Cam/Adjustable pully
 
Hi to all,
I'm in the process of rebuilding my engine done the main/big-end bearings,new rings etc, i'v took a risk and ported my own head to gasket size and polished it up.:D
Does piper still make a Racing/fast road cam? and if so what do they cost?
What does the adjustable pully do in ref to power? and where do i get one from?.

Cheers
Andy

and on another note, i doubt piper actualy developed the cam on the RR, its only a regrind, so what state of tune was the engine in when it was decided that by advancing by 2 degrees would give max benefit, tbh the car needs to be run on the RR, then mess about with the cam timing to see what suits it best.

Its a wider duration cam by 14 deg's and as a result the full lift occurs 2 deg's out when used on the standard pulley. Its not been advanced as such.

By adjusting the timing normally a small improvement or loss will be noticed in either midrange or top end power.

If it was twin cam you have a lot more options coz you can adjust the valve overlap.

[IMG]http://i13.photobucket.com/albums/a2...1/01070007.jpg[/IMG]i can still get them made, usually in batches of six. They were £72 inc having your original pulley machined. I have a couple of peeps interested in them, so if you want one put your name down.
Cheers
