I'd be more concerned with oil temps and not water temps. The water just helps cool the engine down which in point, is really attempting to cool the oil down. The end goal would be for cooler oil to be run so I'd think if you ran water through the oil coolers instead to cool the water down more, then that's possibly like shooting yourself in the foot since you just made oil cooling even worst..

 

I'm a Noob!

 

wut?

 

Did you clean it out? Did you just run water through it. Also, were you able to find fittings or di you cut and use the factory oil lines?


My oil temps got to about 220F max on a hot day of hard charging canyon driving (300 miles) but I have a 28" Fluidyne oil cooler.

 

I want to know about the single side cooler though. I really like the concept of that second rad in the oil cooler.

 

It was 2yrs ago - can't remember if i cleaned it out . I do remember had to block the bypass .
Used water hose and hooked into the overflow tank circuit . It really does work well - true story ....

 

wat ? I don't run water through the oil cooler that originally came with the car . My car only came with 1 oil cooler - which is still an oil cooler .

 

Could you describe this "sealing up of air leaks around radiator" for me? I live in Austin and I can relate to the epic heat we see here.

 

Ah, so you placed a new stock oil cooler in the other side and used it for water, gotcha. Presumed you had an MT

 

Antifreeze cools the housings. Oil cools the rotors. You need both and should ignore neither with the oil cooling ability to be at least 1/3 of your total cooling. Obviously the radiator accounting for the other 2/3. This doesn't necessarily mean size but rather heat rejection ability. If the radiator has a fan, the oil coolers should too. If everything is done properly, oil and water temps will stay within about 5 degrees of each other with up to a 10 degree differential under extreme use. If the oil temps get farther away than that, the oil cooling is inadequate. If the water temps get higher than that then the radiator cooling ability is inadequate. If they both stay near each other but they somehow hit 250*F, both are inadequate. If you can only get temps up to 200*F then both have plenty of capacity. You get the idea.

 

I will try and find the pic nycgps posted but basically around the edges of the radiator it should be sealed. I used foam rolls from Lowe's that you cut.

My coolant and oil temps are in line but just too hot under high load/high heat situations. Usually they are within 5-10 degrees of each other. I will be running nitrous soon as well and so I wanna get cooling under control during extreme conditions.

 

I found two solutions:

Add-on fan that mounts behind the oil cooler to suck in air over the cooler. Noisy little fcker...

Decreases turn on temp to 195*F and then shuts off after bay ambient hits 185.

 

Mazsport is out of business and the scumbag who ran that company also makes the fan kit which is also not available. Just search Mazsport, you will learn a lot, haha.

 

so what, Im getting 105 Celsius (220 F) oil temp under 97 degrees the other day in traffic.

Im not worry.

 

Well, everything I have read says 220F-230F sustained is pushing it. What are you oil temps in that situation? I'm on my third motor, and no warranty, I worry.

 

I do have an MT - that came with only 1 oil cooler . That is how all JDM MT 8s were built .

 

Bingo. You're not going to get anything lighter than the OE hood anyway.

 

That oil cooler fan is nice.

 

If I'm correct that company is located in Malaysia and the currency converter brings it out to $92 usd

 

Interesting, so all the rest other than JDM built 8's get 2 oil coolers? As hot as I've seen mine get, I beg to wonder, why they didn't add the 2nd one. It would be the 1st time one would have to think, JDM FTL.

 

That is correct, if anyone in central TEXAS wants to order a couple I would be down to split shipping!

 

I was wondering why I couldn't find anything about the company...

 

Actually I think it is more like all of them got 1 oil cooler EXCEPT for USDM which got 2 .

 

I'm leaning towards running one with a fan and one as a 2nd rad. I think that would make a killer combo.

 

/\ the fan is good if you get into a lot of stop/go traffic . Otherwise ....... not so much .
