"The turbo could be sized for a car application,"
Exactly the turbo is from a car application. The amount of boost is
actually ok for the present time. I have seen 35 on the MP gauge and feel
that I can tweak the tuning of the engine a bit more. If I'm now working
your number correctly, all I want is about a total "hg increase of from
25"hg to a max of "40hg which is roughly 7 PSI. Mixture has and is an open
issue with the Revflow. With each engine run I'm adjusting the settings, or
shaving the needle a little to enriched the mixture at WOT. I think one
more shave will get me to rich at WOT. Once I determine the needle
dimensions at WOT, I will start to carve a smaller needle so that I can have
better mixture control at mid range without having to make such large
adjustment to the mixture lever(fuel shutoff) every time I change the
throttle setting. I'm also working on the CHT cooling, by reworking the
baffles. Even with a lot of gaping holes in the baffles, I was able to make
a 7 minute max power run and not go into the red. I still have 4 of 5
baffle tasks to be completed. I still need some more welding to the intake
system, but for now rubber connectors and clamps secure the system. I plan
to connect the control for the waste gate today or tomorrow. If my waste
gate control works as planned, I don't see any stoppers to prevent me from
getting airborne by next weekend. That's not to say that don't still have a
lot to do. My current list has about 30 items open, and as I close one or
two, I find from one to three to replace the one's that complete.
