Tracking car hard in hot climate

It looks like it was the CSF radiator. I put an OE BMW radiator in with 50/50 water/coolant + water wetter, and tracked it all weekend. Granted, it was cooler, ambient temps in 40s-50s F, but water temps totally stable in the 170s, never needed nurse the car at all.

I made the same switch CSF to OE and been much happier. I cant believe these CSF units still being sold.

Wild to me that every person that's been with this platform and gone there and back with it all say don't go away from OEM radiator and still ppl do... Now we're also at the point where OEM radiators are not from Modine anymore which is sad, not sure if anyone has metered use with the new Modine "owner company" (name transfer or whatever.

In terms of oil temps, new OEM oil cooler and surrounding hardware new OEM is known to have drastic improvements on lowering temps. You have a 24 year old platform with 24 years of use that many times was not you at the wheel or underneath it to care for it. I see oil coolers as the only real improvement over OEM and id never give my money to CSF. d088 is where id go for a like OEM replacement with increased capacity and a lower weight penalty.

The only other options that I've seen on cars that see dedicated track duty (this means wheel to wheel race cars not time attack), is PWR. These cars do not have AC or anything obstructing the frontal area of the radiator.
