Default Turbo Cam?

For an TT L98, what cam manufacturer do you recommend?

I'm sure you would like a custom grind here. You could have anybody do it really, cam's aren't those kind of parts that break.

You'll probably want something with more intake and less exhaust duration than normal. The larger intake time will help the air comming in and the smaller exhaust will give the exhaust air more velocity to spool the turbo better. Just my $0.02

I called Harold at Ultradyne cams, and he was very happy to discuss the reasons a turbo cam is different from a supercharger cam, from a NA cam.

The hyd roller was about $300, about 2 years ago.

My engine builder recommened Ultradyne because he likes the way the lobe is ground to close fast , but eases up just before the valve hits the seat, putting less stress on the valve head.
