Considering investigating whether a 2010 SS could be converted to use E-85. Any thoughts? Or has anyone already converted?

 

You can give ZZPerformance a try. I believe they have a Cobalt SS/TC they converted.

 

The only 'conversion' at this point is a change in the tune. There have been a couple people run E85 on stock lnf's with good results. It can be done.

Somewhere around E70 is the most that has been ran with modifications that increase airflow (intake, exhaust, etc.). A 50/50 mix of gas and E85 has been used the most. I ran the 50/50 mix for a month or two this summer and loved it.
