I have 2004 cobra with 2.3l whipple
upper pulley 3"
lower pulley 2lb
Now I need to buy a 4lb lower pulley.
I need to know how much boost I should see with the new combo:
3" upper pulley
4lb lower pulley
????
Finally I received my MMR Street Mod 900SE 4.75 stroker short block
I would like to thanks the mmr team for their great job and also I want to thanks the guy who works in mmr customer service (Greg).
