Compressed Air Supercharger

Very freekin' cool! Thanks.

Interesting. Might as well design a car self air compressing system, so that you wont have to charge the tank externally by a compressor.

That's the whole idea is that it is not parasitic to the performance of the vehicle like turbo and supercharging....and that the cylinder burn is unaffected like nitros...

I designed that around 30 years ago. Never made it to market. My idea was to have a compressor charging a bottle and when boost was needed a dividing butterfly flap would change and let the higher compressed air in. If you look at it as a short boost (based on a normal carburetor of around 650 CFM) of around 14 seconds (quarter mile) then it does not take that large of an air bottle.

Like it said in the video, a lot of people have had this idea, and it can be easily drawn on paper, but none have actually done the final work. It took them many years to get to this point and I'm sure there was a bunch of $$$ to do it.

An air cylinder approx 4 inch x 3/4 inch, to slacken and tighten the V drive belt off the engine.

This is cool!

Lots of hard work went into this, back in the early 60's a racer (Ohio George Montgomery) was working on a compressed air induction system. I saw a write up in Hot Rod Mag. on it, the exhaust note had the sound of a shotgun. I tried to follow the feat but there was little available after the initial article.

There is a dragster in Don Garlits Museum that has a huge tank 4 compressed air. Instead of a blower on the motor.

Found this....

..."Back in the early 60's Garrett (that turned in to Allied then AlliedSignal then Honeywell) made this turbine powered dragster powered by 3 35 pound partially-aluminum turbine engines. All powered off of compressed air and fuel mixture.

Each turbine is rated at 750 foot-pounds of torque capable of 70,000rpm.
In the quarter mile it ran 8.75 at 161mph .
This Dragster made it in many published articles like October 1962 edition of Hot Rod."...

Any idea what a system costs? I couldn't find any info.

It looks like the systems are going to be sold through dealerships, which they are still acquiring....so no.....The support system for filling the tanks at the track in rapid succession they est in the video at ~$7k....but you could probably put one together for a few grand with used equipment....A lot easier if you have a buddy with a dive shop that fills air tanks....I would go for the carbon fiber tanks....

About 10 of these...haha $80 a pop

So. Maybe $15K for the set-up.

I guess if you're really are in to drag racing......................

You could mitigate cost by filling dive tanks on the side....$5 a pop.....

• $8,200.00
• And these don't like anything but super clean air.

There's a clue to price in the name.....'supercharger'

....and you are right about clean air....which didn't seem to get mentioned in the video.

Roots type superchargers are positive displacement air compressors. Think of them as a very long stretched gears. Consequently, they are designed and built with extremely close tolerances.

Dirt is not their friend.

Centrifugal blowers and this system would tolerate more grit before failing. (All of my experience is with centrifugal blowers, so some of this is speculation)

I think back on an ill conceived experiment utilizing NO2 and an intercooled Dodge 4 cylinder. Never did find the turbo intake fan...

Seems that controlling these sorts of things has only recently become possible due to a computers ability to quickly and accurately control the air \ fuel mixture. otherwise things go boom or melt and sometimes both.

This is clearly for 1/4 mile races only. The draw-backs mentioned for nitrous-oxide and liquid oxygen can be avoided by careful metering. The benefits of nitrous-oxide and liquid oxygen, is that it can be either a continuous boost or a temporary boost, and still allow the car to run with empty tanks. A temporary boost means that it can be programed to only kick in when needed, not during deceleration, idling or even during moderate accelerations. And best of all, it can be used for street machines or Nascar racers. !/4 mile racers is a very limited application.

I doubt we'll ever see NOx on a NASCAR engine. They run for 3-4 hours at up to 8,500 RPM. Nitrous is not conducive to long engine life.

The present engines produce far more horsepower than can be applied to the ground at anything under 120MPH already. These engines have to last over 600 miles in some cases.

I like my engines to last at least 200,000 miles . . . .

Obviously a drag racing device, as the stored air would run out quickly in an oval or road course track. A bit like nitrous isn't it?

Ram air effect without needing speed to get the extra air jammed into the cylinders.

Now if you want to have some real fun, try using compressed oxygen instead of air. Just might take some very special pistons and cylinders, but, hey, could be quite interesting, but probably not for long.
