I use with it without having to Gap the Rings or do you suggest another method of increasing horsepower
the turbo size does not determine ring gap
Another awesome video !
Would love to see this test at 35, 50, and 60psi. This would show the power production limits and spool character of each turbo.
60 PSI?
Have Evo’s and Civic’s running 60psi on the street with these larger PTE6870’s and FP Super99. Larger turbos make best power curve above 40psi.
On a cold motor first thing in the morning, do a 1 by 1 swap for ARP L19 head-studs and send it.
Does a twin scroll turbo any good? I think is something we don’t see often in k series budget
needs a twin scroll exhaust too
Is there an video data regarding a turbo sized too small, such as an 6.0 LS with a small 54-56mm single? How drastically does the power output drop due to increasing back pressure?
watch the bbc 454 single turbo with the gt45
@@richardholdener1727 Good call! I'll take a look! **For reference currently putting together a compounded LQ4 XJ8 which is why I'm curious. Should have some data soon so it'll be interesting to see the similarities in response. Compound K series content is going to be fantastic!
Seeing how much power the K24 can make NA is about what i was looking at getting with a turbo just because i got the A4 and finding cams for that thing sucks, makes good torque tbh, around 270hp with 10 psi, should boogie like a booger
Let make a bet! What will give first ? Rod or Piston? That is if the head gasket holds
I hope you make 1000 with this. I just don't think the stock sleeves will hold. Will be tuned in though! Id like to be proved wrong tbh and see it happen
Excellent! Excellent! review!
Watching your channel inspired me to buy 2 3RZ motors. I have spent a week or so trying to wrap my brain around turbos and which one I need but my head is just mush. This motor is going to be a swap in my 1987 Toyota pickup which lacks power with its 22r. Any advice on turbo size for my 2.7L 4 cylinder 3RZ. Thanks
Has anyone ever done an Intech four cam V8 (Lincoln Mark 8, etc.) to find the power capacity of the stock bottom end for the non-forged crank engines and/or an early to late intake comparison on Lincoln Mark 8 engines ? I was wondering how much boost I can reliably run in my Mark 8 engine and if I should switch to the second gen intake.
you can run a lot if the tune is right and you add ring gap
@@richardholdener1727 I suppose that much is a given, what I am wondering is what the crank itself is able to withstand. I have been told the cast crank in my Mark 8 is only good for around 450 HP
Turbo = good. Thanks Richard great video
