Cobb Accessport Quarter Mile time
Hey all, I ran my 08 135i at the strip tonight. I am completely stock except for the Cobb stage 1 tune, version 2.02 standard throttle mapping. I had a hell of a time getting the factory run flats to hook up, hence the horrible times. I was stoked about the mph though. Shows the car is making decent power for just a simple tune. I need new tires and I need to work on my lauch, and no doubt this car is capable of 12's. I'm coming from a Subaru STi, so the launch is a bit different. I was spinning into third. Here is a pic of my time slip, I'm car 140.

Nice! With that mph, you should be doing a 12.8ish 1/4mile.

Thanks man! I know, maybe even quicker, I just couldn't hook up. I was having the problem of spinning all the way through second and then sometimes bogging into third, because I wasn't going fast enough, then losing traction a bit at the top of third. Need to work on my launches too. My best 60' was like 2.1.

.7 is a nice reaction time. Better than the 1.2-1.6's i've seen sometimes. Definetly ditch the RFT's!

Thanks, but wasn't too worried about the RT, as it doesn't affect your quarter mile time. I was trying to concentrate on my launch, maybe a little too much! Car is making good power though! Thanks Cobb!

Nice!! Thanks for sharing, yeah I am stuck at 13.5 104mph best stock w/ a 2.0 60' a couple times on OEM RFT. Deft around 2k rpm launch is tough, either bog or spin hard, fine line for sure on these tires.
Great mph for sure!!!

I ran a 12.5 at 111 with Cobb stage 1 and a 2.0 60ft and a 12.7 at 114 with a 2.2 60ft. Definitely work on your launch, feather the clutch like you would from a stoplight only faster, don't just drop it. Try different shift points as well, 6500 is a good place to start. Run flats gotta go.

Thanks for the advice. Just gotta get used to a rear wheel drive car again. I had the same problems with my Mustang back in the day, without the rock hard run flats to compound it. Yeah, I was launching around 2k, feathering the clutch but it just wants to let loose. The track prep there is iffy, especially for street tires. I am used to 1.8 60ft times with my STi, but I love the challenge of this car. So much fun. |

You'll see once you reduce your 60ft, your trap is going to reduce, but you'll obviously improve your ET which is what counts in a drag race anyways. |
