Greetings,
I'm still a bit concerned
about the static MAP readings that I'm getting. This isn't something
that just happened, but rather has been going on for at least the life of this
particular intake setup. At on point, I was almost convinced that the TWM
TB ports were just not providing an accurate reading, but now I'm almost
convinced that they are. Has anyone measured MAP at WOT static?
I got the following results
in a few tests the other day:
1- 27.6"
This was with my normal configuration, which is an inlet inside the radiator
duct, feeding a 3" SCEET hose, to a fiberglass duct that covers the two barrels
of a TWM TB.
2- 26.3"-27.0" (erratic
probably due to prop blast across the inlet) This was with the SCEET
hose removed from the TB fiberglass duct.
3- 27.4"
This is with a fairly small K&N cone filter on the inlet to the TB duct
where the SCEET hose normally goes.
From this, I see that the
K&N filter seem to have no significant effect on the MAP, which is good,
though I still don't know if I can fit it in there.
I've got some numbers from
Ed, and also have an idea what Tracy runs, but those have always been in-flight,
WOT, low level runs. I'm going to try that at about 1000 ft at some point,
but would also like to know what folks run static. Anyone got any
readings?
Thanks,
Rusty (not willing to give
away free power)
