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?....

    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.

What PSI are you running the fuel at for TTC ?

The standard yellow RX8 injectors take an 11mm drill bit.

They also sell the 14mm drill bit (Bosch)

150 PSI. I am not allowed to change the TTC fuel plumbing. Just fix it :-)

Here is a system I designed and built.
