DaveK 0 Posted May 25, 2006 Im going to make one of these at the weekend hopefully but need to know how much the manifold end needs tilted downwards so i know what angle to make the plate. Any1 know as it would save me the time of putting the engine in and make it alot easier to fit the plate. cheers Dave Share this post Link to post Share on other sites

DaveK 0 Posted May 25, 2006 not atall, just need to know how far up the manifold hits the bulkhead Share this post Link to post Share on other sites
fangio 1 Posted May 26, 2006 Dave, from what I've read in the past when people have cut and reangled the manifold itself, usually 3mm is taken from the bottom edge and truncated to zero at the top (which I'm planning to do). So you're not talking about a lot. Hopefully that should give you something to work from. Cheers. Paul. Trade secrets my @r$e. Share this post Link to post Share on other sites
petert 588 Posted May 26, 2006 ...... usually 3mm is taken from the bottom edge and truncated to zero at the top (which I'm planning to do). Trade secrets my @r$e. That's only 2.3 degrees. Nowhere near enough. If you're good enough to make one you deserve to know - 6 degrees. I originally made them at 5, but you can still have issues at the bulkhead. If you're really on the pace you'll mill 3 degrees from each side. Don't forget to make 6 deg. tapered washers to suit. Share this post Link to post Share on other sites
DaveK 0 Posted May 26, 2006 yea the plan is to mill the exhaust proflie on the cnc miller then make angled washers and slightly widen the holes on the manifold to keep the bolts all straight thanks for the help guys Share this post Link to post Share on other sites
