Title: F4U-4 Fuel bug
Post by: Octavius on November 22, 2004, 04:39:31 PM

I grabbed a -4 the other day with 75% fuel and a DT.

I jettisoned the DT on climbout to see roughly how many minutes of fuel it contained at Mil power.

When I dropped it, the E6B gave me a reading of 16 minutes on 75% gas in the Hog4 (2.0 fuel burn).  Is that correct?

So then I engage WEP momentarily and the flight time increased by a few minutes!  :eek:

Posted before Oct, and its correct the wep is water injection whilst in use it requires less fuel.

haha, oct is a newb.  Even my mother (R.I.P.) knew WEP in the F4U-4 uses less fuel.

Edit: Now that oct feels stupid, I do too. How does this work? Does the engine actually overheat after 5 min of WEP usage, or is this just a representation of running out of the water being injected?

Isn't it a water/alcohol mixture?  And if so.. I believe it would overheat due to the extreme heat of alcohol during combustion.

 Alcohol burns at a much lower temp than gasoline. Allso the water in the mix lowers the cly head temp. I am pretty sure the Alcohol content was just to keep the water from freezing anyways and not as a fuel booster.

there is a bug in F4U fuel usage. ive noticed  on E6b the GPH
will fluctuate up n down on its own in level flight.
example:  GPH will read 500 then suddenly blip up to 660
then jump back down to 500 all in a matter of a sec.
