LB7 Turbo Kits, and the LB7 Cheetah

[Brayden]

That sounds like a pain..

Our turbo is a completely new S300 cartridge based turbo. Only IHI parts are the compressor cover and the turbine housing. We have the technology to make them cost effective. 2100.00 is a decent price for a drop in turbo with the ability to make 650hp. The next versions will be able to support higher power levels.

If you're going to pull an IHI turbo you may as well put something better than a compressor wheel in it. Kudo's for your creativity, and accomplishment, but you are right, what you did isn't worth the time, money, for small gains.

This turbo, our 63/68 Borg in T4 trim has made over 650hp already with a billet wheel.

For anybody wanting controllable boost pressures (Wastegate=No Headstuds Necessary) and the ability to make 650hp for under 2100.00 this is the turbo you need.

(Just be careful with the LB7 internals....they really dont like 580+)

My LLY internals sure don't seem to mind 700hp :hug:

Hell yeah. Congrats on the tune up john. Looking toward to lining up with ya at edgewater next spring. Maybe ill have my tranny built by then

Come on Tom.. You didn't dyno an LB7 with a lift pump and tune on a stock turbo at 580rwhp ..

You might have had an LBZ pump, injectors and turbo mouthpiece, downpipe, manifolds and uppipes to go along with that.. Don't muddy up a thread with Apples to Kumkwats comparisons.

he dynoed the 580 2 years ago, he only had a tune, intake, exhaust, modded intake horn , modded reg & lift pump back then

 

[Brayden]

So what did it dyno with just a tune only before the mod'd reg, etc etc.. Tune only, intake and exhaust?

Because a mod'd reg is worth maybe 10hp, and the intake horn another 10hp.

So it rolled 550+hp with a tune?

Those are not typical results for tune only trucks. The accepted standard is 500/1000 for a tune only LB7/LLY. Some tweaks here and there may yield higher numbers but most all dyno's are going to land them around 500hp +/-.

Is Heybob's truck still running the original stock CP3? Cause I know it's tired from having to cut the pulsewidth back on the stock charger tune.

 

[carpenca]

Yes it is still his stock CP3...

If you guys want to play that game...this truck dyno'd 473/860 with the stock turbo and downpipe.

 

[adrenaholc1]

Hey John, just curious what dyno (where) you were on?

Will this new charger move more air than a s366/74 .91ar? Are they billet wheels? How snappy is spoolup compared to a stock ihi? Btw, I used a new exh wheel and compressor wheel when I built the hybrid ihi.

same dyno for both runs & no other changes other than the turbo?

 

[jheyob]

Nope, but he didn't do 580 on this dyno with a stock charger and stock fueling so I figured why bother comparing apples to apples if he's not.

 

[Noreaster]

& not like he would roll 690 with that turbo either

Thanks for having my back, AJ. Braydon, sorry to muddy up your thread, but just ask your friends Mark and Matt....yes I did. More than once, too.

Stock LB7
Stock LB7 fuel system with modded LB7 reg.
Stock LB7 turbo with modded OEM horn and boost valve (I assume you mod the horns on these Cheetahs, correct?)
Exhaust, intake, lift pump, tune...the basics.

NO uppipes, manifolds, injectors, LBZ CP3 or downpipe. Apples to apples.

Truck ran 12.28 and 12.29 at roughly 6500lbs at a track Im not comfortable racing at nor are they real "friendly" to diesels in the first place.
So sub the modded reg, thats still 570. Track runs peg at ~555.

Sorry you dont think anyone other than a "shop" can legitimately put a truck together. I chronicled everything on this site as I went along, so there are no "secrets" to what I did.

Good luck with your turbo. I hope it works well and is a good seller for you.

Its no fair comparing Tom's truck to many other LB7's IMO. What his stock LB7 did is simply not the norm, IMO.



Back on topic though, safe to assume these are going to handle more than 35psi okay, right since they have different guts? Seems interesting.

They'll handle whatever your head bolts will Just built the 66/73 turbine version tonight. Should have results soon.

Any updates?

Any updates?

^^ Second that?

Had we done the loading exactly like it was at the DC dyno I wouldn't doubt the numbers would have been identical, but this sheet is from the dyno it baselined on, updated to std correction. 488 run was stock turbo. Rail fell down to 21k in the recent runs.
