RUNAMUCK Posted February 3, 2009 Share Posted February 3, 2009 I take it this engine doesn't use a woodruff key setup then? You've got the option of offset keys then, with no weight penalty. Much simpler for engineering fuckwits like me... You can use offset dowels. Quote Link to comment Share on other sites More sharing options...
Honda Ass Dragger Posted February 5, 2009 Share Posted February 5, 2009 I have jsut realised that I miss Veega coming into these threads and telling everyone that he knows everything then arguing till he's got brused typing fingers Bring back King Know it all Please Quote Link to comment Share on other sites More sharing options...
Brock-Lee Posted February 5, 2009 Author Share Posted February 5, 2009 hmm, thing is that vvega actually did know a huge amount about engines etc. And imo the information that he has taken with him is a loss to the forum. anyways, that aint what this thread is about.

forced Posted February 5, 2009 Share Posted February 5, 2009 Forced induction needs something to force against - in this case a closed exhaust valve If the theory doesn't work , then it's wrong. With a turbo motor, the average pressure in the intake manifold is very close to the average pressure in the exhaust manifold, therefore it will act in a very similar way to a N/A motor cam wise (pressure differential).

Steve This is going to be another arguement but the exhaut gas temperature kills the pressures being the same due to the expansion of the burnt gases trying to escape alot faster than the cold gases on the intake are trying to get in. This is why the trim on a turbo is more important to get right than the compressor side when going for bigger revs. Corey Quote Link to comment Share on other sites More sharing options...
