Hey guys... going to the strip with some friends tomorrow night. What have you found for the quickest times? Keep the car in S or M?

My Car is a C63 P31

Any other suggestions?

Thanks,
Dave

Manual ONLY

i practiced in manual but dang it's hard to get the timing down...

SCCAForums

Thanks!

Try S and paddle it down to S1. It is then supposed to shift at red line. Roll into it because if you hit it too hard and get spinning too much it might hit the limiter and the car will bog out before it shifts to second. ESP off. I am not a racer just going from what I have read.

Manual for the best times.

try them both and see what you like the best. i would probably go with s first and then m

mthis

M is the way to go. Will take u a few runs to get it down rite but once u do its worth it.

SCCAForums

Thanks Guys... tried both ways.. seems like a 1/4 of a mph better in Manual mode... ET relatively the same... both 12.2 @ 115+... 1800 DA here in AZ.

I was only able to get 1.9 60's no matter what I tried... any advice on launch techniques?

Thanks,
Dave

Get drag radials.

SCCAForums

I do have Drag Radials! 18's...

It wasn't wheel spin... just seemed to almost bog a bit?

What pressures do you recommend? and What stall rpm?

Thanks!
Dave

I use S+ but from the sounds of it you are pre-facelift so my drag methods would be slightly different..

propain

1800-2000 seemed to be the sweet spot. 20psi to start. All depends on the prep.

SCCAForums

ok, thanks! I'll try that next time.

SCCA Are you running out at Firebird? Shoot me a PM if you are heading out again. I live 10 minutes from the track and would love to see a few runs. I am not ready to put mine on the track quite yet, still learning.

I am contemplating getting out in January when they have some of the events for NASA/SCCA on the race track.

SCCAForums

Hi SunSpot... yup.. ran at Firebird... we will head to Speedworld New Years Eve... you should come!

I'll PM you next time.

Find cooler air

HAHA.. ain't that the truth!! AZ is not the best place for the strip... that's for sure!

Thanks again!

Your times are about right.

I was getting 1.78 60s with drag tires, headers, tune. Car is heavy and your DA isn't the best, but it's better than ours here at 3000+.

Dave,
I assume your car is a 2011 or earlier. Start off in "S" mode and let the ECU make the 1-2 and 2-3 shifts. Then change to "M" and hold 3rd as long as possible before the rev limiter. Unless you have the opportunity to practice a TON with the 1-2 and 2-3 the ECU will outperform you every time. However, the 3-4 is far enough out you can handle it.

I find my best times are from 1000-1200 stall. Mash the pedal just before you release the brake. Not simultaneaously.

Good luck and be safe!

Thanks guys! And Dad's... you're right... on most my runs I either shifted too late to 2nd (first pass) or too early... and it would shift at 6K or 6,500... so that sounds right... I was fine on 2-3, 3-4 And noticed when in S mode... the 3-4 shift wasn't as solid as the M mode.

So that's a good compromise.

Thanks,
Dave

Manual will get you better ET if you can master the shift out of 1st without redlining.
