Just recently decided to built my engine,power goal is 800 hp with possibility of maybe going for more down the road. I'm looking at all the current forged piston offerings and all the different compression ratios from 9:5.1/10:0.1/10:2.1/10:5.1. The car is currently on E85 w/stage 3 fuel pumps and Doc race IM w/750cc inj. Had a talk to a reputable engine builder and he recommend go with the higher compression piston cause of the fueling and my power goals. Wondering what are you thoughts on what compression ration go with and is there anything else I should be taking in consideration. Really appreciated your help.
