You cannot simply pour in a different fuel and expect to go faster.


C-25 has a faster burn rate. It requires less timing, etc, than C-12, C-14, etc. It also requires a different A/F ratio. And it won't necessarily automatically generate the same or the correct A/F ratio for your engine. It will require serious tuning. It probably won't do anything for a lower compression (below 11.5:1) engine.
