IFR Diffs: 2009 C6 vs 2009 Z06 & 2008 C6

[ThrasherC6]

Does anyone know why the IFR vs. Pressure Delta numbers are so different on the 2009 C6 vs. the 2008 C6 and 2009 Z06?

2008 C6 shows 41.74 from 128 - 400 delta kPa. Same with the 2009 Z06.

But the 2009 C6 shows the following from 128 - 400 kPa range, in 16 kPa increments:
11.80428 12.69270 13.52396 14.30581 15.04794 15.75422 16.43143 17.08055 17.70642 18.31097 18.89615 19.46389 20.01515 20.55189 21.07506 21.58563 22.08361 22.57191

To confuse matters more, the table editors all indicate that numbers are in #/hr, but the tooltip in the Engine dialog for 'Flow Rate vs. Press' indicates that numbers are in g/sec. Obviously the 2008 C6 and 2009 Z06 numbers are in #/hr, but what is up with the 2009 C6? What am I missing?

the 400 kpa ABS = 0 Kpa VAC

you can right click the table and change units from lb/hr to g/sec

and the 09 c6 isn't limited to 63.5 lb/hr

Thanks, I realized that there is a difference in the 2009 C6 that is addressed in the 2.23 beta. When I look at the flow rates in the beta, they show up as real lb/hr numbers instead of those numbers that look something between lb/hr and g/sec.

no prob, is it possible to have 2.22 and 2.23 installed on the same pc?

Yes.

- Install 2.22
- Copy the scanner and editor EXE's off to a 2.22 directory
- Upgrade to 2.23 and copy the EXE's off to a 2.23 directory
- Copy whatever EXE you want to run back into the install directory before launching.

This is not an officially supported HPT method but one that has worked for me.
