I run pretty consistent 13.0's at about 107mph when stock and with just software run 12.9's at about 109mph. I'm curious about the M3 'sports package' as well...

 

How much slower is an STi compared to the M3?

 

I'm sure from a dead stop an SC S2000 has a better chance against an M3 than from a roll. The M3 has a bigger, flatter tq band. He guns it, it goes. The S2000, even SC'ed you will have to play with the gears & revs. Similar to an M3 or a 911 vs. the Corvette (C5's) from decent speed rolls the Corvettes are quite a bit faster, but from a standard 1/4 mi. times they were very close.

Anybody with a UR turbo run an M3 ?

 

I pulled my buddies Vert M3 2002 with my Comptech w/ 7 psi pulley several times and have yet to lose to him!

 

Do mean that backwards? I had a much tougher time getting my supercharged S2000 off the line, compared to going from a roll-just use the lowest possible gear, and nail it.

Additionally, the broad torque curve would also come into play for the bimmer, since more torque means less of a fine line between wheelspi/bog.

 

No it's how it sounds. A nice broad torque curve gives you much lower acceleration times in the 30-50, 50-70, etc times. If you look at several cars such as the M3, 911 (996), & Corvette (C5) they were all running similar 0-60, 1/4 mile times but when it came to the 30-50, 50-70 mph tests the Corvette was faster than the other 2. Personally I have seen the BMW M3 run step for step with the Vette on the 1/4 mi. track, but when it came to even being in the right gear for fastest acceleration times at freeway speeds the Vette pulled hard. there is a video on the net that showed this (actually I think I pulled it from here a long time ago).

Hate to generalize but everybody has a tougher time getting cars off the line than simply pushing the peddle down at speeds, it's not just SC'ed S2000 owners, but that is applicable to all cars with power (wheelspin/bog).

 

Well, are you speaking from personal experience, or just touting theory? Because from repeated first hand experience, I know that the S2000 is considerably tougher to launch cleanly, and adding a centrifugal supercharger does little to alleviate the problem.

I can leave the line pretty hard in my Z06 on street tires, without even really trying. Whether rolling into the throttle, feathering the clutch, just dumping it, slipping it at 1500, slipping it at 2500..........its all good. Similarly with the M3, which has much more torque to play with, youre not crossing your fingers every time you drop the hammer, and hoping that you will hit that "sweet spot."With the S2000, youre pretty much limited to a very high rpm clutch dump that will land you somewhere around 6-7k by the time everything gets sorted out. By the time you take into consideration the fragile diff, the strain on the clutch, and all other associated parts, compounded by the fact that the blower makes its power up top, I'd be far more confident of an S2k prevailing from a roll. 1-6k in first is a pretty serious dead spot.

For instance, I ran a friends stock 350Z, and we went from about 60mph. I left it in fourth to see what would happen, and he put a buslength on me before I started making any noticeable boost.

Second time around, in third, I immediately shot out on him thanks to being on the big cam to start with.

I think it would be much easier to play with "gear selection" rather than play with the clutch.

In other words, I dont agree with you.

 

Still waiting to hear about this mysterious sports package. Guessing competition package?

 

I've not driven a SC'ed S2K, but I have run the 911 & the M3 against a Vette from speed vs. from dead stop. Dead stop we were pretty even. From speed it wasn't close, the Vette put several car lengths on us, even though we were in the right gear in both instances with the 911 & the other time with the M3.

Notice I didn't say anything about clutch & drivetrain longevity. I'm sure if you abused your car a bit you could get good launches & cut down on your 1/4 mi. times.

 

The proper way to race and SC S2000 from a roll is to put it at 7,000 rpms and gun it.

A 300rwhp SC should have to problem with a stock E46 M3.
