You can run alot more timing with E85, hence the power gains that you see. And where 14.7:1 is stoich on regular gasoline, it is only 9.765:1 on E85. It also lacks the protective coating that regular gas provides to prevent corrosion from water and air. So unless he is highly boosted, I would stay away from it.

Most stock B16 swaps make around 135-145 whp on our dyno. By making the switch to E85, we were able to run a good bit more ignition timing, and the results are good. We were able to make up for most of the power lost through the drive train. On this pull, we stopped at 7600 RPM, because power was dropping off, and there was no reason to keep going.

My boy sent me a link 2 a ht where they said they got good ganes from e85 on a stock b 16 we ran the # and he will wast about 400 to 450 converting 2 e85 and geting a tune u think it's worth it ?

was that $400-$450 a year? regardless you are going to spend that on your tune anyways and corn oil is notorious for killing fuel systems

agreed.

It is not worth it on a stock motor at all. Or even a slightly modded one at that. Yes it allows you to run more timing like I said before, but at what cost? Slowly killing fuel system components, losing around 30% fuel economy, and once tuned you will have to continue running the e85 because the tunes are so drastically different you risk damaging the motor if you decide to put regular gas back in it. Unless you get it retuned again for pump gas of course.

In a nutshell it may be cheaper at the pump, but all of the other cost factors outweigh that.
