Motor temps at the lower range were well under 120, even before the fan. With the R1 fan (which moves a LOT of air), I stopped measuring temps completely.
I do have a race this Sat, which is why I'm looking for recommendations. I'll try out what you suggested again, as the R1 comes heavily recommended, and I'd like to try and make this work.
Try adding timing on the can a degree or two at a time as well. Or find out your internal amp draw as is, then bump it up a few tenths, try again until you get it in the sweet spot. It should be around 150-160 coming off after a main. I have always found R1s like to run at higher heat levels than other cars.
Is this 25.5 VTA, F1, or TC?
