Im curious if any of you have used any if these things b4. here are our options from what i have seen.

first you can have a water/meth injection which im not sure how it works but im sure one of you do.

second you can have a co2 fmic sprayer its pretty simple how thease work but couldent you suck some co2 into your engine if you have a cold air intake?

third you could have a no2 fmic sprayer basicley the same as the co2 but sucking a lil no2 in the air intake couldent hurt.

last you could put an efi no2 fogger post mass air censor or pre fmic it would keep it cold and ad a lil no2 with out any of that retarded direct shot bs

what kind of hp gains could we c from this im curious what is the best way to go?

 

The intercooler sprayers just cool down the intake, whether co2 or spray.

Spraying nitrous post maf is a bad idea as you aren't metering any air change which is really what nitrous does. Bottom line on this motor with direct injection nitrous isn't a good idea. The intercooler sprayer works fine, you wont ingest any into your motor, you'll just cool off the intercooler and better cool the air.

 

so if your driving with it floored and you spray your fmic will it give you a boost of hp because of the cold air? .what if you sprayed no2 pre maf, or post turbo pre intercooler?

 

You could spray the nitrous pre maf and it might work, a 30 shot or something. I don't know how the temperamental the maf is though. Until we have better control of software I wouldn't pull the trigger on anything. When we start boosting these cars we'll spray some water meth and make some power.

Basically spraying nitrous on the intercooler cools down the surface and promotes heat transfer away from the hot air. It doesn't physically enter your motor that way.

 

yeah this is all speculation till we get a good ecu tuning software like the accessport .. hint hint Alta and if i were to ever put not in my car it would be a fogger that sprays a small amount of no2 that just cools the air and ups the o2 value in it not like a 30 direct port shot that is just dumb

 

I don't understand what you're saying? A 30 shot is just nitrous jetted to gain you around 30hp sprayed pre maf. You could spray it on the intercooler and chill stuff down, spraying into the motor isn't the best idea in the world without a lot of extras, wot switch, etc.

 

I mean that i would never put a direct port shot in my car. then i mean if you spray the intercooler when you are going full speed will it give you a gain in hp from the cold air?

 

Direct port is a different form of nitrous- it means you inject it into each of the intake manifold primaries. A dry shot is spraying nitrous without fuel somewhere in the intake tract. And shooting nitrous on the intercooler, which is very different, will cool it down. Don't think of it as gaining horsepower, but preventing a loss of horsepower due to heatsoak (your intercooler getting really hot and becoming inefficient). You could probably gain 5-10hp after the small stock IC is heatsoaked, or just buy a larger intercooler like the one from Alta and get a similar gain.

 

im not really consigering nos im just curious about it. what about water meth?

 

When we can raise the boost and timing I'm all for it. Stock, not yet. You can basically run race gas timing on pump gas with the right water meth setup. Car really wakes up, I can only imagine the direct injection with all that boost and timing. Can't wait!

 

no kidding

 

I don't know about the R56 but in my R53 I spray the intercooler with nitrous and gain a little more than 5-10hp

 

would it be the same with co2 as it is near the same temp

 

Yes as long as none of it gets sucked into your intake. That's why I use nitrous, you can't lose.

 

good point what it the dif between price on filling a nos and co2 bottle

 

Depends where you go. Last time I got my 10lb bottle filled with nitrous it was $35. I think co2 goes for about $25. Call up some local shops to see what it is in your area.

 

i work at a paintball store co2 fills are free =p

 

How long do 10lb bottles work? We have 10lb bottles at work for non-lethal force weapons, and they are pretty small.

 

Nitrous is generally pressurized to somewhere around 1000 or 1200psi, you can get a while out of it. Also don't spray your intercooler for too long or it may freeze and crack.
