Went to the local 1/4 mile last night, here in tx so it was hot and humid. The beat I did was a 12.88 @110....all three runs I was at 110 between 12.88 and 12.96. With 2.1 60 ft. 8.4 in the eighth @ 87 mph. I thought our cars were supposed to trap 120ish and do 12.2ish? I have k&n's and Eurocharged box tune. It was long waiting in the line to run so I'm wondering if the iats were so high that by the middle of the run the S/c shut off maybe or pulling timing way out?? I forgot to take my obd scanner to log with. I did replace the intercooler pump when I got the car 3 years/20k miles ago with the Bosch 010.....anything sound way off to you guys?

What was the temperature at the track? Do you have a better aftermarket heat Exchanger and pump? There are a lot of factors that can make your numbers not as good as you would think. 12.88 is still a respectable number to put down.

It was about 85 degrees and high humidity. Stock exchanger since car is completely stock except tune

85 and high humidity is going to play a big factor. I would get a better exchanger and pump. Look at a belt wrap kit for your SC belt. Those are the things I would start with.

I would wait until the temp drops 20 degrees then go back out with some drag radials

Stock e55s do not trap 120.

A normal e55, at a normal track with a normal DA is 112-114.
