Russell, Just as a sanity check, before doing anything drastic, check
your pitot static system for restrictions. If that looks good, swap in an ASI
known to be good. You could just be having instrument failure. It's hard to
imagine even the B.U.C. killing off 40 kts. or more.

Good
thought, but I looked at the GPS a couple times today, and it was always in
the ballpark of the ASI. Also, the cross-check is my dismal climb
rate. My friend's 160 HP RV-3 climbs at 100 kts, and 2100
fpm. I have 200+ HP available, and can't even get to 100 kts in
climb. Best climb rate I've seen was 1500 fpm, and I didn't see more
than 1000 fpm today. I should be looking at about 160 kts without
wheel pants and gear leg fairings, and I'm seeing only 113 kts or so.
Very depressing...
The only
other variable is the prop. I'm using a 3 blade Warp Drive prop, and I'm
starting to question how well it may be working. It's certainly
absorbing the power, but is it effectively turning that power into
thrust? How can I know? Anyone else running a Warp Drive on a fast
plane?
I do agree
that it's time to step back and make some well reasoned observations,
rather than taking a chainsaw to anything yet. For sure, the cowl has to
go eventually, but I really didn't want to have to do that
now. I've thought about replacing the radiator, and modifying the
cowl into yet another temporary shape, but that's a lot of work for
another temporary cowl.
Thanks,
Rusty
