Custom Power dome cowl

hey guys some i have a powerdome on my 02, im thinking about(and have been for a while now) either drilling holes or cuting a section of the hood it will be on the back side that faces the window making it a cowl of sorts. i have noticed rangers hold a ton of heat under the hood and think this could help get some out and make it look cool.

option 1
if it drill holes i plan on staggering them like so:


. . . . . . . . . . . . . .
. . . . . . . . . . . . . . .
. . . . . . . . . . . . . . . .

option 2
cut out 2 sections leaving some in the center for ragidity and lay some mesh down on the inside so no nothing gets sucked in. possibly do 4 sections instead of two but in the same manner.


option 3
leave it alone. i have already laid some falt black donw on the high part on the hood and it looks good!


shoot me thoughts guys, i plan on doing what ever it is i do tomorrow 5/16/10

someone (i can't remember which forum site) took and cut open the entire back lip of their powerdome hood (facing the windshield) it looked pretty cool, and they said it was functional.

Very nice. I'd try the holes first to see if the airflow improves a bit... then you can cut the holes like he did if you want.

Testing out that theory on an older model STX, raised the hood one inch off of the hinges and it cooled the engine by 10 degrees.

can someone post a pic of the window side of your powerdome hood? i don't seem to remember it being raised up like that on my 07

as for the comments in the other thread about smelling the engine, and defrosting the windows, you won't see any of that, as that will pull air INTO the engine bay, decreasing the vacuum (and thus hightening the pressure) of air in the engine bay, reducing stagnent air... the air hits the windsheild and gets sucked forward while driving, you may have heat coming out of there when stopped though... and you may have issues if you hit a puddle and the water steams on the exhause (with the outside of the glass fogging up, if you are driving slow)

ROFL~! Also, our powerdomes are ALOT more pronounced than those wannabe powerdomes found on 04+ trucks...


I think RangerExtreme(scotty) also did the mod to his old hood(now owned by Sully). I've been pondering doing it for a loooooong while now. Just don't know when I'll do it. lol.

none of those problems would be present with a proper functional cowel, as the opening is sealed to the airfilter housing/intake, so the heat from the motor wouldn't be coming out the back, as is the intent for the ones done on the power dome hood. and i wouldn't really define me stating the drawbacks as worrying

Most real cowl hoods are not sealed to the intake

then they aren't functional, the purpose is to force air into the motor to improve horsepower, ask me how i know, i spent several years learning about exterior car design functionality, and several months making a custom cowel hood and "ducting" on the 81 camaro i used to drag race

works the same (once the air is inside the scoop) as a ram air hood, most of the cowel hoods you see on mustangs and such are put on for extra clearance for a larger motor

UMMMMMM.......weasel....


A cowl and a scoop are two different things. A cowl is to release all the heat in the engine bay, thus cooling down temps and the less heat in the engine bay and on components, the more power the engine will produce(cooler, denser charge). A hood scoop is to shove air into the intake. With a cowl hood, it doesn't suck cool air in, it sucks hot air out!

apples to oranges...

ummmm, shane, no... that is what you can use it for, but is not a functional cowel hood,

here you can see the weather stripping at the top of the air filter housing, to seal the engine off from the cowel area, and can see the opening at the back of the hood

seen here as used by nascar

seen here on the 69 yenko camaro



shane, maybe you shouldn't let that bulldog mouth overrun that puppy dog ***
