The ZL1 hood is primarily designed for under hood pressure relief at high speeds to increase downforce and reduce front end lift, the heat extraction is a side benefit.

Makes sense, don't get me wrong I loved what you done. You took on a less is more approach which I like and nothing is overdone. Simplicity as its finest. The wheels are sexy, the hockey stripe and the white liner in the rims sets it off.
I know exactly what Viper hood your referring to, a buddy of mine has it on his, lol.

Technically, heat extraction is better served with the opening further forward from the base of the windshield than you might think. What you want for heat extraction is the vent opening to be in an area of low pressure. Base of windshield is high pressure, exactly what you DON'T want and why it's a good place for things like HVAC fresh air intake (and cowl induction on carbureted cars). Somewhere ahead of that you have a negative pressure region.


Which sort of brings me back to the topic of whether I'd use ZL1 parts on a non-ZL1 Camaro.

If I was after the same functional reason as GM had for their existence in the first place, absolutely. I'd have the benefit of OE engineering and durability testing and a pretty good guarantee of fit.

I would absolutely not do it for appearance.

I do agree with the high pressure region at the base of the windshield, but with the scoop too forward like the ZL1's, you are really doing a lot more for smooth flow path to reduce the pressure under the hood for aerodynamic down force purposes and heat extraction is secondary. The water tray on the ZL1 effectively reduce most of the heat extraction capability anyway. If someone provide a CAD file, I might run my own CFD runs just for fun...

WTF???

A zl1 is a joke. Most SS models with boost or a good n/a build kick their asses.
Why would anyone care about cloning a zl1 is my question.

a zl1 is basically a waste of a supercharger.

Seems to me whether the reason is for heat extraction or downforce/avoidance of lift you still want the vent to exit into low pressure. I may never drive at 150+ mph, but if I ever do I'll want any front lift at least minimized, which comes right back to the same choice of hood.

With all due repect to the OP, modifying camaros has been one of the greatest reasons for the great following camaro has enjoyed. Ease, cost and part interchangabilty has been an intrigal part of the camaro ownership experience since its inception. Heck where do you think the Yenkos came from? They are not worth less today because somebody copied what they did! The factory or dealer prepped cars will always hold their value moreso than a customers modified car. Dropping a big block, that you found in the junkyard, in your unassuming stock straight six was what enthusiasts lived for back in the day. Not to mention the racing that helped improve the product, aftermarket or OEM. To move the camaro from its pedestrian roots to an elitist crowd will only help bring its demise. GM please keep the camaro affordable and mod friendly, this has and always has been its misson. Be happy you have a factory ZL1 and let the rest of us dream that we can build one close to looks and performance on a budget.

And in the end, it's still just a SS ...

Z-28 LIVES!

The 2014 Camaro Z/28 uses the LS7 6.2-liter V8 from the Corvette Z06, rated at 500 hp and 470 lb-ft of torque. The package includes a cooler for the rear differential and carbon-ceramic brakes. The Z/28 is street legal but is designed for racetrack duty.

General Motors engineers worked to take weight out of the Camaro Z/28. It weighs 100 pounds less than the Camaro SS and 300 pounds less than the Camaro ZL1, which runs a supercharged V8. There is no carpet, a one-speaker sound system and thinner glass.

Yep! Exciting news for GM and for the C5 family.
