Guys, I need a vented hood.

The heat in my engine is becoming rediculous..... It gets so hot now, that If I even try to open the hood, The hood latch that opens the hood burns my hand. Even the little hood proper-upper thing gets hella hot. Why is that. I figure it's becuase of my turbo, Well if thats the case. I need a new hood.

Now I know that Carbon Fiber hood are known to warp from emence turbo heat..... and I have emence heat. So what should I do? I haven't found Any vented hoods made out of the normal hood metal. Can you guys help me out..... Also, would this carbon fiber hood have enough vents, that it would warp?

Haha you know your fast as hell when you need a vented hood to keep things cooooool. Vented hood sounds like a good idea, but I heard the same about carbon fiber hoods. The heat kills them. I would find a shop that will cut some vents in your stock hood, but make it look professional. It would be a one of a kind then, and you can make the vents where you want them. :2cents:

We vented my brother's hood:

I think this mod looks great on the stock hood. Only bad thing I could see about this is that when it rains, it will start to steam from the water hitting the turbo, or heat shield.

yeah, and my turbo, exhaust manifold, and wastegate dont allow me to run a hate shield. LOL, it gets so hot in that damn engine that I actually melted all the blades off my ac fan........... pics tomarrow LOL

This is a beautiful picture....... just look at the smoke being released from the engine bay.


what do you guys think about this hood......

you need a vent the points toward your window so the heat is pulled from the car. It will function better in rain also, you dont want anthing cracking from water being tossed on it while your driveing.

Though the vents cuts were probably the easiest to cut and the moast funational, I personally would go for something a little more....uh...extravagent perhaps. Something similar to the ones below; I think they would give a more pronounces sense of aggressiveness.

Some similar vents, if moulded right in, could look really sweet.









Damn. I feel like a fashion designer :icon16: : "functionality follows form, dah'lin!" :gay:

Hey. Your pic didn't show.... I like styling too. Its the ricer in me :D

Why not use some exhaust wrap. A lot cheaper than a CF hood too. Or both. http://www.prostreetonline.com/buy/dei_exhaust_wrap/

With the heat you're talking about I would expect your alternator needing replacing like every month lol.

If you do get a hood though, you could also get more cold air in there by making some tubing from the bumper to the engine. Like the dryer ducting to the air filter but on the other side of the bumper.

Savior I have that GoodHood, I love it =-)

Do you have any pics of what yours looks like?:naughty:

Shpyder, what rims do you have? And what size?

Shpyder, what rims do you have? And what size?

17"x7.5 5Zigen Copse in hyperblack with 225/45/17s. Wanted to go with thicker rubber, but discovered that I was already too close to the control arm, regardless of how much space the wheel well has.

Those are hyperblack? THey look silver. And to answer the pic question, I will get pics up as soon as I figure out how to put grille in myself. The damn shop guy is my neighbor, and wont take out the steel reinforcement bar for fear of an accident. Any ideas? And if not, it doesnt look that great right now, but Ill give you guys a pic anyway.

I want a pic...... upload asap please..... And I might get that exhaust wrap..... Gotta read more about it

I would think you could cover the vents with a sheet of metal if you do the grayforest mod to your hood, just to keep out extra water when it rains.

Many people just run a CF hood and drop in a Carbonwerks/RRE hood vent front and center. People have logged significant drops in coolant temps and charge air temps while road racing thanks to the adde flow through the radiator and FMIC. This is the reason I meant to do this to the 2g for years. The engine bay is like a big parachute, catching all the air creating a high pressure area, making it difficult to get good air FLOW through the FMIC/radiator.

Luckily the EVO comes vented stock, and coolant temps never get over 183 and the FMIC must be working if I can run 12.7:1 with extra timing at 40 lbs/min and not knock, on pump. I recomend a hood vent for sure!

Water gets in there, but if Mitsu decided it was safe enough to still give a 100k mile warranty, it must be ok. The other downside is that all the heat that is released gets pulled into the HVAC system. If you turn the HVAC knob to the coldest setting but dont run the AC, you still get hot air ;)

well his Mitsubishi isnt an Evo so i would worry about the Rain. i wouldnt want anything under my hood cracking open.

Right. :rolleyes: Make and model will change thermodynamics and reactivity of metal. :rolleyes:

Look into the CarbonTrix vents, like Kevin mentioned, and also try and figure out why you engine bay is so damn hot. Tighten the WG dump tube, manifold studs (to spec!), etc and make sure you don't just have a hot leak going on.

