I went ahead and cut it myself. The C5 and C6 both have a really big issue with parachuting. The C5 is really bad about it. This bumper will be exclusively for accommodating the chassis mount wing on track days, so I figured it would be a good bumper to experiment with. A lot of people cut the bottom half of their bumpers off on C5's, but I really don't want to do that, so I decided to go this route instead. I'm also going to open up the center and put a trans cooler back there, but I won't cut that section until I do the cooler.
Hey idk if you added the oil cooler yet, or what kind of intake you have, but if just leave your license plate hole open the air should flow under the crash bar hit the angle of the shroud and go right into your air intake. Thats what I’m going to try with mine. Great video btw
This opens the front end up A LOT for air which is great for cooling but horrible for drag. I think it's a cool idea, but it depends on your use case. Spec C5 block offs are worth a good bit of speed which shows even the holes themselves aren't helpful stock.
This is actually significantly better for aerodynamics than the factory design. From the factory, the air just get trapped inside the bumper and swirls about, creating massive drag and lift on the nose. Yes, the spec block off plates are great if you want a full blown bottom breathing race car, but personally, these look and function 10000000x better for a hybrid street/track car.
@@ChaseFarrow wouldn't this also allow more faster air into the engine bay allowing air to shoot out of the hood vents faster increasing downforce too? That in itself would cause more drag however I'm willing to bet drag coefficient is similar to factory, which on these cars is already pretty crazy, and the front downforce that I imagine you gained is worth a bit more drag in my opinion.
While it is true that they're meant to withstand higher temps, an engine running at 190°F is more efficient than one running at 220°F. The other thing is that, the cooler the average overall operating temp is, the easier it is to keep the temps from running away under heavy load.
That's a really good question. So the hood vent isn't there because enough air wasn't coming in. It's there because air needed to get out. C5s are notorious for trapping hot air inside the engine bay, creating lift on the front end at higher speeds. The hood vent helps evacuate that hot air, improving both cooling and stability.
I'm actually working on an update video right now! I had to finish up the rest of the car, and then we had a couple of weeks of "Not-Z06-friendly-weather." It'll be a part of my next video on the brakes!
Your best bet would be to shoot him a message on IG! His handle is @livin_twice. Just tell him Chase sent you and he'll get you sorted! If you don't have IG, Facebook would be the other option. His name there is Sean James. He's also currently working on the website for his business, (Highway Game), so that will be the best place to order from soon!
That's not a bad number. There are a few factors that are going to influence coolant temps on these cars, though. I live in Texas where we routinely see 2+ straight months of 100*F ambient temperatures. Just driving in traffic can be pretty tough on temps, let alone track days. Whether or not the car is modded, (and to what degree), is another pretty significant factor. As you start adding more power, you'll start seeing temperature increases as well. Since converting to a front breather set-up, the highest I've seen was 215*F, and that was after several laps on the road course at LS Fest. If I get on it on the street, I see around 195*F, and that's with a completely stock cooling system.
@@ChaseFarrow I had my running temperature lowered in my tune. And I also have a remote fan switch I used before that. I had alot of issues of overheating wile at the track having to wait for cool downs.
@Corvette_pilot Yeah, these really struggle with that sometimes. This definitely won't be the end of my cooling modifications, but I wanted to work out the airflow aspect before doing the rest.
@@ChaseFarrow i have an 03 Z06 and its overheating on the road course. Those ducts are a great idea. One other thing to think about is your lower radiator hose. If you squeeze the hose, you can squeeze it closed. Im wondering if at full throttle the hose is sucking flat and closing off any coolant flow. Years ago hoses used to come with a spring inside to keep this from happening. I think the springs are available aftermarket. Im gonna put one in or use a piece of aluminum pipe. Also don't forget a good set of steam pipes that mount under the intake manifold. Also, getting rid of your thermostat and using moroso flow restrictors has worked for me in the past. You just don't know under race conditions if the t stat is working correctly. Whats up with those holes in your rear bumper?
That's another part that doesn't have a link/website. You'd have to reach out to @corvette_designer on IG. HOWEVER, unless you're going boosted, it's not going to be a beneficial mod.
For your back bumper are you seeing that much wind getting stuck or more you bought it for the wing and it came like that.

It blows my mind that they didn't do something like this from factory.
please do a follow up on this and tell us a longer term results.
This is dope. I plan on grabbing these at some point. Are you getting his diffuser as well?
That's the plan!

It would have been nice to have these direct airflow up into the engine bay and intake

More info that is needed, I've been working on this, Thanks!
Glad I can help!
Aluminum LS engines are designed to run at 220f plus. Look where the fans come on in a stock program.
While it is true that they're meant to withstand higher temps, an engine running at 190°F is more efficient than one running at 220°F.
The other thing is that, the cooler the average overall operating temp is, the easier it is to keep the temps from running away under heavy load.
sweet, its about time someone made this. ive seen a proto on the forums a while back. where did you get the edge trim?
I just picked it up at AutoZone
Do you need a hood vent now that more air is coming into the engine bay?
That's a really good question. So the hood vent isn't there because enough air wasn't coming in. It's there because air needed to get out.
C5s are notorious for trapping hot air inside the engine bay, creating lift on the front end at higher speeds. The hood vent helps evacuate that hot air, improving both cooling and stability.
Is that the C7 Carbon front plate filler vent? Ur cars badass btw, beautiful!
Thanks, man! It's actually from Corvette Designer in Poland!

That’s just about how a Vararam breather system is .
It's close. The Vararam is for intake, however, where this is for cooling.
