So I race the stock predator class at Owosso Motorsports Park and Im slower than the others, it can't be the gearing because I ran a 16 67 and it should've been fine, last time I ran a 16 65 and it was fine, but before i Changed it to a 16 67 for the heats and features, I ran a 16 63 and a 16 65 and it was still slow, the 16 67 was also slow, the weight is fine, the tires have 7 lbs left side & 9 lbs right side. So at this point it has to be our motor, im thinking we need new valve springs because they got a shorter life span because we over-redlined our motor at Arthur Raceway our first race of the year, & im sholed we didn't blow a motor, but all day we redlined it that day from 6,700 to 6,200 at Arthur because we had a 12 66 and a 13 or 14 65 I think that day, at our second race of the year we were running perfect just a little loose. Im thinking the Jetting is wrong too because im running a 0.35 and last time before this last race at Owosso, I ran a 0.36 Jetting, we ran a 16 63 and 65 gearing that day, so im guessing it's either the Jetting or needs new valve springs.
