my new hood

[goingganzo]

so what do you think of my new hood? it is cf but i had to return it. it was dammaged in shiping.

[MacLeod]

Looks pretty smooth brother. What car is it going on?

[PolkThug]

I like cowl induction.:)

[MacLeod]

I want one for my Ram. Ive seen a couple around town and they look badasas!

[goingganzo]

2001 olds alero payed 800 for it.

[michael_w]

I have a question about cf hoods.... aren't they supposed to be painted the color of your car ? It seems the trend is to leave them / make them to be just cf with a clearcoat.

Anyhoo, nice hood.

[neomagus00]

what's the point in having a cf hood if no one knows it's cf? generally, it's for the cf look, not to knock off 15 to 20 pounds.

what do you think a totally-cf car would look like? everything, side panels, bumpers, everything! (not roof, convertible, or maybe a folding cf hardtop)

Uhhh...in all my experience, it's the ricers who get carbon fiber for "the look" and nothing else. Racers get carbon fiber body parts to helpp drop weight. Lighter cars run faster and run longer because the power to weight ratio improves and the gas mileage increases.


A totally CF car? Well, if you don't paint it, it looks like crap.

[neomagus00]

yeah, the ricer-for-form and racer-for-function bit was what i was trying to get across, but most people aren't racers at that level, where 15 pounds makes a difference :).

so you've actually seen an all-cf car? any idea where i can get a pic, just to see (google image search has failed me...)?

[Jstas]

Here:

Pick one. Every one of those cars has a completely carbon fiber body. They are painted of course because they would look like total crap otherwise.

[goingganzo]

that is y i got mine blue cf to match the car. i could have gotten a fiberglass hood for about 100 less but it would have cost me that to get it painted so i went colored cf. i am not a ricer or a racer.

cool cars... perhaps they're painted so that sponsors' logos are more visible?

note that i'm not doubting you, i just have an interest in seeing what that weave pattern would look like over a whole car... and i don't have my image editing suite with me... :)

I belive that would be a McLauren F1 and it sure doesn't look like crap... although it is painted :D (btw its possible it is fiberglass not carbon fiber but meh..)

[max3]

I'm not sure but aren't Corvettes made completly out of carbon fiber or fiberglass?

[PolkThug]

fiberglass.

[JDMCivicB16B]

forget a fiberglass corvette..!

take a Civic HB completely cf, sprung weight 1500lbs and pushing 305whp ...what would happen? hahaha

[goingganzo]

here is a pic of the hood installed.

it'd still be a civic...

ganzo - is there anything sticking up into that protrusion? or is it looks only?

[spwuinmk67]

it's a cowl induction hood, its supposed to let more air get into the engine. I'm not too big of a fan of them, I prefer ram air hoods.

Lots of wheel spin and torque steer and probably broken half-shafts.

Corvettes come with 400 horses stock.

Why are you comparing the economy Civic (kinda redundant there) with a Corvette anyway? Completely different leagues. If you want Corvette level of performance, just buy a Corvette. You'll spend just as much putting a Civic at that level anyway and it won't perform half as well as the Corvette.



Oh an cowl induction can do more than ram air. If the cowl induction is functional then, it is sucking that cold, high-pressure air from right infront of the windshield. That means it's very dense air and as we all know, the more air running through an engine, the more power you will make. Ram-air will give you a similar effect but it only works at speed and in heavy traffic, it can actually be sucking down hotter air than what is in the engine compartment.

Another benefit to cowl induction, if it isn't being used for engine air intake, is heat dissapation. Having the sheltered hole at the top of teh hood not only less out the high pressure air under the hood that gets trapped there while drive but it also provides a vent to let hot air out. I have seen cowl induction hoods make drastic drops in temperature under the hood.

[neomagus00]

that makes perfect sense (and i know from my current car that ram induction is bad in stop-and-go, especially when combined with intercooler heatsoak)... how exactly does the cowl induction hood pull the air away from the hood? just a large air intake positioned appropriately, or is it more exciting than that?

[Jstas]

If the cowl induction is going to be fuinctional then it needs an intake pan that usually sits under the carb or throttle body. That pan closes off the hood bulge from the under-hood air and seperates the intake system inlet fom the rest of the engine. When the hood closes, thise creates an air duct for the cold air to be sucked into the engine from that high-pressure area infront of the windsheild.

Some newer hoods for modern EFI systems have ducting that runs all the way down to where the stock air box is located to keep the stock plumbing with little fanfare and modification.

A non-functional cowl induction hood would not have the pan or ducting as mentioned above and would have a large open space into teh engine compartment. Because that pan isn't there to close off the duct, the hole for teh cowl induction molded into the hood acts as a large engine compartment vent. It lets high-pressure air and heat escape. It helps keep the nose of the car from "floating" at speed and helps dissapate engine heat. The nose can "float" because all of the air rushing in through the radiator and under the front-end, it builds up and can actually start to lift the front of teh car up. The same effect happens when you are holding your hand out the window and the wind keeps blowing it around.

[neomagus00]

that's quite interesting, thanks for the info

[exalted512]

i can agree with that, try going 120 in a truck with 33s...front end lifts up quite a bit

[audiobliss]

Ganzo - Looks sweet! The hood and wheels work together to make it look real nice! Have you done anything performance wise to the car?


Jstas - Thanks for the info on cowl induction. I probably would have guessed that ram air would be more effective. Thanks for clearing that up.


