Freezing intake pipe

[JoshCrane1]

Thinking about freezing my intake pipe on my tc with liquid nitrogen, but not the filter, n2 dont combust at all. How do you think lowering my intake pipe to -320 will effect my performance? thinking about trying it at the track. Unusual job with excess ln2 been trying to do something with it fun.

energy(heat) needs time to transfer. especially to a good insulator like air.

At the speed that the air is rushing and the minimal volume to contact area the temperature of the air getting into the engine will only lower by a few degrees.

Now if you were to place something designed like a radiator where the volume to contact area were smaller then you may have a significant effect. The only problem with that is that it will cause restriction and turbulance.

A frozen intake pipe would work great for 1/4mile passes. A lot of people have tried it.

And heat does need time to transfer, but he's N/A so there isn't that much heat in the air he's taking in. Plus 95* air passing through a -320* metal tunnel will change temps pretty quick. Same effect as an intercooler chiller kit.

If you've got the N2, play with it. I know I would. :coolp:

thanks for the help guys i will let yall know what happens

It'll help a little but don't expect huge performance boosts from it.

Crazy idea. I love it! My ratt rod bug could use a set up like that. I could raise my boost, and advance my timing more if the incoming air was cooler.

What if you made a box out of tin to surround the intake filter. A box in a box would be great if you had the room. That way you could freeze in between the two and the condensation that will form from the extreme cold in the hot environment, could drain out, and not get sucked in the intake.

I've been tossing the idea around with using alcohol and a cold start injector, and spray it in the intake plenum.

This sounds similar to how the CryO2 system works. You "splice" the 3-4 inch CryO2 pipe in your intake piping. The CryO2 pipe has a piece "floating" in the center of it that looks like an ice cream cone with the ice cream end facing the filter and the point of the cone facing the engine. You hook up a CO2 bottle to it. When you press the button, it sends the CO2 through the intake unit and uses the CO2 to supercool the ice cream cone. When air passes over the cone, it gets cooled down and gives you a colder air charge. Almost bought one a few months back but it got sold out from under me.

That sounds cool, no pun intended lol, Do you have more info on that?

My bug is all wrong, but a ton of fun. I pull through the carburetor, into the turbo, so its like super heating the air/fuel. Low 12's in the 1/4 mile and street leagal.

Great topic. :bow: Has me thinking again.

The intake piece is only one of 3 pieces you can get for the system. You can also add pieces that cool your fuel rail as well as spray cold CO2 on your intercooler.

By the way, that is a sweet ass bug Rob. I thought about doing a draw through turbo setup on one of my first gen RX-7's but it was tough to find a manifold for that type of setup. Looks mean man :up:

That bug is wicked.

Ive looked at the cryo setups before on previous cars. Not a bad system.

Now THAT's a bug!

I want!
