So what are you trying to say?

You should add this to the tread I have for Eaton TVS superchargers.

this is a totally different subject actually.
hence the new thread.

 

I wish I could read compressor maps. lol

 

where its darkest blue is where the supercharger is most effecient. i could be wrong, its been a while since i went over this stuff

 

That part I've got. It when terms like "pressure ratio" and "surge" come into play that I move on to simpler things.



Like intakes.

 

My question is the pressure ratio... Is that in bar?

So you take it times 14.7 to translate into PSI or am I totally on the wrong track... Because if I'm right that is a lot more boost than I expected.

 

Lamens terms.

 

9000-11000 RPM with 700-850 m^3/hr intake volume flow, and a pressure ratio of 1.5-1.7.

9000-11000 RPM is slow as ****

 

even at max eff% its flow rates are lacking.

and a grand total of ~4000rpm or so in that maxx eff% is week.

however if you drop a minimal amount to the 70% eff% range then its usable RPM range becomes much more forgiving.

73%-70% isnt bad for a roots blower at all.

thinking of swapping?

 

If I got that blower, I'd spin it to 17k no questions asked.

 

well dependent on your system PR the ill-effects of that excessive rpm might not be THAT bad.
