Cam timming??
I hvae notice a couple of companies are selling adjustable cam gears for the 944/924S. I know adjustable cam gears dont make HP but the do move around the POWER CURVE. So I have a couple of questions for you guys.
1. How far can you advance or retard the Cam gear on the 944 series 2.5L engine before valves start to bend?? 2. Has anyone done this to there P-car?? 3. Do you think it would be worth it?? my power curve doesnt really start until 3,500rpm, It would be sweet to get it around 2,800 or 3,000 rpm

About +\- 7.5 degrees.
Or about two teeth on the cam gear before you start bending valves. The DME controls ignition timing by changing where the distributor fires in its car. (thats why the dizzy rotor is so wide) AFJuvat

I can understand the benefits of being able to retime the cam due to the shaved head (thanks FR), but how would changing the cam timing (relative to the crank) improve the power curve? Especially with stock components?
