Hey guys, i was just curious if anybody could give me the max mph for the first three gears. with no tach in the brighton i just wana have a decent idea what the max speed is at the top of the first few gears so i dont have to find out by hitting the rev limit. i gota ice race im going to on thursday so odds r good i might be getting close to maxing out the first 3 gears with tire spin. any rough estimates would be great, thanks guys.

First - 30
Second - 50
Third - 75
Fourth - 100
Fifth - Speed limiter at 135. :O

When I was doing the donuts in my BK last night, in third it was just short of the rev limiter and the speedo was pointed right at 80, so not sure about that one.

For the record, at each of these speeds is when you will hit the rev limiter. So you want to backoff a few mph, because it is real easy to spin that last few mph/RPMs to redline. I was in 2nd gear getting ready to pass a guy and didn't realize traffic was picking up speed. I gunned it to get around the guy not realizing I was at 45mph, and was hitting off the rev limiter instantly. Not fun. :lol:

Have fun at the race and get some pics! I'm missing friday's race because of job training :(

I was rounding down a little.

first - 32.5 mph
second - 53 mph
third - not quite sure
fourth - 104 mph
Fifth - 135 (governer)

Really? Mine hits at exactly 30 and exactly 50. I don't know about 3rd, I think its around 85 or 90.

yeah, my rev limiter is at about 6,750 rpm, at rev limiter, it's usually a little beyond an even speed mark.

I seem to remember third being right at 6,000 rpm and the speedo showing 80 mph exactly. :P That's from doing donuts in the parking lot, not actually moving that fast, though, I did get it to bounce off the rev limiter once in fourth on the way home...

Different redline, different gearing.
