We have lots of long duration turbo
experience with choked cylinders that has given us good results.
Not sure there is a problem that needs to
be addressed and I don’t know how not having the choke solves the problem
that is not presented.
It is possible to wear out the choke
rather rapidly by not having sufficient full power fuel flow.

Subject: [LML] Straight bore vs
choke
I recently ran across the website for Chuck Ney Enterpreses
(http://www.chuckneyent.com/) and
read where he advocates straight bore cylinders instead of tapered, or
choked, cylinders. I'm assuming the engine manufacturers have good
reasons for designing taper into their cylinders (variable temperature
expansion characteristics over the length of the cylinder?) Mr. Ney, on the
other hand, claims a vast amount of experience indicating better performance
and longevity by boring the cylinders straight. I know we have some very
knowledgeable engine people on the LML so I'd like to get their take on
straight vs choke.
