Absolutely agree. I have my 89 firebird with it and think it would make good truck motor with all of that low end torque. Wood love to have an old Z71 with 4x4 and tpi.

number1 is the zr1

I think it's awesome I changed my tpi to stealth ram I miss my low end torque but love being able to pull to 6k

Unmatched torque.

@@backyardbuck6362 GM should have made the an l98 engine option in the in the trucks

Me too. It looks very high performance.

I still love looking at my TPI L98 when I open my hood. It's still badass looking today

Could it tow?

@@xmo552 It will if you don't mind replacing clutch discs and refacing your flywheel every few hundred miles. Towing is all about having the right cam. A cam that likes to rev over 5K is not that, no matter what induction system. I know because I towed with my TPI that has an XFI cam with 216/223 dur and destroyed my clutch in the process.

@@twinsemi I'd go automatic on this truck.

Had one for my highscool ride in the early '00s, modded right they're streetlight assassins LoL made alot of lunch monies against the fastless & furious crowds

I went to a junkyard and bought a rear end. At the time i didnt know about the aussie 9 bolt. Thats what i ended up buyin.....

OH YEA? My cousin in West Tennessee bought/ordered a brand spank new 1989 TURBO TRANS AM 20TH ANNIVERSARY INDY PACE. Had our own 1/4 mile spray paint lined across an old 2 lane road between the cotton fields rite outside of town. So we SMOKED EM ALL PRETTY MUCH back then[stangs, vettes, u name it!! LOL!

I have a 5.7 85 vette any info on how I can start a turbo build?

I have a dyno test that says those siamesed TPI runners do produce more power ........

@@niagrasprings I believe it. But making your own doesn't always go well. Especially when you're inexperienced with welding aluminum.

@@idriwzrd My male parent never taught me anything about working on cars, because he did not know anything. I had to pick it up myself, any way that I could. One of my first major successes, at age 16, was switching the two barrel manifold and carburetor on my 1969 Nova to a quadrajet set up. It was a major undertaking for a 16 year old with no substantial support, and something that my male parent was counting on me NOT to be able to do, because he wanted my car to be slow. Then there is all of the stuff that I messed up --like the horrible paint job that I put on the same car, because I just did not know much about paint, which I still can NOT do, and avoid because its so toxic. I became a machinist, a mechanic, and a welder, mostly so I could know how to work on cars ......now there is a huge electronic aspect to it too. How far along in welding aluminum were you when the attempt was made on the TPI runner tubes?

Yeah trying to turbo the TPi in my corvette is not going to be easy.

Look up beckers garage 😉

Chevy swaps have always been the shit. From carbed SBC's to TPI's to Gen 2 LT1's to LS... Cheapest, easiest and most reliable way to go fast. I'm just waiting on Gen V prices to drop...

@@jaydubb71 my FIL 's Ford Deuce coupe had a 1955 Chevy V8 in it......so as soon as there was a Chevy V8, one was put in that Ford car.

So we're funky paint jobs.

So was mountains of cocaine

Just the fact that you said “he shit” tells me you are 90s

They make great truck motors with all of that torque.

I've said for years the TBI should have been the hp application and the trucks should have had the TPI. I've done plenty of street cars and trucks with TPI with a mild cam, portmatch, and tight headers for good fuel economy and torque. great for towing. did one 383 that had almost 600 ft lbs.

I would love to see more information on tpi versus tbi? Because these tune port injection engines, made great torque down low. Surprise you didn't see these intakes in more truck applications.

People didn’t care so much about modding their trucks back then plus they were needed for work. Whatever came from the factory was generally good enough. Very few “fools” were building their new truck in those days.

lots of truck guys running that intake-works well

Go look up "how long until it grenades" on The Turbo Forums. Bring a drink and a snack you'll be there for a while in awe of what a TPI can do when you wring every last solitary half ounce of power from it.

@@richardholdener1727 Have you got any experience or knowledge on draw thru turbo stuff possibly on a SBC? I know GM and Ford experimented with this shortly in the late 70s and early 80s... as well as aftermarket RV kits. Currently I know the aircooled VW guys use that tech successfully. I'm kind of wondering if low psi boost could help me.

@@richardholdener1727 You tuned most of these with a Holley XFI, correct ?

Is it possible that you meant 'Shirt' ???....

@@uncletevan oops!!!🤣 thanks for catching that!

Mine too

there is more coming this afternoon-brunch!!

