What am I doing wrong at the track?

[Mad Max]

03 Cobra. Ported Eaton, stock rear end, Nittio DR's.

Speed in 1/4 was 121 - best time I could manage was a 12.0 (by looking at the mph, car should be upper/mid 11's).
Best 60 ft. was 1.7....shifting at 5900 rpm. Lauched around 3K.

Any sugestions?

Judging by the mph, yea, you should be mid to high 11's but sometimes it all depends on how they are prepping the track on the day/night you run and how the weather is. Try goin on a day or night that the track is cool and dry and you should be able to get into the 11's.

I have the same combo as you. I ran an 11.66 @ 121 with a 1.85 shorttime. somthing is not adding up. thats alot of mph and a good shorttime

Hmm, maybe try shifting around 6500?

shift at a much higher rpm. those cars are designed to pull all the way to the rev limiter. I was under the impression that the mph will take the et to low to mid 11s. maybe 11.3-11.5. is that way wrong? does someone have vids of those mph and et's so I can get it right.

That seems about right. 1.85 is a "ok" 60ft for a DR tire. Plus w/ IRS too boot. I've seen guys run 11.0's to 11.40's with 121mph but with a 1.4-1.5 60ft. It's all in the launch. I trap a measly 112mph but run 12 flat. But it's all my 60ft that makes it happen (1.57). -Mark

I agree with the above posts, your trap speed is mid-low 11s, so id say shift at a higher RPM. that should help bring your times down. Your 60' is good.
