Made my cowl hood functional

[otter1363]

Sheetmetal, tin snips and an aircleaner... (oh - and pop rivets)

[LETHAL HEMI]

thats badass....

[adamsredlines]

It looks good but I would be worried about it kinda starving the engine...?
I know how a cowl hood works butarent they more open than that?

[otter1363]

I am sure there is more open SA in the hood intake than in the 3.5" tube. The area in the opening is 26" wide x 2" tall

nice work

[Jacked Hemi]

Awesome work! I made a 2 piece system like yours for my srt10 hood. Stay away from deep puddles and you should be fine. :finger2:

Do you hear it more being it's closer to the windshield?

[otter1363]

I dono. Keep cooking my #1 coil every time I start the truck now. Think I tosted my PCM hacking and slicing the injector/coil harness. I'll let you know if i ever get the fucking thing running -

[Onebadbee]

haha you need more vodka

[otter1363]

yah, enough of that - I switched to Jack now...

[Gary's Hemi]

pretty cool

[Hemidup]

Yah - I think one of the LX guys did a set up with that intake. Not sure the details but they used adapters and TB's. Must be a mess to get functional...

[Onebadbee]

ya must be a mess

no genius on fluid dynamics, but wouldnt it form a vacuum?

[otter1363]

You mean the hood -? In a nut shell it creates a high-pressure area between the back edge of the scoop and the windshield. Air flowing over and around the Hood is turbulence which packes air Back in towards the scoop. Same type effect that pulls air into the back slider window of your truck.

[sldhemi]

Yea the idea of a cowl hood is that not all the air to hit your windshield travels up. Hence the vents directly under the windshield wipers. The motor forms a vacuum in the scoop and pulls in w/e it can from the scoop

[tajm]

I was thinking hood scoop. I think they proved it actually forms a vaccum being so low. Same as a sunroof. The air get sucked outside. I could be wrong, just always curious.

[hemi1569]

looks great, how does it perform?

[otter1363]

dono yet - havent run it.

ive never seen or done any tests on it myself... just always gone off the "theory".

in theory velocity stacks should have the same problem, granted theyre not the best form of air induction but theyve been proven to be great performers

[tajm]

They work according to the venturi effect. Which is my reasoning that it would form a vaccum that low on the hood plane. Again, I may be wrong. Just something I always wondered.
