Oil Pressure

I've had the Jackson Racing Dual Rad in my car for 3+ years now. As I said earlier, I thought the high pressure at the sandwich was due to Element Tuning's oil system enhancements. This year, it finally dawned on me that my galley pressures were low when I noticed that I only had 40psi in my Accusump.

Yesterday morning, I called Jackson Racing and explained my situation and sent them short videos of my gauge readings. I called them again in the afternoon and answered a couple more of their questions. They were supposed to call me back but so far, they don't seem too interested.

They were concerned that the engine was rebuilt after ejecting the rocker arms but they ignored the fact that the pressure problem existed before that incident but on that they only have my word.

We'll see what next week brings.

I've got the rad out of the car. Not a great test, but no apparent restriction when I blew air through the lines and cooler. JR is not willing to help.

I'm looking at going to an oil to air cooler. The Perrin kit looks good to me.

Any other recommendations that's not JR? I've looked for a thread on oil coolers but haven't found one.

I'm not much help because mine is a franken-cooler. I will say with confidence in my own testing, the Perrin unit is undersized. Assuming thermostatic control, can safely daily with twice the capacity. Double that for dedicated track use.

Would you mind sharing? And please don't tell me the parts are from Abby Normal.

They source their coolers from here iirc https://setrabusa.com/collections/pr...r.v.price.lte=


if you all you would need is to make your own mounting bracket and lines

Ouch. That website hurt my brain. Too many choices. I don't know enough to know where to begin. That's why I was looking at a kit.

I was just going to ask if you were interested in a custom solution. I'm running that 72-row series-1 but adjust flow with a diverter valve mounted under the hood. It was an experiment that worked out even better than I expected.

Just get a decent thermostatically controlled kit. Don't cheap out.

Did you mount that vertically or horizontally? This article on Pegusus' website is informative. It seems there is less pressure loss with shorter tubes.

I guess any of the brand name thermostat units are good?

Precisely the reason for the series-1! One of my goals was to minimize head loss. I also plumbed the whole thing with 12-AN fittings and hoses. The 72-row 'just' clears the coolant fitting up against the AC condenser. I'm quite pleased with my handmade brackets. Added it right to the cooler stack.

@Ultramaroon: Thank you for your input. The more that I read the more I might go with something like yours. Your brackets look better that professional. For me, if I run a thermostatic plate, over capacity should not be an issue.

I'm thinking of mounting the cooler more forward and/or higher so the ports will aim to the left side to eliminate the elbows and 2' of hose. I've read where some folks use a smaller washer reservoir to reduce weight and it would make space to run my hoses.

Unfortunately, thermostatic control alone doesn't prevent over-cooling. They always allow some flow through the cooler to prevent thermal shock. I can't daily mine with any more than half flow through the cooler but it works perfectly for running flat out. All I have to do is reach down and adjust the lever.

I'm already looking at downsizing. The 34 row cooler has a 1.5-2 psi drop and a little more wiggle room on fitment.

Unless there's something I'm missing, I think the 34 row will fit my needs. It's for engines up to 230 hp. Advertised oil pressure drop is 1.5-2 psi. The next size down is a 25-row cooler with a 2-2.5 psi drop.

I'd say it's the sweet spot. Could also copy my setup and cover half of it with something. I've considered doing that with nine but I like having the extra capacity at my fingertips. It's rewarding to be able to stay on the pipe indefinitely.and watch that oil temp never exceed the water
