I took the C63 to the drag strip for the first time. I had 3/4 of tank with 91oct in it(that is what they sell here in AZ). I also weighted the car by it self on the scale and it was 3964lbs (with about 40lbs of my own camera gear, helmet, jacket, etc) I weight 200lbs. Car has 6100 miles as we speak.

I only ran 3 times:

First run
60ft 2.073
1/8 mile 8.6@83.86
1/4 mile 13.256@108.45

Second run
60ft 2.064
1/8 mile 8.591@84.79
1/4 mile 13.164@108.97


Third run
60ft 2.068
1/8 mile 8.621
1/4 mile 13.229 @108.28

This track is at 3100ft altitude and there was a lot of crosswind. I didn't even bother to mess around with tire pressures or none of that. Next time I will take the car with less weight and less gas. The only mod I have is a pair of K&Ns. I was expecting a 13.0 flat at this track and speeds of around 109-111mph. Speaking of times, my buddy took his Lexus ISF and ran a 13.9@104 with a passenger

Any ways, that was my share.

Just out of curiosity, how are your rears after 6100 miles? Did they hook up okay?

mthis

once your car gets over 10k then you will be faster.

The rears were actually new. I just got a set of 275 Nitto 555 S like 500 miles ago. The first oem set were bald by 5600 miles.

I am not sure about that. I heard that before but I think is a combo of bad 60ft, altitude and lots of extra weight. I think I could get a 12.9and a 110mph if I drive to Phoenix with less fuel and less stuff inside(no spare, no helmet, no extra camera stuff, etc)

mthis

you will deff hit 12's that for sure but im saying once you hit 10k and more you will be in the mid 12's at least that what happened to me when my car was stock.

p:s you should order ms109 race gas and mix it with you 91 oct and that will get you moving a bit. im sure if i had my car stock and i used race gas i would beat my best stock time. 12.168 at 115.82...

Which track were you running and what time of the day?

C63newdude

Southwest International Raceway(Tucson, AZ) 3100ft. Daytime at around low 60 degrees.

Dads C63

According to the DA corrections you would have run 12.6 or 12.7. Congrats and welcome to the racing life!! Its a blast and very fast!! ENJOY and be safe.

Some better tires will get those 60s down and you into the 12s easy. Should be able to do 1.8 or so.

I don't know if this is relevant to any but took the car again a few months back but never updated my signature. I ran 12.9@110.5 with the addition of better gas (some 100 octane mixed) and K&N filters. I ran 12.9 several times by the way..

When I do the altitude conversion it comes up to around 12.5@114-115mph so it is right on the spot. I am at 3100 ft elevation.
