I just looked at the T/S times that people are running and want to know what the deal is? I am right now running 13.90@98 mph. That computes to 246 hp give or take at the rear tires now i haven't swapped to the
GT-40P heads,or GT-40 intake yet but I am figuring on producing around 333 hp at the tires when i am done which is only good for 12.50's I know for a fact that off the shelf GT-40p's flow 196 cfm per runner which is only good for 403 hp at the flywheel. take into account 15% drivetrain loss and pow you are stuck with 340 hp so may i ask who is porting their heads and intake to get a little 25 hp boost? if i am wrong i don't beleive you can port your heads and intake.
please enlighten me.
