Very cool mod...Neat & clean..

1 question: Did you experience any motor temperature difference ??

 

^ i haven't really noticed any difference ( DIC is about the same ), but i wasn't really concerned about " cold air intake" . i did this with appearances only in mind. besides, if you want performance out of an hhr... well you know, get an SS

 

That's good, cause it does look clean & old school...

I don't think the only HHR that has performance is the SS.

Plenty here that are modded up, for increased power...

 

I would have to guess the OE setup was designed by some german guy who used to overengineer things for BMW.....nuff said

 

Black Rose- Thanks for great write up!

It "only" took me about 10-15 minutes. Without your how-to and pics it probably would have easily been an hour -gingerly trying to take things off without breaking them, or removing screws that didn't need it...

Plus step one was already done-the intake tube was just laying on the fender well, instead of attached to the sidewall (by the grommet).
I'm not sure how long its been that way, but I nudged it back in and will keep an eye on it.


Thanks again! It is one of the many helpful examples on this site.

 

If you install one of these the filter change is MUCH easier. :-) God Bless, Marc

 

Now change out that wolly worm restrictor tube you have and it wil be even better.....

 

Roger that, but to what kind of tube? It has to be a flew tube. Also, it is only going to flow as much as comes in each end, so I would have to get a bigger inlet flange welded onto the side of the airbox if I went with a fatter pipe, as well as a bigger hole in the fender wall. The flow is only as good as the smallest restrictor. Ask the restrictor plate experts in NASCAR. Right? God Bless, Marc

 

Ummm....make that "what kind of FLEX tube?"

 

Actually according to Bernoullis' principal of "Venturi Velocity":
http://en.wikipedia.org/wiki/Bernoul...ld_application

You can actually speed up in-coming air by running it thru a 'venturi' or smaller hole (if you will) then into a bigger pipe.

"The flow speed of a fluid (which air is considered a fluid) can be measured using a device such as a Venturi meter or an orifice plate, which can be placed into a pipeline to reduce the diameter of the flow. For a horizontal device, the continuity equation shows that for an incompressible fluid, the reduction in diameter will cause an increase in the fluid flow speed. Subsequently Bernoulli's principle then shows that there must be a decrease in the pressure in the reduced diameter region. This phenomenon is known as the Venturi effect".
