at a local track this past weekend, there were 2 supercharged S2000's and it looked like they both had the same superchragers. Well, either the drivers were REALLY bad, or the sc kit doesnt put down that much hp.

FWIW-I think the best time was MAYBE a 13.9X @ 103mph and this was when the sun was down and the temps under mid 70's. Also, the ultimate-racing.com turbo kit ran 12.6 @ like 114 on stock tires. Maybe all you sc owners should be looking into turbo kits.

I am not surprised at all. In most respects a comparible Turbo set up will be superior to most SC set ups.

I'd love to know what psi that ultimate racing turbo user was pushing to run such a good time on street tires.

With my custom turbo kit running 0.4 bar ~5.88 psi I ran a 13.9xx at 103.4 untuned and just slipping the clutch at about 5k. 2.4 60ft time. I'm suprised the sc s2000 aren't running low 13s.

Yea bad drivers, the s/c S puts down minimum 290 to the wheels. That should be capable of low 13's in the 105+ zone.

If you launch it at 8K RPM. The centrifigal blowers do nothing to change the lack of low end power in the S2000. The trap speeds speak for themselves. 103-105 mph is a good mid to low 13-second car, even if they turn a 13.9; there's more to it than meets the eye. Try to run one of those cars from a roll and see how it does. Turbo, nitrous, or a crazy launch w/ supercharger is the only thing that will put an S2000 into the low 13's and below.

13.51@107.1 was the best i got the 1 time i took it to a 1/4 track. no upgrades to diff and no desire to kill drivetrain so i can say it went a couple 10ths quicker. lets not forget the SC power comes on strong in middle RPM's, not at low/sane launch speeds.

you just cannot bench race the times expected based on total HP, you have to look at where the power is at. coming off the line, a SC car is not going to be that much faster than a stock one so that initial point to make all the time is not really there. we start to pull hard and it shows in trap speed.

besides, our car is not about launches, it is about the twisties.

Could it be possible that the drivers didn't do a hard launch? If I was SC'd, I wouldn't. I'd rather slip the clutch and lose out on the times than drop the hammer and kill the diff. ~300hp to the rear wheels must put more stress everywhere than a stock S2k at ~200hp. That's just me though.

The trap speeds you saw would make for a solid mid 13's car. I'm sure that if the SC S2k's were on an oval track or the race was extended to a 1/2 mile, the difference would be a lot clearer.

A stronger diff , gear reduction (4.44) and a roots-type blower would be ideal for that kind of driving since boost would be available sooner than the Paxton chargers. Too bad those Eaton blowers are only for RHD cars only.

Definitely BAD drivers...............There's a SC s2k here in Denver running 13's at altitude..........that would be 12's for all you sea level folks out there
