NITROUS OXIDE ( nos / n2o ) advice forum

Ive been reading recently about various air cooling methods using carbon dioxide, I know won do intercooler sprays etc... but has anyone ever seen these before?



Its a bung that site in the air intake and CO2 passes through it and the air that passes over it is cooled. Good idea but would have thought it would be a little restrictive.

I was thinking about a pipe wrapped round you intake pipes (like a spring) and pass CO2 through the pipe, as its in contact with your intake pipes it should cool it quite well....any thoughts?

Any plans to produce anything along the same lines trev?

As you say ,restrictive, would think that the disadvantage outweighs the advantage, l thought about wraping brake pipe around the intercooler hose, and running co2 through it,on a cosworth one of those things l never got round to.

I don't want to say for sure that the product is restrictive enough to reduce performance without self testing but it sure looks like it. This product has been posted in the past but I have learned not to be sure if I am not sure with no hands on experience.

The air moves so fast at WOT that just cooling the outer intake pipe would have limited performance for the idea you suggest. An intercooler spray kit works as you cover a much bigger area, but most intake pipes are very short and only the outer air would come in contact with the pipe wall.

Water injection would probably be the best best if you require cooling off nitrous.

I reckon you could make a spiral of copper pipe and put this inside an over sized piece of inlet. I used this on a still once - erm used to crack certain hydrocarbons

I'd bet good money that it would be restrictive and not very effective as there is so little contact area and the airflow will be so fast that it has little time to achieve any heat exchange.

However (as you may have guessed) I do have a much better design that we're working on that WILL work and does not suffer from the limitations described above.
It isn't a sleeve on the outside, it isn't a spiral of copper pipe (although we have tried that) but it's not easy to make and as a consequence may be a while before we have it in production.

Yeah - I agree anything with a round cross section is going to be useless due to the surface area to volume being minimised (Damn Euclidean geometry!)
This is almost certainly a stupid question but..... has anyone ever tried cooling the fuel? I think petrol remains combustible down to -70c (ish) so you could probably absorb a fair bit of heat by injecting chilled petrol?

http://www.flex-a-lite.com/auto/html/fuel-coolers.html Been on the market for a while, dont know how effective it would be, l would think that this would need to be fitted behind the front grill,l would be a bit concerned about safety issues if a front end collision occured.

Yep coolers been on the market for years.

Take a look at my combined fuel and nitrous distribution block design and you should realise a UNIQUE feature they have over all others.

Good point Trev. One day I'll come up with an idea that nobody else has

Ant says the same thing, so I'll give you the same answer "not if I can help it" - LOL

I have a big advantage over most people, my brain seldom stops inventing even while I'm asleep, plus I started at 15 years old so that's almost 40 years of back log that I have in store.

Believe it or not I invented EVERY part (including engine parts) for a revolutionary motorcycle when I was just 15 years old and to this day many of the parts have not been invented by anyone else. A good number of parts have been invented by others over the past 35 + years which proves that my ideas were good - just a shame I don't have the time to get them all into production!!!

Time to send the forms into the Patent Office

If only!!!
However the fact is that by applying for a patent you have to disclose all the tech info, so that someone elsewhere in the world can rip it off. On top of that each one can cost many £1,000s to obtain and there wouldn't be much point if I never get round to making any of them, so they'll just have to stay on the back burner till I either get time or die!!!!
