Question IAT cooling using n2o and FI. hi gang, i posted this in the N2O area but no responses, so i'll try here:
i have a s/c c5, i/c magnacharger. during the hot and humid times here in tx the power drops down quite abit. now im happy with the current power levels, 475h/465t but dont want to loose the 25-40h because of the temps, would like to use n2o to cool the intake air. thought about alky, meth, etc., but already have a complete kit avail.
Positives?
Negatives?
i have a NOS wet kit that i removed from my daughters ride and would like to use this for a dry intake air cooling setup. we have the gauge, htr, pretty much everythhing but a FPSS, (not sure if its actually needed)
im also looking for the power levels for the following jets to be used as dry only, and does it matter that im already pushing 7lbs of boost does it multiply with boost?
NOS jets:
18=
22=
24=
26=
30=
36=
Again, not really looking to increase power level, just want to keep it consistant in the heat and humidity.
any and all suggestion would be greatly appreciated.
thanks in advance,
dan

One way or the other, you are going to be adding power to the car to fight the loss that is caused by hotter ambient temps. A 15-20 degree temp change can easily cost you .3-.5s of ET at the track for any FI car. We simply can't get the same amount of compressed air to the motor on a hot day.
Spraying nitrous means power on hot or cold days. More air in the FI charge means more power from a give set of jets. Assume 75% more power above any advertised spray settings when used with FI. You may actually get more than that in some cases though.
Meth/Water or Meth will provide intake charge cooling and fuel which can then be taken advantage of to run more timing for power. The additional power will mask the loss you see today with bad temps.
I'd personally pulley up to 9lbs and go with a meth kit to address the fuel and cooling issues.

I'd look at using a Meth kti for what you are after. N20 is more used for making more power or spinning up the motor quicker.
The Meth kit's are designed for exactly your situation. It act's like an intercooler.

doesnt the puter see the cooler temps from the maf being sprayed by either n20, meth, etc (small shot), and then the puter will increase/compensate the fuel output to the injectors.
yes, newbie questions. so please dont beat me up too much..

A couple of things...The Magnacharger leaves you no good option to spray. Spraying into the intake, through the S/C exposes your rotors and housing to N2O, an oxidizer of aluminum. Piping it into the base has you spraying through the intercooler which I was told is no good either. Puddling is a problem.
Next, it's been done by a few guys. One guy did a 35 shot and only showed 15 at the wheels on the dyno. Another did a 50 and said it was ok. Yet another did 75 and loved it and one guy made the mistake of winging it and put a 125 shot. He said it ran AWESOME for 6 shots, then the tranny blew up, which probably saved his engine as he was running a dry shot and was clueless.
I bought a LS1 Cold Fusion kit with every plan to spray through my Radix. After much research I have (This week) sold my N2O kit.
Seemed like too much possibility for bad issues and little gain.
I am getting a meth kit. Octane plus cooling properties.
Good luck with your choice

Definitley do the meth kit. It's cheaper to refill also.(at least here in Detroit) The meth is designed for what you need like stated above. Unlike N2O you'll have to worry about running to rich instead of running to lean, which is better. If you run to rich just make sure to check the plugs, fuel in the oil, and keeping clean oil to prevent wash out. With N2O you have to worry about not getting enough fuel, which leads to more damaging effects, which im sure most of us know about. Im not sure about meth through a magna so I can't comment about that. Like 2001-WS6 said, I would go to a 9lb pulley and spray meth, and watch those intake temps drop..

i think n2o and FI go very well together, esp on a turbo setup! it will cool the intake (wich is where you get the 'added' power from ontop of the n2o power) and spool the turbo faster! also you dont need a huge shot. Someof the Evo guys run about a 25 hit so i recon a 50 shot would be more than enough! also its less damaging as an antilag device (you spray when you go WOT and then it turns of when you sart making reasonable boost) than proper antilag.

On a 4 cyl. that would work better. With an 8 cyl. being able to make the power that it can especially with FI a stall will net safer, cheaper, and more reliable ways to launch or spool the turbo. His setup is totally different from a turbo setup. For what he want's N20 wouldn't be his best bet it wouldn't be the best setup for his application. (going off his post of course).. Especially with what involved to spray through the blower like stated above. That's JMO.
I've never seen meth/alky ruin any type of metals, but I would be curious on how it would react spraying it through the magna.
