Removes the factory oil cooler from next to the catalytic converter and relocates a 10-plate oil-to-water cooler behind the radiator fan.
The oil cooler adapter has an optional port for oil temperature sensor relocating so you can accurately monitor the engine oil temperature going into the engine using the factory electronics.
Note, the kits include the water lines for the radiator to oil cooler and oil cooler to water pump connections. In the beginning we will be supplying hose pieces and couplers to build your own hoses. Meanwhile, we have contracted a hose manufacturer to private label manufacture a molded hose specifically for this application. That has a long lead time, so if you need a kit now you can order with the build-your-own hoses, or if you want to wait a couple months you can order with the custom molded hoses. Please allow about a week to build the kit as this new product ramps up.
Enhance cooling with a Dewitts radiator and 170F thermostat.
That's actually a customer's car. It was working well during an HPDE down in Florida but other car issues cut that test short. We tested the cooler a lot last summer in a 700hp NA Stingray. Andy Pilgrim flogged on it at M1 Concourse in July heat and it kept oil temp in check.
Jason, how does this improve on the stock oil-water heat exchanger? When people overheat, they're near max water or oil temp at the same time. Curious how this gets more heat out of the system. It seems like it may just exchange heat between the coolant and oil better but that may not solve the issue. Is the benefit just getting it away from the cat?

I believe our 10-plate design is more efficient at exchanging oil temperature into the water. Yes, a big part of it is moving the oil cooler away from it's stock position an inch away from a 1200+ degree catalytic converter. Water can be more effectively cooled by adding a Dewitts radiator, and especially by adding the TIKT heat exchanger system and getting the stock heat exchanger out from in front of the radiator.
Does this work if you have the GM secondary radiator kit installed? Do you need to unhook the oil lines to drain the oil during an oil change? Have you written up install instructions?
I trust you guys to have validated that it doesn't affect the oil pressure so I hope it's a non-issue for warranty purposes. I'm interested depending on LOE to install and maintain.
Looks like a nice product but in my mind, keeping the oil and water 'linked' in this fashion is not the way to effectively reduce the temps for either.
We already know that the thermal capacity of the water radiator is marginal on these cars. Dumping the high heat oil into the mix was one of the errors GM made, and even with your 'plate' type oil/water cooler the cooling pathways remain linked. Far better imho to separate the water and oil cooling into distinct components.

Yes, it works with the secondary radiator kit. The vehicle pictured has it on there. You don't need to unhook the oil lines during an oil change if you are changing it regularly.
We have tested on track and oil pressure has been sufficient.
Has as anyone tested this on the track? I am willing to give it a try and report back results. Jason, can you make me a deal on one of these kits plush the relocation harness?

Yes, we have a 427 LT1 Stingray and 427 LT1 Grand Sport that have been doing track days and oil temps have been excellent.
Those coolant hoses going to the green anodized fittings, are they cooling each individual brick? If so, is this a conversion system that is sold as a bolt on upgrade or something?

Jason, this is the supercharged Z06 section, so your experiences with normally aspirated engines may or may not apply.
Katech's revised oil cooler may transfer more heat from the oil to the main cooling system radiator, but what a few people have asked, and you have not adequately responded to yet, is whether this is of any real benefit, since both cooling systems tend to be overworked already under hot track conditions in their stock configurations. This would suggest that that transferring an additional heat load to the primary engine cooling system wouldn't gain much, if anything.
Logically this kit should help because the oil to water cooler is relocated from an inch from the catalytic converter to behind the radiator. This would reduce heat from the cat heating up the oil cooler. This is similar to Viper setup. I would like to see some PDR data or even a photograph of this helping. Since I don't think it can hurt, I may just buy it and test it myself.

I should have paid more attention to which section it's in. We do have a couple Z06s running this cooler also. One got some track time last year, but not a whole lot. No oil temp issues. It came back this winter for a TIKT heat exchanger system so any further testing this year will have fixed the primary engine cooling system issues.
