Got A Real Good Idea Here!

[400exJOE]

Ok, we all know how were always looking for ways to keep our high compression, big bore 400s to run cool. Well I might have come up with a winning idea. I am not a fabricator, so redrider-ex
or anyone else that is, listen up. On the back side of the oil tank (side facing headers and front of engine) there is a big flat side. What I'm thinking is why not put like a 4" by 6" heat sink right on the oil tank? Ya know, vents to disipate the heat with more surface area... I haven't thought of how to attach them to the oil tank besides welding, but maybe they could clamp on or something.

[trx400ex]

you mean attach little fins on the oil cooler fins? this seems like it would be alot of work...:confused:

[400exJOE]

i was thinking like 5 or 10 fins that ran across that back of the oil tank. Not tons of little ones.

[trx400ex]

oh, my bad , i didnt know you meant tank, i thought cooler...that might work, but i dont know much bout that...

[Smoker]

Fast to slow runs leave the bike hot, how about an electric fan on the oil cooler for slow runs? Don't know how much a of a difference it would make. They say running high octane fuel helps keep the temp down too.:p

[400exJOE]

What it would do is add a lot of surface area to the tank to the hot oil circulating through the tank could cool faster. More heat escaping means more cooling and lower temps. Take a lok at the super cheesy pic i drew up. The fins on the back of the oil tank are the heat sinks

[400exJOE]

ok, here's what i'm talking

http://www.coolinnovations.com/images/jpgs/products1.jpg

This is a pick of some heat sinks from a company called Cool Innovations Inc. They could be welded on to the oil tank and dissipate a lot of excess heat. They mainly make stuff for cooling electronics, but we could call em and see what they have to offer.

[beerock]

yo they have a way to cool things down, its called a oversized oil cooler.........................

[400exJOE]

i know beerock, but it also cost around $300. These heat sinks would have more surface area anyways. I'm just seeing i peoplethink that they might work.

[TrengaBlaster3]

this could combine smokers idea of the fan wit the heat sinks.

[400exJOE]

now were getting some where. What company makes those fans???

I just finished a J&E 10.8-1 416 conversion with XR400 cam. Haven't even gotten to ride it yet due to the heavy rain in Mississippi. How hot does your oil get in normal riding?? Living in the south, this will be a concern for me this summer. Have you considered that in cold weather with additional oil cooling, the oil might not get warm enough?

Radian HeatSinks

if its cold out just dont put the fan on and itll cool it less......

where is MS are u located?

[Texan32]

I work with electronics every day. The heat sink idea will work. Just remember. However you decide to attach it, use a thermal bonding compound between the oil tank and the heat sind. The compound help transfer the heat over the entire area (not just the welded spots). This compound should be available wherever you get your heat sink.

[400exJOE]

how much would a heat sink cost that is about 5" by 2.5"? What about the heat sink with fans?

[400exdad]

I was thinking about the fan thing the other day. 12V fans come in all shapes and sizes. The heatsink idea is very cool. :p I think it would work too. Maybe the fan could be placed to blow on both? Or perhaps with that much heatsink, a fan probably wouldn't even be needed. Has anyone contacted Radian to see where the heatsinks can be purchased?

I am in Starkville. Close to you??

Wouldn't our 400s get hot enuff to melt those wussy looking plastic fans? IMHO.

["BLAHH"300!!]

VICKSBURG MISSISSIPPI...HERE MAN.....WELCOME...i know some people up on starkville but there all in school....

[TrengaBlaster3]

i dont think they would put those fans on a heat sink if they were going to melt....http://plauder-smilies.com/happy/roflmao.gif

[NJ300ex]

Yes they would. Those heatsinks with fans are made for computers. Do you think that a computer gets as hot as a 400ex. I don't think so.

[TrengaBlaster3]

yeah probably.http://plauder-smilies.com/laugh.gif Youd be suprised how hot computers get. how bout you get off your quad and blow on it. or get a liquid cool kit for your oil cooler.

