Motul RBF600 Dry = (312 C / 593 F) Wet (216 C / 420 F)
Endless RF650 Dry = (327 C / 622 F) Wet (217 C / 424 F)
But, the #'s don't tell the full story Fluids have another property that is crucial - compressibility. This was a little blurb from Endless
"With our RF-650 brake fluid being standard original equipment on all Porsche GT3 Cup cars (Yes. Standard equipment from Porsche.), a lot of various teams in the US have been in close contact with me regarding it. Most have never heard of it before Porsche started using it as an OE part 2 years ago. Most of them had been using Castrol SRF.
What these GT3 Cup car teams have been telling me is that they’d put the fluid in the system, bleed it, and then go out on track. 5 or 10 minutes into the session the drivers would report the brake pedal feeling soft. So, they’d bring the cars in and check for air only to find none in the system. The actual issue ended up being compressibility. In short, different brake fluids compress more than others which accounted for the drivers reporting a soft pedal.
The teams tried a bunch of different fluids before realizing they should try ours (reason being they had never heard of Endless and they didn’t know where to get it). The teams tried AP, Motul, and others even I had never heard of, all still ending up with the same issue. Finally, when the GT3 Cup cars ran at the Formula 1 Grand Prix in Canada, they talked to the F1 teams. What they found out is that there are only two brake fluids used in Formula 1; one being Endless. Turns out the Brembo fluid and ours are the only ones without severe compressibility issues."
BAR also runs this exact fluid as well on the F1 cars.
The other nice thing - metal containers!
