Guys go mid 12s on GT40P heads all the time. Aluminum heads aren't required for that kind of speed unless your car weighs a ton.
If you had Aluminum heads on the car you'd be in the 12.7's those other guys are hitting. Since you're so close take out the passenger seat, run with 1/8 tank of high octane fuel, try to put a little more timing in it. You should be able to get a 12.99 with this alone I would think.

He's not one of them. Aluminum heads a bit more power and weight savings would have put him close to 12.7's easy. Obviously he's beyond this so again, weight savings, more timing, maybe more fuel and hard launches will get the elusive number I'm sure. He's also running in high humidity and temp.
Maybe if I had taken out the passenger seat and didnt eat that hot dog earlier. Really at 13.06 any little tiny thing could have nudged me over. But I dont think fuel is my issue I've got 255lph pump, bumped the fp a little, and injectors are stock but I dont think with my hp levels I would benefit from bigger injectors, and my timing is around 14 or 15*. I'd be willing to try bigger injectors but I'm not gonna go out and buy em.
haha yea I'll tape all the cracks in between my hood and doors too.Take that change out of the ashtray and vacuum the rug, all that counts.Oh and who can forget, wax the car, it will be more aero. You're gonna have to find a trick to get that .07 off.
then why is it not getting there! Something is happening after the 1/8 mile, its not pulling in 4th gear. I also accidentally dropped my tire pressure down to 11psi, and I didn't have change to fill it up a little, I wanted to run it around 14psi. I felt my car swaying a little at the end of the track, nothing dangerous but could something like tire pressure effect me at the other end? Or am I just over thinking this.8.3= 12.9 so your about on par with where it should be based on the 1/8 mile...
Its a suggestion.Just because they do it doesn't mean it right or the best way to get it down the track
Also put like 35 to 40 psi in the front tires less rolling resistance...also maybe the car is leaning out on top end?...I know my car was on top end and my 1/8 was the same as yours,...my mph was a little higher but same time...Just a suggestion...
So what more fuel? Bigger injectors? I pulled my plugs I'll take a pic of em.
