hie B8 people,

i know it's a stupid question, but i just wanna get more information in this area.

what are high-cams for? and what advantages does it contribute to the engine?

what are adjustable cam pulleys?

As far as i am concerned, high cams refer to high degree of cam lobe, which enables your car valve lift to be lifted for a higher duration of time, and hence more fuel and more air into the combustion chamber at one cycle time compared to stock cams. They come in various degree, such as 252,272,and some at300 degree region.

As for the cam pulley it adjusts your engine(somethign to do with ignition timing i guess) so that it have diffrent broadband of power, eg more for pick up, mid range or high end. But you can only choose one.
Correct me if i am wrong, just my 2 cents

With proper installation and adjustment, for sure the adjustable cam pulleys will give you gain. With sufficient turbo and engine mod with tuning, it could give you very light and good engine response. Tried before on a fully modified Evo+VR4 engine combi with big turbos with only adj cam pulley with stock cams. The response is simply crazy.That was at only at 1 bar of boost.

And the redline cam pulleys is great stuff. Lightweight machined aluminium cam pulley as i am also using one..:)

wow, cools... i'm thinking of getting adjustable cam pulleys for my Mazda BPT from GT_Auto, but still doing a little study on it before i make that decision.

His pricing is also very good, but i have zero experience in tuning cam pulleys... i'm hoping that Millennium can help me out in the installation and tuning also...
