I would rather believe the people with engineering degrees when it comes to engine and gearbox issues compared to a so-called physicist ("with gravity and all that stuff.") who has displayed no evidence of the knowledge someone of such education should posses. But then I would still stick with the engineers on such matters.

Whoever you are, one thing is clear – you like to antagonise and cause commotion for no reason. You went to the trouble of registering with the site for this sole reason which baffles me. You could have done the normal thing and a) said hello first and b) again, in light of being a new member, you could have contained your wonderful anger at the gear speed-graph and provided some constructive criticism instead of your twatish comment

P.S I'm also studying Mechanical Engineering at Uni (1st Year), could be firing a few questions at the already graduated engineers now I know who you are
