In response to In response to 0




          

12.5:1 is a very high compression ratio. Building an engine with a compression ratio this high would be somewhat tricky, on a normally asperated setup. I wouldn't try it unless you or whoever is tuning the car has a good understanding of ignition maps. I'm willing to bet that the stock timing curve wouldn't work with a compression ratio that high. Something like a full standalone or a MS&EDIS would be a must for a setup like that.

Are you thinking about using 12.5:1 pistons with boost?
