any thoughts on the outcome?????? how close would it be????

 

off the line or freeway speeds?

 

don't ever think that CLS-6 + SC => M3.... SC can NOT cure the shortcoming of FWD with a lot understeer... Actually it makes more dangerous...

But, in a drag race if the CLS-6 with SC making some more 300 WHP can NOT pull on E46 M3... the CLS-6 SC guy should shoot himself in the head.... Joking OKay...

 

Nashua,
examine the numbers........

Well it REALLY depends on the setup of both cars. For instance, and please this is hardcore mag racing here but just as a hypothetical, if the Comptech S/C 6mt w/ the super leggra wheels and sticky tires ran against the m3 it would be closer than you think. Since there RWD is better off the line iit would be difficult to to say how much the additional trq of the S/C cls would negate the downside of the FWD. HOWEVER, from a roll......i think the m3 is WELL within reach. Remember the m3 isn't all that much lighter that the 6mt.

m3: 3415 lbs.
cls: 3446-50lbs(lightrims)=3396lbs

 

do you know how much a stock M3 dyno? is it close to 300 HP?


And actually you are saying the same thing that I am saying...

 

Man I don't know, that would be a tough race!!! but anything is possible!

 

i agree but just keep a small 75 shot just in case

sidemarker

 

The blown CL-S won't match the horsepower #'s of the M3 (333 vs. what, 315?) and tires and wheels would definitely make a difference. Supercharged, with headers and exhaust, sticky tires with light weight wheels, the CL would give the M3 a run for it's money. But for me, forget spending $4-6K including installation for a SC that won't give you the horsepower at the flick of the switch like a 75 shot of happy gas. I can't wait to take on the M3 next spring, when my system is on, along with some headers--pushing 355-375 horses! yeehaw!

 

Ive seen an M5 and M3 dyno in person and they dont put the numbers everyone is expecting. The M5 put 363hp to the wheels (395hp advertised) and the M3 put 312hp to the wheels (333hp advertised). Not saying that our cars put 260hp as advertised, hell we dont even do that with the I/H/E. Anyways, I think it would be a good race, one that a blown CL could win, from a roll. I dont think our CL's get out of the hole quick enough to catch the rear wheel drive. That's my opinion, i could be wrong, but i'll let you guys you in about a month when i get my charger

 

The CL-S S/C'd would win. If you drove it right. Come on... the M3 isn't that much faster right now to begin with!! Yes, you'd have some traction problems off the line... but cure that with good tires and a good launch.

Even the M5 isn't that quick in 4th gear. I ran it with my NSX with ONLY exhaust and I would pull in 4th gear (slowly, but surely). The CL-S isn't that far behind... will actually be ahead with the S/C.

 

I'm not sure, but it would give a good run for the money.

 

those horsepower ratings from the factory are at the crankshaft aren't they? Naturally, they are less at the wheels and will always be.

 

Come on people lets not start talking about if the moon were so bright and if the east wind were blowing at 5mph.

m5 isn't that fast in 4th gear and the m3 only dyno's 315hp at the wheels? I must respectfully disgree.

Remember even the s/c cls i only putting like 280hp to the ground.

 

A S/C 6spd will put over 280 whp... didn't the Comptech test-car put 305+ or something like that. It's pretty ridiculous if the S/C version woult put less than 300 whp!

Forget it then... the CL-S (S/C) will lose to the M3!

 

the m3 has 333 flywheel horsepower not wheel horsepower, so figure 20% loss m3 has about 295-305 to the wheels. But you also have to consider rwd, smg or stick, convertible/hardtop, a lotta factors......if you put the charged cls 6spd against an smg m3 convertible we should definitely take that....a stick hardtop would be a little harder

 

My apologies, you are correct the dyno is 315 whp for the S/C CLS. I think the race would be close. The CLS wouldn't get thrashed......

 

hey guys i started this thread and i like all the input.well comptech sais 315 at wheels but we all know front wheel drive has huge torque steer but with the right tires i really think its a close race driver vs driver.i mean m3 are really fast but alot had to do with the driver,how you launch the car,granted m3 has rear wheel which gives it the jump off the line but i think with the blower you have alot of power on the top end in vtec range so beating the m3 really could be possible. ill tell you this when i get the blower put on theres a kid in my town with an m3 and he wants to race me,ill post the results after the race with you guys:P :P also i just like to say thanx to everyone here for all their input about our cars and the helpful tips you guys provide!!!!!!!!!!!!!!!1

 

BMWs always seem to be much quicker than the published H.P. The 330 is a good example, upper 5s low 6s with 220 ?

 

even with the s/c i dont see the cl hanging w/ the m3

 

Why not ???

