oil cooler idea

[duneracerweston]

Ok this idea got vooked up on the way back from little sahara what if we fabed and mounted a oil cooler/oil tank any ideas are welcome like what all it would take to do ect.

i had the idea in the past about installing both the big bear and clutch type oil cooler. I never tried it, I thought the oil pump might not be able to handle the extra lines and coolers.

87 weren't you also talking about using the reg cooler and one of those tube type ones

 

[87warrior917]

Yeah i was, but i didnt want alot of connections with clamps. More prone to leaking

what about doing a splitter odn the return line and feeding cool oil to two places, head and crank, like one through the valve cover and the other to the crank?

If you split the line wouldn't you cut the oil pressure down?

That and then the oil would flow the path of least resistance, which would probably be to the head if you routed it there.

I was going to put it inline with the oil cooler and make it so it could hold like a extra 2 quarts of oil so the oil life would last longer and I would put it under the head pipe on the frame and make the tank out of aluminum

i dont think our little oil pump would like that

Food for thought:
My semi-educated guess on the Big Bear cooler being OE engineering is that these engines do NOT need oil pressure, so to speak. They need volume. They are roller bearing throughout, no plain bearings like an automobile. Plain bearings rely on pressure to keep the oil film between the crank, rods and bearing surfaces. Plain bearinged engines "float" the journals; they do not actually contact the bearings themselves.

Take a look at the little weenie hole in the clutch cover feed compared to the Big Bear cooler cap/lines... You can only cram X amount of 10W40 through a given orifice... How much of a potential fluid volume difference is there between the two?
I say a lot...

A pretty good idea, IMO. Extra volume is good.
Kind of a semi dry-sump idea. (Dry sumps typically hold several gallons in race cars). Look at a 410 Sprint car, NASCAR, etc. Not exactly the same, or for the same reason, but...

so yal think it would work? im a duner a mx guy and im getting tired of all the continual oil changes and it gets messy

 

[DeadLastRacing]

Kinda like a 400ex?

 

[duneracerweston]

ya or a kfx i just thought it couldnt hurt its just that the oil gets so damn hot the clutch dosent want to pull 6th with 1 1/8th inch paddles

 

[duneracerweston]

this s a mock up of what i was thinking

this is what i was doing to make it slip the clutch

 

[duneracerweston]

Ok so I crunched the numbers and the extra oil tank can hold 2113.92 cc's of oil

 

[duneracerweston]

Ok so I've been looking for a cooler on ebay but were did every one get their coolers? I want the short one that tucks under the hood and dosent show the perma cool 1007 or something real similar but I would like it to be cheap

 

[elwood]

it's a tranny cooler from an autoparts store.

 

[duneracerweston]

I still can't find it under 80 bucks tho were did you get urs

 

[W T HECK?]

check out Summit racing online, they have alot of oil coolers! :tup:
