Damn 14.4 with a 2.3 60' on a basically stock mustang?? Thats pretty good!


I was hot rodding my car around last year and i had it floored...pushed in the clutch to shift to 3rd...and the pedal got stuck on the floormat, i pegged out the tach for a few seconds... (7k ++)

It wasn't anywhere near 7000... they have rev limiters at 6250, so you were no higher than that!

I dont know whether my tach is off that bad, or my limiter has been deactivated but I did not hear it jumping off the limiter at all.

The needle will "bounce" past 6250 but that's just the crappy stock gauge.

I'm running a Malory distributor with a built in ignition and no limiter...i know for a fact i've revved past 6500...but then again i did blow a head gasket earlier this year

Ouch...

But I don't see it making any power above 5000 (never tried it) but I understand wanting to shift into the powerband, to what seems like around 3000 for me. I mean I still have the stock intake and little throttle body. Honestly I don't know what my needle drops to when I shift, I mean where the RPM ends up once I shift from 2 to 3 or whatever, it could 2500, it could 3500 - I don't have a clue lol

I'm not game to try it on the street to find out either, next track time will be in october unless I go earlier to practice. I should have a Cobra intake, larger TB, and some Nito 555's by then.

I agree about the stock rpm, it sucks. You really notice it once you get an Autometer RPM guage.

You mentioned setting your shiftlight, but in case you are still gauging RPM's off the stock tach, they are not very accurate. At 6k on the stock gauge my engine is really only at 5,500 rpm; verified by chassis dyno.

No, I ignore the stock RPM... I use the Autometer monster tach with shiftlight

I shift mine above 5,000 all the time it's not going to hurt it. Try atleast 5,000 next time your at the track.

The reason they tell you to remove your floor mat at the drag strip.

I launched my old car and got to 5k but when I pushed in the clutch and took foot off the gas the rpm spiked to the universe and beyond but I was able to pull it into second with a quick full throttle shift and then into 3rd with another full throttle shift and just turned off the ignition at the finish line and put it into neutral. Duh...the gas pedal got stuck on the floor mat. Pretty impressive 1/4 mile time tho I never did that again tho. No harm done as it was only momentary.

The arguement about shifting with the torque or the HP curve will go on forever. Your times are impressive for what you have and what you're doing. Consistency wins the money in drag racing anyhow. That's why I always raced a slushbox at the strip in "D". Sticks are more for road course or autocrossing.
