actually i haven't decided yet, that's why i haven't got that stuff on order... intake manifold ill be getting magnus motorsports.

the rest is yet to be revealed

 

how much whp gain are we talking about here on stock turbo & stock ic

 

Its garbage.

If it does make power, it's because your ingesting the nitrous, and thus running lean, or its actually working, making the intake charge denser, and again making you run lean.

Not to mention your pissing away very expensive nitrous.

 

Actually, I've seen a few people that use the sprayer and have seen anywhere from a 20 to 50 whp gain. I found this dyno chart of a before/after IC sprayer. They did use nitrous to spray theirs but CO2 would have pretty much the same affect and be WAY cheaper to refill. Yes, it would depend on your supporting mods as to how much you would gain but...it still appears to work.

 

How would it not work??? Your getting cooler intake temps resulting in more power. Co2 gets way colder than water. Use both even. Ive seen cars dynod and it helps out especially if its hot outside

 

FYI, you have no idea what your talking about. Use the search option and find all the posts I have made regarding using nitrous on my evo with success.

on a 45 shot and racegas, I went 11.52 @ 119, on 80 shot I ran 11.500 @ 116 with a slipping clutch (but 96mph at the 1/8..so it shoulda been 122-123mph).

Iv run 4 bottles of nitrous through the evo with 0 problems. I ran a 40shot on pumpgas a few weeks ago with the stock turbo and although I had traction problems and the ET was very poor, I did run 117mph on pumpgas with the 40shot and 20psi.

The nitrous kit works so well, that I took the BR440 turbokit off the car and will just make that 40hp back with a larger nitrous shot when I go to the track.

Once I get a fresh clutch in the car that will hold the torque, I will run as high as 125hp worth of nitrous. I expect the car to run high 10's @ 125+mph on the stock turbo with that nitrous hit. On stock pistons/rods.

 

I find that dyno graph highly debatable. That gain in power is NOT coming from the air temp change. The engine woudn't even be on boost at 2700rpm and the graph is already showing a 20+hp differance. the intercooler shoudn't even be up a few degree's in temp over ambient at this point in the pull. Id bet all that gain is from the nitrous going right through the IC and FMIC and getting sucked up into the intake pipe.

Every car I have seen show some power gain from an IC nos sprayer, was ingesting some nitrous oxide through the airfilter. When you put CO2 in the bottle, the car missfires and pops and makes poor power. The co2 chokes.

I will tell everyone who will listen that the IC sprayer is a complete waste of time.
Cars come into my shop with it, I give the owners hell for buying into such bullcrap. The same parts as an IC sprayer are a normal nitrous kit. Just spray the nitrous into the engine and don't waste it.

 

Total waste of money!!! A 30-50 shot will cool the intake charge and add real HP...spraying Co2 or N20 on the outside of the intercooler is a waste.

HP is HP and a stock motor will handle a 50 shot just fine. I know people spraying a 125 shot on built engines while pushing 550AWHP on boost alone on 1g dsms.

It is not a waste of money, depending on application. For almost all street driven Evo's it has questionable value since most owners do not drive their cars hard enough or long enough for the benefits to come into play.

I open road race, up to 54 minutes of WOT, never dropping below 6,500 rpm. You will experience heat soak under those conditions, no matter whose intercooler you are running. A intercooler sprayer using Co2 does a great job of controlling heat soak, a 10 second burst every 5 to 10 miles at 160 mph makes a huge difference. I get about 12 such blasts out of a 5 lb bottle.

So you can't say it is a worthless addition. It all depends on application. Notrous would be worthless for me, because of application

Hit the wrong key on a word in my last post. NITROUS is spelled thusly.

Show me IAT1 and IAT2 logs of that because unless your IC is undersized for the application or your running in AZ or similiar climate I don't see it happening.

 

Would a 50 shot of nitrous increase cylinder pressures more than 50hp worth of boost?

 

you are correct. it has been independently tested many times before and that was the results. i remember when david buschur wrote about this and he found that there was no gain in using just co2, but he did find an hp gain with spraying nitrous on the intercooler because it was ingested by the intake. basically giving you a small shot of nitrous.

 

Hi there

I dont know if any of you who say it is worth nothing ever experianced the same car at an ambient temperature of 32°C and -12°C...
You drive a completely different car!
Especially, if you have a big turbo, you will face a dramatic increase of power...and even more important, spool-up will be much more aggressive. This will make the car much quicker out of curves, and faster over all. The reason herefor is the higher density of the air, which also helps at zero boost or low boost.
If you want more torque, you will have more cylinder pressure doing it with NOS, more boost, Aquamist, bigger IC...whatever.
But the point is, that you will face the problem of knocking and detonation - and therefor extrem high load - MUCH later at lower intake temperature.

 

Water/Alky/Methanol injection seems to be a MUCH MUCH MUCH more effect way to decrease your intake temps... as well as many other additional beneficial effects to them.
