wastegate requirements
<... The wastegate lever has very little

So why not adjust (shorten) where on the lever you attach your cable
That's how I got half travel on the lever
:-)
What would enlarging the wastegate
involve? Probably a MAJOR mod for little benefit.
Each turbo version is a little different. If
you're going to use a stock Mazda turbo, go with the Series V- 89-91,
since it has a much larger wastegate to start with. Even this can be
ported, though I haven't looked to see how much room there is to
grow.
Also, keep in mind that you have to use a correction factor
when reading Todd's posts about time and ease to fabricate things.
He seems to be uncommonly good at that sort of thing, so multiply the time by 10 :-)
I'm anxious to hear how yours works ... Jim S.
Me too. The Setrab oil cooler installed real
nice today, and it's all buttoned up ready to fly. The POS Earls
fittings didn't even leak (yet). I'm going to
leave the prop pitch where it was on the last flight, which gave me 6300 rpm at
3 psi of boost. I'll try to run 30 inches on climb, and see what the rpm
is.
