Selecting a turbo for a fast spool 421ci 1000whp What is available for something that spools pretty fast on a 421ci 8.5:1 compression engine? Around 1000whp max. And in a small package.
Something on the lower end of the price scale also.
I see S400's are priced pretty decent. They make a ton of different ones though, S400-78, S400-82 ETT, and a bunch more. Which would spool fast and put me where I want?
Or what other turbos are out there in that price range?
Im not opposed to a used one either.
Thanks.

I was looking on your website, Do you know the outside dimensions of that GT91? And also I was looking at the S400-80ETT w/ a 96mm turbine wheel.....how would that be? which one would be dimension wise smaller in outside diameter?

GT91 is smaller then a S400 based turbo. The GT91 is 10"L X 9"WX8.5" T

For the 421, and wanting only 1000whp, would the 1.08 A/R be best? What would spool characteristics be like? Guestimate on what RPM to be fully spooled? 3500 would be ideal.
Why would a GT91 be almost too small? According to the list and by HP ratings a smaller one would work.
