2001Stroker Posted April 6, 2009 Report Share Posted April 6, 2009 Yes, 4mil crank. The rod pins are moved 2mm further to the edge of the crank webbing. That makes the pistons go up 2mm's more, and down 2mm's more, making the stroke 4mm's more than stock. Stock stroke is 54mm, and a 4mil is 58mm.

jbooker82 Posted April 6, 2009 Report Share Posted April 6, 2009 A 4 mill cranck will drop right in the cases. A 10 mill will requrie the cases to be trenched so the conecting rod doesnt rub. Quote Link to comment Share on other sites More sharing options...
blaster2006 Posted April 6, 2009 Report Share Posted April 6, 2009 IM going to do this to my banshee. Im really instgerested how muhc more hp it igves me. I want to see a dyno test. anyone have one. a longer stroke gives more torque, and slightly less RPM. good mod overall, im not sure if it also gives HP boost in top end drags , someone else would know about that Quote Link to comment Share on other sites More sharing options...
