i say a 70mm JUST incase you wanna bump it up to 12 psi

 

not to hijack but im planning a smiliar setup and i figured out roughly 50lb/min and 1.5PR and that seems a little on the low side of the map, but thats only figuring 8psi. But looks like it would make right at 500hp.

 

Isn't MGMC running like 580 at the wheels with his PT67?

 

I always like to size a turbo so it's just starting to run off the chart at it's peak, so it's running though the middle of the map most of the time. Why would you want it most efficient only at peak and not where your gonna be most of the time?

 

a friend of mine has a bunch of various turbos off various different vehicles. is there any vehicle you can think of that might have a turbo that would work for me?

 

Any diesels?

 

yeah he has some from a few ford diesels and probably others that he could get a hold of

 

Hey guys I'm back again. My goals have changed slightly, still looking for very quick spoolup but now I'm shooting for 5-6 psi. Would you guys still recommend the t70 and the t67 or is there something else out there I could run?
