What cooling systems are you guys running?

Agreed. That little electric fan with no shroud isn't doing much at all to help you out. A properly sized and installed stock fan shroud along with a GM 7-blade fan and new fan clutch should help out tremendously and is probably the cheapest way to go. An electric setup is great too, but might be a bit pricier and you might have to deal with clearance issues, amp draw, sizing, shroud setup, etc. Derale makes a heavy duty flex fan that works nicely also and looks good too, but it's a bit too heavy in my opinion(I tried it).

The setup I use which is rather simple but works great for me is:

fan: GM 18 1/4" seven blade, Classic Industries G8354
shroud: GM NOS, Big Block 69 Camaro, Ebay
clutch: Thermal, 3" depth, big block application, local parts store

Just be sure your belts are fresh and tight because it will put a little extra drag on your water pump pulley, especially at high RPM.

Whatever you decide to go with, good luck!

Single core aluminum radiator with plastic tanks and a 16 inch Hayden fan in the stock shroud. Also have a high volume edelbrock water pump. Can idle all day long in 110 weather.

and Spal fan controller.

195* Robert Shaw high flow thermostat:

And then I stuffed as big as a Earl's Transmission and Oil Coolers (with thermostat) and a Perma Cool P/S Cooler as I could fit.

Here is a pic of everything:




It just barely clears the hood latch and center support brace, and RS doors, that is why they are not centered in the radiator. I could fit way bigger coolers if my car wasn't an RS.

I sure hope all that blockage doesn't cause you slow speed cooling issues Ed.

I hope so too, but cooling the oil with a cooler that size should be worth some serious drop in temp anyways. I also have the radiator support sealed to the radiator so there is no place to go but through the radiator.

Played around with some 1600cfm blower fans. I turned them on after the gauge passed 210. The extra air movement dropped it back a little below 210. I let it idle for 15 minutes and it stayed consistant. The coolant is full and I believe I have the air out of the system. Does it sound like a couple decent puler fans and a shroud will do the trick? Should I be shooting for a lower temp? Are there more things I should be checking?


Thanks

Yea, but don't some people block thier ENTIRE radiator with an AC unit or an intercooler?

I will be running an Autorad radiator along with a Setrab 925 oil cooler.. I predict no cooling issues.

We use the top of the line afco polished radiators and have Mahafee shrouds build a dual fan set up with a shroud that funnels to the fans. He builds beautiful shrouds and they work. BB's with a/c no problem in Texas weather.

You have a different scenario. You are still getting air to every core 3/4 of the way across your radiator. He's blocking 80% of his core leaving he top 20% for unrestricted flow. The only place I can see it having a potential problem is on the race track where you need that flow across your core . I do have a condensor in from of my radiator but the resistance is constant across 95% of the core. I agree, you'll be in great shape. Ed, good luck buddy.

We manufacture a killer system for 1st and 2nd gen Camaros. Not only do we make our radiator 32" wide, but we fit it with dual fans and fabricate an aluminum core support to complete the package. Your overheating issues will be history and you can use the AC too.
