OK, this is going to seem kinda crazy, but I think it'll work and inexpensively. Bare with me. Don't go stealing what could be a million dollar idea. © LOL, ;D
This weekend when I was working on my car and saw my potato gun sitting in the corner of the garage and it brought back memories. I used to make them as a hobby. And where this is going is I used to make pneumatic ones as well which would allow you compress air into a chamber (up to 100 psi safely), load your projectile and quickly open a ball valve to send almost any object out the barrel flying 100+ yrds. All you needed was source of compressed air like a $20 tire inflator.
That got me thinking. I wonder if anyone has tried to produce inexpensive boost to their engine using a metered boost of compressed / stored air? I've seen the leaf blower "turbos", but I think this would actually work with real results.
Attached is a picture of some quick plans. Pictures are worth 1000 words.
Could this theoretically work for lets say just a 1/4 miles worth of boost. I'm sure I could figure out how much volume at
psi to produce 6-17 lbs of boost for 15+ seconds. My only concern would be chocking the engine. I'm guessing you could store enough air, for the engine to breath, to get it up to the line and a quarter miles time worth. Perhaps there would even need to be some sort of blow off valve.
I was talking with my neighbor about this, whom has a built mustang, and he said he could make a circuit board to regulate the psi going into the engine at different rpms as not to be producing excessive boost while idling.
Coolest thing of all is the fact you can refill the chambers with a cheap electric cigarette lighter pump or even stop by the gas station if on the road.
The cylinders that hold the air would be best in the trunk or bed of a truck.
And it wouldn't weight too much.
What do you guys think?
The only thing I can't figure out is how quickly the pressure will drop before it's not producing any boost at all. Just a quick figure. Let's say I have (6) 4"x 36" compression chambers that I could pressurize to 85-100 psi safely. During a quart mile run, how quickly would the pressure drop if I'm regulating the air to 7 psi of boost for up to 10-17 seconds. I'm thinking staging time and quarter mile time combined.
Also, these plans would have a blow through carb hat so it'll hold a constant 7 psi of boost. Extra fuel would be feed with a nos plate but only feeding the extra fuel needed.
This idea seems cool to me cause I could remove box that has the chambers inclosed (think subwoofer box size) and I could easily compress air into the chambers using a cigarette lighter compressor.
Another thing I had though of was building the compression chambers into a cooler so I could Ice them down making the charged air cooled. That and my it could keep my beer cold too. LOL. Seriously though. I'm looking at $100 in materials for something that could possibly be a cheap source of boost for racing. The best of both NOS and turbo / supercharging. No spool up time and I can remove the unit when I want.
Here's a carb hat that'll hold compression.
