GTP Build. Sub 13 Second 300whp goals!

If you plan to stay as close to or under 300whp, 42.5# injectors will do you just fine.
If you plan on making 300whp or more, I would recommend 65# so you can safely flow E85. You'll appreciate the power difference between fuels.
I have 80#er's, and a Racetronix fuel pump rewire harness on my stock 87k mile pump.

I'm not running E85. Just gas. I don't know what power I'll make, that's just a goal. The sub 13 seconds is more important.
