So myself and a couple friends are heading out to the track tonight to do 1/4 mile times...

I have yet to try RS -- is it going to make a huge difference in my times if I don't use it?

Any input is appreciated.

Also -- if I am not using RS -- M vs S+?

Thanks

My best times at the track were when I used the following combo: drove around the water box, scrubbed the tires (not a full burnout) traction control in Sport handling mode and gear selector in S+ mode. Roll into the throttle off the line and have it mashed by the 60 foot mark with our glorious exhaust screamin'. This resulted in a 12.228 at 115.90mph bone stock with P31 pack.

Have fun out there because that's what its all about!

Thanks for the input.

So -- S+, traction control off and don't hammer it off the line?

jmueller

I used Sport handling mode for the traction control (we have three modes: on, sport, off). But If you mash it off the line in any mode you'll spin the tires and either traction control will cut in (if its on or in sport) or you'll just sit there and spin for a little bit (traction off). That's why you should roll into the throttle.

If you have the opportunity, give race start a try. You're on a track, and you paid to be there, so take advantage of it! It just didn't yield my best times.

why does it sound like the windows are open?

jmueller

Because the windows were open.

(It was very hot outside and the track was privately rented, so they really didn't mind us having the windows open, nor were they enforcing the helmet rule (still rocked mine though)).

Good run jmueller, will have to link up sometime and hit the track together!

jmueller

Would love to! I'm getting Mike's Power Pipe put on tomorrow. Looking forward to seeing if it makes any difference on the track (unlikely, but can't knock it till you try it).

So I made a few runs last night -- best I could do was 12.89

I have some work to do.

damn 12.2 stock? I guess normal is 12.3-ish...I guess tuned C63s are running high 11's?

jmueller

Not sure exactly what other stock cars are running, everyone that was there was pretty astonished though. I was as well. I was expecting 12.5 or so. I also have the factory limited slip diff which helps out the power down better. I guess F. De Guisseppe built one hell of an engine for my car.

@jmueller.... thats the same amg mech that did mine...... serious knock on wood....

jmueller

Why knock on wood? Did he not do such a great job for you?

nkc

Arrghh d very opposite , tryin to say he did such a good job, zero challenge as regards engine performance ....

jmueller

Ahh got ya. "Knock on wood" typically means that one of us isn't having a good time and you're hoping the problems don't transfer over, so I was a little thrown off.

nkc

Arghhh my bad..... Lol

New to the C63 world but Road andTrack says their best time was without RS using the break and feathering the throttle off the line. Have not tried it yet. Still getting used to the car.

That's the Italian who built my engine also!
Going to have to go to the track and see what my non-P31 does bone stock!
