There was two guys spraying there cars local to me. One had 125 shot i saw him make at least 30 passes never had any trouble he ran 10.70's @ 125.
The other guy had 150 with race gas. Never ran better than 10.88. last time he took it to the track he blew a window in the block . He broke the a rod in half and it slaped the valve and did whole lot of damage. Best advice if you going to spray get you a A/F guage and a good tune.
wow im guessing trying too much timing? My plans are a 150 shot but dam thats scary.. who tuned the car?
