combo opinions and questions... please help

dragstang86 · 10-13-2002, 01:02 PM

Im planning on making quite a few changes within about a month or so. I wanna know what u guys think and any suggestions would be greatly appreciated.

Right now i have....
306, gt-40p, cobra intake, 70mm throttle body, e303 cam, 1.6 roller rockers, bbk fender well, stock MAF and injectors, 373's, C-4 Tranny with 3500 stall, aluminum driveshaft, and 50ox flywheel, pullies, no AC, no smog pump, shorties, x-pipe, flowmasters

with that combo...shifting at 5000 i went a 13.30 @ 99 leaving from an idle...I think it will go at least a 13.10 with good traction and decent weather..

What im planning on changing...
AFR 58cc 165's or 185's ????, porting the cobra intake upper and lower (can have it done for free), C&L MAF..what injectors???, should i go with 1.7's or a different cam? Electric fan and electric waterpump. Then getting all tuned on the dyno.

How much RWHP do you think i will be making with that combo and what kind of e.t.'s do you think ill see? I hoping for at least low 12's. I would like to get in the high 11's on motor. What would i need to see these e.t's? I have all the suspension work done so thats not an issue.(sub frames, 70/30's, lift bars, etc...)

thanks alot for all your help,

If you have a 3500 stall, why are you leaving from idle?

(maybe I'm misunderstanding). What type of 60 ft times are you pulling? Have you already had your car dynoed? I would've thought you would be shifting closer to 5500 rpm.

Seems that with the future combo you could be hitting high 12s with good traction and driving. Sorry, don't see 11s.

Leaving from idle because of traction problems. Coming up on the convertor with the 10 inch hoosier quick times i was having a 2.15 60ft. When i left from idle i still spun but had a 1.75 60ft. I still only have the limited slip rear so with a posi it should be about a 13.0 or 12.9 on a good day cause i will be able to come up on the convertor. The 13.3 was on a humid day with a strong head wind and leaving from idle. Just goin to an electric fan and electric water pump will pick it up an easy 3 tenths alone. So it should definately be faster than high twelves with new combo. A friend of mine has a 90 gt with stock bottom, dart 2.02 valve heads and systemax intake, 4.10's, c-4 2800 stall, Z cam and went a 11.70 hitting fuel cut off just past the 1000ft mark. So you are saying im only gonna get a few tenths from electric fan, electric water pump,Afr heads, and a ported upper and lower intake, and a C&L MAF, and 24 lb. injectors? I mean if that was all the gain i would see then it definately isn't worth the 2 grand or so im about to spend.
