Track Day 3/30/18
Evasive Motorsports Test Day Cooling Package
Driver: Dai Yoshihara Data From: Kelvin
On 08.08.2017, we tested the FK8 on track for the first time. The car was tested in stock trim, as the dealer delivers it. Ambient temperature was 66*F in the 9:00 morning session. To our surprise, we encountered overheating issues almost immediately. The test driver reported a reduction in power as laps progressed, stating that a “cool down” lap was required between hot laps to stay out for longer sessions.
In need of a immediate solution, we partnered with Greddy Performance and Koyorad Radiators for an oil cooler and radiator solution. On 09.15.2017, we tested a prototype Greddy intercooler and oil cooler kit and intercooler for the FK8.
In session 1, the car was run with Greddy intercooler and no oil cooler as baseline. Session temperature was ~66F light dust, low traffic. Similar results to our initial test, the ECU pulls power as ECT rises, roughly after 2 hot laps. However, there was a lower per-lap delta in ECT vs our original test but this is likely due in part to lower ambient temperatures. IAT was an average of 94~99F. Oil Temperature was recorded at a high of 270F. Due to rapidly increasing ambient temperatures, we chose to add the oil cooler immediately instead of another stock baseline data set.
In session 2, we reset the Infometer data and added the Greddy oil cooler. Ambient had risen to ~73*F, clean track moderate traffic. Same delta in ECT as the morning(~15F) slightly lower average despite a higher IAT average of 104~106F. Oil Temperature saw a significant improvement with peak at 254*FF. The car was able to a full session, 6 laps, without the ECU going into safety. A third session in similar conditions yielded the same results. Ambient ~85, IAT Average 106*F, ECT average 199, peak OilT 254, 5 lap session.
We ran the last session in the hottest condition. Ambient temperature was ~89F. IAT average rose to 114*F, ECT average rose to 209*F, peak of 214*F. The car was noted to have lost performance after one lap. Oil temperature peak was recorded at 256F.
On 03.30.2018, we tested the complete cooling package. This includes production samples for the Koyorad Radiator and Greddy Oil Cooler Kit. The 10:00 session had an ambient temperature of 68*F, most similar to conditions when the car was run stock. 9 laps were done without any issues. There was a peak Oil temperature of 257*F, peak water of 216. we received similar results throughout the day, never once running into any issues. In the afternoon during the 1:00 session, with an ambient of 78*F, we ran the full session, 8 laps. No power loss reported.
I’ve attached a data plots with information pertaining to what was written above.
Fig.1 compares the morning baseline(yellow), laps from the following two sessions with oil coolers(blue and green) and the lap from the afternoon for comparison(Red). From this plot, you can see the effect of the oil cooler on engine coolant temperature as well as its limitations as the ambient temperature rises throughout the day.
Fig.2 plots the stock 9 lap session against the 9 lap session with the cooling package. Red is stock, green is with cooling package. Most notable here is that even with “cool down” laps in between, the temperature peaks for a stock car continue to rise as a session progresses. With the cooling package, you can see that the car can be run consistently with out the need for “cool down” laps. You can also see that the temperature max remains consistent unlike the stock configuration.
Fig.3 shows peak and average comparisons between a stock car and the complete cooling package. Peak Oil Temperature was measured at 257*F for the session. There is unavailable Oil Temperature data from the initial test day but, the data from 09.15.17 shows the oil temperature will reach 270*F within 3 laps.
Fig.4 plots the ECT from the hottest session of the day. You can see the consistency of the temperature here, despite being driven hard for the entire session. Peak Oil Temperature here was measured at 273*F. While this is high, this is after 8 laps, considerably better then stock where it reached 270 after just 3 laps in cooler conditions.
A better flowing intercooler will help bring more air to the radiator. An oil cooler will lower the overall temperature of the engine as a whole, but has its limitations. A bigger radiator will increase the capacity to cool the engine directly. The more power you make, the more heat you will generate. Regardless of whether the FK8 platform is believed to overheat from the factory, these are solid recommendations for any car that sees regular track time. The data provided shows that the products function as intended.

because that looks like pure sex and it's functional!
