I know maybe there isn't a definitive answer. I also know that the SI bumper is different than that of an FL5 BUT if the grille gets switched out to that of a Type R with the brake duct openings, is there anyway that this fits into an FE1 Si?
I’m very proud to share the official release of my WOT Performance Dual Oil Cooler Kit for the FL5 and DE5!
This has been a project a little over a year in the making. A ton of effort has been put into this project to ensure that #1 it is the best performing kit available, and #2 that it does so without you noticing.
The goal all along has been to create an uncompromised solution using the best components. Unrivaled in performance and form.
Cutting the bumper or placing coolers in front of the radiator were easy solutions, but not at all optimal ones. I aimed for a kit that is stealth and doesn’t require cutting the front bumper. I also did not want a cooler to sit in front of the radiator and block airflow, or worse yet, feed it superheated air. I wanted an uncompromised solution.
As you can see in the pictures, my kit replaces the OEM brake ducts with our own custom designed dual ducting system. These maintain feeding air to the brakes per the OEM design, and additionally, they provide the two oil coolers with plenty of focused fresh air.
An obvious question is, “Does this cause issues for the brakes?” Delicate care was taken in the design process to address this, but we wouldn’t really know unless we tried it out. So, track testing was done on three separate track days ranging in ambient temps from 62°F up to 101°F. Beyond my own expectations no delta was observed in brake caliper temps when comparing the WOT ducting vs the OEM ducting! Brake temps and performance were identical when compared to sessions where only the OEM brake ducts were used. This was incredible! My rationale for this result is that the OEM design is an indirect system that is not completely efficient to begin with.
As can be seen in the provided graphs, the oil cooler kit performed amazingly. Oil temps were reduced by 35°F and coolant temps by 30°F! Massive game changing improvements. Oil temps were collected using the physical sensor I have installed in the oil pan, which is measuring temps post engine and pre oil coolers. Had I measured post oil coolers temps would be even lower! The oil used in testing was Pennzoil Ultra Platinum 5w-30. Additionally, the kit adds approximately 1.6 quarts of oil to the system which helps to share the thermal load.
Oil pressure with the PWR single pass oil coolers was observed to only show a drop of 4-5 psi when at a similar temp vs with no coolers. In an absolute sense though the psi was the same at the end of the 20 minute sessions given that the oil did not get nearly as hot with the coolers installed vs without; pressure was more easily maintained with the lower oil temperature.
In summary the WOT Dual Oil Cooler Kit:
- Has been shown to reduce oil and coolant temps by 35°F and 30°F, respectively
- Uses top of the line components: PWR cores, Raceflux lines, and HEL thermostatic sandwich plate
- 3D printed ducts, CAD modeling via Casale Design LLC who also designed the Spoon Thill 24h bumper vents and is an aerospace engineer by trade
- Retains OEM brake function, No brake cooling issues
- Requires no cutting at all of the bumper
- Does not obstruct airflow to the radiator
- Uses exit vents in the fender liner, angled outboard to evacuate hot air out (no issues with front end grip or unusual tire wear has been observed)
- Maintains OEM wiper fluid function via a relocation reservoir that reuses the OEM honda motor, plug ‘n play
- Maintains easy daily driving oil warm up via 180°F thermostat in the sandwich plate
- Uses 10an Raceflux lines which have a lifetime warranty against leaks with the fittings
- Minimal drop in oil pressure vs OEM
All kits will be built to order with an estimated 4 week turnaround time. Cost is $2100 USD shipped within the USA. $1800 for the DE5 as it does not require the ducting, they can use their front bumper vents. Willing to ship internationally as well. No other vendors will offer this kit.
