Been reading the thread, and it reminds of the MKIV Supra club my old roomie belonged to. They used to do canyon/banzai runs back-to-back, with open invitations to anyone who wanted to attend. It usually ended up being about 20-25 Supras upgraded to various degrees (from simple boost/fuel controller to full single-turbo upgrades in excess of 750 rwhp), Porsches, BMWs, Audis, sometimes a Ferrari, and always a number of NSXs. One NSX owner who always showed had a Comptech supercharger and full suspension work. Without fail, for at least 4 straight months, the NSXs would have to abandon their run, simply because they couldn't keep up. If they got lost in the twisties, they'd meet us at the rally point for the banzai run, and then proceed to get left behind again. Not saying the NSX sucks, but it is significantly behind the times in terms of technology and performance.
Oh, for those who don't know:
Canyon runs: usually Malibu canyons between PCH-1 and 101, Angeles Crest, or Ortega Fwy (in Socal).
Banzai runs: top speed runs. Usually on 101 north of Los Angeles towards Camarillo, or 15 Fwy east towards Las Vegas. Always done early, early in the morning, and always with lead and chase cars to try (if at all possible) to avoid any sort of traffic.
I realize that driver skill has a lot to do with it, but it's an interesting trend that I continually noticed for months on end.
Another anecdote: I have 4 (affluent) friends who have had a Sunday morning drive for the last two years up in San Francisco. Canyon driving to the ocean, then a speed run up the coastline. All four guys have race driving experience (track, drag, auto-x), and are easily the 4 best drivers I am acquainted with. Cars involved over the last two years:
2003 BMW M3 (lightweight BBS wheels/suspension work only)
1997 Toyota Supra TT (fuel/boost, suspension, lightweight wheels, around 450 rwhp)
1996 Porsche 993 TT (enlarged turbos, suspension, wheels, around 650 rwhp)
2002 Chevrolet Corvette Z06 (upgrades unknown)
2004 Dodge Viper (upgrades unknown)
2003 Ferrari 360 Modena (stock)
2001 BMW M Coupe (stock)
In the last two years, the first two finishers in every Sunday drive was always the Ferrari, followed by the M3/M Coupe. Regardless of which other car ran, the M cars never finished worse than 2nd. I think that given the company in the list, that is very impressive.