@@richardholdener1727 , Love your engine videos, they are top notch, especially the intake manifold comparisons. NASA quality testing. 👍 😎 Were you writing articles and racing Mustangs back in the mid 90 to late 90's ? Your name looks familiar from Super Ford, Hot Rod and Muscle Mustangs & Fast Fords magazines. I made a mistake and sold my 1990 5.0 Mustang back in 1998. 😭😢😲

I have a big one!!! Came off a 12.1 liter diesel, military equipment

You just need to learn how to read a compressor map. Reading a turbine map helps too. Any displacement engine at a given volumetric efficiency at a specific rpm will use a specific amount of air per psi. Now weather you measure total air in cfm (like Garrett) or in kg/min (like Mitsubishi) changes your calculations. A good baisic rule of thumb for me is turbo on engine a spools x psi at x rpm. Engine B displacement multiply by given rpm. Take total and divide by engine B displacement equals engine B spool rpm roughly (different engine shave diffent VE). As long as you don't choke the engine with the compressor or turbine this works pretty well.

We will!

lots of guys running these in trucks

Same, WE NEED HOLDNER MERCHANDISE

Same, we need holdener merch

i think this is the sleeper motor. Minor tweaks to the 90's LT1 , drop it into an early c4 (L98) But then an LS2/3 would be a nice drop in but you can grab a full trans , motor and loom for so cheap for an LT1.

that was only ever in corvettes and camaros... trucks had tbi

Just magazines, and maybe a cable tv show.

@@fryloc359 and books.

Hot rod magazine and motortrand had alot of things going on before youtube

I second the motion I'd love to see an early 5a head 307 with the vin9 HO cam .440 196/210@50 109lsa or something bigger like the comp OL-xe250H-10 run on the dyno you've shown the ford and chevy 5L some love dont leave us Olds guys out in the cold

THAT IS FROM BACK IN THE DAY

@@richardholdener1727 yes it is. Remember it well!!

@@redtesta Are you still doing ford 302 5.0 stuff?

@@xmo552 i haven't after working at mustang dynamics, back in the day and a few years later i got into corvettes after getting completely destroyed all around by one at the track LOL. I actually wanted to get (hold onto your hats) a 95/96 Mustang SVO and fully update it. That car had all the suspension and brakes the GT didn't and the GT had the motor the SVO didn't LOL. I was disappointed with the 4th gen mustangs (had a 1995 convert almost sold that thing within months with is detuned and monstrous 215hp barely 5hp more than my amazing 1985 GT 10 years prior). Last stang i had was a 1999 with the 265hp, just did some gears , pulley and exhaust (the status quo back in the day before all the options now) . I did have it along side my vettes at the time but sold it. I will always have a place in my heart for Ford especially during the 80's :) Rich, did you run the silver state back then? I m trying to remember one day you were in with the black hatch and prepping it and i could have sworn it was for silver state?)

@@redtesta Those years are nice. I have a mark 8 and I'm building a 56 f100 with another Mark 8 donor.

Thats what newer cars do

agree

@@richardholdener1727 Start with low timing Adjust the air fuel. Same for everything, correct ?

Larry Temen where are you from? Lol. My turbo TPI car was in GM High Tech magazine. And runs mid 10’s

we have one of those too

You're still too big. You need like an HX40 or a small turbine TP38 or a 60-1. On a 4.6L or 5.0 Ford they're good for about 425 to the tire and that would be on a stone stock 350.

One thing you can do here is to use a huge turbo like this but run a full stock engine with regular fuel. When your turbo is way oversize and consequently you'll be running very low boost pressure for the airflow, it's much less stress on the engine due to reduced heat load and you'll also be easier on your entire power train due to peak torque coming in at higher rpm and in a smoother manner.

the rising boost curves artificially forces the peak power past the effective rpm of the cam or reflected wave of the intake runner length (the rpm where the combo would make peak power in na form or turbo form with a constant boost curve)

I have TPI intake shoot out coming

Richard Holdener have you ever seen an accel intake that looks like the factory one? I bought an l98 for the long block and haven’t had much luck researching it. One guy said maybe it’s from a lingenfelter

@@gregblau8082 The Accel looks a lot like a crossram.

@@richardholdener1727 Do you have a miniram to test? I've had one since '95!!

@@richardholdener1727 please do the FIRST tpi set up too.

the TPI has tons of top end ......compared to a flat head.

Where are you

that is a lot of cam for a tpi motor

That’s easy. People are always gonna work with what others say is the better engine, l98 tpi needs to breath, first start with creating the best breathing for the engine.

I have a TPI vs Dual Plane test coming up

Take a long non ferrous ball grinder thingy and open up the plenum lower until a 3/4" socket goes through each runner.

He has a video with a 305 TPI, Stealth Ram and Torque Storm blower.

Just talked to Jimmy, he confirmed this was the first prototype car they built

VERY COOL-DID YOU HAVE A QUESTION-JIMMY IS GOOD PEOPLE

@@richardholdener1727 having problems with the fuel system, injectors, and pump need replaced if you want I could send you pictures of how it sets currently, so awesome to see the history of this car
