Ebay GT45 + 5.9 Magnum + E85 blow thru

Good job! What do you normally spin this up to? I see 5350 max rpm. Hows the street maners on 12psi?
When I race I shift around 5500, hit 5800 on occasion. Rev limiter is set at 6000. I keep it super safe. 12psi on the street is too violent. Im not sure what is considered a "fast spool" but around 3000rpm the turbo is already coming on strong.
