M240 Dyno Testing
Just curious ... the M240 has been out for some time now and I don't see much out there on dyno specs for WHP & TQ. The M240 has a the new B58 engine, slightly larger turbo and updated pipe work to help cooling than the outgoing M235. The M140 w/ the same B58 engine posted 349 BHP and 384TQ on a dyno in the UK. Has anyone seen any credible dyno testing done on the M240?? To produce the stock 4.2 (0-60 time) and 12.7 (1/4 mile) it would seem to be producing more power than the factory stated 340 BHP / 370 TQ. Does anyone have any thoughts or know of any recent credible dyno testing?
