work on launching

 

Yup your launch is pretty bad. I cant do better than a 2.1 because my clutch wont allow it and I ran 13.80@103.8. You should be in the high 12s for sure. It takes practice though and you'll get it. Drag racing is all about the 60' and the rest of the way takes little skill, you just shift. Practice makes perfect right? Good luck.

 

Yeah, that 2.36 60' is a big part of your problem. Get that down to a fairly respectable 2.15 and you should see about a 13.6-13.5. It's basically Summer so the weather isn't exactly great and that doesn't help either. Wait for cooler air and you should get another 2-3 tenths (possibly more) off your ET.


Your MPH is really low in the 1/8th but isn't too bad in the 1/4. Looks like your car is moving pretty good on the top end.

Pratice your launching and your ETs will start dropping.
