and let us know what post he was referring this formula to, then we can do some work with it.

sounds good to me, let's nuke this out

I think Ryan was just trying to say that if the SC gets hotter it will build pressure faster according to the thermodynamic formula. As temps go up so does pressure. However, increased pressure is not technically why you get more HP - it's the added mass of air. Although, they ARE a function of each other.
Not to argue with proven thermodynamic laws but that doesn't make sense to me. I thought that if you could cool down the charged air (I know you get more HP for cooler air, but) - you would also run a little higher boost. For instance, upgrade your FMIC and boost levels usually raise or how you get more boost in the winter. Is this not right. How can they both be true.
unless he means you raise the pressure faster being hot - agreed
but you make more hp being cold - I think
but aren't they a function of each other....I'm getting a headache with all these assumptions
Someone please clarify
Ryan did give props to the Radix - although he clarified his stance on the "leaking" past the blades. Aren't we in agreement that there is a certain level of inefficiency's with each system - and that all are well made for the technology of today. Although reliability of the turbo's has come up. Moregrip raised an interesting point....how long do the Garrett turbos last - understand that they will be running 500 degrees cooler than other applications so we could assume, (there I go again) (yes, I know the acronym) a longer life span.

a longer life span.Again, my position is, there is no way the twin screw SC can build off idle boost faster than a Radix due to the fact that it must first overcome its greatest negative to then build boost, however, once it starts to build boost it is more efficient at it. The radix, however, is a cheetah waiting to explode into a full sprint, so to speak, it is 1 step away from productive boost, while the twin screw is 2 steps. Now, can the twin screw really boost faster off idle? I say no.

here's a pick of some twin screw rotors, nice!
