On my 408 in my car Dr. Turbo recommended the gt91 with the 94 turbine on a t6 with a .96ar housing. It spools really well at 12psi. I am on about 9.5:1 compression with l92 heads.

I have PRC L92 heads,spools really well at 12psi ? What do you mean,you can launch at 12 psi ? Would you think a 1.08 a.r sounds to high ?Im wanting to build this as fast as possible on the street,i have a low 9 second street car that works very well to outrun lol.
I run the car at 12psi currently. I havent really launched the car but can get a couple of psi on the 2 step. The 1.08 might do good with the higher compression in your motor. I know the .96 does great for me.

Id rather see you in a full GT55 sized turbine at 112mm.
What exactly do you mean,im new to this turbo language.What is a full GT55 ? And the turbine itself is 112mm ?
Nitrous is alot easier LOL

Talk to dudeman.. he switched from a gt91 to an S500 that has the same wheel dimensions as the gT5518..
Hes a stock shortblock 6.0.... and your a 402 with damn near 11:1 compression on E85......
You are gonna need the 112mm turbine... trust me on that.
I hit 12 psi by 4000 or so. I am sure I could gain more with a bigger turbine, but in a street car I think I would lose spool time with a 112. Has there been a side by side comparison with this John? Does the billet wheel gt 55 help prevent this? Just curious.

At the very least... id be looking at the GT5088 instead of the GT91... its got a 104mm turbine iirc.
We havent really done any back to backing with different sized turbines. Since Ive became involved in what Joses doing at FI all hes done is proof of concept dynos on all the new compressor wheels hes been bringing to market.
The billet wheels help im sure. On the new Billet 80 for the S400... that wheel is 50 grams lighter than the cast wheel... pretty drastic difference.

Actually made 35 more rear wheel horsepower than the uber expensive garrett GTX5533 it was back to backed against. The only down side is that it was 150 rpm behind on the boost curve. Thing is.. without instrumentation like a datalogger or dyno... i doubt anybodys assometer could ever tell the difference.
1-2 grand cheaper and makes more power... Pretty damn good i think.
The new 94mm ETR 11 blade comp wheel in a GT55 put 1248 to the tire last week at 20 psi. Engine was a 390ci AES built LS.

Thanks for the reply John. I will have to look at the bigger turbine when I want to step up and make more power. The only thing I was worried about was spool time, but you cleared that up. When I outgrow the 91, I will get with you. Thanks again.
Our new ETR 88, 91 will be available soon. John will be testing them on some setups also.
liljohn I can not believe the difference from one cam to the next on how fast the turbo comes to life on my lil 5.3.
