J'EN Custom Manifolds
If the manifold you need to complete your installation is not available off the shelf then we can make one for you.
From simple gas flowed 90 degrees manifolds in 19mm or 22mm tube to complex swan neck manifolds with built in side and down thrust, we have the manufacturing expertise.
We understand that it can be difficult to know exactly what dimensions our engineers need to manufacture a manifold so we have created some pdf files for you to use. You can either use them as guides or download them, print them and return them to us completed.
For Swan Neck manifolds - to convert side exhaust to rear exhaust, use - swan1.pdf and swan2.pdf
For Rear exhaust manifolds use - rear1.pdf
For 90 degrees manifolds 'cranked' (as per example below) use - 90bend.pdf
Please take a look at the other examples below and our Customer feedback.
Custom Manifold Examples
|Swan Neck 1|
'Swan neck' (side to rear) manifold
For an upright mounted engine in a delta
(Paul Brundrett's Rapier)
|Swan Neck 2|
Fred Cooper's 'Swan Neck' setup
|Down Under 1|
Richard Norris' Moki + manifold, connects to a quiet silencer inside the cowl and airframe.
90º but 'clever' so that the outlet goes into the centre of crankshaft (so pipe or silencer stays central in (or outside) of the model - making balancing easy!
On this example, the engine's side thrust was also built into the flange - that's why I call it 'clever'!
|Down Under 2|
90 degree, side thrust and down thrust, centring pipe in mid fuselage
Laurence Peake's Mistaken Identity
Custom manifolds (and silencers) for double engine setup.
New for 2006; water cooled manifolds for marine use (also with 'tilt' - in degrees)
