WEAPON-X: Vented Hood Cowl – Carbon Fiber [C7 Corvette ZR1] WEAPON-X Motorsports

The C7 ZR1’s engine makes some massive power; however, with this power comes a lot of heat too!  Have you ever noticed how hot the carbon cowl is?  In our testing, the lid of the supercharger would be approximately 145° upon shutting the engine off, and within 2 hours, it was 165° due to the heat being trapped under the insulated carbon fiber hood cowl and the conduction that occurs from the hot engine below it as it soaks up to the lid.  This is extremely important because the intercooler bricks are located in the lid of the supercharger, so all of that heat gets soaked right into them and robs the overall cooling potential that could be achieved as the hot charge air passes through them. 

We chose to address this in two ways to combat the heat soaking through conduction (transferred through metal on metal contact from the hot engine below) and convection (transferred through the air as the molecules move):
1.  Cowl Ventilation – We integrated the C7 Stingray’s hood vent into the carbon fiber cowl to allow air to extract from the top of the engine, which will help keep the engine and supercharger cooler as well with convection.
2.  Thermal Lid Spacer (optional, black in color) – We made additional clearance for our thermal barrier, made from a patented material that reduced the lid temperature by over 30°!

While the manufacturer is working diligently on the lead times, manpower issues have production around about 20 weeks.

*NOTES*
WXM aero are custom/made to order parts. If you order during a sale period, the lead time can increase slightly depending on order volume. All aero parts are custom order and can not be cancelled as per our cancellation policy once the order is confirmed and accepted.

Carbon fiber requires a lot of hand work and while we strive to have our parts perfect, just like the OEM carbon fiber, there can be slight imperfections.  Rest assured, these parts are as good as OEM, if not better.
