I'm contemplating mounting my Rad in the rear of my buggy any thoughts, opinions or shit talking about this idea? Would 4 16" inch electric fans keep the engine cool, and would I have to use an inline marine pump to assist the engine pump?

You will be fine with your stock water pump without any assisting from a marine pump. I would think 2 16" fans would be plenty to keep it cool. Just make sure you get more rows and an aluminium radiator helps with the heat as well. Hope this helps.
 
A friend is running the stock water pump, stock radiator, electric fan from a Volvo car because it was free, and no problems.
 
Well I was planning on running 4 16" fans it being a diesel. I can wire 2 each in series to utilize my 24 volt system and it will still only be like running 2 12's in parallel
 
I'll just add keep the filler neck above the engine height wise. Less trouble getting the burps out, or, you could have a filler spliced into the line somewhere high.

Yep. Use something like this in line with your upper radiator hose. I got it from Jegs I think.

Planning on being able to hear yourself think...?
 
Huh? What did you say? I'm not sure if I'm going to do this or not but thinking about it, and I already have one of the in line filler necks off my drag car. :D
 
make sure you use good hose to transport that fluid. I tried to go cheap and got burned! I ended up using the hose they use on concrete pump trucks. bout 10 bucks a foot, but one less thing to wory about. HTH
 
bend up some thin wall tube (.083/.095) to run to the back and then simply use short connector pieces of regular hose, to hook up to the motor and rad.
 
I used 2" PVC. It flexes good! I ran it in the cab though. Wouldn't want to run it in rock prone areas like under the frame. Easy to fix if it breaks! And cheap. No problems so far... Used Summit flex hose at rad and motor.
 
inline filler necks

ON those inline filler caps...
I got one from Summit. It's the Moroso one, and had to order the cap separately. Be advised, the caps all have different psi.

...just something to think about.
 
Yep I ran mine with some .120 wall aluminum tubing......works really well.Just remember the less bends in the system the better.When I first started my buggy I did get up to about 200 degrees and shut her down.I had to add more fluid and run it without the thermostat to get all the air out.I ran it for about 15 minutes today up and down the road dogging it as hard as it would run and the temp never reached 160..........cool!

On broncorob's buggy we ended up just using aluminized exhaust tubing. 1.75" iirc. It bent pretty well on the bender and works very well, plus instead of shattering like pvc..it will just dent. (and you can add clearance dents if needed).

Doesnt the exhaust tubing kink all up when you bend it??
 
i am running a rear radiator and had to run a helper pump to get mine to run cool enough. my lil 22re pump was not getting enough flow to the rear. with a deadenbear pump i am now running nice and cool. i also run a 4 core nascar pull off radiator so the capacity is pretty high as well. if you find its not running cool enough just get an electric pump to help it out.
