Rui stopped posting from work after I
suggested that we show IP addresses.

We'll have to wait until he gets home
from work to be showered with his
pearls of wisdom.

Huh, what is it in? I am pretty unfamiliar with them in person. I heard in SAIT they are horribly inefficient.

That's out of a Mazda ain't it?

Typically the RX-7 might have been in other models.

Early RX-7 I believe.  Far better engine
than the POS Ford V-6 it replaced.

For the love of sweet Baby Jesus, you
don't put an airplane engine in a car:

Why would you put a car engine in
an airplane?

As a generality, it seems guys want to install auto engines "Because they're dirt cheap compared to airplane engines".  When you dig into it, it is of course a pretty false economy.  For one thing you run the risk of dealing with outfits like Egginfelner.  http://www.avoidvikingaircraft.com/ Who knows how long Viking will last till Mr. Egginfelner looses interest and starts his next company?

Secondly as auto engines turn faster than is practical for a prop to make use of, so they need a well engineered reduction unit.  Many on the market are not that well engineered, but you won't know it till the fan stops turning in flight.  One of the fellows with a 13B in his Tailwind puked all the oil out the gearbox front seal on his first flight. It caught fire but he got it down and rolled the airplane into a ball.  He's OK fortunately.  From what I gather the gearbox builder redesigned the front seal arrangement after this event, I don't think it's really fair for businesses to use their customers as test pilots.

A product that I suspect is one of the better offerings is from Titan, for their T-51 Mustang.  Suzuki and Honda V-6 options for $9K to $10K, http://www.titanaircraft.com/engines.php but the small print says the gearbox and conversion kit aren't included.  That'll cost you another $16.5K!  Bottom line, if you want 'X' horsepower in your airplane, it'll cost you 'Y' dollars, regardless of whether you use a purpose-built aircraft engine, or an auto conversion.

Ok, I just wet my pants.

This is amazing:
