I got some DW 800s from a customer on trade. Had them checked out @ RC Engineering. I figured they had worked for a year and a half with no problems so they probably wouldnt die on me :-P
So I switched it up to E-85 and they maxed out @ 411 Dynapack whp - 350 torque (375 hp on GReddy's Mustang) and thought... that is just about enough on stock pistons, rods and clutches. Not tempted to go for more since I cant!
