gomerkfx700 Posted September 29, 2012 Report Share Posted September 29, 2012 very great reading guys way farther past my understanding in the math department but i really like the concept of trying to get everything you can get out of pump gas. i would like to try this kinda thing with my 421 serval when i get it ported. would really be nice to get with in a few hp of a regular bolt together race fuel engine. and save 7 bucks a gallon on gas Quote Link to comment Share on other sites More sharing options...

So far in my testing I haven't seen much if any gain from higher compression and timing on them. Typical 2 strokes don't see a peak power gain from increased compression. They see a gain in the frontside curve and can acctually suffer a loss of rpm and peak power potential from too much compression. Quote Link to comment Share on other sites More sharing options...
