hey good point, totally forgot about this. I know on my 10.5 in 2wd buggy I retarded timing on the can, thinking it would make the motor run a little slower and cool it down, but it actually went in the opposite direstion. It make the motor run like crap and get hotter. I was running around 150 and after I went to 165. I went back to the stock 30 degree timing and bumped the epa back on the radio and dropped temps to 130 and still sun great lap times.
