wow thats actually pretty low. peak boost with the stage 1 Cobb on the STI is 17.5 psi... i guess that straight 6 engine allows you to make more power with lower boost pressures. |
335's run 8psi stock and the rule of thumb on this engine is 12 whp for each psi. So 15 psi( 7 psi increase) would be 84whp over stock. Pretty big difference!
A lo of people run 19 psi on their 335s with meth!
