Disappointing ETs, and met 1MEANZ
With the drivibility of my exp large MAF working great, I feel very disappointed however, in my ETs where a 12.35sec was the best, the trap speed was 109.73mph. Last October, I managed to turn a 12.12sec ET. Of course the temps are a big issue here with 85*F temps tonite, while I had 45*F temps last October.
Also, of interest was my comparison between MT ET Streets that I have been running for 5 years very sparenly and my new P295/35R18 BFG Drag Radials. The 60' times are nearly identical. However, I think the Drag Radials were more constant, and the ETs are a bit touchy.
And I met 1MEANZ at Milan today, he has his car running very good.

The "air" can make a big differance in times. Sounds about right to me compared to your last time out.
I will be going to the track in two weeks with similiar horsepower numbers. Maybe I can get into the 12.2's using your numbers.

Yea, Doc two tenths is not so bad considering the added 40* in temp. BTW, what pressure are you running in the ET Streets? I had the same issue, going from a drag radial, to the ET Streets, and found the ET Streets liked more air pressure.
