A friend asked me the other day what all I had done to my car. I gave the standard list which got me thinking about something i put together a long time ago. This is a list of mods (from time i bought the car) and what they translated to at the track. All runs were done at Royal Purple Raceway in Baytown, TX (formerly Houston Raceway Park) at all different times of year (i wish i had weather conditions logged). It's cool to sit back and see how far you've come.

** Analyzing the runs on this day, I found I was losing quite a bit on the top end compared to other recent slips before the stall. I later found when I had the TC installed, whoever put it back together connected one of the o2 sensors before screwing it in which twisted up the wire and pulled it apart. I replaced the o2 sensor and car has been running better since but due to several reasons, I've not been back to the track since 2012. Hopefully, soon the stars will align and I'll be able to get back to the track to see what the car can really do!
People looking to stay NA and wondering what certain things translate to at the track should be able to gleam some rough estimates from this. I only posted the best ETs for the given setup, not the dozens of others which weren't as good.
Before the DRs, the best times were had with launching around 1500 RPM.
Before the stall on DRs, the best times were had with launching around 1700 RPM.
With the stall, I was launching around 3000-3100 RPM.
Huge improvements in being able to heat the tires and launch without spin were had with the line locks. I wish i'd done those as soon as I got the ET Streets.
