C63mx

Hello, I am new, my name is Carlos and I am from Mexico, I have a C63 2010 without modifications, only has filters k & n and rims nitto invo.

I tried it in the quarter mile and I was disappointed in the time, 14.2XX - 14.5XX constantly, I am at 1600 meters above sea level, the track is good, do not skid, I put it in "S" and deactivate both controls Of traction.

what I am doing wrong? Is there something I have to modd of the car?

Thank !

Look up "altitude conversion factors". At roughly 5250', you'd subtract a second to get to your sea-level ET. 13.20 still seems slow for a stock car, but it could be anything.

As BLKROKT said, you conversion factor is .9341 because you live a mile above sea level, so that is a second of your time. Would need to see your timing slip to see if it is your reaction/60' time or if it is something else.

Dude how much are these things in Mexico and can you tell us what kind of industry you're in??

That should sort it out.

Get drag radials or stickier rear tires and wheels as well. Aside from altitude wheel spin will be a lot of your problem, especially with LTHs and a tune.

Do you have the MPH as well as ET?
