I saw one race a couple weeks ago, not sure if it was Tx, or No Problem La. they were running i 10.20's brk. and the kid broke a line ir hose and ran the full length of the track, with white smoke boiling out from under the car. It was antifreeze, and Rich had him up in the tower i think that was the race that the guy was banned for 2 yrs.. The kid said i didn't see it because i didn't look in the mirror, that's when Rich called him out for running antifreeze. I can tell you that antifreeze and synthetic oil are the 2 hardest products to get off the track. NHRA and IHRA will also ban you from a race if you put antifreeze on the track. Some of the tracks around here look at the cooling system to see if you have antifreeze and if you do you will not be able too run until it's gone. Too me this is something that's hard to police because they allow street vehicles to race and even have their own class.It's a catch 22.
I personally wouldn't go to a pinks event if they paid me in and bought the gas to get there.
