13B Intake Manifolds
Paul,
 
I hope you took some comfort from the website that Rusty mentioned. According to it, running two 72 pound/hr injectors with naturally aspirated BSFC would be sufficient for 209 HP at 43.5 lbs fuel pressure with an 80% duty cycle--you're fine.

Hi, Barry....sorry for the delay in responding....I flew down to West Palm Beach to try to test fly a 13b powered canard and give a little flight instruction in a Cozy.  I think you made a few of my dormant memory cells come back to life.  I believe that Dave Atkins DID say the injectors are 850cc.   As far as horsepower expected, I will be pretty happy if I can get 170 horsepower. Anything above that is a Christmas present. I do not have a turbo installed.  My engine is now idling nicely around 1400 rpm.  It might idle better at lower rpm's once I lean it out a little and install the prop? Your mention of the duty cycle is interesting....that might be why my throttlebody drips some fuel after engine shut-down, even if I turn off the fuel pumps to kill the engine. Thanks for all of your input and information.  Paul Conner
