lol very funny- I know that, but were specific models made with the steel hood versus the aluminum hood, because my hood feels a little heavier than i think it should.

I'm just curious because i might change my hood to aluminum if its steel, or fiberglass, or even carbon fiber- i want something that vents well and lightens up the car, if its worth it

Maybe later in the year of 1987 they realized that steel wasn't cutting it... aluminum was way lighter and more sporty or something. Just a guess. Don't quote me on that.

As far as I can tell, it was pretty much random as far as what the hood was made of. For aftermarket hoods, it depends on what you want to spend. I think there's a group buy or two for aftermarket hoods going on right now, check the GB section. Be warned, they can be very expensive.

carbon fiber hood makes barely any difference in weight.
if u really want weight difference wid carbon fiber, u gotta get carbon fiber fenders, front bumper THEN it will make a difference.
cf hood is more for show than performance.

well, a carbon fiber hood will make a nice difference in comparison to the steel hood 
but if you already have an aluminum one, forget about it. stick with what you got WOOT!

Aluminum hoods have rivets instead of welds and weigh about 20 lbs. If you want an aluminum one go to a scrapyard and find one, don't say it's aluminum though, I got mine for like $50, ridiculously cheap, totally undamaged.

you used to be able to buy aftermarket TII hoods, they were steel.

Seriously, though, even though it doesn't sound like much, that 20 lbs makes a major difference. I can take the aluminum hood off my car without much problem, but it was a bear getting the steel hood of the car I'm parting out.

and maybe you need to get to the gym, because I don't have that much trouble lifting either.

Its not the weight, its the combination of weight and size. Its kinda an akward weight to lift it. Its not that I can't, its just noticable more difficult. It also probably didn't help that it was pretty crunched up, which made it even more akward to lift.

Also size and weight of the car is a nice variable, youd be trying to keep weight on the rear and front as even as possible for autocross. Mainly keeping your steering radius as tight as possible.
Seeing as this is the “Technical” forum lets try to save the AIM Jabber for AIM and use real words instead of trying to figure out everyone’s way of saying you and with.

While carbon fiber is lighter than aluminum, it has to have extra bracing for stiffness that adds to the weight. I think 10 lbs is probably a reasonable figure for weight savings. To me, 10 lbs is a damn small weight savings for how much a CF hood costs. You can easily make that up just by going on a diet.

Rocket: Carbon fiber doesn't HAVE an atomic weight. Pure (elemental) carbon does, but carbon fiber is a polymer. In any case, molecular stucture has such a large bearing on material density that atomic weight is fairly irrelevant for our uses.

The biggest factor for me is that a carbon hood costs 100's of dollars, and an alluminum one costs $50. With carbon being many orders of magnitude more expensive than alluminum, it doesn't really make sense to me.
