NPI dyno numbers!!!

[98COBRA281]

i hoped she would have been a little better. but she put down 225.5rwhp, and 270.2 rwtq my af ratio was good, between 4000-5600 rpms it was between 11.5-11.8

 

[CobraRed_96_GT]

Shouldn't your a/f be around 12.9?

 

[98COBRA281]

not sure, but he said it was good

 

[CobraRed_96_GT]

Low/mid 11's is boosted a/f territory. 12.8-13.1 is where you want to be unless im mistaken

 

[02nightmaregt]

Damn i thought it would be quite a bit higher than that. Just a reason to keep modding

 

[d98gt]

That sure is a low number for a car with cobra badges

 

[Tim2002GT]

I would think you could pull a little higher #'s if you leaned it up a bit. Good numbers regardless!

 

[98COBRA281]

yeah i though it would be a little higher than that.. making it leaner will make more power?

 

[98COBRA281]

yeah P&P pi heads, cams and long tubes

 

[98COBRA281]

 

[mustangman9812]

If you hade Longtube it would have been better. L/T's = Next Mod

 

[Winters98GT]

Good deal man. Glad you got some numbers.

youll proboly gain 5rwhp with longtubes.

 

[98COBRA281]

it makes me want to do pi head swap so bad

Those are decent numbers. That is right in the area where stock 99+ runs and you don't have the heads themselves. Mine put down 229rwhp with your mods minus the T/A, no-cats and tb/plenum so we're in the ballpark but we can't compare directly different dynos. I've also toyed with picking up come heads as well, but with only ~10rwhp gain, the amout of work, and the need for higher and more expensive octane keeps me way. I would only do heads if cams were part of the equasion.

How does it feel/drive to you? Been to the track?

I'm sure you have at least 10hp by getting the AF where it should be. That's fine for boosted car, but doesn't make good power on an NA engine.

Seems to me, when you increase the airflow beyond what a stock engines would move, the computer compensates by making it extra rich. Adds a margine of saftey to ford and those who modify their engines I suppose.

yeah those are the SAE #'s, when he put the weather correction on it went to 230hp, 274tq, the car runs great and strong, feels like it has more the 225hp , but the dyno dosent lie!! no i have not been to the track.. i see you ran a 13.7, thats rely good, i would love to break into the 13's, even with a 13.999

 

[96GT281]

i dont even want to bring my car to the dyno. 193/240 ill probly get out of it

You'll get there, i got a 13.97 with NPI heads and cams

 

[hotmustang331]

Yep your car is running VERY rich. Needs be leaned out alot. Really you want to be running around 13.5 A/F at the rear tailpipe....maybe a bit leaner. You would probably make 235-240 by leaning the thing out.
Great job none the less!

 

[LaserSVT]

Good job buddy And I agree with everyone that a little less fuel and youd see another 5-10 hp Bet that thing gives a nice pop under a heavy load between shifts
