E30 vs MS109

Does anyone know how much more power can be obtained with this fuel change? X37 and bolt ons.

i dont forsee a huge difference. While MS109 has higher octane, the ethanol in the e30 will help it burn cooler, lowering cylinder temperatures, which is similar to increasing octane (allowing more timing). Factoring in $$$$, e30 is a better bet.

Thanks. I have a E30 tune but I'm attending a 1/2 mile event for fun and a buddy was asking me since he is bringing extra MS109. I didn't want to hassle my tuner for a new tune for mediocre results. $$$$. Thanks for the input.

You could add more timing and boost. Don't know for sure how much more power but without and updated tune for it your not gonna get a huge gain.
