I had to replace my water pump so while I was waiting I decided to try the 4" hose idea ran from the camaro bumper holes behind the grille to the airbox. EXCEPT I USED 6" HAHA.

I cut away all the metal under the airbox (grinder with cutting blades) from the support brace except for a small portion on the front and it is still rock solid. Also keep in mind i have no bumper supports, ac, washer fluid, hood latch, etc.

I sealed it all up with silicone and made the plate out of sheet metal to hold the hose with basic tools (dremel, snips). Used 6" hose i bought from Lowes and painted it black. For anyone looking to do this theres a 100 different ways to go about it, its all just trial and error and how you want it to look, originally I was going to make a ram air box around the hose as well but I gave up on fabricating that as it would have taken me a week lol.

So here we go with some pics, used my cell camera as my wife took mine today. They are small...sorry.

 

not bad man, hows it feel on the road?

 

Just finished. Still waiting on my water pump which when I ordered they neglected to mention they were out of stock so hopefully bu early next week.

 

ok, maybe not as good of an idea as i thought.....cant hurt though seeing as alot of people liked the 4" hoses version.

 

you need better pictures...i cant see ****...

 

Maybe these are a little better.
Waiting on my bumper to come in so thats why its not on.

 

Neat!

 

As an added bonus I just added my tranny cooler in between the two hoses at an angle (from the hood latch to the lower radiator frame) to pick up max airflow off the air dam deflector. Was a pain to run it to there but looks much better.

 

update when it is all finish looks good though so far around the same air flow i got though mine...

 

Better pics finally got my camera



Black tape in those areas was to cushion those spots against any metal


B&M cooler in the middle

 

looks cool... i wonder though if all that is gonna block any air from getting to the radiator?

 

his ac condensor is gone, the radiator is getting plenty of air

 

Pretty slick setup.

 

I'm gonna do this mod over the winter. I think I'm gonna go with 4" though.

 

I'm suprised no one has said anything about heat soak for once.

 

I was gonna say the same thing. I wouldn't be surprised if in the summer your not getting a lot of cool air from the a/c.
The setup looks good though. Wish us goat's had something to make a functional ram air.

 

what kind of tubing is that?? And Does anyone have any track e.t gains from doing something lke this???

 

Ya heat soak will definitely not be an issue.

Got the 6" tubing at lowes.

Gains are ".1 e.t. and 1 mph" supposedly. Its definitely better than what it was....

 

i gained around 20-22rwhp over stock with no ram air at all...(ie including free ram air)...i have proved it in multiple past posts if you are that interested search my name i am too lazy to look it up...also gained around 10-12rwhp over a FTRA setup...i used to have that too before the huge ram air

 

How does a dyno pick up those kind of numbers considering you arent moving forward "ramming" air in there?
