I went a couple of weeks ago before I put in my 80mm and chip and ran a 10.2 in an 1/8th mile track. Tomarrow a bunch of my military friends my roomates and me are going to race and I'm going to see how much it helped. Then in the next week I'm going to be installing my nitrous that I baught and see how much that helps I'm probably going to put in a 100hp shot in. Last time I raced I beat 4 out of the 5 people I raced loosing to an older VW Bug on crackthat beat me by 1 sec. in an 1/8th.
