raced sunday no pinging ran 1.5 110 oct. 3.5 93, temp 78, track was wet, never heard a ping. also the modiefications really added some nice power, she definetly pulls harder, and revs out better. about a dozen quads on the line mostly 450s about 100 yards to the turn I pulled third. am still going to try a cooler plug for hotter weather will every one know. thanks for all the input and advice. bill
