    This is on a gen 1 whipple 2.3 with stock long block . Right now the car has 19psi peak per dyno sheet with stock lower and rr 2.9 upper and stock tb and ex manifolds. Gonna be installing Arh 1 3/4 long tubes and a sb/tb along with sb inlet change. Looking to regain any psi loss and run 19-20 psi (torco tune). I have a few pulley options with having a metco 2 and 4 lb ring along with the 2.9 now on i have a 3.25 upper. I figure I can run the 2.9/2lb combo or the 3.25/4lb combo. Leaning towards 2.9/2lb I rather not have to switch the alt pulley. Does this This sound about close??.
