Max boost on a supercharger

Madcow

Rusty is correct. Different forced inductions units at the same PSI can have widely different air flows. If you're curious, pull up flow charts for different turbos and compare their CFM at the same PSI.

I used to work with axial and centrifugal compressors. And worked with flow dynamics for a little bit. Believe me. It gets weird at times. Try and figure out flow accelerated corrosion in steam piping.

You're oversighting what I am saying also; I'm not talking about cfm,flowcharts,efficiency,of various turbos!
I'm simply stating that on a 370Z/ with equal intake manifolds,throttle bodies,piping,etc...a given boost pressure (measured at intake) is the same/ regardless of 50,150,350mm turbos (1,2,4 or 6 turbos) same difference.....yes, I agree that a larger displacement turbo/turbos have to work less harder to achieve same boost; but anything above 10psi is wasting(dumping out exhaust) the smallest,harder working device will get hotter/ producing hotter air (less power output) but reading boost pressure going into the cylinders will be equal = 👌

Maybe it's the efficiency then but a good twin turbo setup alwys nets bigger numbers at the same psi as a single.

I think you guys are putting the PSI on a pedastool. (40 year old virgin reference anyone?)

PSI is just a by-product from Forced Induction (and an undesirable one at that).

The original question was what were the upper levels of boost being ran on superchargers.....not how boost is compared from one to another.....any info that pertains to that question ???

roplusbee

Some people just need to read before they post...................or spew information (or mis-information, whichever applies) all over the forums. How about watch an "engineering explained" or "how things work video" first?

I see not much has changed since I was last on the forums

Yeah. What a crime it is we started talking about other supercharger applicable content. Might as well lock this thread up.


OP. There is a sticky that has all boost applications, power made, kit used, and psi.
