P1000 Bilge Fan questions...

[Jshell3]

Have not washed it yet so a little hard to see. Was thinking 1 across top but changed last minute.
Basically two t's. Changed for better strength. View attachment 43885View attachment 43886
This actually turned out pretty decent I was really worried with fan size but it's ok. The bracket is the toughest part obviously but not tough with a welder or a buddy with one lol.

I'm actually going to make this change to mine from a bilge fan..

That's great. I go and do a mod, and then get out done by a better mod.

I'm just sitting here thinking of ways to 1 up you!

I have looked at the bilge fan upgrade and am considering it. I also looked at 6"-8" automotive cooling fans. The flow rating of an automotive fan is nearly double a double 4" fan setup. If some is good, more is better, right? Anybody else looked into this design? If you spend a little more on the automotive fan, you can get one with the same seal rating as the bilge fans.

Also, what are folks in the 5 person machines doing to keep the back seat cool? It looks to me like you need to seal around the back of the engine cover where it dumps into the back to keep from just collecting the heat, even with bilge fans.

Thoughts on either idea?

Thanks,

Casey

I used an infrared thermometer in the back seat area and the plastics are MUCH cooler with the bilge fan running. Was over a year ago so I forgot the numbers.

Lol.. dad is going to add a second under his seat so I just figured I'll give him mine and put in a larger one.

I wouldn't not do it... but I'd have to get a request from the backseat passengers. Front is fine already.

Agreed.. I'm just thinking more about the baby riding back there.

Is it possible to put a bigger fan in, perhaps a 10-12" under the seat @CumminsPusher ? I have a new one at home that I never used and had the idea to use it instead of a bilge fan, guess someone beat me to it lol

I originally measured it out and thought 10" fan would go but I tried and no go it hits the motor because it's got to mount under that center brace for the seat. Bigger is better so I was trying.
Fans are measured two different ways- actual fan blade size and housing size. An 8" fan or 10" housing will fit. Larger will not go without major modifications or the fan not mounted to aim down the tunnel.
There is a ton of air movement with these and they are pretty quiet been very happy so far. I've seen up to a 27 degree drop on the digital meter without use of under seat cover so I believe very effective probably even as much in the back. You can feel hot air coming out by right rear tire

For what it's worth, I did some mock ups using different sized paper plates before I ordered my fan and I came to the same conclusion - a 7-8" fan, with a 9-10" total space requirement is the most you can go.

I've been trying to get time too see if it will work hadn't really had a chance to pull the seat off since I put the heat shield in. I also wondered if I put one or two 4 inch bilge fans in and cut out vent holes in the lower portion of the seat and ran a short piece of duct hose to the fan where it would pull somewhat cooler air from the floor of the cab across the engine? Just kinda brain storming and bouncing ideas around.

These are best pics I could take of install and clearances.
The last one shows angle for pushing heat down the tunnel

We used two small 3 in fans coming into the cabin for heat and the have marine vents so they can be open or closed for heating or cooling with the big fan. I've noticed less dust in the cab with them open while fan is on however it doesn't seem to be much different for cooling either way

This is very similar and doesn't seem to get clogged with dirt or mud. Works very well

 

[WHITEP1K5]

Lol looks like the same setup that I had in mind. Nice job by the way
