Track times.

[Intrusive97gsx]

I went to the track last night and the results weren't even close to what I was expecting. Last week I was pulling 97.75mph in the 1/8 on pump gas and this week I'm only getting around 92mph. For some reason I was only getting around 11 degrees of timing when my AEM map normally pulls to around 19 degrees. It was pulling timing and adding fuel with the around the same amount of knock I normally have and I didn't change anything from last week. Because it was adding fuel I was running around 10.75:1 A/f instead of my usual 11.2:1 A/F, still haven't figured out what happened but I'm working on it.

I figured the EMS was just being a pain in the ass because on one run the car was sputtering the whole way down the track and when I tried to look at my log, it said that the file contained no data. Then I noticed my battery was REALLY low on the laptop so I shut it down and planned on calling it quits . After I unpluged the laptop I decided I'd give it one my shot... and the car ran fine (still wasn't running RIGHT, but wasn't sputtering). So here's a look at my messed up pump gas runs.

Here is the Time slip from last week at Fayetteville.

You must be logged in to view this image or video.

I think I fixed the problem with my 2-step which was causing serious knock issues, now if I can only get my 60' to be more consistant. A lot of places around here don't prep the track so that makes a huge difference in the results.

21psi
93 octane
Intake Temp 124 degrees fahrenheit
11.0:1 A/F ratio

The video from Fayetteville
The first run was when my AEM took a dump and was sputtering going down the track (listen to the first part second gear), so I let off after second and coasted down the track. The second run I started going sideway (can't see in video) and I missed second. If you listen you can tell that I was out of 2nd for a while, which really hurt my ET. The third video I ran okay with a 1.80 60 foot and some spinning along with slow shifting I ran a 12.1 @ 118.xx.... The worse part is we didn't get video of the (3) 11 second runs I made but atleast I got the slips . Anyways enjoy the video.

I'll be going to Rockingham tomorrow and hopefully try to get some low 11's on pump gas.
