As the title said...

I've gone through the forum search and can't find a conclusive answer.

What we sayin then:

• 1 cold air intake
• 2 cold air intake's

Anybody had a go with both methods and found the "ANSWER"?

Should be an interesting answer....

 

Single induction is better for a single throttle body. Two pipes going to the same place causes too much turbulence before the MAF and a loss in HP. Also the filters need to be located outside the engine compartment or they are LOSING HP.

Anthony,

With all do respect, there have been many discussions on this topic and it will never be put to rest. There is a member or two that have a good dual set up that have proven on the dyno that there is no noticable difference between the two, in fact if I am not mistaken, the dual proved better on his particualr set up. The filters were in the engine compartment as well. I do not want to start the whole thing all over again and would imagine everyone is just plain tired of this topic but at the same time, I would not want to see someone mis-lead just to make a sale.

Having the filters in the engine compartment is bad. Just take the temperature with an IR thermometer of the engine area where the intake is in the engine bay compared to outside the engine bay and there's a huge difference.

 

Your right Daniel, it is not ideal. My point was more directed to the twin compared to the single.

For the SRT6 a dual or singel set up will produce similar results due to it being FI and the sensors in different places. For eh N/A car Single is better. Show me one test that proves other wise.

 

Actually, Anthony, again with all due respect, lets see a test that proves that a single as opposed to a duel, does in fact add more horsepower ! I've seen the setup you guys sell and I've seen the custom designs that forum members have fabbed up, both claim horsepower increases. Which is better ? I was reading just yesterday that removing the plastic tubes to the air box adds 7 horsepower. Minimal for sure but 7 horses is 7 horses ! But this kinda disputes the idea that a CAI is indeed needed to add horsies to the N/A Crossfires. Dyno sheets would be a good thing. Again, I'm not tryin to be an a$$, but rather somewhat confused.

Just my Dos Centavos !

 

Plastic tubes you mention.... ?

Do explain...

I'm not sure about the N/A Crossfire - but the SRT6 has a black plastic screen sandwiched between the throttle body and the supercharger - I don't think you could get a finger through it - so much for the need for smooth undisturbed intake airflow.

Also, when LET removed the tubes on the SRT6 while it was being dynoed; the hood was more then likely open at the time.

There needs to be a Intake dyno shoot out.. Same Car, Same Day, Same Dyno....Both for the N/A and the SRT6..

Hello Anthony...We'd talked on the phone the other day(2 weeks ago) regarding the exhaust tips...Was calling from Cali,just bought xfire,and was curious about the engine valve dressing that you had on your TVTsite...Glad to see you here !

 

I built my own short ram intake that puts the filter, just off to where the radiator fan is, under the engine bay. Anyone who says you loose power not having a CAI is lying. I got much better throttle reponse and torque, and a bit better passing power. It also only cost me $150 VS the other outragous prices of the intakes for our cars and installation is more simple. Also no possible worries of hydro-lock.

 

GOT PICS ?

 

I decided to go ahead and make my own tutorial in the TSB's and How To forum to answer any questions. Thanks.

 

I'm wondering... Where is the sensor for the outside thermometer located?

When the car sits it builds up temperature. I notice that once I start moving, even slowly, the temp goes down very quickly. Might this be an indicator of how quickly the hot air in the engine compartment is exchanged? Let me add, that I removed the baffles that hold the stock air tubes in the front. That lets in more air.

Another question is just what is the power difference between hot, warm and cold air? Sure, the hotter the air, the less oxygen, but is there any hard proof of how much that really affects combustion, or is this to some extent just a case of everyone accepting things, because "thats how it's always been"?

 

The outside temperature sensor is in the lower left hand grill.
Look closely and you can see it sticking out.

 

Looks like a mech.pencil sticking out about an inch.

 

Fellow NA m112s,

I havent had a thorough change to read through all of the ideas presented regarding different intake setups on these forums, but has anyone tried to run two pipes (from each intake area in the front of the car) to one large filter then run a pipe frome there to the MAF (for NA cars)? hopefully all of the turbulance will occur where the big filter is and will be straightened out by the time the air makes it to the MAF.

ps - hello from the mb side of m112s :P

 

A COLD AIR INTAKE SHOOT-OUT... GREAT IDEA!!
