Hey guys. My car is now running good, most of the bugs are out. Anyway, I'd like to get a rough estimate of how much RWHP and RWTQ I am running. Also, if you want to do a second set of #s after I add in soon to be bought 70mm TB, 76mm MAF, and 24# injectors. I will be dynoing soon, maybe dyno tuning to really wring out the power, but for now any educated guesses will work. I'm guessing somewhere near 280 RWHP, and I have no clue on RWTQ. Mods are in the sig. Oh, if you want to give a guesstimate 1/4 mile ET that'd be cool. I'm a pretty good driver, my launch is my weakest thing but I'm working on it Thanks guys!

EDIT- Timing is set at 14* BTDC and fuel pressure is set to 41 psi.

The previous owner of my car did HCI plus a host of other bolt-ons. He claimed that he had the same mods as Ford had done to its 345hp crate motor plus a few other minor ones, so he figured the car was making about 350hp, give or take a few. At first, I was pretty skeptical of that figure, but after driving the car, it feels significantly quicker than my old '93 LX notch. And this is in an '89 GT convertible which is something like 300-400lbs heavier, IIRC. I'd guess that the motor is making around 300rwhp.

Given that my car has a few more minor mods than yours does, I'd say that your 280rwhp is well within reason.

schweet. my eventual goal is an even 300 to the wheels. I'm hoping the MAF, TB, injectors, and a good tune will give me that.

Are the heads ported? Are they milled? If everythings box stock, with your mods your planning you wont see past 275rwhp at best.

Yeah I don't know about those numbers on box stock set-up...I made 291RWHP untuned on ported and polished GT-40X heads, ported GT-40 intake, FTI cam and the rest of the bolt ons...dyno would be the best as far as accurate results...You probably have around 300RWTQ hence the car is very torquey and sometimes gives you an illusion of having more HP than it does...If it helps any a 345HP crate motor with box stock GT-40X heads an E cam and a Cobra intake and the rest of the bolt ons...made 270RWHP...that I have seen...

250rwhp and 295lbft. This is what I've seen a car do on the dyno with a set up like yours.
