[QUOTE="greg brillus, post: 125354, member: 597"] Their explanation was that the Vincent muffs are quite strong......the clamping force of 30/32 Ft Lb's is not a huge amount, so the distortion is not that great. You generally only use the Torque plate for the final honing process, not the boring to size. The guy's that build very high performance turbo engines that put out huge horse power actually heat the block up to full operating temperature when they do this as well. I know some of these blokes that build these engines and the details they go to are quite amazing........a lot of these high spec engines run very high toque figures on their cylinder head bolts and this distorts the top of the cylinder block quite a bit I'm told. They run vacuum pumps on the crankcases and many other details all to gain extra power. Some of that technology we can apply to our engines, but it is costly and time consuming.........I wanted to make Titanium valves for my Vin racer but couldn't find anyone who was prepared to do it........the numbers needed are not high enough for them to bother........custom make some from blanks of titanium........very expensive.......you have to weigh up cost verses gain.
