The only issue I have with the ECS kit is the lack of radiator and A/C flow for my Z51 car.

Could very well be installation error from the previous texas shop (because some things were cut in a way that will make a sane person say "W T F?")

Once I cut out the bumper support a bit to allow air flow, the car stays cool in 90 degree temps and A/C on full blast.

The A&A kit does the intercooler placement differently, thus I haven't heard much about the cooling issues with their setup.

All centri kits have the same issue. I like the ECS intercooler setup for cooling FAR FAR more than the other 2 options. It doesn't block the whole radiator, just part of it unlike some other options that block the whole front opening.

Then they all suck until you open that bumper support. 90 degree day, stop and go traffic, A/C on full and a black car, even on e85 is rather unbearable when the coolant temps hit 240 and the A/C is ineffective, thus requiring you to stop the A/C, open the windows so the motor cools off to 230.

Now, with the fix, I've seen 205 in the same situation.

This is the primary reason I went A&A on my GS. Their intercooler design is not obstructed by the bumper support and they include the Dewitts upgrade on the dry sump GS/Z06. They also include block off plates/brackets to keep the majority of the air flowing through the intercooler & cooling system. I never had any issues with cooling when running just the A&A kit without meth injection. Yes, the temps would go up if doing repeated runs, but they would drop back down very quickly after letting off and just cruising. I could typically do 4-5 WOT highway runs back to back before reaching a level where I felt I needed to let the car cool off for a few minutes. My normal coolant temps were within 10 degrees of stock (pre-blower) levels, and even sitting in stop and go traffic my AC never shut down and I never exceeded 230 degrees on the coolant (FYI I would see up to 230 pre-blower sitting in traffic on a hot (100+) day). Adding meth (or meth/water) injection will help pull additional heat out of the intake air, which will alleviate heat transfer to the coolant & oil, which is one reason why I think you'll find ECS and their installers really recommend it for their builds.

It isn't about the bumper support, it is just blocking airflow to the radiator. Radiator upgrade and fans fix any cooling issues.

Was driving around yesterday in 117-118F weather, and car never saw over 217 with AC blasting ice cold, in stop/go city driving.

Unreal, are you still on an aluminum shortblock or an iron block? I'm wondering if the iron block not shedding as much heat is some people's issues. Even in 98 degree heat with a heat index of 112, my car never missed a beat. It's a cut down Dewitt radiator (don't judge me haha), trimmed 05 fan that's sealed to the radiator, minor ducting, front bumper opening trimmed, and a vented hood but a Procharger race IC. Between an iron block and lack of street tuning, it could put some people's cooling system over the edge.

I have the tall dewitts and dual fans at 90% and that didn't solve a thing.

it's a huge _FACT_ that cutting the bumper support in fact dropped temps 40 degrees all around. Hell the tunnel heat 20 degrees cooler as noted by my thermo gun.

Yes, I have the proper air dam under the car as well.

Iron block.

Jason, you would have had the same issue with any of the centri kits. They all suck when it comes to radiator cooling. And if by dual fans you did the dewitts/spal dual fans, those are a big downgrade from factory. So that explains part of it. They barely move any air.

JasonCzerak

which is my point. However, if the A&A intercooler is moved forward a few inches from where ECS puts theirs, i'd imagine the A&A would be better assuming the car as the factory air dam under it that's supposed to force air up from under the car. If that part is removed then there's not hope regardless of supercharger or not.

Unreal

Its a trade off. They move it farther forward, but now block the whole front opening. ECS only blocks ~60% so it allows fresh air to hit the radiator and air filter. Its basically a wash when it comes to cooling. I've ran both, and noticed zero difference in cooling between the two.

Cut it up!

Looks to be still for sale. Did you end up taking a look at it?
