Racing Beat did a real crappy job of installing the fuel injectors.
 Kind of strange as they ignored everything we did over the past 18
 years to address this issue. Actually they ignored everything we ever
 did :-)

 RB was using the Mickey Mouse Paul Yaw injectors with filters which
 have their draw backs as well.

 We nearly lost the TTC airplane not to mention Dan on Thursday to a
 possible massive fire when we were running it up. Safety wire was
 used to hold the injectors in alignment with the Paul Yaw filters and
 the mechanic left it off. Probably did not think it was necessary.

 The injector popped  out of alignment with the Paul Yaw filters and
 sprayed raw Menthol all over the engine. I ran over and pounded on
 the canopy to get Dan to shut it off. Partly my fault for not
 noticing the missing safety wire.

 The proper way to do it is put all the injectors in a line and use a
 fuel rail. The fuel rail is key to holding it all together.

 Hi Guys

 I do agree that the injector mounting is not rite. But!! I do not
 agree that the Paul yaw injectors are micky mouse. If the injectors
 where mounted in the correct fashion. There never would have been a
 problem.

It is totally unnecessary to have a cheap anodized extension on each
and every injectors that does ABSOLUTELY NOTHING except make it
prone to fail. It is a marketing ploy to make the injectors look different than the
ordinary  mass produced STOCK Bosch injectors witch they are. People
will think they are something special and pay twice as much money. I am not
fooled :-).  It is a scam pure and simple.

As you can see from these pictures there is absolutely nothing
in the purple extensions but air :-)

The drawback is yet another O ring joint and a Mikey Mouse steel clip
to hold them together. Just something else to cause problems.
That is exactly  what failed in our case nearly burning the aircraft to.
the ground and possibly  killing Dan.

I have known about Paul Yaw for at least 18 years. Here is Mazda 13B engine he built
years ago. The Canadian  sea plane purchaser was very disappointed in the HP
because it was not a p-port. It was a cut down side port stock manifold.  Basically
the same basic parts RB got 650 HP out of  with a p-port :-) Believe me, the
purchaser would have been quite happy if had as little as 300 HP.

I don't think it even had a gear box. It does not look like it.
