Can't Decide......
 

What would be a better setup, I'm looking to make 700whp through an Unlocked th400 and 5000 stal in a 365.

Twin 60-1's or if i was to go with a large single i was thinkin gof the MP gt45-76 or a airwerks s74, anyone have any experiance with either of the two large turbo's or have a compressor map or CFM rating.

Using Engine Analyzer Pro 3.3 Full version, the simulation is showing almost the same hp and tq at 15 and 20 psi for both setups, on;y change is the s74 is spooling about 325rpm later..... any input?

Back presuure on the twins was 22.5 psi, on the single it was 31psi.
