I'm first! I really like the 178. I stacked the 178 with a 65 and ran the exact same 1/4 times. What I learned is the faster you spin the supercharger the more it takes to spin it. The trick is to hit the sweet spot where the extra spin gives results. People with 181's and 185's need to speak up and post mph in the 1/4.

I always have extra octane in the tank if I'm going racing. I consider it an insurance policy. 100/93 mix. For putting around any 93.
