Coolant flow

Haven’t gotten around to fabricating one (that is the only option) yet as I’ve been busy fabing other stuff. Temps don’t rise that much at stops or cackling around town at lower speeds to really give it consideration. Rise at longer stops at the most 10° if that. The small doghouse size and fan doing it’s thing may have something to do with that IDK.. I run anywhere between 160°-190° ish depending on ambient temps. I only drive it in about 50°- 85° temps (it takes a little easy driving initially to get temps up obviously but my biggest issue in the cold it the lexan windshields fogging up!) as I have no heat, no wipers, no A/C, no thermostat (no bypass or heater hoses, only a disc equivalent to a gutted 160° thermostat by choice) I run at the track with it too. I’m honestly in good shape now with my pulley combo, the hv water pump, aluminum radiator, and MP 5/blade w/Hayden viscous fan clutch etc.
What radiator do you have? You've obviously planned out the cooling system very well.
