MY FREE ENGINE WELL ACTUALLY AN ENGINE BUILT WITH SPARE PARTS PUT OUT 190 RWHP
ONLY 10 HORSE LESS THAN MY BIG BORE ENGINE
Only 10 horse less than my big bore engine
I have to say im pleased to have squeezed 190 RWHP out of my spare parts bins, yes a complete miss mash of ZX10R engine parts spanning 10 years & 3 Generations of ZX10R engines. A set of 2006 (GEN2) engine cases with a 2010 (gen3) cylinder head, a 2008 (gen3) crank shaft, 2015 (gen4) pistons & rods, a 2012 (gen4) exhaust cam, a 2009 (gen3) inlet race cam. 2008 (gen3) clutch basket, oil pump & generator, starter motor. Yes that is a miss mash alright.
Tuning wise there was obviously some work involved, the crank was lightened by 1.3K balanced & edged, balanced rods & pistons, i epoxy ported the head & shaved 0.6mm of it. the cams i dialled in at 112-112. I flashed open the secondary butterflies at the top, the dyno work i gave to BSD, yes there good but all the power figures you read in the MCN are theirs so you get a idea of consistency. The torque is no where near my big bore figures but its up 8 against this stock bike when in 2008 MCN put it on this dyno it was 164 RWHP with 73 flb torque
So a spare parts bin gave it + 26 RWHP & + 8 flb torque..................
