The radiator is laid down. The undertray helps tremendously with downforce as it is tunneled. Temps at 90 degrees and it runs 240 oil and 230 water and it is driven hard. My other car is a C7 ZO6 and it runs around 290 oil on a hard run (2017 manual).

Mick,
How much fab work is involved to lay the radiator forward like that? What level of improvement in cooling do you see from that change?
The fab includes making new brackets for the radiator. Not a big deal. We ran the intake through the frame so it is a little more work. I cant tell you about how much better it cools because I bought the car used and had the work done. But, I can tell you it was actually about 95 with high humidity and that was the highest temps I recorded. The laid down radiator actually causes front end down force as well due to it's angle. This is running water wetter and water. It is so impressive. Need anymore pics or info let me know. The problem with the C5, as I am sure you know, is that it is a bottom feeder for air. This totally transforms it to a front breather and it is happier for it.
Hi all - Have any of you guys actually bought anything from ACP recently?
I called them and spoke with a lady there who wasn't too clear on what parts were what. Followed up with two emails, neither of which have been answered after 2 weeks???
Yeah, she is their phone operator and she knows very little about the business. I always ask for Kerry and if he is not there, he usually calls me back if he is not out racing somewhere. Although he did call me back while he was at the racetrack.
With the ACP stuff you need to use there bumper, undertray and splitter. With the Blackdog bumper it allows you to mount any flat panel undertray/splitter assembly that you want. Homemade Alumalite, or some other purchased piece.
It seems like all of these guys are a little hard to deal with from time to time but if you are patient you will get your parts - it's just not going to be as quick as we are used to for other parts.
The ACP bumper will accept another splitter or undertray. I use a alumacore undertray with my set up. Ecklers sells splitters that will work with the ACP bumpers. None of these products from any of these companies are just bolt it up and go, a little fab work is needed.
I've installed 2 ACP front ends and they both needed a lot of work to get the splitter to come out properly - granted that was 10 years ago and they were my first installs but it was enough to make me search for another option. The ACP set-up is 3 pieces - you have the bumper, the splitter which mounts to the bumper and the undertray that fits below the splitter - in my opinion it makes the installation more complicated because the splitter and undertray are traditionally the same piece. But ACP separates them - that sort of forces you to shape your undertray to fit under there splitter. You don't really have the freedom to design your own (unless it fits their splitter) or use a piece from AJ Hartman etc.
One thing that really helps both the performance and the ease of installation is by making the undertray angle adjustable, this way if you install everything and the splitter angle isn't where you thought it was going to be you can change it. My first couple installs were not put together with adjustability in mind. To me the ACP set-up makes it more difficult to make the undertray truly adjustable.
Blackdogs bumper extends down far enough so you can use any flat splitter/undertray that you want - to me it's a cleaner and easier piece to work with and I from my experience it fits much better as well.
I have also just installed an undertray below the stock bumper and added a sheet aluminum air dam to bridge the gap between the undertray and bumper cover (similar to the G-speed lightweight C5 car).
Any time you add a functional splitter/undertray to a C5 it's going to take custom fab work to get it done, I tweak things every-time I do one after doing 8 different installs my experience is that the ACP is the most difficult to install, followed by using a stock bumper and with the Blackdog being the cleanest and easiest (but probably the most expensive as well).

I have been using the Blackdog C6Z Front Nose & Splitter for over 2 years. It is carbon fiber and it fits well. The bottom splitter is a carbon fiber honeycomb structure and it is not flat. It has raised sections on each side in front of the tires to provide down force. This splitter goes back to about 1 inch in front of the engine cradle.
Blackdog installed this for me and it has an aluminum frame on the inside, which provides the structure/connection to the front bumper and engine cradle. The radiator also sits on top of this frame. I have included a couple of pictures.
This was developed by Blackdog a few years ago when they were racing C6Z's in the World Challenge Racing Series. If you have questions send an email to regis@blackdogspeedshop.com
Glowing Rotors....is that the "extended" front bumper or the OEM style? I tried asking about the difference, but they didn't respond. I assume they took some artistic liberty with their design, knowing no one at SCCA Pro back then would know the difference.

That would be the standard. My car had the extended Black Dog bumper/splitter.... It wasn't very pretty, but was probably functional.
David, My bumper/splitter is the Standard, which is the same size as OEM. Fleming23 looks to have the extended one, which provides more down force. Glowing Rotors

Front breathing bumper, splitter, fender supplier?
