Guys,

Anyone used a linear oil cooling line?

Which is basiclly a aluminium pipe with oil line fittings in each end and machined groves down its length mounted under the car. Used in nascars i am told rather than normal oil to air coolers.

where do you run the line?

it's the exact same principle as a radiator style but just finned on the length by the sounds of things.

if you were really clever you could determine the surface area of either type and see how much heat dissipation you'll get out of both...

LOL not that clever saddly.

I tried to get a pic but no luck yet they come in 3, 4, or 6 foot lengths and have about a 3/4 inch bore and about 1 1/2 OD.

My thoughts were to get 2 of the 3 foot items and install them into a aluminium header tank and turn them into an oil to water heat exchanger by running the coolant from the engine into this headertank whick is about 90 degrees on outlet of the engine. The oil would pass through this first then onto the 2 air oilcoolers before getting involved with the up and down bits. And hope fully get over this oil temp issue for good.

I found that running my fuel return through an aluminium pipe back to the tank has worked well as fuel temp has dropped about 10 degrees ( measured on the black swirl pot )

all sounds like a bit over overkill to me, for what reason can't you use a normal air to oil cooler? Don't the RB26 engines already have an oil to water cooler as part of where the pressure sender/filter bolt up to the block.

I do like the aluminium pipe for the fuel return line though :D

Nope dont think its over kill!

My version of over kill is having to do track sessions in 43 + degrees (without killing engine). So hot now we have to do night session under lights.

Yes RB26 do have an oil to water heat exchanger, but even with 2 x oil to air coolers my oil temp still bumps 120 degrees. Will also allow another 4 litres of coolant which will give the coolant more time out side the engine which can only be a good thing.

they are nowhere near as effective, great for fluids which have a low density like fuels etc but i used one for pwr steering a while back but it did not cool anywhere near as much as a stack type cooler.

    • Hello, sorry for being late to join the discussion, but my clock just died on me.   Ive tried to look at Michaels digital clock repair.docx and it doesnt work maybe the file has expired.   Please let me know if you can re upload it or take some youtube videos to show us how to get the clock installed? thanks
    • I thought that might be the case, thats what I'll start saving for. Thanks for the info 
    • Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.
    • Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
    • My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
