  1. Big willow track days and temp issues

    With the stock IC I saw 212F water temp on Touge and 230F at Road America. Just one oil cooler though. So still plenty hot for just the stock IC. But yeah this engine runs hot.
  2. Big willow track days and temp issues

    Yes, tracking the car. At the two tracks hardest on brakes in the USA as well (Per Carbotech when I spoke to them years ago, they cited client data), Blackhawk farms and Road America. I'm going to adopt GT3 brake guides and remove the heat shields as well for the FL5. That's worked decent in my...
  3. Big willow track days and temp issues

    Purely fitment. If you look at Jason's setup his coolers are right above the brake duct. So you retain the factory brake ducting. And the coolers are mounted higher in case of a ground impact. Etc. That said it's not as much regret as it's just what I'd do if hadn't already bought the Setrab...
  4. Big willow track days and temp issues

    Coolant temps did not exceed 210F. Ambient was in the mid 70s F. I may install an oil temp sensor at some point, likely next year. Feeding air via the brake inlets and air out the brake outlet holes. I did not plumb any additional inlets or outlets, yet. A lazy version of your setup, if you...
  5. Big willow track days and temp issues

    Revised my setup a bit. I now have Setrab Series 1, 25 row oil cooler on each side, plumbed in series. I also installed PRL intercooler and CSF radiator. I see 70psi of oil pressure at 72mph cruising, very similar to what Jason is seeing for his dual setup and oil pressures. Did an 18 mile...
  6. Big willow track days and temp issues

    Any insight to what the difference is between what you see at the pan versus what the calculated value is on LogR?
  7. Big willow track days and temp issues

    Simply outstanding @siwelnosaj How are you measuring oil temp? I'm going to redo my system and copy much of yours. Simply the most comprehensive and clean implementation for serious track cooling there is for the FL5
  8. Big willow track days and temp issues

    NO SHIT... damn that's slick as fork. The HEL is the same as the Greddy sandwich plate.... good to know! Thanks! @Rhorn - In general, Mishi, G-Plus, Evil Energy are Chinese products, you won't find pro teams using those cores LOL. Setrab and Earl's you'll see pro teams / higher end kits use...
  9. Big willow track days and temp issues

    What do you run, Jason? I asked Gemini, and this is what it told me LOL. Parallel seems to be the way to go. Parallel vs. Series Oil Cooler Mounting There are advantages and disadvantages to both parallel and series mounting of oil coolers, each affecting oil temperature control differently...

    Here's a picture... Up top is a G-Plus 16 row cooler, directly below is a 19 row Mishi cooler. Look at the rows, see how they are "open" all the way to the end tanks? Now look at the cooler on the right, it's an Earl's core. Notice towards the end tank the rows crimp in together. Setrab is like...

    @siwelnosaj - Oh damn, you're THE legendary Jason Lewis, Gridzilla's friend. Damn, I'm gonna copy everything you do then LOL. Saw his video where you and him chatted about your FK8 and learned a lot from it. Thank you so much for sharing in depth info. Your solution is very, very well thought...
  12. Big willow track days and temp issues

    Only going off based Honda's water temp reading, which I thought was actual? It's the Honda Oil temp that is calculated. I do have a Glowshift dual oil temp / pressure gauge I'm going to wire up in time for August track days. Been thinking about my setup, and what I need to revise: - Add the...
  13. Big willow track days and temp issues

    @BuntaTypeR great info, thanks for sharing. I noticed you posted a screenshot of a Mishimoto 19 row cooler. I've compared physically quite a few oil coolers... I've found that Mishimoto oil coolers are the exact same visually (row and fin type, connector type, mounting type) as the much...
  14. Big willow track days and temp issues

    Been testing my setup a bit. Didn't get my glowshift gauge hooked up yet so I know actual oil temp. But on the street I reached 210F water temp doing a run up to 150mph (in Canada). That's the highest I saw on the street. Went to Road America today, ambient temp was 75F. Was only able to get...
  15. Big willow track days and temp issues

    Hey brotha, I recommend you get some wire screen mesh suitable for vehicle usage and cover up the new hole you created for venting in the fender liner. Order one where the holes are being enough to allow air to full through feely but offer enough protection so some freak rock doesn't smash /...
  16. Big willow track days and temp issues

    Nice, good to know. I guess we'll find out. Yeah I know the older gentlemen that ran 2:37 on RE71RS and a 2:34 on slicks with his FL5. He didn't have colling issues at RA, but he told me he had issues and pulling power at Sebring. I'll be driving my BRZ on Sat, then my FL5 on Sun. Doing...
  17. Big willow track days and temp issues

    was imagining being dropped into the planet Venus, but even Venus is only mid 400 C. WTF lol Ports are point back onwards towards engine bay. I'll share more info and data once I prove it out. Currently installing the PRL intercooler and it's more a pickle than I thought since it so yuuge
  18. Big willow track days and temp issues

    So I removed the brake cooler tubes and corresponding brackets on each side for clearance reasons. As you well know, cause your setup is pretty awesome too, the front bumper where the brake cooler tubes connected to them feeds air into the fender area where the coolers are. Then air from there...
  19. Big willow track days and temp issues

    Had the car on my lift and was looking and was like shiiit you know what it'd be easy to intercept the coolant line coming off the transmission cooler and send it to a small radiator on the right side. So that's what I did today. Need a few more clamps and reducers that comes in tomorrow. But...
