I have a 2007 997S. NA no forced induction. Anyways a lot of people are telling me that running E85 would be better for my car as well as performance. Is it worth it? I know the gains are high on forced induction but how is it on NA motors? I know i need to change the entire fuel kit for this to work. Just don't know if putting on a NA is worth it or not. Can someone help me out on this?

 

Everything I have read indicates major expense to retrofit and then no guarantees. Not for me!

 

I had a E85 sport truck once and didn t notice much in feeling any gains with the different fuel but did notice a greatly reduced MPG,s on E85....
Probably gonna hurt at re sale time too.
