Fresh air duct hose, etc.

[GTBradley]

I'm going to set up venting in my car from the nose of the roadster to the foot box of both sides. I currently have cables and knobs but am looking for the rest.

Looking for 10 feet of fresh air duct hose, waste gates, vent ducts for FFR MKIV.

GT,

Look at the wood working supply houses, they have what you need. Blast gates are available in plastic (ABS) or metal, the vent hose is dust collection type and available in 2", 3" and 4".
FWIW, I made my front vent attachment ducts out of PVC rain gutter to 4" round transition pieces, they fit the brake duct opening perfectly.
12 volt blower motors are available from boat shops or Amazon - look for bilge blowers.

Excellent advice!

Alternatively, you can also use RV dump hose (from Wallyworld, etc.) for the flex air duct hose. I got my waste gates from a local RV parts supplier. They're aka RV blade-style dump valves. I used West Marine 12v bilge blowers for moving the air in traffic, etc.

HTH,
Will

Interesting, so you have 4” ducts and blowers? That would move more air.
I was thinking I should use the high temp hose...

Attwood makes 3" and 4" blower motors at a very affordable price.

Easily purchased at Amazon.

Yeah, I've seen them I just wasn't sure that 4" would work.

I used brake duct hose from the front vent holes, across the top of the wheel wells, then aluminum tube through the wheel well rear panel and then shifted to aluminum expandable hose (like a cloths dryer) over the headers. An aviation guy on Ebay makes nice bulkhead flanges of varying types. There are brake hoses that will take the header heat, but I went with the aluminum. I used long zip ties over the front upper A arms and large metal hose clamps at all joints. I did not put in a shut off valve. I just stuff in a shop rag, or tape over front inlet. I did fabricate two nozzles on the foot well side to direct the air down. It seemed to just blast the back of the dash otherwise. It ain't A/C but it did help.

Quote: "you have 4” ducts and blowers?" - Yes I do . . . Pretty much what Cobra Earl was supplying years ago.

Pictures say it all:

I'm set up with 3" Spectra ducting with Attwood Blowers.
I ran the wires inside the ducts to protect and hide to them.
We also have heat for my wife's feet via a Jeep CJ3 Heater core and a manual valve and choke cable.

When setting up your fresh air venting, it is often best to avoid standard dryer hoses because they lack the necessary heat resistance for an engine bay environment. Many builders suggest using 3-inch high-temperature neoprene ducting paired with aluminum blast gates from a woodworking supplier for a more robust and reliable setup. Additionally, incorporating a 12-volt marine bilge blower is an effective way to ensure consistent airflow into the footboxes even when the vehicle is idling or moving at low speeds in traffic. Properly routing your ventilation is a critical part of ensuring cabin comfort, much like the detailed planning required for residential climate control and airflow systems. Taking the time to select high-quality materials during the build phase will prevent future maintenance issues and significantly improve the daily driving experience.

Ensuring every component is correctly installed from the start is the best way to achieve a high-quality, finished result.

Agreed, I order my hose off of Amazon which is fire rated
