Finally killed a new Mustang GT!

[Advancedynamix]

Around 140 the Festiva hits a wall. That's where the slippery big bore cars will pull away. I imagine the problem would be solved with more TQ for a few more miles per hour. From my past high speed expiraments, when the car hits that speed wall, you want to pay attention. Going beyond that can awaken the demons. Lol

I hit my wall in the festy! I dont really have a need to go faster then that in this car. If i need more id rather get on my bike! It was fun showing the mustang who is boss tho.

I was afraid of my hood ripping off the most. If i go to do that again ill have to take the hood off 1st.


It was great that at 1st he would not bother with me! Overkill is a true sleeper indeed!!!

That's plenty fast enough to get you thrown in jail and the car impounded and maybe even crushed.
Or you or others killed.

Sorry, had to. I really just love the drag strip.

Ok, found it.

For a factory stock manual transaxle, the 5th gear ratio is 0.692. The final drive ratio is 3.77.

So: using the foregoing numbers, the calculated speed at 7K rpm in 5th gear is 127 mph (crosschecked with this calculator and this one).

If the entries and thus the attendant calculations are correct, you were really rolling.

This isn't a stock trans, its a G5MR. Final drive is 3.85 and 5th gear is .79 I think.

Yes it was plenty fast! I will make it to a strip this summer i hope. IDK tho i dont really want to break my trans going for a 1/4 mile time. Time will tell.

Mike said stock. Using your numbers, I (re)calculated 124 mph. Still fast.

Awesome kill. You're definitely making some good power

Stock get series!

120mph 130 140 150 I don't really care the actual number. All that matters is that I didn't hurt anyone and that I won!

[skeeters_keeper]

nice pull!

The 5th gear swap really helps on the highway, for cruising... if you ever intend to drive that thing very far (like to, say, madness in the fall!).

lol....What that guy must have thought?...priceless.

I ran these numbers through 3 different calculators and got 158+ mph. That's with a 23.2" tire diameter, which the 185 70 13 is rated to have. A 23.2" diameter is awful tall on a lowered Festiva though.

I got that on a couple calculators too, others gave me 125.

I remember JT maxed out at 163 with the 5th gear swap at 7200. Don't know what tire size that was though.
