One day would love to see twin holsets from the junkyard or ebay clones that are for the cumins . Hy35w. Using the internal wastegates on a 4.8 or 5.3. The 😎👍 You're the best Richard
I love all your videos, i have a 77 f250 with a 351M in it and would love to turbo it and put a bigger crank in it, so i love all these turbo videos about so many different combos, great stuff
that will put a limit on the amount of boost and timing....E85 is safer and will make more torque/horsepower at the same boost level. Which is the whole point of running E85. Also the fact that everyone always wants more and gasoline and wanting more power can be the death of your rods or ring lands.
@@lazylizard6532 If you don’t have access to E85 there are a few great additives to spice up pump gas these days. Torco race fuel concentrate and “Race Gas” concentrate are two I have personally used with good results. I used Race Gas and pump 93 to keep a 12.5:1 85x89 B20Vtec alive on stock sleeves around 460whp @ 13-14psi, and on my 370 CID/PTE 6870 combo in my Fox I can run the same timing values as my E90 tune while using Pump 93 with Torco concentrate added in and make the same power. Only adjustments I have to make are to fueling. So the additives are an affordable option.
@@kennethpowers8995 yeah guess you don’t daily some of these set up when mixing over priced race gas. I can get 93 but no way in hell am I buying t4 or any 100+ octane to drive to work.
@@bbdl7042 depends how you are tuning. Most if not all current standalone ECUs have a Flex Fuel feature and with that plus a content sensor if properly setup you’re ok to run anything from 87 to 93 to E85 and any dilution or mix of the above. ECU will alter tune using tank sensor and engine sensors like knock etc for whatever fuel mix it’s got in the tank. This is why I prefer to tune flex fuel vs straight E85 tunes. (Pump E85 is almost never actually 85%; it varies batch to batch and season to season.)
I have a gen IV 454 with stock heads that I had ported. A mild cam and few bolt ons. Your last video with the budget turbo makes me want to turbo that engine before I remove it and swap a 6.0 into the obs.
I have an LY6 and a Gen 4 rodded LQ4. LQ4 is going in my Camaro with an 80mm S400 T6 and the LY6 will go in my G8 with a NextGen 7875. Good times to come!
The LY6 would be better with the S480. The rectangular port heads move a ton of air and will really tax the turbine of a 78/75. You might still run out of turbine on the LQ4 if you run much boost.
thanks for doing the bigger turbo test on the smaller engines . I have a fairly large turbo I'd like to use on something . I just need to decide what engine to put it on . lol I have a 355 and a 489 . maybe I will buy a smaller one for the 355 .
Would love to see this 480 on a 5.4 4v mod motor, I am looking at going s480 with 96-88 1.3a/r t6 exhaust hsg or maybe slightly smaller exh hsg to aid response. Great vids.. Keep Em coming
I really appreciate the videos you do and the details and information you provide.... now days twin turbo seem to be the new thing i would love to see twins on ls 5.3 vs mod motor 4.6 4v ....yes typical ford vs chevy same turbo whats the outcome thanks again love the videos keep it up
I really would have liked it if you ran same cam intake heads on each of the ls engines to me what you showed was more of a cluster f____ but that being said I really like watching your videos thanks for all the hard work you put into doing these cant wait to see what you come out with next maybe a 5.3 twin turbo s475 how much peak power can you get out of the 5.3
Richard, why did you have a victorR intake on oval port heads? Stock those heads flow 293 at .500, and very little more above that. With that mild camshaft your not going to make much more power. A super Victor might help a bit, in general a bigger camshaft will help more and if you're worried about floating the valves you could always use a set of 1.6 or even 1.5 rockers. Comp has an extreme marine cam with 254 duration and only 575 lift for gen6 engines with 112lsa. That's a really big hydraulic cam.
@@richardholdener1727 you said Victor jr 454r intake. That's a rec port one. They have a 454o intake for ovals. I kinda wonder if you misspoke but I can't tell looking at pics on the dyno.
Thank you for the comparison. I suspected the 454 would probably be the target...now just need to do a couple of revisions and then build a Dart based system for a Bonneville run. :)
Richard lets see some velocity stack test's on the intake side of the (a) charger, I recently had my car on the dyno and picked up 74 rwhp 57 rw ft lbs and 2 psi of boost by simply removing the elbows to the air filter and installing a velocity stack at my centrifugal charger inlet. My charger is a Torqstorm, Chris recommend I try this!!!
Hey Richard, how about putting a turbo on a decent ford 460. I would like to see what a good 460 with decent aluminum heads and all the other good stuff would do.
Its gonna do about what a 454 does. Both engines are well supported in the aftermarket and have great cylinder heads so pick a HP number and it can be done.
I’ve always personally been partial to straight Garrett or PTE units when it comes time to buy a turbo, but these Borg units seem to be very popular and perform quite well. Strange but more than a couple of guys I know that used to run Holsets now run BW turbos. I’m also recently impressed by the China/EBay GT3582R clones- they run very well! We have my brother in law’s budget DSM into the 9’s on one and it’s a $120 turbo haha. Speaking of which, ever plan to dyno test or Big Bang a 4G63? The 93 AWD Talon I threw together with the eBay GT35 for my bro is running the car’s original bone stock 132k mile shortblock, ARP head studs, ported stock head with Kelford cams and gears, JMF intake setup to run an Accufab 75mm TB. This I believe is the current bottleneck of his setup and had I purchased the JMF manifold myself I would have had it configured to run an 80-90mm Q45 style TB but the setup still makes great power. Personal best is 9.63 @ 142 down at Showtime Dragway in Pinellas. Car is factory auto and around 2900lbs so that China turbo is making steam for sure. It’s the GT3582R T3/4 bolt with .70 AR sitting on a Megan “long tube” manifold. It’s only ever been street tuned but as I said traps 142 through an auto at over 3000lb race weight with a driver and E90 in the fuel cell. Would love to see a Big Bang 4G!!
