The cooling is fine imo. The Supercharger is being spun really hard. If the cooling wasn't sufficient then the temps would not recover as fast as they do. His setup heats up fast during the pull and comes right back down post pull to almost prepull numbers. Most PD setups I see being spun within their efficiency range show a very slight increase or even cool down a couple degrees on a pull then heat creeps up when you let off the throttle before it starts to recover.
It's a classic symptom of over spinning a supercharger. The only way to deal with it is spray methanol like many do with X port factory 1.7's cranked way up. If they didn't have methanol the temps would hit 200+ at the levels guys are pushing them to run in the 8's.

Can't compare what cars are doing at sea level.
Tim's X port bolt-on car only made 9-10psi on stock pulley when he lived in your area. When he moved to east coast boost went to 13.5-14psi changing nothing else. So you have to look at it as your car is pulled for 23-24psi at sea level. It's going to make heat fast. Imo the 2650 is only efficient to 18-19psi at sea level with no Meth.

8.3 lower
3.0 upper 18/19psi universal trunk tank 5.5 gal Stewart pump cheap larger PLM exchanger Ambient temp 100 IAT1 100 IAT2 112 runs 8 to 12 over ambient no matter the temp i only logged at 100 but gauges read 10 over no matter temp out side. IAT2 124 runs 10 to 12 over IAT 2 Nail the gas for a run the temp falls close to 10 degrees then after the run it rises 6 or 8 then the exchanger cools it down after about 1 or 2 miles.. sitting park with no airflow for a long while expect to see 165 to 185 but recovery is quick on hwy slow with dyno fans or impossible to recover much a1 30 mph

I use the davies and stock edelbrock in wifes 2300 and stock and Stewart in mine. I tried by themselves and got more flow by using both.

Yes, using stock and Davies. Redoing water system now. In/out of the tank with 1.5"/1" reducer, and 1" ID reinforced two ply Gates heater hose.

On the Maggy 2650 side I just dropped 15-20 degrees switching to DSX’s lid. MAT’s are now 115-125. Was not expecting that kind of drop. Did it for sound and King had to end up adding fuel as well.

It doesn't look like DSX offers a lid for the Edelbrock 2650. You might contact DSX and inquire about it.

I need to ask Mike about this but the Corvette lid I'm using is much thinner then the double hump lid that the 2300 came with for the Camaro. I'm wondering now after seeing what the Dsx lid did (although its billet) if that's why I'm seeing lower IATs then my old Camaro with the 2300 standard lid.
