The builder says he's rather not run a brand new engine at 4k if he doesn't have to. I would tend to agree so that's why I'm looking for a good second hand set plus HKS gtir cams are pretty hard to find new as far as I've found so far.There is no problem running in wild cams in a new engine. In fact its really common thing to do...
My last new GTIR engine had to be run hard to bed in the cams for how ever long and was perfectly OK, But I can see the value of not having to. Then you can just concentrate on bedding in the rings properly which is the most important part of running in a new engine.Fair enough, I don't have any experiences from doing the same that it would bother me
I'm not disputing that Ed, The engine builder asked me to find a good second hand set mate wasn't my idea lol.Just run it!! Try and find a cam that has been damaged from bad run-in? I've still never seen one...
Isn't the best way to bed the rings in to give it a bit of stick anyway? I always was lead to believe that over gentle running in lead to bore glazing etc.