Richard would you be able to try out some other truck cams from other brands? summit racing has a whole line of truck cams that are cheaper than dirt and id love to see how well they would perform compared to the btr cams
Why is 900+ ft/lbs of torque a bad thing for the big block? I have a 496 in my 71 Chevelle that is about to get a turbo/efi make over. So these vids are great for keeping its unassuming internals somewhat safe
I'm sure you know if you want the 454 to Rev... You need lighter valve train,,, lifters, retainer, even rockers, maybe even custom cam... But that great Power from all set ups.... Great Info Richard 💪🏾💪🏾💪🏾💪🏻💪🏻💪🏻
Love the videos very very informative!!! by any chance do you think you would ever do a big bang on the dohc 2.3l from like a 2007 ranger I see them at junkyards all the time out here in Arizona lol
My son decided he wants to autocross instead of drag race now so all of my WOT turbo stuff is going to kind of laggy I think what’s your thoughts? GenIV 5.3ls 243 heads ls6 intake or truck intake 120# injectors comp-229/236 623/617 114 lsa holder hx55 26cm exhaust housing th400 in a 71 Camaro 12pt cage. Should I buy a smaller cam to get the rpm power range down a bit
That cam is a good size but not crazy for a 5.3l. That turbo is huge. A 26cm housing is big...why does he need to autocross with 1000hp? The 26cm housing is about 1.15 Ar and the turbo is about the same size as the s475. I would look at a smaller exhaust housing, 17cm is available. Autocross with a th400, do you have a full manual valve body? What stall speed? The turbo lag will be an issue based on how long it takes to make boost, I think you're having a boost threshold issue. Even if you put a stock or btr truck cam in the engine, it will not appreciably change the boost response. Even the best camshaft for torque will be within 20ft lbs of this one at 4000rpm, you might get a little better off boost response but you might only see this rpm twice in a run. Your son might have to learn to left foot brake to keep the turbo spooled or you can do some antilag in the programming. That turbo is really big for what you're doing.
Hey Richard, Regarding boost response can you do a turbo setup with a ridiculously long Y pipe and boost pipe and compare to a minimalist system. Is there any difference to boost response?
It's almost impossible to test that on an engine dyno. Even a chassis dyno is a challenge. You almost need real world testing, laps at Sebring or ViR or something with logged boost data.
Hey Richard, would running btr stage 2 turbo cam on a 4.8/5.3 still be feasible as a N/A setup for a tad until the truck got boosted? Or would it be better to stick with a NA cam instead.
@@richardholdener1727 thanks for the reply, great sir. After I commented, I just found your video from months ago about every cam being a boost cam... thank you!
In my 51 Ford lq4 street truck am i really going to see a difference in 5 or 600 hp going to 7 or 800 hp? Or is traction just going to not happen either Way?
I had a 53 Merc pickup powered by an 8V-53 blown small block mopar in my youth. Not much traction until I removed a couple of leafs from the rear...then much better. Current ride is a turbo BBC 35 pickup and I have lots of traction...amazing what 40 years of suspension development will do...plus a set of 255/15 ET-Streets.
Honestly on the street its hard to tell the difference between 500whp and 700whp in a RWD vehicle other than being able to knock the tires loose from a higher speed.
You could have chosen a far better cam for the 5.3. It basicly makes the same power as the previous test untill over 5000 rpm. Basically usless on the street without a way better cam.
This is an honest question why run such large turbos that are laggy when making that boost number I deal more with diesels that make more boost with smaller chargers this is just me being curious why not use a smaller turbo
Hey rich I've have had my 4.8 862 heads milled .030 and I never cc'ed the chambers any guess what compression numbers you think that will make and will my gt45 still work at that compression?
@@richardholdener1727 lol, my bad. Compare the compressions. I have heard old timers talk about shaving 40 thousandths off and get better compression and power. I guess it would turn in to a myth busters video... 🤣🤣
@Richard Holdener thanks!! I asked you to run an S480/5.3 and you did! Now that I've seen the results, I can't wait to get mine done and run it! Do you have any further tests at higher boost levels? Do you also test A2A intercooler vs A2W? I'd be interested in that too. Thank Frieburger for me too!
@@richardholdener1727 okay and what would you recommend for around 700 with the t56 tremec manual trans ? Upto say 14psi of boost ? I plan to retain a t4 but struck between a s480 and the s475 and whether a 1.25 or 1.10 ar would be better for my application
What kind of camparison is a long stroke small bore 4.8 with boost to a short stroke larger bore naturally aspirated with 50 year old cylinder head technology? Of course the 4.8 made more power Mr. Obvious.

tim is correct-less concern about cam (though I would go smaller), but definitely better (smaller) turbo choices
Was wondering how camshaft lsa effects a turbocharged setup. Seems most turbo cams are 114 or more. Why is that?
To reduce overlap. You lose the scavenging effect that a performance N/A cam is designed for, due to the higher back pressure in a turbo setup.
