Will high compression engines running on alcohol accept a subercharger without blowing a head gasket. What I mean for High compression is 12.5 to 1 or higher. Also engine is 0 decked. Any thoughts will be helpful. |

Norm, you will probably blow the head gasket at that static compression, unless you've got an o-ringed head or block. Turbos and superchargers effectively increase the compression ratio by "fooling" the engine/carb relationship into thinking it's in a higher-than-normal atmosphere. I'm not an expert by any means, but I've always heard that one shouldn't go over a 9:1 static C/R when building for a huffed motor. Alcohol will allow you some additional static compression, but I think you're gonna be a bit over the limit. Roger |
