Whipple 3.4 Guys Boost ?

[Hilander]

Wondering what pulley ratio to boost you are seeing? Exhaust setup would be good too?

As for me.

4" upper/ 2 pound metco lower = 15psi
3.5" upper/ 2 pound metco lower = 18psi

I run Kooks headers along with high flow cats and Silver Bullet Exhaust.

PS my total boost should be lower because of the thin thin air up here at 1 mile elevation.
