hello, im getting my setup finished, but i have question about the wastegate spring.
am i going to be able to run a stock map sensor with a 0.7 bar spring?

b16a stock internal
60-1 turbo
log manifold
2.5 piping
rc 750s
walbro fuel pump
precision 600hp intercooler
goal is 10 psi and about 280whp

help me out plz.

 

7 x 1.47 = 10.29, theorecitally yes, but if you want your boost cut to work and work properly, be done with it and go with a 3 bar that way you dont have to change as much in the future.
