P1000 Bilge fan

[Dordon]

I know this has been discussed before but what would be the best and quietest for eliminating heat 2 3" bilge fans or 4" bilge fan or a 8" radiator fan, I have seen everyone using different kinds also what brands are recommended. Thanks everyone for the input.

It's all a preference to you just make sure it moves enough CFM that is cubic feet per minute for those of you in Rio Linda.

I have a 4 inch bilge fan under my seat that's been there since 2016 pointed directly at the exhaust manifold and it has served me well. With the wife that is. As they say happy wife happy life

Originally I installed a 4” bilge fan installed like the DEI kit that sucked hot air from under the seat and then blew said hot air out the through the skid plate through dryer vent tubing. Worked well, but started making noise then ultimately blew the fuse. Checked into problem and found bilge fan distorted from heat and the impeller was locked up. I removed the whole setup and installed an 8” spal fan blowing air back over the exhaust headers. Works great now.

Here's my recent post. The radiator fan is pointed across the exhaust headers and is quieter than a 3" bilge fan.
I do think it's a matter of preference.

P1000m5 - What did you add to/do with your Pioneer 1000 5 today?

Not the final version but this is what mine will look like.

As for the fan I used, google:

7" inch Black Slim Radiator Cooling fan 800 CFM Mount Kit​

The 800 cfm is a lot more than the 3" bilge fans, but it isn't as directed as when using ducts.

I rigged a bracket for my 3" bilge blower and angled it at the exhaust header. Flip the dash switch and seat instantly cools down.

That'll work, no doubt, but it looks like you have the blower mounted so the intake is at least partially obstructed. Best if you can keep obstructions at least a fan diameter away from the end of the intake, more is better. The goal is to have laminar smooth flow (no turbulent air) hitting the fan blades. They will be more efficient, move more air, and be less noisy as well.

Air flow is a whole 'nuther science, and real world testing can show unexpected results. I tested my installation using a hand held anemometer to measure exhaust airspeed with the blower in free air. Installed it, first picture. Then thought I'd "improve" things by cutting off the intake size reducer. Originally I measures 35 mph at the exhaust side. After cutting off the intake "restriction", that was quite unexpectedly reduced to 30 mph. I screwed up. I did order another blower though, so I'll fix my screw up when I have time.

I got a dumb idea, this should work better! NOT!

Mom caught me with a hand-held anemometer as I tried to measure flow.
Still beat me horribly.

Air, Air, it measures AIR speed!!! Not pee flow!

I think from now on, I'm just going reply @JACKAL and let him finish my reply on posts like these. Thanks @JACKAL!

@Smitty335 . . . okay, now I'm confused (which in retrospect is not all that unusual I guess), but I went back and didn't see a post, comment, or anything else from @JACKAL in this thread. Are you connecting with him via some sort of medium or??

Trying to decipher Smittyisms is an effort in futility. Not sure what the question is being poised, assume it's bilge fans? Anyway, my posts on all these issues go back to the years 2015-2016. Once I dealt with it 6 years ago, I tend to not regurgitate the subject unless asked. I'm not the Pioneer or expert just one of the first handful here to do it and document with pictures.

The general consensus is the heighest cfm of "directed" air flow blowing onto the engine headers and flows beck and out the passenger side, say 15-20 degree angle to right rear and slightly down. The fan brands, many have a favorite. Some blow so hard it sounds like a shop vac under you seat. I had good experience with the Atwood 450 cfm 4" fan , you could hear it running but also could tell it was moving the hot air from rising straight up to the seat. Got mine off Amazon.com.

Here is my bilge fan installation, literally from 6 years ago....

I ended up getting about 1/2 my switches today, enough to play with in setting up the jumper lines for the whole set. What I have pictured below is incomplete (using two 4 switch banks instead of two 6 switch banks*) but serves the purpose for now in demonstrating on setting up the various...

Here is what I did afterwards to seal everything up.

I couldn't get a good picture angle on the fan. It isn't obstructed but from the pic it would appear it is.

It was 88 degrees today and my first good test of the 7" under-seat fan install I posted above. Worked like a charm and the fan was nice and quiet. The better test was yesterday at 88 when my son spent several hours tooling around with a passenger in the back seat. He's 6 feet tall and a big guy. After the trip he said he felt the heat from above, not below, and was very comfortable.

One thing I hadn't mentioned - I use hunting seat cushions (Wally Mart, Cabelas, S-Warehouse, etc.) on the back seats when adults are riding. I can't remember who posted about this, but it changes the backseat experience for adults. Your knees don't bump up by your chin.

I know, pictures or it didn't happen. Please spot me this one unless you're going to make every adult post photos of their back seat experience. Peace out.

 

[Jankyeye]

Back seat experience could be interpreted a few different ways…. May want to clarify

I agree. Two great, cheap mods
