Working hood scoop

[Jeeprider]

Does anybody remember the sweet tones out muscle cars you used to see? With the big blower scoop with the flaps that turned when you throttled the engine? Was wondering if anyone has thought about making one or has made one for their nitro engine? personally i would think it would look wicked, was thinkin bout fabricating one. Would actually be part of the intake system too. Any thought?

Seems like it would be more restrictive than functional.

I made one scoop but on the side on my savage X, I already post before here the picture but here it again

Venting my lid for better airflow is good enough for me, bodies get trashed too fast to consider fabbing legit 1:1 style intakes. It already takes too much time painting lida too...

That scoop looks good, but think abut it, it would be hooked up the the throttle so itll open when u pull the throttle, as long as the ports on it add up to the same size as the carb( or bigger) it wouldnt restrict at all. think of it like the scoop on a car, they designed it to alow the airflow, not restrict it. would be te same idea, and it would have to be mounted off the chassis so if u removed the body it would all still be intact. I'm the big mechanic type, so i guess its just a vision till i make it a reality. Would have to get some parts and try it out.

Restricting airflow from a nitro motor is just stupid, why would you restrict airflow when the rig is at closed throttle idling & still drawing in air (or trying). With restricted airflow will drastically change run temps, performance & the ability to hold a solid tune.

This sounds as tarded as people that stupid-charge their nitro rigs and think it was a great idea. MY. 02 is that it wont work efficiantly.

Who said it would completely close when it idles? one on a vehicle doesn't close when u idle its open allowing airflow, saying something is "tarded" just means u r ignorant to what actually can be done. If you dont know basic mechanics, i dont need your two cents. U must drive a prius, or some type or foreigner car. Anyone that knows how a carburetor works can make something happen. This aint no fuel injection. And to say supercharging doesn't work clearly shows how oblivious you are to physics. It may not be how it is in a actual vehicle where with the right tune u can boost an extra 100bhp and around 150lbs of torque(talking about american now, not wussy tuners).But when you scale it down to how small these engines are it would scale it down. With it tuned right you can probably(notice that word probably) get a little bit extra. Dont knock anything down just because you have never tried it, or can't just understand how anything actually works.

Lol throw up the verbal fists over my .02 cents aka my opinion, good stuff man
Even if the intake isnt closed all the way, if its citting off more than idle airflow amounts thats the first place youll go wrong..

It could work, who knows but a nitro engine is alittle more sensative to minor changes that alter the existing factory performance. And when I talk about supercharging or adding forced induction I'm not talking about 1:1 vehicles lol I'm talking about charging nitro engines... I know forced induction works on 1:1 cars because 1)I'm not stupid & understand the physics of an engine(used to drive a WRX) . And 2) I'm not some noob teenage kid who talks bs out his ass, I'm 26 with a wife & kids...

Oh and I drive a Toyota 4runner because its great offroad and oh, plenty of room for my family... So if you want to keep your poor attitude when people post THEIR opinions whether good or harsh, then good luck getting help down the road...

Oh PS, if you truely believe superchargers work efficiently on nitro rc engines your a damn fool who shouldnt be allowed to enjoy this hobby.

Don't forget about the boost bottles too!! Those work 2X better than any stupidcharger on a nitro rig!!

Wow, 9 whole posts and already bashing respected members who were trying to help you; you're really off to a great start. Also, calling someone ignorant in a post that's full of bad grammar and punctuation is sort of the pot calling the kettle black, don't you think? How about you take a deep breath, relax, and listen to people who know what they're talking about. Superchargers on these small two stroke motors DO NOT work, and are a quick way to kill your motor and empty your wallet is all. But by all means, if you want one, go for it, it's your money.

Murica!

Hey hey, we were pokin fun, we already kissed and made up now, i know they dont make anything for these engines like for actual vehicles, the rpm are way to high for forced induction, but u gotta think, wat if someone actually made something to work for it? And i know the grammar is kinda bad, but I'm using my phone, and I'm a mechanic, not an english major. But back to the subject of debating why it wont work, i can see that the carb is already almost closed at idle, but if the scoop was a big enough scale to allow enough air to flow with out closing all the way it wouldnt interrupt the airflow in the carb, would it? I mean if I'm actually wrong about it, which is possible, and i know they are sensitive to small changes.

 

[HPI-Killer]

Kiss and made up, hell no.. Were grown men, we discussed and resolved

I would like so see air vents open and close with throttle punch on a super charger style blower, even if was just cosmetic would still be total badassness.

 

[Jeeprider]

Haha, u liked it, dont lie, but i will see wat i can scrounge up, make it cosmetic first till i figure out how to measure the airflow going through it.

 

[alpinehyperlite]

Question in the back!!!!

Assuming that there will be no pressure issues (which I believe there will be some unless the flapper and scoop are enormously out of scale)

Where would the filter be?
Will the scoop be mounted to the body?
How will you seal the carb intake to the scoop?
How do you plan n keeping dust/debris out of the intake from the scoop?
How do you plan to open/close the flapper? Mechanically? Separate servo? Using the negative pressure of the motor in taking air?


I just don't see any way that this will properly work. Even if engineered perfectly, I don't see any possible gain out of doing this. And yes, I know mechanics.

 

[HPI-Killer]

Okay Alpine we know you know the mechanics on your radar gun & siren/flashy light control panel...

But what about a shot of NOS & one of them fancy soopercharger doohickies, gotta take that into affect too ya know.. Its not all bells n whistles like your cruiser

 

[mayrider]

a buddy of mine uses a 90 deg piece of pvc that slides over his air filter of his JATO(granted he doesn't run a body) i could see someone cutting a thin metal flap to go in there to work as the butterfly getting the linkage to work might be a challenge though. as for at idle you could drill a couple holes in the butterfly to let air in at idle.

 

[Alexander_0_1]

I toyed with this idea a while back all I came up with is ram air induction that works better for high speed pavement runs?. The way I did mine was with funnelled PVC that I cut to fit the inside of the body, I quickly glued on some window screen to the funnel PVC to keep large rocks out, then I cut out the front window, and that's how I put ram air onto my savage xl body...I didn't fasten the funnel PVC to the body, I zip tied it to the roll bar.

The way I did this allowed me to use the entire cab of the lexan body as a ram air, I never thought of making it open and close, with a butterfly gate valve, though: who's gonna see that open and close when it's 75' away and pullin 45mph, it could get jammed up during a race/bashing session with any number of things.

When it's sitting on the bench with the engine off, squeezing the throttle trigger will make it look really cute.
Once you start the engine it becomes meaningless.
Here's one already made. It spins the pulley so it looks like it's running. :whhooo:

It might be a little small. It's for an X-mod.

That might look cool on my Mini-z stuff.
