Jackson Racing Dual Radiator/Oil Cooler

Here's my latest (and probably last) update.
I sent JR the following note:
I tried 10w40 Motul 300V over the weekend and got the same result [threw the P2646 code]. Note, this does not have to be taken on track for it to throw the P2646 code, this happens after one or two runs through the gears on the highway. This car has always shown good oil pressure so I don’t believe there is anything wrong with the oil pump at 70,000 miles. I believe there is either a defect in the oil cooler/plumbing, or there is a flaw in your design.
This was their reply:
From our testing, we have found S2000s to have low oil pressure as they wear and the pumps get older. If you test your oil pressure at idle without the cooler, you are supposed to have a minimum 35psi. It is safe to say you are probably closer to 18-20psi. In these cases, we suggest running heavier weight, 10w-50 to 10w-60 depending on the wear of the engine. We have found no problems with the coolers and plumbing. In fact, just this weekend our cooler was used in 100ºF heat at Auto Club Speedway for the Global Time Attack. Car operated perfectly the entire time.
I have decided to keep the radiator installed and disconnect the oil cooler lines – mainly due to the $$$ investment I have in installation and trouble shooting. However, I was able to reattach my oil pressure sending switch and was able to observe pressures both with and without the oil cooler.

- Hot idle (@210 degrees oil temp) without the cooler varied between 18 – 20 lb. With the cooler it dropped to 6 – 8 lb.
- 1,000 to 4,000 rpm without the cooler 30 – 80 lb. With the cooler 10 – 40 lb.
- 4,000 to 5,000 rpm without the cooler 80 – 90 lb. With the cooler 43 lb. max. The oil pressure essentially topped out at @40 lb. at 4,000 rpm with the cooler hooked up. (Out of concern for the engine, I did not take the rpms higher but from previous experience I know it will throw the P2646 code due to low oil pressure in VTEC)
if it was one of us that had this problem fine. But there's what 7-8 on this thread alone? How many do you think they've sold in total? 20? 30? That's a pretty bad default rate. I'd love to hear what MotoIQ results were. They should own it. I'm already into this rad for a shit load of money because my lines didn't fit. I will happily ship this rad to them on my dime to install in their GTA car if they film the install and every lap they do with it. I guarantee they don't dare leave the pit.
They havent replied to me yet.
Anyone actually have good results to report?

Just got this email from JR:
"Thank you for contacting us. We have been working with MotoIQ and an industry-leading oil engineer to better explain and help consumers understand the changes that happen with and without cooling. Ultimately everyone will better understand oil pressure fluctuation, especially with the S2000.
We should be able to give you more information in the next week or so with more S2000 specific information.
Regards"
Glad to hear I'm going to get an education about how 60 psi is really 85 psi.

I hope someone referenced this thread while corresponding with JR.
I remember drooling over their catalog as a kid.
