Large Neck on Stock Intercooler

[Doctor Evil]

I have a buddy of mine gave me a perfect stock intercooler with the large Duttweiler neck on it. How much will this help me? I am running consistant 12.00's to 11.90's at 112 mph, with my stock one. I am not expecting too much, but it should be better than I have?????? Thanks

if you are currently running 20 psi of boost, your boost will go up to 21-22 psi with the change. The rise in boost will be worth a couple .1's. If you turn the boost back down, expect about a mph increase.
