What happened to me probably doesn't happen very ofter. There was some serious money put into that car. Between 4,000 rpm's 7,000 is where the sweet spot is in a Z and when I down shifted I was at 5,000 when I stomped on it.

I think you're probably gonna get flamed by one of our Canuk bretheren (1990 415) on this. They KNOW about this kind of stuff.

By my rudimentary calculations,

1)Stock gears (3.45:1) (4th gear, 1:1 final drive ratio)(25.4" tire dia), speed @ 5,000rpm = 109.6mph, not 65mph, rpm @ 65mph would be 3,000 rpm.

2) to be at 5,000 rpm @ 65mph, you would have about 5.80 gears

3) if you mean that you downshifted to 4th @ 65mph, then "cruised" up to 126mph, when you stomped on it, still in 4th gear, you would have to have 3.00 gears to be at 5,000rpm.

No flame intended, just considering what 1990 415 had to say, which I would agree with in a stock geared ZR-1. With my gears of 3.73, I would have probably gone to 3rd at 65mph. Any which way, it still sounds like you got bit by da snake.
