e85 or stay with pump gas

My engine builder asked if I wanted to "Go there" on my last engine. I declined. He did make a good argument for it. I was just not at that level. The car gets used a bit. I'm not sure I'd say often though. It is also aluminum headed at 10-1.

When I get to the heavy hitter for the Duster, I'm seriously considering it. Fully ported heads, cam duration in excess of [email protected], high stall, low gear, low car weight, etc....

Some of the things I like about it you can use more compression with the higher octane rating. More squeeze is more power. This would help offset the lower BTU return on the fuel.

At 10.5-1 ratio, you could use the fuel but I believe you could use another 2pts. of compression to really enjoy it. As well as get the most out of it. A helpful edge on the lower BTU fuel.

On the cooler running side of it, that's a win win in the heat of the day. Iceing can be an issue? I don't know how much. I don't remember hearing a lot of complaining about it. But a cooler running engine.....
