A new Skymaster Owner enters the forums

Hello Jerry. What a nice 337 you must have!

At 17.5k, I ran 2450 but was getting more like 29". This was a very hot day, even at that altitude air was still in the upper 40's. Should I see higher MP on a colder day, all else being equal?

Another question for an experienced owner - what does "bootstrapping" mean in reference to the twin-turbo pressurization system? This is a new term for me.

If your throttles are full forward, you should have no trouble getting MP higher than 29" at 17.5. You have a significant induction leak if you can't.

Bootstrapping is easier seen & heard than explained:
