Default everyone should smoke!

Smoke -ON-

4-pipe exhaust with injectors in 3 and 4.

I have a bit of a pieced together system... an old tank and pump from Smokingplanes, smoke injectors and a needle valve from Smoke System Helper, hose from NAPA, fittings and such from ACS, SS lines from VANS, and most excellent quick Jiffy-tite disconnect push lock fittings from JEGS...

here is the basic layout in the baggage compartment:

after testing the setup I removed the baggage pan to layout structural support:

back together:

here are the injectors:

Default Oil and oxygen

Nice smoke generation. I noticed your set up and that you have the Oxygen bottle really close to the oil tank......not a good scenario if you have a leak, fire etc. ?? Nice looking clean installation.

Great installation. Marvin is a great fellow to work with and has a lot of expertise on these systems.

I too have mine plumbed into the 3 and 4 exhaust system on my 4 pipe Vetterman exhaust. It works fine.

See ya at Oshkosh. I hope.
