Help! '01 Z06 cutting out
I have a '01 model and had it for a year now. Just yesterday, it started to cut out when I am in first, second, and third gear only when I hit 5,000 RPM. This has never happened before. I usually go to 6,500 RPM with no problem. I now can hit 6,500 RPM in fourth, fifth, and sixth, but not the first three gears? Any help out there from the experienced ones??

I'd check all of your plugs. This happened to me in my '98 LS1 Camaro. It turned out that one of the plugs was cracked and was only working about half the time. At high engine speeds (with relatively lower loads, such as in the first three gears), the engine had a much greater tendency to cut out and miss. Just remove and re-gap all of the plugs and see if any are bad.

Are you sure you hit 6500 rpm in fifth and sixth? That is 176 mph and 264 mph, respectively! Are you a pathological speeder?! :rofl:

It must be that TX gas, 267 in 6th gear, I gotta get me some of that

Re: Help! '01 Z06 cutting out (vettezosix)
For my 6, the dyno showed 6500 rpm at about 142 mph. Although I don't have any accurate numbers for what fifth does, I have heard reports that it hits a top speed of about 175 in fifth. Some of my friends tell me that the 6 reaches it's top speed in fifth and that sixth can't pull as high a top speed. I'm not sure I believe them. The math for the equation (including stock wheels and tires) works out somewhere north of 255 mph and south of 275 mph. It is hard to calculate accurately because many factors affect the calculated result. For example, variables affecting the diameter of the driven wheel and tire combination include things like tire pressure changes due to heat and tire profile changes due to rotational forces. Believe me when I say that I am no math genius. However, I am certain that it takes all that math to figure out what speed you would be achieving at 6,500 rpm in sixth gear because I believe that, long before that theoretical speed is reached, you will reach a point where forces against forward velocity match the forces available to provide forward velocity. I don't know what that top speed is, but I am confident that it is nowhere near 255 mph.
Wow! what a long-winded preamble to the question: What is the "real" top speed you can get out of a Z06?
