Rusty sorry for the confusion, you alluded to making a manifold
similar to the one Tracy is using, I was wondering if you are referring to
the old manifold or the new renesis manifold?
It's not
your fault Ian. I'm easily confused :-) If I copy one of
Tracy's intakes, it will be the Renesis shoe box type, though maybe a bit more
round than that.
FWIW, I
made a low pass at about 200 msl, and 180 mph at WOT (only briefly). The
MAP was 28.0. Ugghh. When I did the WOT tests on the ground, I was
getting 27.6" when the ambient was 30.10. Today, the ambient was 30.07, so
I'm getting some ram air pressure, but not enough to make up for the restrictive
intake.
Also, I measured another
Mazdatrix intake, and found that they clearly did their homework. The
inlets from the carb were just a tiny bit larger than the sum of the ports that
bolt to the engine.
As I see it, I can recreate
this same intake design, but with larger tubes, and a larger TWM TB.
I really don't want to spend that much on another TB though. I could
put something together like Tracy's shoebox, or I could do the 4 into 2 into 1
trick with a single barrel TB. I could also leave the current intake
alone and add that supercharger I've been threatening
:-)
Cheers,
Rusty (no, leaving it like
it is, is not an option)
