Why can't the AEM Air Bypass Valve be used on a forced induction car?

YES, I would also like to know why too.

Heya Drizze n Tom,

This is just a shot in the dark man, but perhaps the volume of air that gets sucked into the inlet side of the turbo is entirely too fast (vs. N/A cars) for the AEM BPV to be able to function correctly. My guess is that if water caused that vavle to open that it would be rushing thru it so fast that the motor would still injest water.

I thought that it would be a good investment for a CAI system on our cars.. who told you that it wouldn't work on forced induced cars?

i think your pretty much correct. here's how i look it at. When your air filter gets submerged in water, it creates a bigger vacuum in your intake tubing causing the bypass valve to open. Now with a turbo, there is already so much vacuum in your intake tubing that it's gonna cause the bypass valve to stay open all the time, which is not what it's intended for.

That was my thought as well, but almost every site I went to that sold it said that it is not to be used on a turbo engine.

Bing Bing Bing.... I think you have something.

You got it. Once the filter is submerged the bypass valve cannot support the airflow for a forced induction vehicle.

Thank you to everyone that answered!

Can AEM develop a solution for forced induction cars?

AEMTech · 03-05-2004, 10:46 AM

AEM does not recommend the use of the bypass valve on engines equipped with forced induction (turbo or superchargers). Additionally, using nitrous oxide in a placement before the bypass valve is dangerous due to fuel contamination of the foam spring/filter as well as degradation of the integrity of the plastic due to the extremely cold temperature of the nitrous oxide. Nitrous can be used downstream of the bypass valve.

Are there any plans in the works for AEM to produce a product similar to the current bypass valve, only for forced induction or other high-velocity intake applications?

Not in the near future.

I think it's because that there's a lot of idiots out there that put scoops and seal off the filter for their cold air into a scoop that's down low and very narrow, which can be completely filled (even for a 1/2 second or less) with water and create a hydrolocked engine.

However.......if you're a company and you hear of things like this, you'll make a vaccume based valve that'll open when WATER AND ONLY WATER fill the tube, allowing the air to be sucked through the valve and allowing the water to drop. This creates an extra revinue.

And yet, there are people like me, who have been running CAI's in literally monsoons that come out with just a wet filter....and that won't hurt a damned thing.

You only have to worry about this if you're going to bottom out the car (like the ghetto intake system someone posted a looong time ago), or if you have the filter up in the fender (like mine, but looking at the foglamp hole) 1/2 way up your door.

I personally don't buy AEM's story with the forced induction cars. Why? Only an idiot would be mashing the throttle in the rain, the rest of us drive and try to put as little power to the ground as possible to avoid accidents. Airflow requirements aren't that big in low power/low throttle conditions in turbo/super applications.

If you're still paranoid for no reason, just buy 2 or 3 of them and put them in and call it a day and look at the $150 that's missing from your checking account.

was it really necessary to post this same exact post twice, in two seperate places?
