My bro and I just got back from KBR of Utah from getting the 700 Dyno tuned. For comparison purposes his first 700 with a full HMF pipe, K&N Intake, and Dobeck controller put down 44.98 HP & 43.63 TQ. Peak HP was at 5800 RPM. His new 700 with 250R intake, CT pipe, Dyna box, 12.5:1 JE piston, Web Cam, and ported head by BW..
53.46 HP & 47.67 TQ. We first removed the baffles from the CT pipe to see the A/F and it made just over 52 HP. With the baffles installed ( 6 more discs added ) it made the 53.46 HP AT 6500 rpm.

AT 6500-7200 the BW Raptor makes 10 hp more. I'll post a chart if Buddah will take a pic of it.. It makes 47lbs tq at 4700rpms.. This is on pump gas..

I dare say it... It revs like a YFZ!!!! but doesn't do any good to go above 7300 as power falls way off.. I hope he'll take a pic of the dyno chart..

What are piped filter'd 700 Rappys doing on your dyno???
