I had some Subaru take off like a bat outa hell from the light tonight. I guess he saw my license plate, 1FSTDSL. Unaware he wanted to race, I caught up with him and rolled down my window and asked if he would like to try that again. I flipped on the propane and comp box and all he saw was tailights and lots of smoke. I slowed down and he asked what I had running through that thing, I said its just a diesel. I think these things are supposed to do the 1/4 in the mid 13's.
