You could get a lot of horsepower from those engines if you had the skill, time and money for it. My friend stopped racing his when it got to the point that the helical-cut primary drive could no long withstand the forces being fed through it. There is a shop in England that makes a straight-cut primary drive kit for that engine. Cut from billet. When he found out the price he decided it was time to stop development on that project :) -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
