Rob
Thank you for your quick reply. I will use your numbers for my test
calculations. I have an order pending with Revmaster for new heads and
carburetor to get rid of my Posa (per Mark's comments). In that order, I also
asked for an engine manual so I will have the right data but your assessment is
correct...my calculations should accommodate a WOT scenario and not economy
cruise. Always an eye opener to ask.
Best regards

Luis,
The 8 gph came from the Revmaster engine manual, just found it. Page B-10.

Luis,
I just checked my records, and I used 8 gph as the minimum requirement for my
Revmaster 2100D. I can' t quite recall where 8 came from specifically. But 3.5
gph is the economy fuel flow - not what you need on a full power climb out
after a botched landing.
When testing this, I got 12 gph in the level config, and 8.5 gph in the nose
high config. I used 3/8" fuel lines, gravity fed.
Thanks,

I watched the EAA video on fuel flow test and was trying to find the BSFC or
maximum fuel flow rate for the VW engine with a Posa carburetor. If I use the
default of .55 in the formula, I get a fuel flow rate of 6.8 GPH which I know
is excessive. From reading some of your pilot reports, I am suspecting a fuel
flow rate of about 3.5 GPH. I would appreciate some feedback on those familiar
with the Revmaster 2100D.
Thanks
