How many RPM
Garrett doesn't provide any info off their website and don't have any e-mail address posted either.
I'm not taking offense and hope you're not either. I think we are actually trying trying to debate 2 totally valid point. Another way to look at it would be this.
Take a supercharger for example. A company who makes a kit will not require a wastegate right. There is no exhaust fumes, so no need for a wastegate right? So they must determine how many rpm the thing is running at in order to see how many scfm is shelled out. Does that makes sens, or am I completly off?
I think I'll run a search to see how supercharger works. That should give me some pointers

Ok, I just read a few things about supercahrgers but wasn't able to find the answer to my question. It allowed me though... to find the right question to ask.
How do they control boost on a supercharger. I know a certain size pully turning at a certain speed should produce this amount of boost. But looking at RIPP's kit, they provide a boost controller with that. Now, on a turbocharger, the boost level is controlled by the wastegate which is controlled by a boost controller.
If there is no wastegate on a supercharger(or is there), what is the boostcontroller controlling then?

I have the ripp kit in front off me right now (literally). There is no boost controller, But there is a boost cooler (water injection). Your thinking is right with your formula's. The boost is rpm X (y). On the turbo the exhaust side of the turbine will be spinning at a certain speed to create a certain boost. The wastegate will keep the compressor at that speed. The only problem with this formula is that at every engine RPM the compressor must push more to keep it at the same boost level.(the higher the rpm the more air the motor sucks in on its own).

Totaly right
Ripp says:
•RIPP Boost Cooler, with digital controller
I read that part way too fast
