Its not just about the weight, that can be made up elseware. The functional venting will be important to some.

I would like to know the difference in weight between stock and fiberglass.

Yeah, Wtf??:shrug:

If it were legit, I wouldn't consider the GT350 replica.

Am I the only one who thinks the fake scoop is ricey?
I view it the same way I view those glue on pep boys hood scoops. I'm convinced that the only reason I haven't seen a roush scoop glued on a PT cruiser yet is that it costs more than $20.

My findings are from a guy who has run multiple types of vented CF hoods on race M3's. Could be me, I don't remember... Most cars with cheap, non researched vents end up losing downforce, and end up adding underhood pressure, instead of properly venting and hurt performance. A friends race team saw it with the roush front end/ hood combo on the 2010-14 race car they ran. I had problems with my BMW hoods till I got some $$$ ducting from behind my radiator done up in CF. So don't trust it till you see some real numbers, or some wind tunnel data. Until then, $1700 for some terribly minute gains (less than a mph on a straight) is just idiotic. And probably less than a degree of cooling at anything less than 140 mph.

Have you even looked into Tiger Racing? They have a great rep in the HPDE Mustang world. That hood was wind tunnel tested on the S197 although I will admit that I don't know if it was tested on the s550.

Edit: For your (and others) viewing pleasure. Boss 302s wind tunnel test with Tiger Racing hood. Maybe Ford just wanted it to look cool though.

Ford wind tunnel tested the stock S550 aluminum hood as well, and moved the heat extractors to where they were from the s197.

I bet its a great hood, but to me its not worth $1700 to save maybe 1lb over stock aluminum. Want to save that one lb, cut/press vents in your stocker.

Yeah, gonna just get some heat extractors then

Now what options are there besides Roush
Anything made for a GT is going to need the hood stamped like the stock GT hood. You could do something custom, or buy a GT hood and the vents to go along with it.

You should post back if you pick one up and what the cost was. The list price is pretty high, but I'm sure you could pick up a better deal through a good dealer.

Received a pair of Roush Air Extractors yesterday.
Not really excited about the idea of drilling my hood though.

? Your name says that you have a V8. This is an ecoboost thread. I'm pretty sure yours will just drop in where the stock ones go. If you don't have a GT it will require a lot more than just drilling to get them in