My cock dad took my damn car too work, lol POS. I'll picks up of the hood tomorow, sorry.

What????:eek7::screwy:

Ok I just took a look at those hood vents and they look like something that might work for me. But (I know I'm an Idoit) how do you get the vents functional on a hood? Do you have to do some custom cutting? And If I were to get a Carbonfiber hood and do some cutting, wouldn't it come out all crappy like becuase of how the Carbon Fibers would shed?

Also, If I'm looking into getting a Carbon Fiber hood and putting Carbon Fiber vents on it, what would be the problem with getting just a carbon fiber hood with vents already in the hood?

Sorry, I know the performance stuff, But have no clue about the body mods :D

I have heard a lot of good talk about the VIS CF hoods. It is said that they last through the heat of the turbo unlike some sold on ebay that melt sometimes. I think Shpyders hood is a VIS CF ( not sure) but most VIS hoods come with vents in em.
Weight wise you car will also be lighter with CF hood. Good luck man

I suggest using the heat wrap if a hood/hood vents are out of the question... here's a link to some stuff I have...
http://designengineering.com/products.asp?m=sc&cid=3

I believe they also have turbo wraps...been a while since I have been to that site...

I wouldn't recommend wrapping exhaust in that stuff, much less a manifold, etc. It traps mouisture and causes cracking and other wonderful things.

Cars dirty, but you wanted pics....

Hey, that hood looks pretty good! I could really see that going onto my car hehe.

Why thank you - Its functional too, and the air would be thrown right on top of your intake filter, but its expensive as fuck.

Well, thats good and all for perfromance. But what I really wanted to do was to lets some of the hot ass air from the engine bay out. Do you think this hood would be able to do that. And Lando, thanks for the info on the Wraps. I dont want cracked manifolds or turbos.......

I would think if you wanted to vent hot air your best bet would be to get something like JeckylandHyde is getting for his MR2. Get a hood with the scoop or the vent facing the front window, as air passes over it would create a suction that would suck some air out of the engine bay. Dont quote me on this, but it seems logical enough.

Just a thought, but wouldn't all that cold air coming in from the front push the hot air out undernearth the car, or atleast cool the air down some?

Thats what I was thinking too.... But I'm not sure, And about the hood scoops that face toward the window, I dont like the look of those too much. And i'm not too sure on the whole suction thing. I like to go with proven methods. Has this been proven that it sucks air from the Engine bay?

Damnit I didn't think choosing hoods could be so difficult.

what ever dude, i thougth Kevin was sayin somthing about the Evo being able to do something tricky so the rain wouldnt hurt it, i miss read , plus i dont know muc habout the Evo. :rolleyes:

Are you sure about that? Lots of pros use it. Maybe they take it off a lot though, I don't know. The 2g from the Sport Compact Car's Ultimate Street Car Challenge last year used it. But if you don't want to use the wrap then there's the paint too.

i noticed some kinda packaging near the Intake manifold ? whats that ? or did some one jut set that thier and forget about it ??

Lol, it's a bag of ice from the store. It's to keep it cool as possible for the dyno.

And i'm not too sure on the whole suction thing. I like to go with proven methods. Has this been proven that it sucks air from the Engine bay?

PM JeckylandHyde, he's running a setup similar to it on his MR2.

This is true... but... it is mainly used on new manifolds and turbos... then you also need the sealant on it that keeps the moisture out.
It is proven to keep bay temperatures down drastically but that is in non street racers... I just threw it up as a suggestion.... the wrap they have for the turbo is more like a turbo cozy :) and basically is a soft heat sheild... I think it would be a good aplication for the heat issue...
That's just my :2cents:

Well, as for the scoop bringing in cold air, I dont know, I could be COMPLETELY wrong, but doesnt cold air wanna go down? So it wouldnt push out the hot air. Also, I think something like Shpyder's hood would be better for pulling out the air.

A forwards facing hood scoop is to pull in air (think WRX top mount intercooler), and a rearward facing scoop will let air out. The engine bay is already a relatively high pressure area in my experience, so I'd rather let air out than try to stuff more in.

at least kevin is still here!

the guy tat owns that GSX in the pics with the insane FMIC is the guy that helps tune my car. his name is Roy and he works with RRE.

let the air out...

ok I see.... and damn I love that FMIC

How about something similar to cal induction. I have seen drifters use it, by elevating the back of the hood (by the front window) with washers to let the hot air out?

