Where can I get a CGS intake and is it expensive?

 

what kind of gas mileage do you get with the CGS and Cat Back?

 

very interesting..

 

Good thinking on the intake. The owner of the "other" forum did something similar with metal piping a while back. Same concept.

Looking at your system, my engineer brain began whirling. Two things to ponder for you. 1) you need some sort of simple bracket (maybe trapped by the hose clamp) that keeps the filter from bouncing around in the wheel well. And.... 2) That wooly worm will not last long at all passing through that sheet metal wall. It'll most likely wear right through quickly. A piece of metal pipe and two hose clamps will fix that. Make sure the metal pipe is through the metal fender well, then cut the wooly hose and add a hose clamp on either side of the hole. Alternately, you could slit a small rubber hose lengthwise and make a gasket around the fender well hose. The metal tube is the better idea IMHO, though I'd do both!

I have been running with this mod now for about 2 months. I zipped tied my filter in place to stop it from moving around in the wheel well. Unfortunately my MPG's has not changed much. I think maybe about .5 mpg better at best. On the highway with both the CGS intake and muffler I'm getting about 32.5 mpg on the freeway. That's up about 3.5 mpg before installing those.

 

The question that comes to my mind is, wasnt the idea of the weapon intake to eliminate this hose in the first place? The OEM intake brings air from the same place, no?

 

Hi Prod, It baffles me that folks try to eliminate the wooly worm hose. After dyno testing, the wooly worm was found to not be any restriction at all. In fact, if you take the wooly worm off, and let an intake breath underhood hot air, you lose horsepower. Think about it, if the wooly worm was a restriction, do you think it would have cost GM any more to install a 1/2" bigger diameter one?

The point of the wooly worm is to allow cool outside air to get to the air cleaner. It does that job. Any aftermarket intake system that breaths underhood air MAY be less restrictive than the Helmholtz silencer arrangement of the stock plastic intake, however, if the "improved" intake setup breaths underhood air, you are basically erasing the gains from low restriction. That is why the K&N and GMPP intakes are top performers - both enclose the intake filter element from underhood heat, and both breath cool air through the wooly worm to the fender.

There were questions about the wooly worm being restrictive, but Hib Halverson's recent dyno testing proved it is not a restriction.

Your idea of a filter in the fender was (I am sure) considered by GM engineers, but was most likely discarded due to it being even harder to check and change than the diabolical factory plastic filter housing. If you can make it work, all the better. I love my GMPP Intake. No codes, no oil, more horsepower, cool sound, breathes outside air, looks good, well made, easy to change the filter. Downside - it's hard to get now and is $400.00.

Clear something up here..Hip didn't say it was restrictive..he said it flowed the SAME as it being disconnected.That said, it only means that there is no change with that configuration..as for being the correct diameter? GM would definitly skimp here for a few dollars times 10,000 vehicles. It doesn't imply that going to a larger size tube will not yield any benefits, I believe that from what I have read here it does, as with most vehicles. GM's intentions are NOT to build the most performance out of any engine,,it has to meet all the piddly EPA requirements and that usually means a smaller intake and exhaust ( which is cheaper for them also).
Keep the stock box and enlarge the inlet hole and hose and see what happens..if possible enlarge the pipe all the way to the TB/Turbo. You can never have too much air in, but too little always has a negative impact.The people claiming gains are flowing straighter piping and less routing restrictions, this should be a clue as to what direction to follow.

 

Hi Woody, Hib installed the higher flow K&N enclosed aftermarket intake filter and housing system. He tested it with and without the wooly worm (with the hood UP, note that) and found no difference. If the wooly worm gives the same flow with one of the highest performing intake setups, do you need more diameter? Also, there was no difference with or without the tube.....so does that mean the tube is a restriction? It may be that tube can handle more than the rest of the intake. Hard to say, but it doesn't appear that the wooly worm is the weak link in the chain. Adding a huge diameter replacement won't yield any benefits unless you remove all restrictions, and only then if the engine itself can use that much air. These aren't big engines we are dealing with. I agree that in theory that a straight path with big tubes feeds an engine better. However, I think most of us are working within the limitations of lots of factory parts on our HHR's, and the wooly tube does not seem to be a power-sucking culprit.
Also, note that the dyno runs were done with the hood up, so the engine got cool air with or without the wooly worm. If you are breathing underhood air, you are losing power or any gains from an aftermarket intake. BTW, this is the first cool weather that I have had my HHR...and I sure can tell a power difference on cold mornings. Not trying to be argumentive or disrespectful Woody, just discussing car parts.

I didnt want this thread getting into a flow discussion match. I just did this to help colder air get to the engine WITH THE CGS INTAKE. not the gmpp or k and n. I got rid of my stock intake flow wise or not, for the throttle response. With the stock intake on i just feel held back.
