Snorkel to CAI to Supercharger compatibility

What whipper said. The filter dosent really affect the boost and power levels until it starts getting really clogged. Its more like trying to breathe through a straw while running. The supercharger just cant suck enough air fast enough through the snorkel from what I can tell.

 

There is airflow being limited and the stream of airflow is disrupted by any/all air filters. It may be marginal, but it is a fact....not an opinion.

We can speculate that it wouldn't make a difference, but who are we?

Any scientific test needs to be done with the SAME baseline otherwise what is the point?

IMO that video is bullshit if one test has a filter and one doesn't.

 

x2. IMO you have to perform the test as closely as possible minus the part you are trying to prove causes the power loss. He is pulling air straight into the S/C. No one in their right mind would drive like this because of the chances of getting dirt and debris into their engine. He needs to do the same test with the snorkel vs CAI or stock intake to make it more reliable and applicable in real world driving situations.

 

There is a guy on this board who plumbed his snorkle into his AFE CAI and with only the CAI (lid off) the supercharger was pushing about 5.5 psi. When the lid was on and it pulled air directly through the snorkle (with CAI filter still in place) his boost dropped to barely 2psi. Thats pretty good evidence to me that the snorkle is highly restrictive.

 

I haven't said, nor do I doubt, that the snorkel is restrictive. My point is simply that the video shows the snorkel with a filter vs air being pulled directly into the S/C. Although the differences may be negligible, a stock intake and AFE CAI still have restrictive tubing, airbox, and filter. In order to be as reliable as possible, the test should have been performed with some type of filter in place simply because no one would ever drive on the street without protection for a $4000 S/C or an engine.

 

Ok, I agree with what your saying on the respect of not driving around without a filter. BUT as whipper said, the new filters (Lets say AFE CAI w/ Pro dry, thats what I am running) wont cause much of a drop assuming the flow isnt restricted into the airbox. There is enough surface area on the new filters that it shouldnt cause much if any drop across it.

 

Ok so lets all agree to agree

Anyone who wants to be credible needs to follow the scientific method of testing not the hillbilly way

 

AGREED! Thats why I dont own a Heep...

 

So I think I am going to at least get and install the snorkel for the moment. I won't plumb it into my CAI but will just cap it off inside the fender for the moment. I want to get a 2nd CAI box so I can modify it in a couple ways.

I am going to give this a try, I think if the snorkel does in fact cause breathing issues with the supercharger I will plumb it into my CAI, seal it, and then get 2 different lids for my CAI.
One will be the stock CAI lid that I can put on to seal the entire unit and make the system breath through the snorkel when I am crossing streams and such.

The other will me a modified lid with most of the lid removed and just a mesh cover. This is will allow the system to breath freely through the lid and will still be filtered by the CAI.

I will monitor performance as well as intake temp and others. I have the supercharger intercooler so even by pulling air from the engine compartment it should be somewhat cooled by the intercooler.

The way I look at it, I will only need the sealed CAI cover when I ford water and in that case I won't be running high RPMS's and large amounts of boost so the loss of boost from pulling through the snorkel shouldn't affect me to bad.

 

UPDATE, Does anyone know if Delmarva got his snorkel installed and dyno runs done???

 

did you pm him?

 

I did but I thought I would revive this thread as well.

 

100% true^

i look at my snorkel as a way to protect the engine better not increase its performance.

if i where the op i wouldn't worry about mating a snorkel to a cai and then to the charger i see no point in it. run the factory air box use a high flow air filter preferably a dry model like the afe then slap on the charger and call it a day.

btw, the modifications needed to make a cai work with a snorkel is more than one might think and it really won't make much of a difference if any at all.

 

Your assuming I have the original intake to begin with. I am not looking for performance gains so thats a moot point. I know what entails plumbing the snorkel into the CAI so again, thats a moot point.

What I am interested in is any performance drop of running the supercharger and snorkel together.

 

I will be preparing car for with SC and because of racing routes characteristics in my country (water crossings) I need a snorkel. I don’t want to compromise to performance.

Do you think that larger diameter of custom made snorkel connected to CAI would prevent major HP drop?

 

There used to be an airbox mod called a deck plate mod, although i don't see it mentioned very much these days. The gist of it is that you drill the airbox and install a deck plate. Need more air? Unscrew the plate. Need a sealed air box? Screw the plate back in.

No shit.

If you read the rest of the thread you'll realize the dude isn't a retard and can put two and two together...

 

Deck plate mod is for 1st gen.

 

I could be retarded, you never know!!!

And no, the deck plate mod wont work.
