CF vs FG - what are the disadvantages of FiberGlass?
Hello,
I am thinking of getting a vented hood to help cooling (not that there is anything wrong) and I was wondering what to choose cheaper Fiberglass or Carbon Fiber.
I would like to know whether it is one these "you get what you paid for" with FiberGlass as it seems to be really inexpensive compared to CF.
Thanks,
Sorry for my laziness if there are plenty of threads on it already...

Depends what you plan to do with the car. If your going to track it and weight is of value, of course you would benefit from carbon fiber. Or if your going for a show car look or not having the hood painted, it would give it that aggressive look. However, if your just using it as a daily necessity to vent heat or might paint over it to match the car, fiberglass is just fine. If anything your just getting the "look" of it from my opinion.

why don't you do a cooling mod that would make a bigger difference, like upgraded oil coolers? The stock hood is plenty light (aluminum remember?), and half the aftermarket hoods out there are flimsy pieces of **** that don't last (especially fiberglass). You may also have to deal with the bullshit of hoodpins.
If your goal is better cooling there are so many better ways to spend your money.

There's almost ZERO parts on the market that take advantage of the extra strength of carbon fiber (and thus extra weight savings). Most just have 2 products, a fiberglass one, and a fiberglass one w/ a cosmetic carbon layer.

I have already spent time and money on the water cooling system so far (Pettit AST, rad silicon hoses, Koyo rad, FC thermoswitch) and I am at the point where it 's either oil cooling system or vented hood (engine's 9000 miles). One thing though, is I don't have a garage, although I found ways to do everything myself so far, upgrading the single oil cooler on my Touring by a Mocal or Setrab for instance would a bit complicated for me and my limited garage availability issue). I will AutoX and track it with limited usage and "spirited driving" street most of the time (not my daily driver either). I thought that vented hood just for cooling efficiency would be a good idea. I realize oil cooling efficiency would be more beneficial but at one point hot air escaping cramped engine bay would be good too (ideally both I know, well eventually, don't know ratio).

And how about in terms of reliability and life duration (I don't know if one would go bad earlier, or whatever disadvantage of either of those, apart from weight saving)?

Lets say the carbon is 4 lbs lighter, do you really think it going to improve any aspect of your car? The only impact it will have is on your bank account...... Dont get me wrong, I like the carbon fiber look, but especially in a street car is possesses no befits whatsoever. BTW Loyoto Machida ftmfw.

AI systems are possibly the biggest cooling upgrade around because they keep the temperatures down at the core. Especially if you're going to the track.

Dry Carbon refers to Carbon infusion and Pre-Preg constructions.
Wet Carbon is all the rest.
The reason cosmetic carbon is used is $$$. Let's say a hood in CF today is 750$, well a "proper" CF Hood would easily be 1,500$ just because you are using a material that is 10 times more expensive also Epoxy resin is also much more expensive than Poly or Vinyl Esthers.

90% of the FG hoods people bring into my shop to have painted fit like ******. Although most people seem to be perfectly happy with, and actually RECOMMEND them afterwards. Don't know why, maybe I just have high standards?
CF will *usually* fit better out of the box because the company selling it knows you're just going to bolt it on and go. A FG one has to be painted so they leave it to the body shop to fix their SHODDY work.
That's my findings anyways.
OH. And no matter what hood you buy, if its lighter then stock, I'd be amazed. If you're concerned about weight at all unbolt the stock hood and feel it. **** weighs nothing.
