  1. FL5 vs. FK8 brake cooling

    Awesome, I wonder if that deflector will work on the fk8
  2. FL5 vs. FK8 brake cooling

    Good to confirm it really is just bigger ducts, since the marketing claim was something like 140 F lower temps after 5 laps. But I imagine more air can certainly do that.
  3. FL5 vs. FK8 brake cooling

    The FL5 marketing literature suggested that the FL5 brake cooling was superior. Does anyone know what they did differently on the new model?
  4. Overheating & What You Can Do To Stop It

    To clarify, it seems the FL5 water pump could probably be installed on the FK8. This would come with a different water pump pulley, which would increase the speed the water pump is driven at. Just bumping this, it seems like really good bang for the buck because more water flow means lower...
  5. What parts from FL5 will fit FK8?

    I'm wondering about the: radiator water pump/water pump pulley (the water pump pulley is on a faster ratio) seats
  6. Overheating & What You Can Do To Stop It

    Can a different water pump pulley be installed on the FK8?
  7. options for CAN bus decoder that output to a phone?

    I'm wondering what other options there are besides the AIM SOLO 2 DL?
  8. Oil cooler questions?

    Thanks for the pictures, links, and great documentation. Do you know if this style hook up for the oil cooler sends the oil through the filter first or through the cooler first?
  9. Oil cooler questions?

    With all the current side mount oil coolers (HKS, USR, etc.) does the oil go through the filter before going through the cooler? Is the stock oil pump, that is meant to pump oil through the filter, strong enough to pump through the cooler? I guess I'm asking gallons per minute. How many GPM...
  10. Overheating & What You Can Do To Stop It

    Got it. Just wondering, did you install an oil cooler? (wondering if that is the comparison for the next track day) Also, it's interesting to see the water temp get so high as well. It makes me wonder if the front of the car can be opened up any more than it is (more flow than 2020 grill by...
  11. Overheating & What You Can Do To Stop It

    Awesome, thanks! I think the gain during the fastest lap is probably the most relevant and it looks like you went from 242 to 257 in 84 seconds. (red gauge in the video on the right, correct?) This is about 80% of the heating described in my long post, so maybe overheating at a rate of 10 kw or...
  12. Overheating & What You Can Do To Stop It

    Thank you, I haven't followed as closely as I'd like. Do you know in your data how fast oil temp goes up over a lap? I'd be happy to redo the numbers. I know others have posted oil temp vs. time as well, I'll look around.(of course it only helps if they have the pace)
  13. Overheating & What You Can Do To Stop It

    I think we can make some basic back of the envelope calculations to learn more about CTR overheating. I found a great video. It’s a lap around sonoma raceway with a lap time of 1:55. That’s quick enough to overheat. in 123 seconds, the car goes from oil 237 water 204 to oil 260 water 219...
  14. C&R/PWR Oil Cooler Kit Development

    The problem of overheating is so persistent, it seems like it would be best to do everything that could be done. That is, my wish list would be: dual oil coolers with shrouding that dumps the air into the wheel wells after it passes through the oil coolers This may be a silly question, but at...
  15. Overheating & What You Can Do To Stop It

    I was just thinking simply more is better, what are the cons? (complexity?)
  16. Overheating & What You Can Do To Stop It

    Great write up! Some are running two oil coolers, perhaps this is something that should be added to the write up because if one oil cooler is the first thing you should do, then the 2nd might be another oil cooler.
  17. Jeff's build - for occasional light track use

    Thanks, that makes complete sense. Looking forward to hearing more!
  18. Jeff's build - for occasional light track use

    Just a thought, that could be 1-2 psi low in the front for your tire size. You'd be able to tell with a pyrometer or by looking at the scrub on the side of the tire. Rear should be fine.
