In fact, I don't believe I am aware of the limits on E85 at 12.5:1; I know people have pushed the car to over 600whp on built internals. If 13.5:1 has a limit on E85 then again I am sure it exceeds the strength of the stock internals and is outside of most people's needs, but the 13.5:1 will benefit many people who just want E85 and headers, which far exceeds those with FI, which far exceeds people with FI going for big power.

I am only referring to default power level of most FI kits around 300HP on the stock FA20 engine. I agree E85 can yield more power with 13.5 compression. But it will probably be still less than 300HP. I am not interested in E85 due to its much lower mpg and availability. I am not interested in a power level less than 300 HP. I guess I am moving on from this platform for the next sports car.
