20 psi!
I thought his goal was close to 600...? We have guys hitting 600 around 12psi. I hit 533 at 10lbs.
What does he plan to do about his MAF situation? Does he have the GTM ones?
Im going with 11:1 compression with Arias pistons tuning off E85 to reduce spool time. I plan to set it around 15 psi and plan to easily break 600. I would go up to 17 or so but I will max out my 3" intake tubes at 15.
