I, like Mecanair, am putting all my injectors out near the bells.
Fuel consumption to me is way more important than throttle response.
Cars, like RX-7's, need good throttle response airplanes don't.
If necessary I will add injectors and use a 555 one shot
triggered by a push button switch :-).

Good morning Paul,
Please explain: (bells) ?+ (a 555 one shot)??
Thank you

A bell is short for the required bell mouth shape on the intake tubes.
It is where the air starts going into the intake tube runners.

A 555 one shot is a 50 cent integrated circuit you get at Radio Shack
that will pulse a driver transistor that will in turn fire the
aux fuel injectors once for an extra shot of fuel for a momentary acceleration.

Acts like an accelerator pump on a carburetor. This is worth it
if you fly 50 hours a year and you are burning 10 gallons an hour
that is $1000 dollars a year in fuel cost. If the BFSC is 5% better
than you will almost pay for it in the first year and your range
will be 5% further. 

I don't think I need it and I am going to try
the injectors near the bells with out the aux acceleration injectors.
