This has been gone over before and I think the general consensus is that 1.98 is about the best that's ever been done with anything that resembles a stock street tire on a 5spd SC at even moderate power levels. I did the 1.99 while running a 14.5 @ 95mph and making about 240rwhp back in 1995. I was running 255/50/16 Falkon tires and a stock clutch. The combination was just such that I was able to launch at about 3000-3500rpm while slipping the clutch and not really spinning the tires. Good track prep was a big part of it too. I thought I toasted the clutch on that run but apparently not.
Most of the time I'd say that anything close to 2.00 or better from a 5spd is excellent. 2.1 is good. 2.2+ sucks.
Personally I don't recommend any street tires on a 5spd at the track. If you don't feel the need to "launch" the car and just drive it off the line drag radials actually work ok because they'll keep you from spinning halfway down the track. If you want to launch, then you need ET Streets or slicks.
