Did hear that certain 150 ProMaxs were tested at no-more than max. recommended rpm ( quite reasonable - but maybe not max power) and with a very oil rich mixture, maybe a bit of adjustment to timing etc ...
Been some good dyno stories over the years.
MP blew a few motors on their dyno at Hamble - mind did'nt happen quite so often if they did not park the fork lift truck on the hose supply to the dyno!!
