Boost

[milesguy81]

So hear me out... I had this idea when I was cleaning the turbo on my dads truck and I was like "Hey turbos just blast more air into the engine, what if you did it with compressed air??" I know it wouldn't last long at all but maybe if you filled like a 1 gallon tank up to like 150psi then put on one of those regulator things to get it down to like 3-5 you could have a blast of boost for a few seconds! Probably a dumb idea but since I have like all the stuff I should just try it. The intake manifold I have came with a little thing to hook up maybe a turbo hose, NoS hose, compressed air hose... I wanted to make sure I wouldnt turn my buggy into a bomb first though haha

You mean nitrous oxide or nos witch is compressed nitrogen and because nitrogen is cold it can be condensed a lot more than Normal air

Also I would put it in front of the carburetor most people put it in the intake tube but it think it would work better with it in front also they make tiny nitrous kits https://www.amazon.com/Predator-Per...xt&ref_=fplfs&psc=1&smid=A34ZGLX2KUBO21&gQT=1

Ya Ive seen those... I meant hooking up a tank of compressed air to it

When adding more air, you need to add an appropriate amount of fuel. Not that easy to do on a gravity fed engine. I think with the nitrous kits they fatten up the jet a bit. Having it running very rich.

Here's a dragster that runs on compressed air:

This is what you are trying to do.

Yep cobra thats pretty much what I want to do. I have an old mikuni fuel pump from a lawn tractor, and for regulating pressure I was thinking a regulator from an old air compressor I have then something like this to get it accurate under 10 psi.

Nope. Adds oxygen so more fuel can be added and stoic be maintained. Why full throttle on Nitrous vehicles adds fuel with the fogger.

 

[John Roger]

Nitrous has an oxygen N2O like google it

 

[John Roger]

Also if nitrogen is cold then the nitrogen is more dense ex why you make slightly more power when it is colder then when it is hotter the air is more dense hence more oxygen to burn that is what boost it if there is more pressure it more dense hence more oxygen to burn that whips most of the time cars that make more psi of boost make more Hp compressed CO2 would not work because the engine can burn the oxygen of the carbon also if you where going to use CO2 to make boost would It not be better than to pump the exhaust into the intake

 

[johndeerebones]

Cold i get. No co2 won't work because the byproduct would be carbon stopping up the engine. Also on a molecular level, Carbon co2 has a stronger bond than nitrogen n2o. Nitrogen is dry and passes through an engine without harm. Yes stands to reason cold is able to pack more o2 into the cylinder. Why intercoolers improve the power under boost. Also why methanol injection systems on super stock diesels are often iced.

That’s what I am saying But you went more into detail
