I’d say those numbers are representative...they were logged mid-session just before noon break on Sunday...89 F ambient.
I’m certain the WMI helps, but also the fact that I’m holding back some and not pushing the car 10/10ths is probably every bit as important. My better laps were in the 2:36.xx to 2:38.xx range during that session...and feel I was purposely leaving maybe a second or two on the table.
On the WM ratios....From all that I’ve read...and there is a lot of info available on the topic...the 50/50 mix ends up being the general consensus of “best of both worlds” of cooling and octane...so I’m inclined to stay pretty close to that mix.

Changes since then include BM3, Wagner Comp IC, 300-cell DP, do88 aux radiator, and E30. These should help, but my gut tells me it still won't be enough to bring IATs down on long sessions and everything will still get hot.

Altho, I’m starting to think I should run the car like this on my next track day to see how she does, then decide on meth.
Sounds like we are on similar paths except for your turbo upgrade. Hopefully the E30 works for you. Famous last words and all that but I think I'm going to stay at this power level once I get the temps figured out so hopefully WMI is enough to get it done. I'm looking at the aquamist & AEM setups, not sure which to go with yet.

Yeah not looking to push 10/10ths either, but would be nice to be able to push a bit without the temps skyrocketing. Going to give WMI a whirl, hopefully does the trick. Thanks for posting your data and experience with it - really helps.

No problem. The Snow Performance kit may be worth a look too. When I was researching kits, a local shop suggested that I choose based on the controller that met my needs....the rest of the bits in most kits are all essentially the same. Check this one out..

Since the answer to overheating after a couple of laps on the track should never be to just go slower - me and the mad scientist are going to take it a little bit further than just adding WMI. Another IC swap is in the works - little more to it this time around though...
