Ok guys here I am down to the wire on my modifications and I need some opinions from the group ....

My 2007 requires a Lower pulley change to a 2008 lower or later because of the mass of the orig one...... That gives me three options ..(1) I can go with a standard 2008 as a change or (2) go with a Inovators West 10% lower. Now here's what....
I've got a new VMP with a 2.4 upper on the car ( Thanks BJ and Justin )along with all the fuel support I'll need ( 72's and a KB BAP ) Per graphs from VMP a 2.4 upper with stock lower will produce about 18 psi boost. The same 2.4 with a 10% lower will produce about 20 - 21 psi. I can ,as an option (3), put on the 10% lower and use a 2.6 VMP upper and get the same 18 psi with room to move up with the 2.4 if I want to but I'm kind of leaning toward the stock lower as 21psi sounds like a ton of boost to me. The car still needs to be street friendly. PS: I AM also looking at a single pc drive shaft.

Chime in here guys and let me hear from your experience facing the same situation where you went with it and your RWHP and Torque

Thanks

I would go with the 10% OD IW balancer with the 2.4 upper, 3psi more for a total of 21 isnt going to make or break your combo either way.
