Where do you take pipe pressure from?
« on: May 10, 2011, 07:49:12 PM »
From the hot (front) section?  From back in the baffle section? Does it matter?  How do the external vents get configured so you can fuel the plane, etc?

Is there any downside to running pressure? (for instance does the pressure fitting tend to come unglued from the pipe, etc)

Hi mate,
  I have seen the pressure pipe entering about halfway down the divergent cone and obviously facing forward to stop getting fouled up so easily.

Cheers.

Steve,
Many (including myself and Randy) will say that pressure in not necessary, and can only complicate the issue. Least of all, you do not want to drill your pipe as only special hi-temp epoxies will stay in place. If you want to play with pressure, swap your pipe with one that has a pressure tap built in it from the manufacturer.

I was assuming that the 'pipe' was a full length carbon fibre and epoxy here, is it?

I have seen mousse can mufflers and MVVS mini pipes with pressure fittings on them that can be tapped or aluminum welded in place.

Do you still use a uniflow vent and if so how would you hook it up?
Thank you
Dwayne
