and I'm still saying you that you have to define the stresses you are saying the cam couldn't take.
I'm not going to build one and I'm not that interested, but I'm convinced that if the boost pressures required were low then this would work.
3-4 psi on one of these engines will do a lot for performance.
I'd be willing to bet that a cam driven blower cold support 3 psi and not snap anything. I'm also aware that tube shafts (like rear wheel drive driveshafts) are able to withstand just as much stress as a solid shaft of smaller size.
If he's thinking of getting 10psi out of it then I agree its hopeless. But something to make the intake more efficient then maybe...

Who cares if it can be done. The question is why? The Vortech unit is now reliable (again, dont know anyone with a new model that has failed) or can be made reliable by some one on the board  Or go Turbo and have traction problems...

I was actually thinking about the powerdyne SC. The "silent drive" with no oil requirements seemed attractive from a reliability and installation perspective. I have to search through CEG to determine if they are good blowers.
BTW-The upgrade kit for vortec is $2016, and you have to send in your blower for redesign of the drive shaft. I think there is a better price if you are the original owner. Any original owners out there who already sold their units??? If I get a massive discount for the upgrade, I'll split some savings with you

Anytime you are pushing 250+ FWHP you are going to have traction issues. A Quaife or Torsen will help a great deal with them, but they still exist. The real killer is Wheel Hop. Get better bushings (Urethane) and an LSD and it goes bye bye. You have to come gently out of the hole and mash it in a linear fashion as you get moving... Ahhh... I remember downshifting into 3rd at 40 and smoking the tires.... Oh the fun!

ask terry, he's the one that said no years ago when someone first came up with this hair brained idea!
I think you'd have to agree though that using the cam to turn a dinky water pump is alot different than using it to spool up a supercharger. And what good is 3-4psi anyway? Get yourself a 50 shot and call it a day...and more productive at that. Cheaper too.

And your point is?? Am I supposed to dignify this with a response??
Back on topic:
I didn't say I'D do it!! I just said the 3-4psi would go a long way.
Personally...I know better than to take OTHER peoples words on things anyway.
Why don't you search for the old pontiac sunbird (??) and see what a cam driven supercharger did for that car. Then tell me that a camshaft can't drive anything. Not only that, it used a cheap old style cam and not ones like ours that are lighter and stronger.
BTW, 4 psi was enough to push Wavrdr's SVT into the mid thirteens in the 1/4 mile!! 
I already stated athat I was running a 3.8psi spring in my wastegate and 3 passengers on the way to atlanta and I whipped my buddy's Audi S4 with chip and exhaust. So ummm yeah. 4psi does a LOT for our engines.
Other than THAT, yeah I agree a 50 shot of nitrous is easier and really cool. However, the bottle does run out.
In a long run, I'd take a 4psi blower that is always on over a 50 shot kit....assuming the kit worked.
