Tbsleeper,
That is at the crank of a 400L 2 stroke, i'm getting those number from the following mods and the what the quad shops have told me. Mods: 80 over prolight Wiseco Pistion, just under full race port and polish, .020 off the head with polished dome, 180 psi in the cylinder, number 9 plug, wiseco lower end, modified counter balancer area (increased oil volume),dual stage reeds, 38 mm tmx flatside with 390 main/35pilot, uni air with mod air box, single cable throttle, klotz 44:1 with premium or race fuel, lightened flywheel, AAEN pipe and silencer. on a 3/8 mile track in the straights with a 34 tooth rear sproket - radar clocked at 85mph, have not been clocked with the 30 tooth sprocket. There's a shop in Paducah that has a dyno for quads that i want to take it to this summer to see what the hp is at the rear wheel(using 19" American Racers).

 

proX if you look at my sig you can see what I done to my 400 scrammy and let me tell you, I am more then happy with the power gain that these mods gave it. I was in your shoes not to long ago and the great crew here lead me down the path a took as far as mods go. And I want to say it again, THANKS EVERYONE [img]i/expressions/face-icon-small-smile.gif[/img]
