ok i am on this mustang site and we were talking about this and that. basically blah blah blah. but anyways i told this guy that in my t/a that i could go 150 in 3rd gear and he told me that when i brag that it should be believeable. ok so it was more like 140 145. any of u automatic guys done this before? i have 3.23s in the back plus whats in the sig? he told me his 96 vette couldnt do it.

I have only gotten my car just a little over 130 but I know it was in 4th.

I do have a site that calculates with gear and tire size for your ride.

It shows 142 mph at 6000 rpm in 3rd gear with 3.23 gear and 275/40 17 tires.

Yea, I have seen it with cars with higher revving cams/higher redline.

My car has went 150mph @ 6800 RPMS in 3rd on the dyno. I have had it to 140 in third on the street before I let out. I believe it is possible with some mods and higher redline.

how fast can you go in 2nd gear?

ActionJack

If you change the rev limitor sure. But you will be putting pressure and heat on that tranny and the motor will be pumpin pretty hard and fast.

I hit my rev limited beating a mach one day going about 150. I had it in overdrive not thinking about it and we both thought i broke something. Actually i just htink the speedo was about 8 mph off. 150 is up there for 3rd urs may be off too.

my lt1 did 90 in second....

I meant higher than the stock 6250 rev limit, not higher than 6800.
This was done at TEA while tuning the car, it's set to shift at 6500-6600, but for the tuning runs it was left in 3rd and taken to red line (6800) on each run. I don't see the big deal, it wasn't like it was for more than a few seconds or so. Took it up to 6800 then let off and let it slow back down. The factory tach didn't read 6800, but the TECH II did. The speedo is dead on also, and it read 150. I have it on video and would post it if I knew how. As far as the 140 street run, the car was in D (OD) but it was still in 3rd when I let out at 140, again, I don't do this all the time.

thats what i was about to say ... lol, thats why i asked him that because mine would do 90 in second if i had it in 2 ... 90 was pegged out though

i thought he may have had a 2.73 but a 2.73 will go over 100 easy cuz ive driven one

i can clear this up quickly, be right back ....

well i just read that someone already calculated it ... only problem using the calculator is that the converter may not have been locked up or was it? ... if it was locked then it should be dead on

I was shifting into 4th at that speed w/ my 2.73's FWIW.

My LT1 has been pegged. So thats 155-160 I guess. No idea what gear.
