Think of it this way... how many cubic inches are in a cubic foot. Then figure out how to convert minutes into revolutions.

2.55 pulley's on Gen V's....

15 PSI at 17 000 RPM?

Basically... lol. So far outside the efficiency range it's ridiculous. But we're talking adiabatic efficiency here with how much heat it'll create.

This whole thread is dedicated to Volumetric Efficiency.

Now a 2.55 pulley on a TVS1320...

Spoiler Alert!

Can anyone tell us what the volumetric efficiency is using this example???

84%?

Yes... lol

thermal matters more with a heaton.

It sure does. Did you think I was gonna leave that whole bit out? lol

Now what if I told you guys the TVS 1320 is as good or better than the Whipple in this article...

However I am curious as to why.

The 90 ci number doesn't mean anything without temperature and pressure information attached to it. A blower will move a lot more air without any pressure on the downstream end of it. But it won't be very effective as a supercharger.

You didn't say whether you wanted to know about the volume of compressed air or uncompressed air. Or what your inlet and outlet temperatures are.

Why don't you check the maximum MAF voltage reading and compare it to the MAF transfer function to figure out what mass of air has entered the system?

Then divide the measured mass by the density of air at the temperature and pressure of your location on that day. That will give you the volume of uncompressed air that the supercharger is moving.

I am a little skeptical that the TVS would beat the Whipple in ultimate performance, but in performance vs. price, I would believe that.
