I had hit 174 ( 6k rpm ) before, but I had to top her out, lol. So anyway...

0-150 went by pretty quick. I eally didnt notice any floaty feel until probably after about 150. Even after that, it still felt "safe", lol. As safe as you can feel at that speed. Wasnt lifting or shaking, and I felt I had pretty good downforce and track with the road. Didnt notice the hood shaking at all. I dont have any scoop though. I watched the tach creep up on redline at 6k, then stayed in it till 6250. It actually was pulling rather well from 150 to around 170, but seemed like every mph after crept by. 6k to 6250 seemed like it took at least half a mile. At that speed, It did get slightly floaty, but still felt ok, not 100% secure needless to say, but not insanely dangerous.

What was trippy, was after we slowed, it felt like we were doing like 25 mph, and I looked and we were still doing 120. That was rather freakish.

If your curious of your speed and revs in certain gears, this might come in handy. http://www.race-cars.net/calculators...alculator.html Ya just have to know some basic info for it to work.

As far as being unsafe, I hit 181 in the stang not too long ago. Had to use that calculator to find out my speed. Took it to rev limiter in 5th. No reason to ever do it again though, lol, unless I change my gearing. Thats as fast as she goes. I did it as safe as I could though. I mean ya gotta have some fun.

FWIW, my 05 GT redlines at approx. 100 mph in 3rd, and I've compared its acceleration both ways at high speeds(70-90)....leaving it in 4th and rev matching in 3rd(as high as 5.5K rpm). The results are indisputible. It definitely accelerates faster in 3rd.
