Can Anyone Explain this?

Stock- I went to the drag strip that is 1/8th mile long. My very first run I ran 8.6.

CAI, BBK Shorty Headers, Electric Cutouts- I ran with headers closed and off. My best was 8.8. A few months later which is today my best time was 9.0 flat. How in the world is my car slower than stock?

Can anyone explain this?

Air quality sucked I am sure.
What was your 60 ft time on the 8.8?
Lot of things can do it.

As mentioned.
You need to compare DA (Density Altitude) of each track day. Warmer and more humid weather really slow these cars down.

Also - look at your 60' time to see if your hooking up as well. Trap speed would also indicate your power level.


But my guess is the weather was considerably cooler the day you ran your faster time.

Well it wasn't a popular drag strip and their computer was broken. I just happened to see my times as I passed the board. But it should not matter as I was sweating balls when I ran the 8.6 and it was just 85 degrees and humid last night

As mentioned in another thread, it could be wheel spin.... if you are not used to the extra power due to the mods, you might not be putting that power down properly.

Depending on your tires, if you have heated them up several times, they get harder and harder with every heat cycle. So you could be having a little issue there as well.

Track prep plays a huge roll. Probably spun more than before
