I went for a speed run last Saturday just to see what my 2000 would do...I
hadn't tried a top speed run since prepping the car for CSP several years
ago and with all this talk of speed records...I just couldn't stand it!
Anyhow, I ran out of steam at 6350rpm in 5th, 3.89's, and 205/50/15. Works
out to about 133mph although the speedo (Autometer) said 142. The car
probably would have gone faster with 3.70's or larger diameter tires, as
6350rpm is a bit past peak hp. BTW, the 6350rpm figure is not a guess, it
was plucked from my fuel computer.
I'm curious as to how many of you are relying on speedometer readings and
how many are actually calculating speed? Also, are you using a U20 or
something else, and how did the car feel at top speed, handling
wise...fairly secure or downright scary? Mine felt rather twitchy, but
that's expected of a car set up for under 60mph autocrossing. I don't think
I would have even attempted such a speed run with stock suspension/tires.
Non-Roadster content: Anyone got an impressive personal top speed in a
non-roadster? I used to own a '70 240Z with a 13B rotary turbo...intercooler
filled the entire nose, header wrapped to the front of the engine where
there was room for the turbo, 3.54 viscous LSD (from a Q45) and 225/50/16. I
hit the rev limiter in 4th (8500rpm) and got scared. That calculated to
about 185mph, and it could have gone faster...with someone else driving it.
