NO I'm Sure cause it kept doing it over and over, my friend was tuning it for an hour trying to get ready for the race that day and found the sweet spot right at the line of popping.....we laughed for a while then realized what we were doing to the engine and decided it should probably be a little leaner on the bottom....
I bought a 50t Spur gear and was going to put the 12t CB on my OFNA to see if I could do it w/ gearing but I have yet to put the stuff on......even got the 13t pinions for the diffs....