Thats what I was thinking too.... But I'm not sure, And about the hood And i'm not too sure on the whole suction thing. I like to go with proven mescoops that face toward the window, I dont like the look of those too much. thods. Has this been proven that it sucks air from the Engine bay?

Yes. It's physics.

As you race through the air, the space behind the scoop becomes a vaccuum and it is replaed by sucking the air out of the engine bay.

That is how cowl hoods like this work:
http://www.thirdgenracing.com/projects/4inchcowlhood/cowl%20hood%201.jpg

That is how the MR2 gets it's air out of the engine bay behind the rear window.

And it is why I mounted my "Subaru" scoop backward for my trunk-mounted intercooler:

wait, lol sorry to enter in so late, but a CF hood can deforme from the heat off our turbos??? shit! i wanted to get one OEM style...

The best thing to do regarding melting of CF hood reson, by far, is to take off the factory under-hood heat shield (that cardboard/tin foil thing) and put it on the CF hood. I've been running my Invader CF hood without one though, for more than 4 months now, and absolutely no trouble yet, knock on wood.

As a side note, the vent on the Invader hood really helps dissipate heat out of the engine compartment, amazingly enough ( I had thought it was just a design thing that wouldnt be as efficient in doing what it was made to look to do...if ya follow me, lol). I actually got the hood because I loved the way its design was so aggressive, but it ended up actually being useful also than just dumb eye-candy.

When I had the stock hood, popping the hood after a long and hard run would release a torrent of hot air coming out at you. Now, after the same kind of run, heat coming from the engine is noticably much cooler than compared to before when I ran without a vent; no blast of hot air. I highly recommend that hood for anyone going CF, or just looking to effectively vent.

Awesome post Hyde. Thanks for the info.

I'd rather see imports with vented hoods than ram-air hoods (as Kevin points out, you'd rather let air out of an already high pressure engine compartment than into it, but SmicaA72's hood looks sweet. The links above have another ram air style hood that, IMO, looks really savage also.

I have not had a problem with my OEM style CF hood from VIS. had it for about a year now after the other ones discolored and deformed

For anyone who has any doubt about the power of negative pressure to "pull" as air rushes over the car, there was quite a display tonight at Maple Grove Raceway.

And old school muscle was flying down the track and just beyond the 1/8 his rear window was literally sucked off the car! ... it went sailing through the air and shattered in the middle of the track.

Ok JekylandHyde, I see how it is..... you trying to get my window sucked off...... Thats messed up.

But really, I have no doubt now about what you were saying, as you said, Its just simple physics... But now you got me worried about other things..... like dying.

Sometimes sacrifices need to be made for the good of the DSM

:p

LOL so the OEM style will be fine? like mitsu_eclipse95gst said? as long as i dont get like ebay brand or something? right? i eventualy want a 20g turbo, and hopefully well over 300 HP

I have been running a 20G for over a year now and it's fine! I am fixing to step up to a 60-1 presision turbo....

VIS hoods off E-bay are working pretty good also friend of mine has had one for about a year now no problems. We put his factory heat shield on it. (mine does not have one)

Hey mitsu_eclipse95gst, I noticed you have a carbon fiber interior. Are those any good ? I was looking of changing my interior a little. By the way, any one know any good seats for sale ( either on ebay or other websites) for a reasonable price ? Thanks

It WAS really nice at first!... BUT all the corners are sharp... It kinda faded out alittle (they do not heat treat it or uv protect it) The glue shit that comes with it kinda sux IMO i got some 3M spray and hooked it up though :) I still like it but i kinda wanna go back to stock .. If you like the way my car looks them get it. I think it comes with 27 pieces there is alot more than the pics on my site show!

I might have misunderstood something since i'm a little tired from the trip home, but.. There is a HIGH pressure area right at the windshield, not low pressure. That is why hoods like that camaro one are called cowl induction. A vent there may not do much for extraction. On the curved surface of the hood, where the air speeds along it, you will get a low pressure area. At the windsheild that low pressure deminishes and can become a high pressure area. You'll always see extraction vents at least 6 inches before the windshield, and often in the fenders on the side of the car, where there is no windshield to bollix things up.

Holy crap. Talk about venting...with all those vents, that hood is more a collage of cut-outs than the material it's made on, lol. But I like the way it looks, super aggressive. Except that if it rains, you are S.C.R.E.W.E.D.

I dont know, I think it might have too much going on that it wouldnt look good. I'd have to see it on a car.
