there are two types of people who make their cars waaaay faster than they should be for racing.
one is the basher that is first trying their hand at racing and soon realizes that in order to actually get around the track they need to slow down their cars a lot.
the other one is the problem, you know the guys that have been racing for a while and run 1/10 mod truck or buggy or even more scary still 4w buggy and they cant put togther back to back laps without wrecking 5 times. then they come off the drivers stand and say they need more motor
. those guys will always have way more power than their skills will ever be able to control.
instead of limiting the power output all a race director needs to do is say you must be able to maintain a reasonable ammount of control or you cannot race or even practice. i have no problem with new guys learning and wrecking as long as they keep the speed down and arent punching it all the time.
