Cooling intake w/nitrous

[Nick-G]

I'm just curious has anyone here ever tried using a nitrous kit like this to cool their intake temps? Does anyone here think it would work good enough to be worth trying?

I'm really not a nitrous person but i'm just wondering if I installed the first kit on an intercooler with my turbo setup then possibly the second one right before the tb if it would actually give me any gains?

I once knew someone from the East Coast who had the Magnacharger on his 99 Grand Am with a small (I think 35 or so) shot of dry nitrous....this was before the time of headers and other good stuff. He just had a single fogger nozzle tapped into the elbow between the SC outlet and the UIM. He did use drag radials though.....ran mid 13's at about a buck-seven.

alot of guys run a 35 shot nitrous and it cools chargers and cools the intake.. Its cold so it will help lower intake temps and you will also get the benifit of the nitrous as well..

I'm not actually looking to spray any nitrous into my engine at all i'm just wondering if I could use it with the items I linked to above to help keep intake temps down.

I would say it wouldn't be worth it. you don't want to spray NO2 anywhere but in your intake. it works on a intercooler with boost because the compressed air is much hotter then ambient air temp. it would not really result in much if any gains.

The CO2 thing i think would be more of a restriction in the intake then its worth... Yeah it might cool the intake temps a little but it also has a big block in the air flow.... you will probibly not make up for the loss in volume with the decrease in temps.

N2O, C02 spraying on the IC is a good idea for racing. But using Meth/watter is better but injested. No high pressure bottles to refill. Much cheaper to maintain. Go to local store to fill up. Use all day.

If it's not going in the engine why would you want to use NO2? Co2 I think is cheaper and has a lower boiling point temp.


No2 -11.2 C Co2 -78.5 C

hey i was thinking about this too! but with a twist lol

ok you know how certain like 94-95 cars i think it is have coolant passages on the throttle body that arent hooked up? well what if you ran co2 through those lines and froze the throttle body? i dont see any reason why this wouldnt work and since its connected to the intake manifold it'll cool that too! thats assuming you have phenolic spacers which i do i was just thinking of going the next step further since my intake still gets hot with the phenolic spacers.

Actually those lines ran through the TB to keep the TB from freezing and sticking open in cold climates. I know in the import world they also have loops in front of their IC to spray CO2 over the IC to improve the efficiency of the IC itself. I agree with Shane about the 35 shot. It's small, would hardly use any N2O, and is going to give a good cooling effect to your intake charge. That is part of how N2O works. 1. it cools the intake charge, 2. it injects more oxygen into your engine. I know a long while back when I was a noob I had the idea to run A/C lines in my air cleaner box to cool the intake charge. N/A it wouldn't do a whole lot, and the extra power it did create would probably be soaked back up (if not more power needed) to run the A/C compressor. I know some of the Ford Lightnings did it, but then again, those are FAI, not NA

anything that will lower iats is worth it. but is it worth it to your pocket book is the question. honestly spray a 35 shot like suggested to cool the iats and gain some from the n2o

yeah i totally forgot about freezing the butterfly! lol i guess that wouldnt work or would it? someone needs to try it!

i've also been trying to think of a way to cool the egr gasses without deleting the egr since that right there would produce more heat. maybe like on those cryo kits how they have the inline fuel bar that freezes the fuel well what if there was an inline cooler on the egr line coming off the exhaust manifolds?

the thing is i have the phenolic spacers seperating the upper intake from the rest of the engine and i have a 95 without the coolant lines on the throttle body but the egr still heats my upper intake! i want a true cold air intake charge i also have a 3.5" real aluminum piping going into the fender well. when i put my hand on the intake piping its ice cold but not the manifold. im aware i cant make it 100% cold but the egr heat is making my spacers and everything else pretty much useless.

Just delete the egr all together.

Also about running a 35 shot would I run into any problems with that? I am going to be running a turbo with a lot of boost so I'm wondering would I run into any problems with running n20 with a turbo?

[kwhauck]

i don't see why you would, i plan on running at least a 50 shot with my supercharger, probably will be more like 100.......or 35, then 50 in two stages.....

ok so how do i go about deleting the egr if my cars a 95 with obd 1.5? 3400 swap by the way but using the 3100 stuff.

Block off plate. so it still functions but is not feeding the gasses back to the engine.. this is the easiest way.. that also will not trip a code.

keep in mind that nitrous is flamable... so if you don't spray into the engine you want to make sure its not getting near anything that could ignite it... spraying a small shot into the engine is the easiest/safest way to cool the intake.

If you don't want to run NO2 then the next best option is a Water/Meth kit like what was mentioned above.. it cools everything and allows you to run more timing and again is VERY cheap to refill.... Its just windshield washer fluid...
