Just got back from the track tonight. This was probably the last time I'll have the opportunity go in the car's current configuration, and I wanted to see exactly what kind of gain I'd get from the AIS Meth kit I installed a few weeks ago.
The setup:
-COMPLETELY full street trim. Left the street tires on, and didn't take anything out of the car. Still had my books and lunchbox from school today in the trunk, haha.
-AIS meth kit with single 7 GPH (440 ml/min) nozzle (way too big). I was using windshield washer fluid, which is 30% methanol and 70% water.
-I adjusted the tune the best I could with my SCT programmer. I was able to add 4 degrees of timing before I heard any detonation. I also leaned out the WOT AFR as much as I could with the programmer. With the meth, it was still 10.2-10.5.
-1500 feet DA at a VERY slow track. New 5.0s were only trapping 105-106, and everyone I talked to said their trap speeds and ETs were down 4-5 mph and .3-.4 seconds from what they normally run. The track had problems with the timing system early in the night, so it wouldn't surprise me at all if it wasn't calibrated correctly. I know that my speedo indicated over 110 on every one of my runs, but my best trap was only 106.
I randomly picked if I ran the meth or not on a particular run, but I made sure that I had at least a couple of runs of each type with a good cool-down, and a couple of hot-lap runs.
The best run without the meth was a 13.44 @ 103.2 mph. The best run with the meth was a 13.21 @ 106.1 mph. Both runs had a 60' of 2.01. On average, I trapped 2.4 mph faster with the methanol! Considering the weight of my car (probably 3700+ tonight), I'd estimate that that's at least 25 rwhp, which I think is very impressive with no dyno tune.
To say that I'm happy is an understatement!