[worm]

or how about you ride.... the wind blowing from flying through the woods isnt enough? so you want to put a little fan on your quad? usles....oh maaybe the fan would work better ....400s are pretty slow...no wonder you wanted an extra cool it isnt enough....stupid me

[TrengaBlaster3]

http://plauder-smilies.com/laugh.gif yeah i think 400exjoe knows all about slow 400's. gettin beat by a blaster must suck. lol just kiddin around joe. but is that why you needed the 440? we'll see when i get my shee how fast your quad is.....hehe

[400exJOE]

the heat sink idea is coming together. I wrote some e-mails and one guy said that he knows of a heat sink for a pentium thing thats about 6" by 6" or 5" by 5". He thought that attaching it to the oil tank by a bead of weld would work better than what we have now. I just dont know if it would transfer heat that well. What about JB weld? Could we bond the two (the heat sinks are aluminum) using JB in between them and, would it hold up to the heat?

[TrengaBlaster3]

Dont scrap it, J.B. it! i think you should throw on some of them air scoops, hot glue the heat sinks to the oil cooler and get a liquid cooler kit for the oil cooler. i think youll have the cooling down to a science. Dude.. im gettin a shee!

["BLAHH"300!!]

not talking to you 400exjoe...:blah

[Blysster]

Well the idea sounds good but would it last? I mean what about the water, dust, and mud? I don't think those fans were designed for that.. They can bearly handle the dust that's inside the computers..

Oh and they wouldn't melt.. it may sound rediculous but some processors do get hotter than 400exs

[PaRoostR]

For the fan you might try looking for a fan from a liquid cooled ATV. They are vented with a tube (the rest is sealed) and you could run the vent tube into a spot safe from water and crud you could also put a filter on it.


for the people that get into a lot of mud (or don't clean your quad very often) if the heat sink gets filled with mud it will act like a insulator and work agents your initial "Real Good Idea"

[TrengaBlaster3]

yeah i can say unreliable why? can you? im not the one who has to worry about cooling down a shee HAHAHAHA! yo joe i might be gettin a 2002.

[Braff1]

Has anyone thought about taking the oil cooler fan off of a rancher? You might be able o use the rancher's cooler also.
Just an idea.

[400exdad]

TregaBlaster, why are you posting here? How many times are you going to tell us..."dude, I'm getting a shee", or "I might be getting a shee".

[400exJOE]

i have no experience w/ JB Weld, but from what I have read, it seems like it would work in bonding the heat sink to the back of the oil cooler. Let me know your thoughts on using JB. I bet we could do the entire project for under $50. I think it will have more surface area than a pingry's (spelling) oversized oil tank and that means better cooling efficiency. If anyone else is interested in doing this, let me know.

[Pro400EXC]

There is a company by the name of XR'sonly that take you cyl and add bigger fins to it. It looks pretty trick too.

Here's there addres, email them about it.
www.xrsonly.com

[TrengaBlaster3]

hmm.... 400expops im sorry i cant afford to buy an awesome 400ex like you. im 15 years old wtf do you want from me? im just excited that i might be getting a banshee and now im gonna go in my room and cry http://plauder-smilies.com/happy/astrosmiley.gif . i hope your happy!:mad:

oh and the reason i post in here is because i found you guys some heat sinks wit fans in em and i wanted to you help out.

[400exdad]

TrengaBlaster, Yep I saw the link and I thought it was cool. Then you talked about "unreliable" this and that. In other words you think a "Shee" is all that and a bag of chips. With everything you say you have on your Blaster... You could have had a real quad!!! :)

I think the heat sink itself would do a great job even without the fan. Add some air scoops like Tinner made to help out the air flow and it would work like a champ.. I don't think I could put heat sinks on mine though,,I got so much crap crammed into the front end on my quad along with the different bend of the powerbong it looks like the back of sanford and sons truck..

[TrengaBlaster3]

i didnt say anything about unreliable, EX-CITING 300 said that when i said that i might be getting a banshee. and no i couldnt have gotten a "real" quad ( i guess that means 400ex??) cuz my dad bought the blaster and i bought all the stuff for it over time. i didnt just go buy a blaster wit cash and get home and order $2000 worth of stuff.

