Does anyone know where I can find performance cams for the 8v 944? I have only found one source so far, and they only offer one solution. Web Cam Inc. Web Cams
Also does anyone know what the stock grind is on an N/A, an '84 to be specific, I don't know that it makes a difference. I ask because this Web cam seems to be pretty agressive. Has anyone used this cam? What type of performance and economy do you get with it?
I was also wondering about shaving the head in addition to a cam, what would you reccomend? And if I were to shave around .3-.4, what would you suggest I do for timing?

Crunky, where are you located? You should stop by my place sometime to see various 944/51 with various levels of mods. BTW, I have a 951 and a 84 944 with mods.

I am currently living in Queen Creek
, but In about another month or 2 I will be moving to Tuscon to go to school. I don't know if that will be better or worse than QC. I will be in a bigger city, but still not very populous, but I wil also be even further than an even bigger city, but hey atleast I'll be closer to Mexico
.
Oh and I like your Avatar BTW lol.

For a cam I'd go to Jon Milledge:

I've considered Jon Milledge cams, but damn they're expensive. Would you recommend anything else while doing the cam, like timing or head work? Or just drop it in and go?
I guess the price isn't that bad, I'm used to working on VWs lol.
Aslo, do you whether it is possible to get adjustable fuel pressure regulators for early cars? Everywhere I look I can only find ones for '86+ cars. Whats the difference?

Yeah, the Milledge cams are a bit pricey. I'm used to buying quality pairs for twin cams for the same price. But, these are Porsches and Milledge cams are ground from factory billets and maintain the stock base circle so there is no dinking around with additional shimming and stuff.
Regarding the adjustable FPR, I don't know the difference. Didn't even know there was one.
As for recommendations, if you buy a cam from Milledge, I have little doubt he could tell you exactly what will bring results.

What is the lift / duration of the stock 944 N/A cam?
How about the turbo?

I'm surprised to hear this considering the n/a cam is considered an upgrade for the turbo cars. Here's what I uncovered for the cam profiles:
![](http://forums.rennlist.com/upload/camdatafull.jpg)
As always, cam geometry is a compromise of different characteristics. The 944 cam is reasonably good IMO for the car it was designed for. Does this mean that you can't free some flow by altering it? Absolutely not. Of course you can, but all facts considered it would certainly affect the driveability. Ever driven a hot rod with a real high-lift cam and loping idle? I have. It would absolutely suck for street driving.
I also suspect that getting into custom-ground cams is one of those regions that the return on HP per dollar spent is among the lowest. There's a lot of HP to be gained in the heads of these cars and that can be done for a lot cheaper than custom cams.

Why the scary gloom and doom? I would have zero concerns about running the Milledge street cams in a street car. Not all non-stock cams are loping high-lift, high-overlap cams.

Look, even if the low end of Milledge's published figures are what hold up, $650 for 12 hp is a bargain. Show me any mod for an NA that gives that kind of return. Hell, show me any mod for an NA that will even net half that hp.
