To be politically correct here's my post on IS300.net



What's up guys,

Yeah Unicron and I went at it a few times, and I absolutely agree that launching is everything.

My best launch- 2nd run I had 2-3 lengths (according to my friend behind us)
Unicron's launch- 3rd run he had half-1 length before his missed gear, heck I missed as well going from 2nd to 5th. We both shut off there.

Last run was right on. I had about a car length, but did not pull on him after 60.

Conclusion, the winner on all the runs won out of the launch. Our cars have proven to be formidable opponents.

Unicron- I can still smell my clutch! After last night I concluded that I will need new rear tires (they starting slipping hysterically after our 2nd run (thus the over rev and cluth slip). For those of you who flame the S2000 I honestly think you should run one before you talk. As for the run between my friend's CLS & Unicron I couldn't tell. That's between them.
Most importantly, Unicron is the nicest guy in person, and is by no means arrogant. He has backed up any talk in his defense. I'm sure we'll run again in the future.

Dragonx... I'm having a ball with the S2K! Been on track at Charlotte, Going to Mid Ohio in April, and VIR for three days in July...and the clutch will love me for it.

Unicron... read my posts! I agree that a properly launched S2K will beat a 330 CI from STANDSTILL! I was rolling at 5-6,000 rpm in first. A run to 90 mph from a rolling start is a no brainer. Sure, a rolling clutch drop might have netted a more few feet. I was surprised too...I was there... I saw it! Once he's got his BMW's mass moving, the cars are closly matched to 90.

I know the guy that I ran with is competent and he was trying hard...during the run when I was behind him, I heard the tires bark from first to second, and chirp from second to third. How can you be sure that your opponent was skilled and trying?

Unicron

Fair enough...I don't even know if the 330i I ran with was a automatic or manual.

I believe the reason why you ran even with the 330i was because you started racing him when you were below vtec. This is a big weak spot of the S2000. I got smoked by an M3 when I was cruizing in 2nd gear @ 2000 RPM and the M3 next to me gunned it. I was tryig to shift to 1st, but didn't match the revs correctly.

The two scenario's below will give you different outcomes.

a. Say you two were cruising in first gear, and your RPM is at 7000. And you both hit the gas.

b. You two are cruising in first gear, and your RPM is at 5000. 330i hits the gas the same time you do a double clutch @ 6000 RPM.

c. You two are cruising in first gear, and your RPM is at 5000. And you both hit the gas.

In scenario "a" and "b", you should have been ahead.

When you are already moving and the person you are racing jumps the gun the same time you do, the fact is...without vtec...you are in trouble.

Another thing I have learned about racing when you are already moving. Timing is everything. Whoever has the jump has a bigass advantage.

I posted a topic where I had the jump on a newer Firebird Formula coupe, and he had a hard time leaving me.

BMW 330 is very closely matched with the S2000 in the straight line. S2000 will probably win if both cars are launched perfeclty (though by no more than 0.3 sec or so). On the other hand if both cars are not launched perfectly then more than likely the 330 will win. Also, the faster you go, the better the 330 should perform because of it's 'slipery' airodynamics. Over 200km/h the 330 should be comfortably faster than the S2000.

Here's some side info from a recent track test here in Aust where they had the 330 - it had a terminal velocity of 206km/h in the 1000m sprint ... S2000 will have a hard time matching that. Also, they had the car on the track and compared to an S2000 lap time from a little while ago, the 330 was 2 secs slower per lap (1:45.5 vs 1:43.6). That just really shows you how well sorted the 330 is ... after all, it's a heavier car and is is tuned more for comort and luxury than racing (unlike S2000). Losing 'only' 2 secs on the S2000 makes it a very quick car even when corners come into play.

btw, Just for reference value - the WRX lapped in 1:46.7 and 200SX lapped in 1:46.4 ... that makes the BMW 330 a faster car 'point-to-point' then either of these performance machines. 330 is a car not to be taken lightly (even by S2000) ... now just imagine what the new M3 will do to S2000 ... I don't think it'll be pretty :-)

Damn, I didnt' know a 330 was that fast either... but another 10-15k and might as well go for an M3 then.

Dragonx

Allaann,

I'm glad you are enjoying your track time with your S2000 but you need to realize that the girl that you were dicing with in the 330 is right now spreading it all over the BMW-CCA chat site that she took you in the S2000 and anyone who says that the S2000 is faster that the 330 is full of it.....yada yada yada.

Next thing you know, every Bimmer pilot will be swaggering around the coffee house telling anyone who will listen that the German engineering is far superior to anything out of Asia.

You have a responsibility to all other S2000 owners. We don't want to have a target plastered on our bumpers. Either run or don't - that choice is yours, but if you do go - GO!

[B]Ok, I've done some research and here are the numbers:

If one of you good launchers met him at the drag strip you'd probably grab a car length at the start and win by that same car length at the end of the quarter.

Yeah, something is up. There's no way the 330Ci can keep up that well with the S2000. Even if Allen did race the guy and he kept up... something wasn't right. Maybe I'm trying to deny the truth... but I am not biased toward the S2000 in any way as I am seriously considering the 330Ci as well as the S4.

If the 330 is in fact that capable relative to the S2000, what a pleasant surprise

Dragonx, touche.

I entered the 330 specs from the BMW site into Cartest a simulator i have learned to trust over the years.

Unless BMW has seriously underrated that engines capacity it is slower then i thought. We are looking at a best of 14.9 @ 95.9 MPH which equals a trap of about 92.0 MPH at a dragstrip...

Also it reaches 100 MPH in 16.1 seconds compared to the s2ks 12.1 seconds ...

The point is there is no way in hell this car can run with an s2k unless something is wrong. Either, s2k is slow or bmw is modified. In fact, it won't even pose much of a threat to a Type R.

I revise my 14.5-14.6 prediction. I don't see how it can do better then a 14.7 under optimal conditions with the best driver. The only way it can is if it is producing more power then BMW is saying it does.
