Today it was 90 degrees out and when not moving the a/c was luke warm. Once i start moving it cools down again. The fan is working as is the compressor.

Has any one been running a supercooler in warm weather and can you verify wether or not this is happening to you too?

 

I'm Just curious as to the connection one could figure exists between the super cooler and the air conditioning unit?

 

The question comes from the fact that the radiator I chose for the design is a big as the radiator and sits infront of the radiator. This would obscure the radiator VISUALLY and add to the heat up stream of the radiator / A/C core.

I have used it the longest and with the mod to the grill and Tstat ( 180 degree stat core - not holes in a stocker), in the summers here in the northern Va area, its cooler on the gauge, below 1/2 scale.

I cant say for this year as the heat will not hit till Saturday and my hood is venting heat like a *****. Testing of the hood is due after I finish checking the 185 pulley out and getting a follow up Dyno in a week or so.

There is a gap all way round the supercooler and the radiator and they are separated by about 3/4th of an inch to allow leveling of the airflow - to avoid dead spots /interference zones.

Enjoy, Woody

 

The supercooler is a full size radiator that is mounted directly in front of the AC Condenser (& engine radiator) thus, possibly, reducing the cooling capability of the condenser when stationary....

 

Im interested in seeing everyones results when the weather gets hot. It was 97 degrees here yesterday and the a/c is definitely not as cold as it used to be. I love the supercooler but if this is what is causing my a/c to be luke warm ill have to remove it.

 

lol wussie

 

What was wrong with the LET cooler?? I run the PTE thermostat and had the cooling fans reprogrammed, that plus the LET cooler has been a really good combo.

 

I think the large surface area of the supercooler makes it superior to LET.

What is PTE and who reprograms the fans?

 

What is the reduction in intercooler fluid temps and IAT's with the supercooler. PTE is the guy who makes the lower degree engine thermostat. LET reprograms the fans but you need to have the car present.

 

Hey Bulldogger a little info please, where did you purchase the PTE thermostat, and what temp. is it set for ? What temp.
was the cooling fans reprogrammed to go on ? This forum is better than Wikipedia.Thanks ILLCYA

 

I think it is 170* I got it through LET, when Eric was around. Look over on the MB forums PTE is the forum name of the guy who builds them. The cooling fans are reprogrammed by a % change in the engine temp. They change the % rate at which they come on. I hope I explained that okay it is not done by an actual temperature number, the fans have a variable speed to them.

what about putting the A/C condenser in front of the supercooler?
that is how it would have been from the factory, right?
the C4 Vettes had 2 radiators and I thought the A/C condenser was in front of the front radiator. The supercooler may not be quite as effective this way, but I bet it would still be better than the regular Heat Exchanger.

just my $.02

I think 3-6 deg, though I have not looked closely at those numbers yet. The IAT's with the supercooler are a consistent 14-20 degrees above ambient when not boosting.

 

Swapped back to the LET heat exchanger and the issue is still there. Im guessing i nocked an a/c hose loose just enough to cause a leak, probably from removing/installing headers 500 times. Will have to take it into the dealer for this. I will eventually put the supercooler back on after fixing a/c.

 

Why would knocking a hose loose only cause warm air in traffic, the A/c system is charged if you knocked a hose loose then you lost the charge and all AC. Hey solving the lean AFR ratio was a 5 minute job

 

Well traffic or no traffic its warmer than it should be. At a stand still its by far the worst though. I have seen cars with small freon leaks have a/c that is cool'ish but not cold, until all the freon runs out then its just blowing warm air. I have checked the compressor and it is comming on. Also, the fan is spinning. I really didnt think i hit a line either but im not sure what else it could be. Im open to suggestions, its most annoying.

 

My AC has been real cold in traffic. Coming back home today from the Dyno tune I got stuck in lovely NY grid lock, 5 miles in 1 hour. Bored I took a picture of the Traffic and my Temp gauge my PTE thermostat and LET cooling fan seem to be working well, maybe this is why my AC blows cold, only problem is my wife always states she's cold. Just can't win.

Bulldogger, i want that PTE thermostat and LET fan!!!! i have never seen either of these parts before!

you're so selfish.... LOL, but seriously, links? phone number? etc.

thanks!

 

Post #11 my friend has the answers

 

There is no "LET fan" part - which is why you haven't seen it

LET/EC can alter the temp the fans kick on by -10*C by using STAR Diagnostic software - as can any shop/mechanic/dealer who has STAR or access to it. They have to know what they're doing, however - there's a whole thread that Jerry posted on MBW with the step-by-step instructions for how to lower the fan activation temp via STAR.

Patrick's (PTE) t-stats are well made, well built units. AFAIK, they're 180*F t-stats for the C32/SLK32/SRT-6. Have one sitting around right now, actually; waiting to go in this spring/summer.
