MitsuStyle - View Single Post - Does higher compression ratio raise TQ off boost?

**Goat Blower** · 11-16-2012

It's not apples to apples, but I was VERY happy with the 10.5 to 1's I put in my Evo, that thing spooled at idle, or at least felt like it. When I rebuild my current DSM motor someday, I'll definitely be going higher compression. For a street car, I think it makes a noticeable difference, if it's a drag car, lower compression and higher boost might be better.
