s400 76mm turbo
#21
Guys keep in mind that Fratena Used a Precision GT45 Based Billet 76mm with a T4 flange on his 8.50's NMCA Street Radial car. His turbo is for sale over on Yellow Bullet right now. His compression was higher than most N/A engine being built on LS1Tech. Its gonna be all about getting the turbo to work from the starting line to the end of the track.
This class is gonna be hard on Boosted application's no matter how you cut it. Small cube engine's with a **** load of compression and Boost at Big RPM's. Gonna be a wild class for sure.

Clifton, Pumpkinhead, did his dynoing up at SQR in Fort Worth, I think that car made mid 700's to the wheels. It ran well for what it was.
I think if anyone is going to get serious with this class, a custom Garrett is going to make more power. I have one that is T6 based, with 408ci. So far, with 12psi, its made 720 on a light tune, at 6000rpm. I wish I had a smaller CI motor, this turbo would make some awesome power.

Less cubes is more power with same turbo?
Hi turbo'd stang,
Are you saying a turbo will support more power or HP on a smaller CID engine? For example you have a stroker 408, so my 364 CID stock cube LQ4 will make more power or boost with this same turbo (assuming both engines have a good cam and heads)? How does that happen? Just curious. Would'nt the 408 be faster with this same S400 76 mm T6 turbo in the same car?

yes, this was all at 14psi. i was leaving at 3k with about 3psi on the brake! this turbo has alot of potential. this is with a lt1, with ported stock heads and a bone stock intake. bout to push it hard with race gas, ported afr's, and alot more boost! we shall see!

Wow great performance on the S400
Hi 4SFEDZ,
Wow could you imagine leaving at 10 -12 lbs of boost on the brake or even say 17 lbs and doing a full run at 17lbs or even 22 lbs? If you can somehow make her hook. How much does your car weigh? My 74 camaro should weigh about 3400 or 3500 lbs with my 200lbs race weight in it when I am done.
Sounds like with a bit of tuning, launch control, 2 step etc you will be in the 5"s in the 1/8th. This is smokin fast in my book on a $600.00 turbo! Was this the base S400 76mm with the T6 1.32 AR exhaust housing? Gives me hope cause my motor will be the stock LQ4 364 cubes. Once I learn how to tune it and drive it pushing the stock short block I will pull the motor and throw forged h beam rods and pistons in there. Probably home port the 317's and crank up the boost and see if I can push her into the mid 5's in the 1/8th. (Hey guys in this economy I am on a super budget, got to push as many stock parts as fast as I can. Cant afford expensive heads in the near future).
I have seen this turbo push cars into the 5's in the 1/8th and 8's in the quarter. For the money there is no better bang for the buck unless you go twin HX turbos from a junk yard and really know what your doing with them. I personally dont know the HX series of turbos but if you know what your doing you can get some HX twins really cheap and push over 1000 flywheel hp.

Its 75 mm
Hi Hank Peabody,
Yes I stand corrected. The borg warner S400 can be ordered wth a 75mm (S475) or an 80mm (S480). you can even order different exhuast housing AR's and T6 or T4. You can also order a 72 or 68 mm compressor to make it a smaller turbo. It's very flexible. And I just found out it can be ordered with a race cover. For example see bullseye power S400 turbo chargers.
