| what's been done to your "851" to get 134hp at the wheel!!???
good question !
here goes
955 competition piston kit
Pankl SP rods (with 21mm little end) not Ti...
lightened and balanced crank
heads converted to 37mm inlet and 31mm exhaust spec
heads ported and gas flowed
race cams (431 inlet and G exhaust)
lightweight alloy flywheel
factory termi spaghetti system
955 Corse chip for the P8 ECU, rev limit 12,300rpm
running twin green injectors per tb
power commander installed to middle 2 injectors - sorts out air/fuel mix beautifully
factory carbon air intakes & airbox - uses tank as top 1/2 of airbox, it's sealed or as near as can be made so and makes a huge improvement to how she runs
slipper clutch by STM
Ains the motor has now done 1200 miles and I've just had her apart to look at condition - openers and closers all Ok, cams Ok, valves Ok, Bottom end is also fine. I think that the bottom line is that the miles I've done havn't exactly been high stress and, aside from thrashing around the IOM, she's been shortshifted everywhere. Shortshifting at 9.5 / 10k with this motor isn't a penalty either as it pulls as well as the torque and power curves suggest. not sure how long the motor will last but I'm expecting to get around 6000 miles before a refresh is needed
Loony - yeah remember the discussion, pity we couldn't have met up - another time maybe !  |
