i was just having a chat about f1's and racing and thought would it be possible to use liquid nitrogen to cool a engine with it having some sort of restrictive coating in the engine or some sort. So that it doesnt cool the metal enough to shatter.

little bit of common sense required here

liquid LPG injection systems are available these days- as the LPG is port injected, it changes from a liquid to a vapour, and the change of state of the liquid to a low pressure gas results in a drop in temperature. this also sucks heat out of the combined intake charge in the inlet manifold (latent heat of evaporation). it turns into gas instantly

same would happen with liquid nitrogen. but it wouldn't benefit power, because nitrogen isn't combustible and would merely take up space that could be occupied by oxygen

the reason NOS gives a power increase is because its N20, and during combustion the oxygen molecules are stripped off the compound to massively aid the combustion of the incoming fuel/air charge

sorry if the original post has come across wrong, but i was asking if it could be used to cool the engine not used as a fuel. When i mentioned f1's its purely because they dont have radiators and was thinking if this could be a substitute in any vehicle

who told you F1 cars don't have radiators?

as Mikey Mike said- they do (1 in each sidepod), and they cost ~$50k each

methanol drag cars don't usually have radiators, because the fuel burns very cold, and the cars are only usually running for a short amount of time (not long enough for heat soak to become a problem)

well lets say they some how managed to fill all the cooling channels with liquid nitrogen, as the engine would heat up a extreme amount of pressure would be exerted to the internals of the engine by the liquid nitrogen trying to become a gas = catastrophic failure = very bad.

the only way it could be implemented is by spraying it in a liquid form in front of the radiators and as it becomes a gas will cool the radiators.

and then there are the safety issues for having that much liquid nitrogen on the track, freezing drivers and the anesthetic effect of nitrogen and the chance of a explosion due to the liquid nitrogen heating up

and then the engineering complications. how are you going 2 pump it what will keep the spray tips from freezing, un even cooling will cause the radiator to crack what if a pipe caring liquid nitrogen broke there would need to be a emergency shut of capable of operating in extreme cold, how to store enough liquid nitrogen and how to keep the insulated vessel crash proof

and the added weight would slow the car down making any cooling benefits negligible

i saw a setup in i think it was an off tits turbo vs commodore a few years ago that had a massive esky in the boot filled with liquid nitrogen and the coolant was passed through a heat exchange in the box to cool it down

If you had liquid nitrogen in your engine and it was still a liquid.. im pretty sure your oil would be frozen, since it has a freezing point somewhere around 0 °C , and the liquid nitrogens boiling boint is something like -195 °C, probably would freeze your fuel aswell ;)

I've been looking at water/methanol injection to keep my intake and internal engine temps down :P

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
