So just PLAY along with me here for one sec. And I mean the serious guys that have tuned as well.......

Say for s***s and giggles I created a "parascope" intake on a completely stock S2K. It would consist of a short tube connected to the throttle body, stick out the top of the hood a couple inches, and bend forward where the opening of the tube would sit horrizontally facing the front of the car. This would create the ultimate ram-air situation.......following this line of thinking, as the speed of the car increased so would the dynamic coefficient *(psi).

THE BIG QUESTION: Is it possible to go TOO fast (100-160mph) in an S2K and and ram too much air into the engine? Wherein a "Lean Moment" would occur?????? Would I have to be prepared to tune my ECU under such conditions?

Go easy on me guys, this is purely hypothetical at the moment, and I'm simply wondering if this concept has its validations.

Hit me with your most technical opinions, the more the merrier!

 

no the car would compensate if this did occur, your not creating boost

 

A friend tested ram air on a Pro Mod drag bike using the area behind the front wheel to catch air. I dont remember the details but it did nothing worth while, even well over 100mph. You will get cold air but thats about it.

 

Wow. This is almost as funny as the DEI guy.

 

Thanx


But think about this:

@ at altitude of 300ft & 80mph there is a dynamic pressure of 16.2091 lb/ft^2

@ at altitude of 300ft & 120mph there is a dynamic pressure of 36.4913 lb/ft^2

@ at altitude of 300ft & 160mph there is a dynamic pressure of 64.873 lb/ft^2

CARB legal vortech kits average between 6.5-9 lb/ft^2
Typical turbo kits range anywhere from 6-15 lb/ft^2


Essentially speaking all of these systems are performing the same essential task: Forcing air into the intake of an engine.

The only thing I can see that would prevent a snorkel from working similarly to a supercharger or turbo is the lack of compression pushing back (enclosed and pressurized turbine(turbo or super)) into the intake as the engine valves close, creating a momentary compression build up through the intake. If this was indeed the case, it seems that the snorkel idea would NOT work because there is not enough counter pressure to keep the intake tube proportionately pressurized in comparison to wind speed.

Interesting...

 

To sum it up its not gonna work.

 

Thanks for this link, very helpful! Thanx to everyone for their opinion!

 

The data for the super- & turbo-charger kits you quoted have the wrong units. The nominal boost pressures you list are actually in lb/in^2, not lb/ft^2.

It takes 144 lb/ft^2 to make 1 lb/in^2. So even the highest ram air effect you are quoting is less than 0.5 lb/in^2. So you are not creating much boost pressure with ram air.

Even that small amount will help the engine breathe more air. But the magnitude is a much smaller effect than you are thinking. More like changing from a dirty clogged air filter to a good CAI. Nowhere near like adding a supercharger.
