SHAKER air flow

[Chryco Psycho]

I am sure it was designed in a hurry & with a limited budget , not a bad idea overall but the engineering could have been better !!
 I have often been surprised by how much air even a small scoop low down within the useless boundry air can bring in  . I drove a 67 coronet with the Hemi scoop on the hood sealed to the Air cleaner in sub zero temps , this is the factory Hemi scoop , not the taller SS hood so it might have been 1.5" off the hood & after 20 mins or so running on the highway @ 70 mph the car was running very poorly , so I pulled over & popped the hood ...... the alum intake was ice cold running at 2500 rpm so the fuel would not atomize LOL

Thanks for all the input guys. You kind of reinforced what I thought was the case. I don't run the car at the strip just terrorize the neighborhood and from time to time kick the a$$ of a Mustang so I guess for now I will just weigh performance against cool. Weigh, weigh, weigh,---SHAKER wins!!!

Actually this is a timely topic for me. I am running a Stage V intake on my Hemi and had to build a drop base aircleaner to fit the scoop correctly. I have been tuning it and it runs like a raped ape with the aircleaner assy off. With everything installed she loses about 100HP. I am thinking I now have to space the darn scoop up so it sticks out of the hood more and then space the filter up as well because I think it isn't flowing.
I am buying a wideband before going any further though so I'll run it with the shaker setup on the way it is now and see if it's going really rich with it on.

looks like your shaker assembly seals to the hood. When air moves across hood,
you only get a positive pressure at the part of the hood near the windshield, so
your airflow over the hood, where the snorkles are, may even be giving you a negative
pressure there ,ie ,restricting airflow into your carb.

Maybe you can get creative with some of these parts?

Having a shaker, but not being a engineer and by observation only, the shaker in its stock form prob does not have allot of air flow as we would like to believe. 

 Keep in mind I have a four barrel shaker  (and the small round air cleaner) , but I run a KN top instead of a solid filter lid to help improve on the design.   

I beleive the cooler fresh air is about the only real benefit as opposed to actual air flow

But the PIA factor is high when you have to remove it 

  But the cool factor overcomes all negatives

If shaker turned 180 degrees, placing the snorkles
at the windshield base, might get more air flow,
like a cowl induction system. I think the Ford
Thunderbolts did that.

I think thats why Pontiac put the opening of the TA shaker in the back by the windshield.
and the L88 hood on the Vette and the Cowl hoods on the Camaro and Chevelle where all in the back.
Pressure is correct by the front glass as vehicle speed increased.

I own a N96 challenger and gotta say it is a real PITA to deal with from a tinkering standpoint and can tell you 100% for sure that with the bubble out and the carbs open to the hole in the hood the damn car screams....   :-)

Nice idea - poor implementation

Definitely cool but also a PITA. You cant get to anything without removing it. Only takes a socket and 3 minutes, but still.
Maybe made the bubble taller?

I was thinking that as well.

Too much higher and it might look kinda wierd.
Some photshop or CAD work to create possiilities might be a good idea.

Any takers?

[Chryco Psycho]

I believe a better shaker could easily be designed , wider would help higher would get out of the boundry layer but keep it looking stock ish unlikely

I thought that I read somewhere that in order for an air scoop to really work from the hood the opening had to sit about 2" above the rest of the hood.

[cudabob496]

Ya, a shaker hood scoop that was 2 inches higher might really increase air flow.
Saw one on a 2014 or 2015 modern mopar.

I'd be trying to make a ram air system with tubes going to bottom of shaker assembly
under the hood. Something like this, with the Shaker sitting on top.

Im going to start working on my ram air (turbo) set up this weekend. Im sure a thread will be opened on it in the coming months as I get all my finalized measurements down.