Neo - What kind of car do you have that you have ram air, a turbo, and an intercooler?

Haha...my speedo only goes to 85!! lol But doing 120 in a truck on 33s (with you! :eek: ) sounds scary! lol

[neomagus00]

i have a 2000 Saab 9-3 Convertible... stock intercooler and turbo (for now), and i'm in the process of glassing a ram air intake... the mods are happening slowly but surely...

[audiobliss]

Sounds like fun! Glassing a ram air intake...interesting...will hafta see that!! So you're planning on replacing the turbo and intercooler? Sweet...

[PoweredByDodge]

macleod - forget the cf hood for the ram.

three words - SRT-10 Viper Hood.

cost is 600 bucks plain metal - paint the bitch for another 250... that's 900 with freight and you've got the sweetest looking hood you'll ever own.

another nice option - keystone restyling fiberglass functional air ram hoods... oooh they're pretty.

i bought the hemi hood scoop for my truck and it was SUPPOSED to be made functional but i never got around to it.

i was going to cut a hole in the hood, replace the front screen on the scoop, and then build a tray to hold a flat fliter and slam right into the throttle body.

too much damn work. i decided not to - and now i'm glad...

first attempt to paint the hood was a bad one - the paint job was PERFECT but the prep was wrong. i didn't know i had to remove the grey "pre-coat" from the factory, so i ended up with paint that literally peeled off like dead skin after a month.

so i had to rip all that **** off, and when i got to the metal, i had some rust - treated it with phosphorus solution and then just got so aggravated that i cleaned it - used an etching primer, and did a half hour quicker-doodle paint job with spray can's (auto paint of course, not krylon for god sake). now i got little specs from dust here and there, and a whole mess of "in the metal" scratches and ****. i honestly don't give a damn at this point - if i had to do it over, i would have just gotten a whole hood instead of the damn scoop . the mating surfaces are not properly set so i had to re-arc the whole piece in some places. an utter nightmare. 200 for a scoop + 60 for a premium quality set of paints to use with an air gun - then another 35 for ****ty paint to redo it... 15 for phosphorus solution - countless hours of my time... i'd rather have shelled out 5 bills and got a keystone hemi-replica hood (looks the same as the stock hood with the stock hood scoop - which is what i got - but it is made of fiberglass and is all one piece - and the hole is already there, but they give you a little plate with a rubber gasket you can screw on the bottom if you dont want to bother using the air intake **** -- they also sell an air intake tray / system thingy that hooks right in for another 200 bucks... for the sake of simplicity - i think its not a bad deal.

ROFL

Sorry, but that's just hilarious. As is the rest of your story. LOL

[goingganzo]

here is a new pic i just lowered it. next is to get some componets for the interor.

[audiobliss]

Overall, it looks real nice. Looks a little too low in the back for my tastes, but it sure does look like one nice Alero! They're beautiful cars!

[HiPerf360]

The CF hoods that the ricers are running might as well be fiberglass, they are thick, and have way to much bracing on them.

The race car CF panels are EXTREEMLY expensive:

CF door for CTS-V $4500.00 ea.
CF hood and decklid $2500.00ea
I dont remember the roof and fender prices but they are through the roof as well.

Most of this price difference is due to low volume but they are totaly different.

[audiobliss]

:eek: Those are some stout prices! But, I had never thought about the thickness and bracing being counterproductive.

[neomagus00]

that's kinda the point of CF... as little material as possible to do the job, and that **** is strong... but somehow, those prices seem really high... i think that if you hire a fabricator to make a mold of your hood and do a custom CF hood from that, it'd be cheaper... though i can't say that for sure...

[HiPerf360]

That was a fabricator....

Crawford Composites

[drew spelts]

The #1 thing I would change at this point for looks is the front bumper. It sticks out way to far. You need something with a less pointy appearance maby a little more stout or flush if you get what I am saying.

[neomagus00]

not necessarily just for looks, either... you get a proper air dam, get some actual downforce... :eek::D

[2002tahoe]

just a question, why would you upgrade an alero.

[audiobliss]

just a question, why would you upgrade an alero.
Just a question...why would you dig up an old thread? But then again, this forum is so infrequently used, I guess it was still probably on top.

And, because the Alero looks great.

[2002tahoe]

i guess its personal taste, but everyone else is just fricken stupid. theres no car thats made primarily out of carbon fiber. they are made out of fiberglass!! and to get a smooth enough carbon fiber for a car body would severely reduce the weight advantage. just to let you know

Some F1 cars started using carbon fiber chassis back in the '80's. Carbon fiber hoods are a great way to reduce weight for competitive racing.

[2002tahoe]

except i don't think that the olds is going to be racing anytime soon competitively and with F1's or street racing. unless he secretly has a ZZ572 underneath that hood.

[goingganzo]

well this is now my winter car once my new car comes in i have on order a saturn sky redline.

[zingo]

Note quiet my cup of tea, but here are some cars with unpainted carbon fiber body panels.

[PolkThug]

This is my favorite CF body:

[ilikesound]

that's a pretty nastyass looking car.

[zingo]

I finally replaced my hood with an ABS one, and I have been liking it. It has some flex, but doesn't get warm at all which is really nice over a diesel engine.

[Face]

Just a couple FYI's.

The current ZO6 is CF and fiberglass(actually plastic).

And cowl hoods only help cool the engine compartment on anything made after 1980. They only worked well on old muscle cars due to the poor aerodynamics of the windshield area.
