Well I wouldn't go off what automach says, I think his claims are grandiose lol. I might have mislead a little, when I ran 13.1 at 107 it had gears exhaust stock weight and a bad tune. Also my exhaust is anything but efficient (it does a u-turn in the muffler for side exhaust) When I added the 85mm maf and intake I had to add 20% fuel at wot, and I don't know if the intake and maf was enough to gain 3 to 5 mph. I know my car won't see 11's without nitrous. I don't feel the 4.6 responds to bolt ons as well as the LSX but with that said we are talking about a motor almost 2ltrs smaller. I think it will take a bolt on Mach to hang with a stock GTO and a race car to hang with a bolt on GTO.
