Hi Paul,
I have turbocharged automobiles
(two of them) in my short life span, so I know a little bit about turbo, but not
an expert by any means, however, I would not under any circumstance even have
that device active in my airplane much less let it control fuel to a engine
under boost. If it killed your ignition instead of your fuel it still be a
bad idea (IMHO), but at least then you wouldn't risk damaging your engine from
lean fuel induced detonation.
I for one don't want any computer or other device
deciding when to pull back on the power, you could find yourself in a situtation
(say a mountain in your face - well, not likely in Florida, but you know
{:>)) where you could care less about 1 psi overboost verus getting over that
ridge line.
I am surprised that anyone designing a EFI for a
turbo would use that method, but I guess they do on automobiles, but I wouldn't
on an aircraft.
FWIW

Subject: [FlyRotary] turbo wastegate
requirements
Hi, fellow canardians. I am still sitting
on that fence between turbo or not to turbo. (I have some splinters in my butt
cheeks from that fence). I was reading the installation and
operation manual that came with my MicroTech electronic engine management
system, and under "setting up" there is a section entitled BstCUT, which
says "This feature prevents turbo engines from overboosting by cutting all
fuel supply when bost pressure exceeds the limit set in theBSTcut screen,
i.e: if you set this value to 10 psi, all fuel supply will be
immediately shut off when boost is 11 psi or higher." Does this sound
like a useful tool in installing and setting up a turbo on my 13b?
Please don't flame me, as I know less about turbos than I know about
understanding women. Does this mean I would not need a wastegate?
Thanks in advance for your replies. Paul Conner, Mobile,
