Dyno numbers

302fordracer · May 4, 2005

my mods are in the sig...it was a little wet today which may have affected the numbers slightly but prolly not...My biggest downfall is I was running really rich...at 2500 rpm I was running 12.3 to 1 a/f ratio and at WOT I was running 10.9:1 a/f ratio...so I need to lean it out I am too rich obviously...and timing was also set at 10*...anyway it was a MUSTANG DYNO and here are the numbers:

230 rwhp at approximately 5300 rpm and 266 rwtq at 4000 rpm...

Well what do you guys think?? I wanna try a dynojet cuz I wanna see how much more it says I got..I think that I did pretty darn well for 92,000 miles on a MUSTANG dyno..

Pm'ed you about parts..

With your your fuel being too fat and your spark too little I would say you could pick up 10 to 15rwhp if you get those two things dialed in more like they should be.

Bump the timing to 14*. Why didn't you bump it on the dyno?? Try pulling 3-4psi of FP out. Also, clean your maf element wires. 230rwhp is good considering how rich you were.

Wait, whats that sct custom tune listed in your sig?

My '94 GT pulled 196rwhp stock with 186k for my baseline. That was with 14* of timing and a K&N airfilter though. Also that was on a Dynojet.

You should have pulled a baseline Dyno first so you would have something to compare it to... Say yours was pulling like mine at baseline and now you've bought and installed all of this...

GO: trickflow street heat manifold,75mm throttle body, 76mm maf, sct custom burned computer, bassani o/r x-pipe, asp underdrive pulleys, mac shorty unequal length headers, 3.73 rear gears, Green performance air filter, flowmaster 40s

... And now you're only making 34 more rwhp.

But for arguement sake let's say you were pulling stock, which would be around 186rwhp, well then you've added 44 rwhp with all of your mods.

the sct was tuned off the dyno and he obviously messed up bad lol...I will be taking back to the guy to have him tune it on the dyno next month probably...but yeah I know there is a lot left in it seeing as how it was way rich..

you forgot to consider how rich I was running and how little spark there was...and the fact that your numbers were off a dynojet and mine a mustang dyno...

your mods are very similar to mine. sorry, i have not done any dyno runs so i have nothing to compare with you. the biggest diff is that i have ported heads and yours are still stock.

230/.85 = about 270 hp at the flywheel.

215*.85 = 185 rwhp stock

seems to me you are up about 55 hp from stock (at the flywheel), about what i would expect from your mods ...

well the tech said that our cars especially with the mileage mine has (92K) he would expect closer to a 20% loss so he estimated 274 crank (not quite twenty but closer than 15) and 318 torque and no one forget..I am running way rich...I guess I was just wondering what you all expected I would get if I bumped the timing and corrected my fuel...?

I somehow missed the sct chip in your sig and that could explain why your at 10* with the dizzy.

The fuel is still way too fat so I still think you might be able to pick up 10 to 15 rwhp if you get the fuel & spark dialed in.

the chip was burned with the same 10 degree timing as the base ...there have been no timing advances...