 

actually, the SMG is better faster than a stick, it's not a tiptronic like our sportshift, it's pressured from what i've heard...

 

that is true.

Nick

 

Yes, the SMG shifts faster than a 6 speed, but it has been proven, in magazines of course, that when drag racing from 0 to 1320', the 6 speed gets there a couple tenths quicker, because you can't launch it like you can a manual with 3 pedals. But if you were doing it from a roll, then the SMG may be just a hair quicker than the 6 speed.

 

I've never seen a 330Ci with 5.x numbers. You've seen this?

 

S/C CL-S! Amazing ... when I first bought my 2001 CL-S (November of 2000?), the only modifications available out there was CAI, exhaust, and probably some body kit.

Well, I can tell you guys from personal experience that M3 is a heck lot faster than the CL-S. My CL-S, stock, always seem to have hit a barrier everytime it reaches 100-110. 1/4 mile / red-light racing is never impressive either.

Contradicting what was mentioned above, the SMGII M3 is slower in the 1/4 mile. However, if the same 1/4 mile race is repeated 10 times, the SMGII would end up w/ a better average. Performance vs. consistency. SMGII is definitely better for track though, there's a video out there w/ a SMGII and 6M M3 racing on the Nurburgring, the SMGII had to hit it's brakes at one turn because the 6M missed a shift. SMGII always shifts perfectly.

Yes, from what I've heard, BMW tend to under-estimate their vehicles when posting numbers. Reversed for Mercedes.

SMGII is a true 6 speed manaul w/ a robotic clutch. Shifts in the most aggressive logic mode can occur in around .8 seconds. That's faster than the F1 tranny in Ferrari 360 and 575Ms.

M3 measures 333 (US) at the crank and w/ around 10-15% power lost at the wheels (283HP?). The transmission is very efficient.

 

Another thing ...

If the S/C CL-S manages to beat the M3 in 1/4, I can promise you guys that the M3 will still whoop the CL-S on a track (any track).

Also ... beating a STOCK M3 w/ a MODDED CL-S by barely milli-seconds ... doesn't make the CL-S seem that impressive?

 

No it isn't......... SMG times have always run slower than stick times. Of course if you hve somebody who isn't experienced then the SMG times will be faster but experience driver skill accounted for.....MT is faster than SMG.

 

I think the drastic price tag discrepancy and *status* of the new M3's alone would make a 1/4 mile victory impressive.

 

The price issue always seems to come up!

Actually, if you do a performance per price comparision, the CL-S has already won over the M3.

 

I like having an upgrade option for my CL-S that will help me compete with a car that I want but can't afford.

Yet.

 

either way, it'll be one heckuva race to watch!!!

 

20% of 333 leaves only 266 HP to the wheel. S/C CL-S would be a close race with the M3. BMW doesn't need much HP to be fast look at the 330 with only 225 HP with similar 1/4 times than us.

 

Also considering that the M3 is one of the best sports car you can buy out there. Overall performance you cant get better than the M3 I think its better than the NSX. Cl-S beating an M3 is pretty fucking cool to me.

 

I fully respect that! Drive safely but fast! Enjoy the CL-S, it's a beautiful car!

 

I spend alot of time on BMW forums. From what i have seen there is no E46 M3 that did put more than 300RWHP stock!!! Most M3's do put down around 275-285RWHP stock. With a Chip, catback and intake they do get around 300-310RWHP Max. But most Stock M3's are running very good times for the power they have which is low to mid 13's- at 106mph, few high 12's. Gearing on the M3 is almost perfect which makes the car pulls every pony it has under the hood and hook it to the ground. What do u think a SC CLS will get in the 1/4mile at what traps? I would say the SC CLS will have a better chance against a Auto LS1 with 2.73 gears than a M3 or even the C32. I dont think it will be that easy to beat a E46 M3 with a SC CLS unless he is a bad driver.

 

Take the S/C Acura up to the mountains, and pick out a M3 user. Then walk away from him, and let him beat the steering wheel swearing at ya.

 

as far as bang for your buck the 6 speed CL-S with the Comptech S/C would be your best buy but personally on a 1/4 mile track I think the M3 would win sorry guys but who knows I might be wrong

 

I think the CLS would take the M3 in the quarter mile s/c'd with much better tires.

However, to catch up in the track, you'd seriously have to work on the suspension to get it up to par. More specifically, it needs serious coilovers, lighter wheels, and a more heel-toe friendly pedal arrangement (I always slip when I'm heel-toeing).

But even with the s/c, coilovers, wheels/tires (6k,2k,2k = 10k) you'd still end up much lower than the price of the M3, without the warranty of course.

 

Haha...the idiocy in this thread bemused me.

 

The M3 runs a 13.3 stock. and your saying what?
