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.
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...
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?
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...
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...
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...
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)
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...
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...
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.
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.
