D3PE C7 Brake Duct Oil Cooler System with Test Results!!
As some may know, we have been waiting to test our newly designed C7 Brake Duct Oil Cooler System. After a failed fuse box at our first track rental, some crazy weather, and scheduling, we have finally hit the track to get some results!
Our original thread:
https://www.corvetteforum.com/forums...velopment.html
Test Vehicle:
2015 C7 Z06
D3PE Procharger package with D1SC (690whp) with vertical front mounted intercooler (4.50" thick!!)
LMR 160 Thermostat
R Compound tires
Test Facility:
Texas World Speedway
The first test session with the full OEM cooling system was done at 11:30 am in the morning, ambient temp was at 78 degrees, during this session we witnessed a max oil temp of 289 degrees and an engine coolant temp of 261 degrees before we decided to pull of the track early to let the temps come down. At this point the cars fail safes still did not come on and temps were still rapidly climbing, after only making it a quarter way through lap 3. The car was limped into the pits and we removed the factory system and installed our oil cooling system.
First session peak numbers (STOCK COOLING):
By the time we made it into the second session, it was 2pm and the heat had rolled in, ambient temp had risen 9 more degrees to 87 degrees with a storm fast approaching. We decided to have Sean our driver increase the pace and try to burn the engine down in the same time frame of 3 laps. During this session we reached a max oil temp of 275 degrees and a max engine coolant temp of 239 degrees, that's a 14 degree drop in oil temps and 22 degree drop in engine coolant temps with 9 extra degrees ambient and harder driving!
Second session peak numbers (D3PE OIL COOLING)
Side by side comparison, notice how much more rpm is used in the second session
We are very happy with our results, especially considering our test car had a 4.50" thick intercooler up front while making 700HP! With the use of a stock blower these results should be even better since there will be a lot more air flow to the radiator!
Here's more info about the system:
Benefits of the system
- Utilizes dedicated air flow path within the new brake ducting, this prevents heat from the oil cooler from being transferred into the other cooling heat exchangers
- Removes the strain of cooling the oil with the radiator system, therefor increasing its efficiency
- Built around a proven Setrab oil cooler, one of the best on the market!
- Block adapter has built in thermo-valve allowing oil to bypass cooler to bring to, and maintain, proper oil temps when below 180 degrees
- Hoses are all premade, ready to install, AN reusable series hose kits
- Allows removal of complete factory water to oil cooler system
- Full system comes standard in black finish for a stealthy install
- Works on both Z06 (LT4) and Stingray (LT1) models
Full kit comes with:
- CAD designed CNC LT series engine block adapter with built in 180 degree thermo-valve and o-ring sealing
- CNC billet QDC oem water to oil cooler hose delete kit
- OEM GM Block coolant plug kit
- Setrab oil cooler
- CAD designed aluminum brake duct kit (black finish)
- Pre-made AN hose kit
- All needed hardware
We are now taking pre-orders for the first production run, orders will start shipping 6/20/2016. Retail will be $1399.99 plus s/h for the full system, anyone who preorders will receive 5% off and free shipping to the lower 48 states!

Awesome! What happened to brake pedal feel and temps particularly at the driver front?

Looks like you don't need the 160 thermostat as coolant temp was far higher than that number or the stock thermostat.

Second one started at way lower oil temp.
Though not sure it matters seems to level out. But could be less rpms at that point.
Better to see average of full all day session from couple track days. With and with out..

The first session the car was idling in the pit lane as on the first lap of that session a Porsche scattered on turn 2, so we had to pull back into the pits and wait for 10 mins, then we started again and did 3 more laps. All of our testing was done within the same day, in a perfect world we would have tested at the same temperature, driving, and everything and I know our system would have shown even better numbers, but unfortunatly temperatures change and parts take time to change ( R+R of the factory EOC on the ground after cooking the engine on the side of the track was not the highlight of my day).

Wanted to add in that this is a 100% drop in system, no cutting of anything and can be reversed at any time! Make sure to get in on our discounted preorder pricing!

I've read this reasoning a few times before and I'm not sure I agree it's a trivial temperature change. The ambient air temp through that brake duct may normally be 50-100F. If you're blowing through the oil cooler first, now you're increasing that air temp to say 200F or more (the outgoing air won't be the oil temp exactly but clearly higher than ambient and oil temps can go to 300F). While the brakes may be 1000-1400F, the 100F cooling air differential may be significant when the brake cooling is already an issue.
