Well I spent tonight at the drags. I'm runnung Full HMF with a dolbec, prodesign intake, 15t front, stock tires and 91 octane. MY fastest 1/4 was a 15 flat at 78.88 I'm uploading a video and will post later racing against an ltr 450.
Strapping the front and rear suspension down helps a lot...it doesn't allow the suspension to unload when you take off..reducing roll and keeping the frontend down instead of wheelieing hard. I do this every time I go. Get some buddies to stand on the front and load the shocks and then run a ratchet strap from one a arm, through the frame, and to the other a arm...the ratchet the sucker down. Its worth it man.
