Hello I'm building a crvtec turbo and I want to achieve somewhere near 500 hp. This will be a street driven car. I have it narrowed down to two turbo's

with the stage 5 wheel and

What will the spool up time be with both of them, and will they offer similar gains. thanx

 

spool is going to depend on alot of things, compression/cams/manifold design, wastegate etc. So I am sure their is nobody that could tell you at what rpm you will spool at exactly.. My guess is that with the 60-1 t4 you are looking to get full boost at around 6000rpms and up, that is my guess.
