How high will these things spin safely?

How much boost can be run with water/meth injection?

Where can you get additional pullies?

Thanks

I know, I know, Radix, Radix, Radix. Well, I can't just fork out $5,000, so I don't mind settling.

 

Richard I just remembered, when Allan tuned my truck I asked him about a cam. He said he had one that would probably produce 25-30 rwhp. I beleive it was a custom grind. Not sure though. By the way FMS is currently running a special on their cams.

 

That's awesome, I'll have to call him and find out the specs. Thanks David!
I probably won't be doing a cam swap on my 5.3, but I will have a custom FMS blower cam on my LS1!
