As many of you are aware, we're working on a cooling package for the C7 Z06 overheating problems, and we're having some great results with our prototype package. The time has come to start production planning, and we'd like the community's help in figuring out how seriously to pursue this.

We're still figuring out the final configurations, but this package will address the following problems with the Z06:

• Supercharger Coolant Overheat
• Engine Coolant Overheat
• Transmission Fluid Overheat
• Engine Oil Overheat

At this point, we need to figure out how much more work to put into the production kit. We can make the car never, ever overheat without cutting holes in the bumper, but it will be much more expensive than the current prototype pictured above. Community interest will help us decide which option to pursue.

This survey asks the following questions:

• What would you be willing to pay?
• How much is it worth to you, to not cut holes in the bumper?

We'd also like to hear any other thoughts you have on bringing these parts to market. If you supply your CF.com username on the survey, we will provide a discount code for this kit when it reaches the market. All answers will be kept confidential, and will not be published.

Thanks in advance for your input.

Done. Forgot to comment that I'd rather not touch oil lines. I'm fine with cutting the bumper though.

Excellent work so far guys.

Some thoughts on bringing it to market and the questions in the survey.

A 'non-cutting' fascia option would be excellent but personally I would find it hard to justify the cost if it's more expensive than simply buying a new fascia with painting it. However, there is some intrinsic value to simplicity of installation without the extra steps of painting.

Do you think this 'non-cutting' option would be ready soon or is significant R&D still required? It seemed the airflow through the OEM grill was part of the issue. Simply not enough area. I'd be very curious to hear how you'd keep the stock opening and make this all work equally well to the 'cutting' approach.

GSpeed

There's some R&D required still. Basically, there are more exotic heat exchangers we can draw on from other industries, but it would add a lot of cost to the system. This survey will help us determine if those exotic options would be worth our time.

One Curve at a time

Survey answered.

For street usage, maybe they could re-use the bumper cut parts so they can cover the air dams?... Something with clips that wouldn't look too Nascar alike..

GSpeed

I'm not sure I fully understand what you're asking. You mean to cover the front-facing intercooler radiators? Assuming for cold weather, that shouldn't be a concern. The ECU automatically disables the intercooler pump when temperatures are too low, and our system won't change that.

I would prefer to cut the bumper if it can be made to look good. The GT3RS has big openings up front and they look great. I think it just needs to be well executed. Right now I prefer the look without the trim pieces than with - but it still needs something. I do think a grill of sorts would be good.

Survey answered. I have no problem with buying a new bumper and getting you guys to install what you can. I can take care of the paint or wrap it. I wonder about intermediate steps. i.e what if one just used the Aux radiator and intercooler reservoir (without air), any idea of what the ambient limits would be with that set up? Or just the twin HX front end without the Aux radiator. What is the consensus regarding warranty? I realize with modified cars the warranty is always at risk. I also realize this may be an all or nothing deal to make sense for you guys, but thought I would ask about a phased cooling improvement. Hope you get enough interest to be able to make this available.

GSpeed

All parts we make have a warranty against manufacturer defects. Given the use case of these parts (racing/motorsports) we can't guarantee more than that.

We will certainly try to have a phased options for different use cases. As we get a better understanding of what the production parts look like, we'll be able to provide more information.

Thanks for your input.

Ok...I'll cut the bumper to save some coin. Find a nice black grill to put in those cutouts along with black radiators and it'll look great.

Operations

You guys pretty much already know my thoughts, but I'll officially say "I'm ok with the cut bumper, especially if it's tastefully executed."

GSpeed

Jake was hoping for a curve ball, you know, "hey guys, I don't think I want to cut my bumper....."

Operations

I thought about it

The kit should simply come with a pre-modified (non-painted) front bumper for a more pain free installation without people butchering their cars hoping they do it right. Or make a mold of a properly cut bumper and source an aftermarket vendor who is capable of replicating the bumper to a high enough standard that the C7 community would agree to run.

This way, no one is required to cut their factory bumpers and paint up for any future needs including resale.

Anyway to use the brake cooling ducts to supply air to the HX? Will they supply enough air? We can run a brake cooling duct similar to the one used on the ACR. The duct attaches to the lower control arm. I have a keen interest in a kit since the only reason I have owned my last few Vettes was to track them.

GSpeed

Bumpers from GM are surprisingly cheap. I think we paid about $240 for the one we cut up. That's definitely an option. Might be some delay associated with that option, of course, but we can totally do that.

No, there's just not enough surface area exposed. The cheek coolers add over 150 in² of front-facing surface area. They're not the most aesthetically pleasing solution out there, but there's a fundamentally good reason they work.

Not to mention the crash bar and frame around the brake ducts make packaging in a heat exchanger more difficult than you'd think.
