Thats right, the LB7 Cheetah is back, new improved and better than ever. Its currently being tested in a 63mm format, that will fit both the 2.5" work stock rules, and most stock appearing turbo rules. The LB7 Cheetah, in true Cheetah form will retain the stock compressor and turbine housing, as well as the OEM wastegate function. There is also headway being made on a electronically controlled wastegate that will integrate with your EFI Live tuning. With the wastegate, this charger will allow LB7s to make fun reliable horsepower without jeopordizing the headgaskets. We should start getting numbers back from the test truck in the coming weeks. The 63mm LB7 Cheetah is going to start out at $2147.50.

FPE also offers complete S300 T4 turbo kits, that come complete with all the nescessary components you need to convert your LB7 to a T4 pedestal based turbo. Our entry level S363/68 LB7 setup, which will support 600-625RWHP while keeping EGTs well within check, can be bought for around $3062. They are built with non-wastegated housings and are capable of making 40+ PSI of boost, so headstuds are recomended. For the 600RWHP guys this charger is an absolute blast to drive on the street, whether its just daily driving or being worked as a tow rig. It has been described as feeling electric, due to its extremely quick spool up and response. All the while the EGTs never break over 1400*

Give us a call at the shop if there are any other questions. 765.676.5063

are the cheetahs built from a new turbo or from a used one?

The Cart is new! The only OEM parts are the turbine housing and the compressor housing.

are you doing a core on the housings?

I wouldnt count on seeing it on the website any time soon, its kind of out dated and a sadly a poor way to search for FPE product or information. Once we move into a bigger facility, a better website will become a top priority. If you have questions or would just like to see some pictures of product, feel free to call me or send me a PM and I will hook you up.

Yes there will be a core charge for the stock turbo, when you purchase the LB7 Cheetah.

The test truck is getting on the dyno this afternoon, so we should have some numbers to share for the 63mm LB7 Cheetah. :D

Does this Cheetah for LBZ replacing stock turbo on an 06' truck have ball bearings with oil and water cooling, in other way of asking the most durable turbo Garrett makes as to wanting that for the performance of this Cheetah wheel. Next is it titanuim wheel or what? These sure have good reviews from buyers who changed to them after the truck was tuned for the injectors air etc. it had too a correct job in other words. Thanks if you have time to answer on this.

No, it is S300 based from Caleb's description and pictures.

Done that on a completely stock charger. You'll have to do better than that to justify $2100.
What was the tuning setup? Higher than 3100us pulse/28* timing? What other mods done to the engine/truck?
What is max safe boost compared to stock charger, everything else being equal?

Not on this dyno :thumb: LLY w/trans, lift pump and tuning did 507/967 on it. I'd have to look at the tunes but either 3000 or 3200 pulse and 30* timing. Other mods are listed in sig.

Have you ran your truck at the track since you put down your 585/1042?

No it hasn't, was dyno'd 4 hours ago. Those are stock turbo times.

True about the dyno, but my numbers were backed up at the track. I hope yours are too. (Just be careful with the LB7 internals....they really dont like 580+)

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.

Still the stock exhaust wheel? I tried a 64mm b/w wheel with a garrett exhaust wheel in the lb7 stock cartridge, with machined housings. It is just too much expense to dump into stock chargers. People just don't understand what's involved in parts and machining. Imop, I wouldn't waste time with it. I would move on to better chargers.

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.

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

Brayden
11-17-2011, 07:54 AM
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 +/-.

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.

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
11-17-2011, 03:23 PM
& 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.

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.

Not sure how old the thread was but I saw on Diesel Place a guy had a 71.5MM cheetah on his LB7. Brayden or Caleb, are these still available or "buildable" for us LB7 guys? Only saw the 63 avaialble on your website.

I believe that was when they used garrett parts, now using borg warner so Ill guess that the 71.5 in an IHI frame is a no
