so what were saying is that a s400 will be fine. My motor will make well over 400 rwhp N/A. I don't think spool time will be a problem. If it starts coming on hard at 3000-3500 I don't see a problem with it.
Were can I find a s400 for sale?

1.32 ar with only a 74mm compressor sounds like the wrong turbo to me why not spend another 400 dollars and out spool your competitor by about 2000 rpms. The compressor is a tad smaller also which means it might be a tad down on power compared to a TC76.Then he can leave his competitor in the dust who thinks his s400 is the ****. Face it.

were talking 346 cubes here for street use. 1.32 ar I think is way too big and would take too long to spool kinda like a centrifical blower would. I hit peak boost right about 3000 rpms maybe a bit before. It will start spooling at 1800 rpms. Feels like a twin screw on steroids. Isn't the s400 a t6 exhaust housing? Maybe if he was planning on going 408 down the road.

S400's can be had with smaller exhaust housings now, 1.01 and even a T4 .96 is available from what I understand. The borg units are pretty beefy internally when shipped from BW.
They are physically huge though....tough to place in a tight compartment...but it can be done.

I am in the middle of redesigning my hot parts to fit a wider range of turbos. I am gonna run the ST80 on my new shop car (99 Z28).
The TC76MPS is a kick as unit. Spools fast, makes the power, and is easy to package.
