i have twisted wedge heads and gt40 intake with tfs stage 1 cam, 65 mm throttle body and spacer, and 76mm maf, so which ones should i use for better hp and performance. next year going to have heads and intake ported and polished.
Is this on a stock short block? Or a stroker? What size heads do you have ?
I would probably use 30's and calibrate the mass air accordingly, that way you if you choose to run nitrous or change to a stroker you wont have to buy injectors again.
Go with the 30's and matching MAFM. You may also want to get a larger throttle body and egr spacer to take advantage of the entire combo.The TFS stage 2 cam probably wouldnt be a bad idea either. Also, if you dont have an adjustable FPR, get one, along with a fp gauge.
Last year i was running 30lb. injectors with a stock 302 and trick flow t.w. heads out of the box. And the car ran fine. Now i had my heads ported and i didn't have to change my injectors. I would deffinatly go with the 30's
i was thinking about upgrading my throttle body and spacer to a 75 mm and get a 80 mm maf cal for 30 lb, and i do have a FPR from Kirban. 30's is a wise decision, just so i don't have to buy new ones
