Cary,
Love the 'trombone like' intake ( simple and effective) and was wondering if
that was one of PL's slide throttle or something you did yourself.
I would like to copy that if I may, to identify the tuned length of my 1.75"
P-port. Is that threaded rod that you have used on the slide guide?
It would be very interesting indeed if you managed to get an in-flight
adjustable tuned intake and measure it's effectiveness.
Personally I would be happy to just test for the best length at cruise.
Keep up the good work!

Hi All;
Posted this on the other list - some of you may be interested in this
teststand setup as well...

I was hoping to have this setup running months ago on the test stand
with the Megasquirt - damn work is interfering with more interesting
activities...
The slide throttle is flush with keg.  The notch was to avoid the stock
water pump, I wish I had been annoyed enough to chop it up earlier...
Same for the adjustable, telescopic intake.  I will rebuild almost flush
with the engine and at a different angle flush with the bottom of the
oil pan after testing.
Usable range (from rotor housing face) is 19-27".  Could be modified for
inflight adjustment.
Injector location will probably make it difficult to pull fuel uphill
for start - we will see.
Based on Francois' (Mistral) comments I will probably move the injectors
closer to the keg.
Besides, they are mucking up the airflow.
One of the objectives was to take advantage of the smaller rotary
profile - the height/width could be shrunk further...

Cheers
Cary
