Interesting article

Here is an article about a new engine design, which is really a warmed up BBC.

Two things caught my eye.

One, they are trying to build an off the shelf engine package that will be reliable at 9,000 RPM and two, the fact that both Dart AND ProLine chose a gear drive.

Neither company has stupid people. Neither company cuts corners. And yet, these two companies decided the gear drive was the BEST way to drive the camshaft in a 9,000 RPM engine.

What’s equally eye catching is the cam in that block is raised .100 so a chain would be all that much longer. The longer the chain, the more issues you have. Same with the belt. That’s why a QUALITY, FIXED IDLER gear drive is a cheap investment. And worth every penny.


Evidently, Dart and ProLine didn’t get the memo that gear drives create parts breaking, valve train destroying harmonics and take too much power to drive.

Or they are just idiots.

Or maybe, just maybe they did the research and when you need accurate valve timing you use a quality gear drive.
