OK, so it sounds cool to have your exhaust system sound like a jet engine at the touch of a button. Its even cooler that while that's going on, there's an interfreezer under the hood chilling your intake air. But, there's more to it than looking and sounding good. Its about horsepower. Its about increased throttle and boost response. It's about the hottest, most innovative product available in the automotive aftermarket today.

First, there was supercharging, then turbo charging and...now... flowcharging. Introducing, the Flowducer.

What is a flowducer? Basically, it is a device whereby compressed gases are introduced into the exhaust system, creating a negative pressure. That's right. A flowducer uses a pressurized gas to create a vacuum, thereby more effectively evacuating spent exhaust gases from the engine. That means no matter how good your header design is, no matter how big of a downpipe you have hanging off that turbo...none of them can touch the flowducer.

How does it work? A system of tuned orifices on the trailing edge of the wing shape expels compressed CO2 at a very high velocity. As the exhaust gases mix with the higher velocity CO2, they are accelerated. This creates a positive flow across the flowducer and lowers the pressure within the exhaust upstream of the flowducer. When the pressure within the exhaust system is lowered, the spent exhaust gases travel more quickly and efficiently from the engine. This increase in efficiency not only helps the piston to expel the exhaust from the combustion chamber, but aid in the pistons upward travel. The combined effect can increase horsepower, torque, and throttle response as well as decrease turbo lag and spool times.

Flowducer FAQ

I have heard that compressed air in an exhaust system can cause cracks or breaking because of the rapid temperature change. Does this apply to a flowducer?

No. Compressed CO2 introduced at a turbocharger would have negative effects. This is not what the flowducer does. Typically, flowducers are placed in the exhaust near the rear of the car. (18" from the end of the exhaust tip is ideal. Between 10" and 24" is recommended.)

How much horsepower can I expect to gain from the flowducer?

This is totally dependant upon the shape, size, length, and efficiency of your exhaust system. We have seen gains of as little as 5 horsepower to the wheels and as much as 38 horsepower from the flowducer alone! This doesn't even include the gain you will see from our other systems, such as, the Interfreezer.

Does it work with turbochargers as well as non-turbo cars?

Yes. Flowducers works on just about any application.

Is the flowducer hard to install?

No. Although, in most cases some welding is required. This is a very easy task for an experienced shop. If you're a 'do-it-yourselfer', the welding portion is the only part of the Cryofuzion install we recommend having professionally done. Most times, a small hole is cut in the exhaust pipe, the flowducer is installed, and a small bead of weld is placed around the stainless steel flange.

Why would I want to cool my exhaust?

You wouldn't. There's no practical use for cooling spent exhaust gases. The cooling is a side effect of releasing a compressed gas. The temperature of the exhaust 1 foot from the back of the car doesn't in any way effect performance.

Are flowducers available separately?

Yes. Every component in the Cryofuzion family available separately. Also, our flowducer kits are now available separately as well. For specials, click here.

How do I decide where they should be installed on my car? Although flowducers can be installed on just about any exhaust, they should never be installed before a chambered muffler. (Flowmaster, some Dynomax, etc.) The absolute best placement is after all mufflers and resonators about 18" from the end of the exhaust tip. On many vehicles, this right in the middle of the muffler. If this is the case, it is best to place the flowducer right in front of the muffler. If your car has either a chambered muffler or a cross flowing muffler (Acura NSX, Toyota MR2, Camero, etc.) it is best to place the flowducers immediately after the muffler.
How do I know what size to order? Flowducer sizes are based on the diameter of the exhaust pipe and number of exhaust outlets. Exhaust tip size is irrelevant. (It's more in how you use it.)

"The ultimate cold air intake."

The Interfreezer™ is basically a heat exchanger. Is is an aluminum chamber, through which the air flows as it enters the engine. After passing through the air filter, the air enters the motor via the air intake pipe or intercooler tubing. It is at this point that we cool the incoming air by passing it through a series of long, thin walled tubes within the Interfreezer™. These tubes are surrounded and cooled by the pressurized CO₂ which enters the Interfreezer™ at a temperature as low as 100 degrees below zero. This extreme cooling effect not only cools the air, thereby creating more horsepower, but it also dries it. Moisture is removed from the air as it enters the motor, which, in turn increases burn rate.

The cooling effect of the Interfreezer™ is so dramatic that after only seconds you will actually see ice crystallizing on the outside of the intake pipe.

After entering the Interfreezer™, the CO₂ is still full of energy which can be further utilized to create horsepower and dominate the competition. Because the CO₂ never mixes with the air used by the engine, there is still residual compressed gas which can be used in other areas of the car. That means not only is using an Interfreezer™ completely safe, but efficient. Add other Cryofuzion accessories to optimize the horsepower unleashed when you hit the button!

The table below will help you select an Interfreezer option that is right for you. The Interfreezer is the basis for most of the Cryofuzion kits available now. Although all kits are available separately, start with the Interfreezer when planning a Cryofuzion system.

Interfreezer	HP Capacity	Tube sizes	Outside Dia.	Core Lengths	Overall Lengths	# of .5" tubes	equiv. tube dia.
Street	350	2.25", 2.5",2.75, 3"	3.5"	3.75", 6.25", 8.5"	7.75", 10.25", 12.5"	19	2.2"
Pro	800	2.5, 3", 3.5"	4.5"	10", 12"	17", 19"	55	3.7"
Race	2500	3", 3.5", 4"	6.5"	10", 12"	17", 19"	85	4.6"
Custom	Any	Any	Any	Any	Any	Any	Any

HP Capacity = the recommended maximum engine horsepower output for the application.

Tube sizes = These are the sizes of "end bells" available to fit in line with your intercooler or intake piping.

Outside dia. = The outer diameter of the Interfreezer shell.

Core Length = The length of the interfreezer core

Overall Length = The length of the interfreezer with the "end bells" installed

# of .5" tubes = Each interfreezer uses .5" tubing through which the intake air flows. The more tubes, the more airflow capacity.

Equivalent tube diameter = The equivalent section of tubing compared to the combination of all of the tubes within the interfreezer.

It is said the race is won in the first 5 feet of the track. Cryofuzion™ puts you in the lead in more ways than one. The only clue from the outside of the vehicle that a Cryofuzion™ system may be in use is perhaps the most devious gadget ever used by racers with the drive to win. Dubbed cheetah jets, this system actually uses CO₂ to slow down your opponent!

Click on an image above for a larger photo.

How? A simple solution. CO₂ displaces oxygen. When released anywhere near the air inlet of a car, it will displace the oxygen being drawn in by the air intake, thereby slowing the car down. This is why it is important to get the leftover CO₂ as far away from the engine compartment of your car as possible. And, what better place to put it than under the hood of the car you're racing? Cheetah Jets are a system of nozzles that expel the CO₂ out and away from the sides of the car with a Cryofuzion™ system. With a range of up to 20 feet, the CO₂ is then ingested into the intake of the unsuspecting racer beside you. You've got the holeshot... you win the race!
