Do not use these fuel injectors. We had one blow apart today on the
TTC project.  There is a short section of .032 thick  aluminum
between you and a flaming death.

We are also still fighting the yellow snot built up in the aluminum
fuel lines as the result of burning Methanol. The boss will not re
plumb the fuel system in SS or rubber. He is paying the price of
ignoring that.

It is now plugging the injectors and we are on our third set. The
company that sold us our second set charged $800 for four.

You can buy the basic Bosch injector for $50  with out the adapter
on ebay. You may have to re-machine the fuel rail if you use the
basic Bosch injector as the upper O ring may be larger. The basic
Bosch 2000  injectors with out the adapters are just plain great.

As long as they are not plugged :-)

We are talking about just 4 injectors controlling 650 HP on  a turbo
two rotor! Each injector will flow up to 320 pounds of fuel per
hour.

I built an injector tester using six D cell batteries, a push button
and a special injector holder to take the 150 psi injector pressure.

The yellow snot is a seal or gasket or fuel cell foam dissolving in
the fuel. Why not racing fuel or avgas?.... . Lynn E. Hanover

Not in our case. Get a jar of Methanol and put a strip of non
anodized  aluminum in it. Within hours you will see the yellow snot.

Menthanol cools the intake system air. At our 650 HP level even that
is not enough so we use water injection to keep the intake air below
the 150 F pre-ignition limit. Other wise it would be over 200 F.

Paul, you should probably make a Motec map for gasoline and flush the system
of methanol after your testing. That way they engine would be pickled with  gasoline while in storage.
When you are ready for a methanol run you would switch back to the methanol map.
Barry Bordes


Good  idea.

We flush the system before running it but with Methanol.

We were not allowed to flush the injectors up till now.

One does not argue with the boss even if he is clearly wrong :-)

He is also the pilot so his life is on the line.

I'll suggest it today.
