This is my last post on Dylan's original thread, he thought that he installed a NOS VW/Porsche cam in his new rebuild....

Dylan's getting .330 lift at the cam. I measured a new Web 73 and I get .320 lift
On the stock (used) cams I have I get about .275 at the cam, even less for a hydro.

It does have a rivet on gear and I’ve never heard of an aftermarket cam with a rivet on.

I’m at a total loss on this puppy. I’d hate to have Dylan rip out an OK cam, but things smell real fishy.


This cam has me going WTF! (IMG:style_emoticons/default/unsure.gif)

Is it a hipo regrind on a stock cam?
His new engine with stock FI will not idle below 1500rpm

I'm just running HD single springs, my engine is totally low-budget, I'm spending the big coin on my 2.6 nickies engine.

SDS does not tune itself!
It will come programmed roughly in the right direction, but you will have to fine-tune it yourself. One man can tune as they drive, as it has a very simple controller. You will need a lot of open road to do it this way. I had mine programmed pretty good in 2-3 hours.
A rolling road dyno would most likely be faster to program. Once programmed you can lock it down and remove the controller. If you were to get it done on a RR dyno (couple of shops in Calgary), you don't really need an A/F meter as the dyno shop will have a WB unit, but they're nice to have.

Mega squirt will have more build/install time and dyno time is a must.

Jake's first lifters have failed and they have gone back to the drawing board, no ETA on them at all. His lifter were going to be $350 vs. $450 for the ceramics.

No idea on the cam, it's hipo, but it's also an unknown. My scat cam has the same lift, but more duration and it seems to run OK. The SDS will run it, but how good is the big question. I would take out the pump and see if there is a number on the end of the cam.
