I remember something like that from the 1970's. Do a patent search.

Today it would be reasonable to design a hydraulic or electric (as in motor) actuated cam advance mechanism controlled by a microprocessor. Then you could program it for any number of variables including load, air temperature, engine temperature, manifold vacuum or turbo boost, altitude, throttle position, fuel octane, wife's name......

I'm game if your game.

It would be wicked if IPD made one, they have so much stuff, but this is the one thing they are missing.

They have them for jettas, foxes, golfs etc. and porsches (same cam sprocket on cars, just a different cam, so it fits on any VW of that type, 4 banger), so why don't we all get a petition or some BS liek that and tell them to make it.

I want maximum usage of torque, and I don't want to spend money on teh mnaul adjusting sprocket because I figure it might not be worth it, but and AUTO adjustable one definately would be worth it.

The only prbolem you run into is ignition timign gets all wacked up if you have the type of engine that gets its ignition distrib driven right off the cam. On VWs and Porsches this was the case, and not many people realized that they are actually losing horsepower because their ignition is retarding at high rpms and advancing at lows, along with teh cam.

On the volvos, or at least the old ones the cam does not drive the distrib so thats cool, but then i hear on one of the later 4 cyl engines it does get driven off the cam, anyhow, an aftermarket ignition then digital reading off the flywheel is my recomendation.
