0-60 acceleration on C230 K, losin all the time :)
Hey, I was just wondering if maybe im having a performance problem with my car or soemthing. But im consistently losing to everything I race. I have an auto 02 C230.
I just launch by flooring it off the line, no esp is cutting in, its just bein slow.
So far I lost to a V6 explorer, a regular cherokee and a nissan pathfinder 3.5 V6 which is 240 hp.
It seems the SUV's always want to race lol. My car just seems to lag off the line, like its dead then picks up heavy from 3000 rpm.
I have the Remus twin exhaust, not sure if this is causin a loss on my LOW END torque?
Thanks alot, just wonderin if that lag is normal

I would say 3K-3.5K rpm just enough for the wheels to spin a bit.. some people will say you will damage your tranny... but if you are not doing every single traffic light.. I think it's going to be fine.

Someone I know went from 18" to 19" wheels and lost 9 rwhp on the dyno. The problem with 19" wheels is not only weight (and don't underestimate the driveline losses from extra rotational mass), but the tires have a bigger diameter effectively lowering your gear ratio.
If it makes you feel better, I raced an Acura NSX, 252 HP and about 100 lbs. lighter than the coupe (except he had a passenger and I was alone) and I held my own, neck and neck until he gave up because he had to make turn. He might have had more HP but I have more torque throughout the power band. We wasn't happy.

95% of the cars out there can accelerate to 60mph with 2nd gear
the coupe need to shift to 3rd
it takes some skill to launch a manual car while those autobox SUV u just stomp on gas and they designed to have some low-end power so you can haul stuff
40-120mph is where the coupe shine

The C320 sedan reviews in magazines typically get 0-60 times of 6.9 seconds for the C320. I get C320 loaners all the time and it's considerably faster than a stock coupe.

I even lost to my own clk 320 convertible. That is supposed to have a 7.7 0-60 but that 320 has low end power. My c230 just seems to have NO low end. Im starting to suspect my REMUS muffler. Maybe it causes a loss in low end power.
Buell, did the renntech cause a loss of power for your car? Maybe its the design of these cans? And when you ran no muffler on the dyno was your 6 hp gain only at top end, and was low end power lost? Since our cars are supercharged, we still need backpressure, and I hope my exhaust isnt the reason for the dea pedal off the line.

Wow that's weird... i've beaten a new pathfinder before.... and other SUV's off the line.... i think the C230K has great off the line power.. well not SLK32 great... but good enough... i hope you're torque loading before you launch and turning ESP off does help for me....

Whats the best way to torque load?
I never tried that, I just mash the gas from a stop. Maybe thats the problem?? Who knew lol
Explain the process if possible. I can brake stand it by slamming the brake pedal, then mashing the gas, but it peels out while standing still.
My continental tires were gone after 5000 miles, i rip it!

the way I torque load is left Foot on the brake... right foot on gas pedal... get it up to 2000 to 3000 rpm.... ESP OFF... just try not to spin the wheels.... and when the light turns green.... let go of left foot and smash on the accelerator... it jerks the car forward, feels like you're abusing the tranny which you are... just don't do it too much...
I remember someone... i forget who.. mattc230k??... i forget.... he said leave the touchshift at 1st gear and step on the accelerator... the computer should up shift for you.... i haven't tried this yet...

Yeah, it upshifts way too late tho with it in first. Like way after redline on my car.
If you really want to have a chirping shift from 1-2 i have a method. Floor it till about 5900 rpm, totally let go of the gas, then smash back down on it, this has to be done really quick, and your tranny will kick SO hard into the next gear, it causes my esp lite to go on, I think this is bad for it, cuz sometimes when I do it, it bucks and jerks but switches so much quicker. The whole car lunges foward when it shifts like ur powershifting a manny.
I can even get the esp lite on, thats how I know im losing traction. Quite impressive for an auto IMO.

You know what of my favorite thing to do with my car is... i love flooring it right after i finish gassing up.... the engine is extremely loud.... louder than usual... you should try it sometime... ![Big Grin](https://mbworld.org/forums/images/smilies/biggrin.gif)

As for that other method, it does sound hard on the tranny. And as fast as it feels like it is shifting, you are still losing time. Any time you lift or chirp the tires, you are losing time.

Yeah it has a really raspy tone to it. I love that, and the remus helps out even more. I got a set of 19's for my car but with the NJ/NY road conditions near me, im thinking of selling them. Plus the car doesnt feel that fast., im gunna try that brake launch later today.
I am thinking of a pulley, but will that help out low end??

2002 C230 Coupe
Has anyone raced a M3 before?
When I was going to lunch today, there was one pre-2000 M3 tailgating me for several lights (a 2 lane 2 way steet). I was so annoyed that at a light I floored the gas and went. I could hold him up until the --------- 3rd gear hahaaaa! First time in my life went above 80mph on a 35 zone street.
I guess he was pissed too because when I smashed the brake at the next red light he pulled over to the left-turn lane and flew straight through the red. I think he was over 100mph.

2. Any dual exhaust on an I4 will cause loss, so your Remus is robbing you of some power.
3. Why are you racing everyone? You have a Benz, roll the windows down or peel the glass roof back and cruise.

Some coupes had cam timing set wrong from the factory and where only able to get in the 150-160 rwhp range in stock form.
