Get a yh right and it will allow your low compression turbo to idle with the
best 95 twin carb for a half hr at a stretch without loading up.  Open the
throttle and it will pass a surprising amouut of controled fuel air mixture
for the size of its venturi.  Educated tinkering with its metering rods can
give a smooth flow of power from idle to over 5000 rpm with no problem.  The
fact that it limits ultimate engine output was planned by the engineers to
save the engine from destruction by the owner.  The 150 carb is more
conservative than the bigger 180 of course.  Even a high output turbo can't
pull enough air through a 180 carb to make a beast out of the engine.  Good
performance is about all you can hope for, with emphisis on "good", not

then you better come armed with some facts.  I mean other than you aren't
mechanic enough to make it work as designed.    Smitty
