sorry to drag up an old thread but with all you knockers would just leav it alone if you havnt got anything constructive to add to someone wanting to have a worthy technical discussion about performance then shut the f** up
you might find the boy a bit abrasive but rockers are the biggest problem with these engines, i have powerful atmo m20 race engine its not a big stroker its a 2.7 and makes over 245Hp at the wheels and I could fill pages and pages about all the problems i have had with the rockers, i have tried several aftermarket and or billet rockers, oils additives cams and spring combinations and it all comes down to the same thing, to go over about 7600 rpm the loads over the tip of the cam lobe get too high to maintain oil film its just too thin after centrifugal force has cleaned most of it off the cam and the rocker pad starts to chop out verry prematurely taking the cam with it, the only true solution is a roller follower, this is something i have also been developing for some time, i have all the geometry information and have a cam grinder willing to develop the cam profile but I still need someone to make the rockers.sigpic245Hp at the wheels

Obviously you haven't seen this kid's E34 turbo build thread. He doesn't even have an E30.

What a thread you picked to champion your development of roller rockers for the m20. If you are serious, you may want to start a new thread that doesn't have the stigma associated with this one. Welcome to r3v!sigpic

Yes, that would be a good idea. Cause people remember the ass hat of an OP the guy was that made this thread. And i'm sure no one is wanting to be connected with this. So if you're serious about these, post up a new thread so this guys legacy wont be shadowing your project.
