First time at the track!

Well, was out at the track 2 weekends ago (finally getting around to posting this here, damn 60 hour work weeks). Had a LOT of fun, and the car ran really good on the 110 octane that I threw in. Here's a quick run down of my setup and the times of the 4 runs. Let's hear your thoughts!
