97 Mustang Cobra 5-spd

flowmaster weld in mufflers
offroad H pipe
BBK CAI
its live axle (no power gain)
kenne bell 6 lb supercharger non intercooled
kenne bell boost a pump

what should it have at the wheels and also the crank... this car has 305 hp crank stock...

SXGT

flowmaster weld in mufflers 7rwhp?
offroad H pipe 7rwhp?
BBK CAI 6rwhp?
kenne bell 6 lb supercharger non intercooled 70hp?
kenne bell boost a pump ????



idk i cant calulate Forced induction stuff to well
sooo +395HP?? []

flowmaster weld in mufflers (why do people do this? The gains are minimal, as the stock pipes suck, too): 5 hp

offroad H pipe: (with the stock cat back, the improvement is limited) 5 hp

BBK CAI: 3 hp

kenne bell 6 lb supercharger non intercooled: 100 hp (according to KB website)


305 + 113 = 418 fwhp

416 x .85 = 355 rwhp

being that its forced induction i was generious with the mods power. So yea your in the 400 crank / 350rw ball park.

hmmm.... he ran at the track on friday.... his best time was a 9.2 @77mph with a 2.1 60'..... those dont seem like good times at all.. and we hooked a boost gauge up to his car... hes getting 8lbs of boost it shows...

I would def check the tune.

04BlueGT

Part of the problem is that 60' time. Street tires, I assume? Does that year have IRS?

With 8 psi, he really needs to cool it. He's killing his power with the heat he's generating, but the tune could be part of problem.

I looked at the KB website for more info. I underestimated the power of the 6 psi on that car. He should be OVER 450 at the crank with just 6 psi. At 8 psi, 475, maybe more. We're talking 380-400 rwhp. Yeah, should be faster than that.

I don't know what you did to calculate it bud, but lets crank some numbers out.

6 psi, just taking into account the pressure, he should be making 430 at the crank. That's 305*20.7/14.7. Heat taken into account, should be around 415-425 at the crank. For 8 psi its 471 by that method. So drop that to 450-460 because of the heat. ~380-400 rwhp when taking into account the O/R pipe and CAI (CAIs do something when you boost it afterall).

And then, take into account for some loss due to the belt drive and you've dropped to around 360-380.

yea, they actually told him they dont make a intercooler setup for his car.... but i was thinking, cant he put a eaton heat exchanger in his car and will it fit in the blower?
