At that boost level, running c16 is the equivalent of wearing 2 condoms. It’s $3-4 more expensive then 110 leaded fuel, and you’ll make more power on it. Really at 250, that’s still in the realm of pump fuel.
If I built the bike I would of built the motor when it was out. but I bought the bike this way. just want to make it work for this summer. this winter I plan on doing the motor so I can get it over the 300 whp mark
