All,

I am curious how the Sniffle = valve on the=20 cont io550/tsio550 works.

It seems to be a check valve = but if you are=20 normally asp

the manifold pressure would be = less than=20 outside and if you are

turbocharged the manifold would = be=20 higher.

This would mean a different = valve in each=20 situation, yet

the lancair store only sells = one part=20 number.

What is the story?
