12.1 @117mph..that seems slow for a K2 car doesn't it?
the particulars:
3/4 tank of 100 octane - should've been 1/4
DR in rear @ 27 psi
Dyno mode
1.8 60'
miserable R/T
Track was dry and approx. 65 degrees.
Both me and KenE55 (stock, averaged around 12.5 @ 112)experienced better ET but lower mph than previous runs. Any ideas?

Indeed that does sound slow for a K2 car. Not too concerned with the et, simply because excessive wheel spin from too much power can cause ****ty e.t's. MPH should be upwards of 120 on a K2 car. MPH is a good indication of how much power your car is really making.

Drives Slowly
This may be BS but at the end of last year, right after I had K2 completed, I went to the track and ran low 12s @ 118 to 119. I was a little disappointed with this so I called Cory (at Kleemann) about my numbers. He told me that the computer adapts to your driving style and responds accordingly. So, that being the case I drove the living **** out of her for two weeks, returned to the track and trapped @ 122and 123mph on every run. Go figure.
So, my advise................. drive it hard for a couple of weeks and return to the track.

Why would a mix of octane perform better than only 100 octane? I understand the ecu adaptation issue and will "drive the living ****" out of the car until the next event. That ecu WILL know who its daddy is.
Incidentally, my first run (in the rain) was at 119mph. The car can get up there...I know it can.

I'm sure you could drive the **** out of it with 100 octane the whole time if you don't mind the $$$...

Do you have the upgraded cooling pump? If not, the extra boost could cause the heat exchanger to be taxed by the end of the run,..Hence you may see a tail off of Hp by the last part of the 1/4mi. run w/o realizing it.

You should be in the 11's with K2 and DR's. 117mph is not bad. 1.8 60' is not bad at all and should also facilitate 11's. Go to the track again for more runs. Make sure the car has been cooled (iced) before you run it. LSD?

I guess 117 is not that bad at all. I just ran my K2 tonight (80 degrees and 15 mph headwind) and ran 11.902 and 12.023 @ 116 and 117, respectively. Both runs 1.8x 60's.
Just driving it around compared to my C55K S7, the difference in power is night and day. I can't believe I ran such a bad time. It feels like it pulls so much harder than my C55K S7 (which ran a best e.t. of 11.9 @117 on 100 oct.).
Granted I didn't heat up the tires nor was I running 100 oct. The car definitely feels like it should trap 120+.... very strange. Heat and elevation maybe?
I had my car dynoed the other day and it's putting down 481 rwhp and 552 rwtq. Go figure... thought my et and traps would be better.

Last time I had the car at the strip best run was 12.02 at about 121 mph. It was friggin COLD and windy. It's definitely a 120 + car.
How's it running otherwise?
