i have a carbon fiber on my vert, and to be honest the vert hood feels just as lite as the cf. i bought mine because i love the look , but mainly for the free air flow in the engine bay. in the summer here ,it hits like 105 to 110. so i need everything i can get to keep that baby cool

I have a steel hood right now but rather than spendign $700+ shipping I got a Al hood for $75 off a good friend. Even if I paid the normal $150 they go for its still alot more reasonable/sensable than CF.

That is because the alum NA hood is ~22Lbs and the TII one is ~25Lbs because of its extra duct- not 30Lbs as stated in this thread.
I think it is AWR that makes the 7Lb CF race hood skin for the FC. It will weigh even less once you cut it for the pop up headlight lids

man ...f..k what everybody else thinks about the carbon fiber hood been ricey ..remember its what you like and can afford not what he or she thinks of now because..come tomorrow you will have a carbon hood and they will still be stuck on ...duh when is my engine gonna run duh
if you got the cash and want the look and weight savings do it
steel- heavy
aluminum-light
carbon/fiberglass-very light

None of us are saying that a carbon hood is a bad thing. Many of us are saying that unpainted carbon hoods like bad. And I think that most of us agree that an FRP hood would be the way to go because you still get the weight savings, but at a fraction of the cost of a CF hood.

a Black or CF hood on a red/white/etc car looks ricey because all the tards do it to their rearend accident cars.
My car's black so it naturally blends in(at certain angles). I think it's a somewhat subtle body mod for looks. It's no GP sport kitr or RE Ameiya rear wing but it still makes people check it out.
I also did a TII swap and did not have a TII hood. Do you know how hard it is to find a TII hood in AZ?
CF also does not have to be painted(optional). The FC3S hood is a FG underframe and the main top part is CF.
Speedmachine/Fiberimages hood is top notch stuff. I've had it for 2 years on my daily driven TII in hot AZ sun. No fading/yellowing or hood latch problems.
Close up
From far away.
Also for the Thieving part. At least in AZ us RX7 guys are tight knit. Trying to sell a CF Rx7 TII hood will be damn hard especially since they have serial numbers on them.

Here are some other pics.
Also. If you didn't notice in ALL of those pics the scoop/intake on the hood is MOLDED in. NO TII stock hood is like that. They are seperate pieces.

while true i dont know much about carbon,(i have done very little work with it) but i do know a bit about its sister fiberglass, in fact ive been helping my dad and his friends in building 3 planes out if it, 2 rotary powered at that, this project is partaly what lead me to own a Rx-7. (full sized 4 seater MKIV canards.) All work is done in a hanger in howell Michigan, im fairly shure they wouldn't mind anyone coming out and taking a look and helping out. (work is done on Saturdays or sundays)
its made of ~99.99% fiberglass, epoxy, foam, micro glass beads, and a fiberglass filler. rest is wood or metal
(you can see the nose of the 2nd plane in this picture)
The power plant, this engine was thrown out (due to unusable housings) in favor for a renisis crate engine (just came in last month) the other plane is using a lycoming flat 6 engine and my dads will use a renisis too most likely.
