he didnt take it to the track, but he increased the boost on his turbo diesel. i am not sure what he was running, but he put it in 4wd hi..and we raced from a start. he said he 'dropped' it at 2k rpm (they have like a 4500 or 5k redline i think) ..and all i heard was tires spinning...freaked me out. the four tire marks looked pretty freaking cool.