OK,,,lets not have ta put this post to rest since there isn't a flames forum anymore...let's play nice guys and get back to the subject...:D

[400exdad]

You're right Rico. Sometimes when folks post on here they are actually jabbing their friends/forum sparring partners. I tried to go back and read the posts and make sure I was reading correctly, maybe I wasn't. I guess I owe TrengaBlaster an apology. Sorry Dude. :o

And he owes you an apology also..:D :D

[doctor_915]

Has anyone thought of using Hemotite heat sinks? Or even a Hemotite screen or something in the oil cooler itself? Sounds crazy but I am just tossing up an idea here.

[TrengaBlaster3]

sorry, from now on ill stick to the topic.

[Wheelie]

The idea of more cooling for the ol' EX has been a quest of mine for some time now. I've often wondered why Pingry's doesn't put a few cooling fins on their tanks, that might drop the temp another 5-10degrees.

I've also looked at numerous oil coolers on other Honda quads, the only one that might work is (don't quote me on this) the oil cooler on the Forman 450. The dimensions look close to the same as the 400ex, the mounting is a bit different, and it has one more row for cooling.

Until someone makes an oil cooler than mounts in the stock location and increases cooling capacity a significant amount, I'll stick with the Pingry's tank.

BTW--Does anyone own a radiator shop?? Someone good with cooling fins could take two ex oil coolers and mate them together. With a few small mods, it would still mount in the stock location.....just a thought.

it's good to know that we can work things out!!!!! :)

[400exJOE]

I found this on ebay. Looks just like what I want to use!. It would be enough to make eight 6" by 4.5" heat sinks.

Heat sink material! good quality. 2 pieces 9x12 in size. pulled from some used equipment but still usuable. has some drill marks in it but not all the way through. Radio shack does not carry this type of heat sink. professional quality. works good for linear amps. radios, and any other project that utilizes the need for heat sink material. thanks for looking. buyer pays shipping. size is 9x12x2

["BLAHH"300!!]

yeah that was me man..sorry,, i havn't been here in 2 days'
so all the arguing went on without me....i said the banshee was unreliable...sorry.....:square

[400exdad]

EX-Citing, No prob, it was really my fault. I thought someone was flaming 400's. I was wrong. :huh

Mickey said something interesting other day about pressure drop with a bigger oil cooler. He may have a point. I was all ready to get a bigger oil cooler till he said that. I'm beginning to think that the heat sink/bigger oil tank may be a better way to go. I do think that with Mickey getting more, cooler oil to the top end is good too. Now, if I can only decide what to do??:D

[DieselBoy]

what if you incorporated a "coil" style like they use on the radiators, so when it comes out of the engine, it goes through this coil/radiator style thing, then into the tank? i believe this with the wind would cool it down, and possibly adding a fan.


a large radiator would be perfect

that would be your oil cooler, all 400ex's have the stock cooler. Some people have tried fans others have plummed in a secondary oil cooler. And wow you dug up a 4 year old thread :eek2:

[Pro400EXC]

Wow...

4 yr old thread...

[DieselBoy]

Sorry, I didn't realize it was 4 years old, it was on the first page of the Powertrain section....

[abuckley1290]

i know this thread is old but i found a nice heat sink..its about 4"X2.5" and the fins are about 1.5" long...what do you think about getting it welded on or JB weld maybe?

[xxnightraven73x]

why not just go to your local auto parts dealer like napa or advance and get a small tranny cooler and a small fan for it thats what im going to do in a few weeks

[Iliketogofast]

That would work really good with a fan and a bigger oil cooler.

That's only $2000 worth of stuff? I'm pretty sure that little firebreather would smoke a 400EX :D

[400exstud]

This is actually a very interesting forum!

Does anyone see a bad thing with a small heat sink. Someone said that it could act as an insulator, but what would be the difference between that full of mud or your entire oil tank is full of oil? Either way there wouldn't be much heat transfer.
