Help, need more boost!
I have an 05 Monaro (Pontiac GTO) with a 402 LQ9, Maggie TVS2300 and 9.5:1 CR.
It's making 13psi with a 2.8 front pulley and overdriven rear pullies. I'm trying to get 18-20psi into it so I think the only option is a larger crank balancer. The largest I can find is the ECS 8" but I'm not sure it is big enough. Is a bigger one available, maybe a 9" that won't foul the water pump? Are there other options to get more boost?
Hope you can help.
