My sig has my mods. Ive got a gt-40 mildly ported now, but am looking to get into the 12's and make good dyno #'s .

tmoss said:That lower needs more than a gasket match to keep up with the AFR heads, but it is an excellent intake for that application - as is a Performer that has been ported. Loose the spacer if you can.

At 5500rpm the RPM11 is 6hp stronger than the standard performer RPM.
At 6000rpm the RPM11 is 17hp stronger than the standard performer RPM.
With your combo your either knocking on 400hp's door - the RPM11 get you in!
I would guess 420-430 hp with your combo.
Good luck! I seriously would consider no other!
Grunter said:Hey 87GT 306 - From what you are saying if you added this intake (17hp) to 405 - you're right in there at 422hp! I agree on the looks of the GT40 it's an alltime favorite of many - plus it's FORD! But for performance reasons I'm selling my Cobra to get a RPM11 - this should get me in the twelves!
