Going to run N02 w/ my blower.
I'm not sure yet but I was going to run a light shot of N02 to fend off any one I race whos car is a bit more then I can chew.
I wasn thinking of no more then a 100 shot. I'm thinking of plumbing the nozzle into the intercooler for more stealth and to cool the intercooler off more. Or should I just use a plate system?
Anyone doing this? I have a full forged bottom end so I am not worried about that. And I get minumal (4-5 usually) knock counts from the Knock sensor running 12 psi as it is.

Run a plate system. If you shoot it into the intercooler it may actually get warmed up by the intercooler and if you shoot fuel into the intercooler the fuel will condense inside the intercooler and you will run lean. KA BOOM!
Make sure your fuel system is up to delvering the massive amounts of fuel that will be needed to feed the motor on boost and with the solenoids open.

running a plate system may get you into trouble.........you could certainly make it work though.
or you could go with what i'm using wich is a nx kit that is made for intercooled applications. addes 60-70 more horsepower with out any additional strain. or at least so they say.

Are you running an FMU now? If that is the case, you may have troubles doing it.
Like these other guys said just make sure you have enough fuel. The best way to do it I think would be using big injectors that you could tune on the car with spray and boost. No FMU. The FMU will make it difficult to get the fuel curves correct.

Yes I am running an FMU Guido. I am about to purchase new injectors as my 24lb/hr SVO's cant even spray enough fuel for 12 psi of boost under 75 psi of fuel pressure.
I was going to get 30's or 36's and continue to run my FMU.
In a few months I am also going to purchase a set of AFR 190cc heads with some hand port work done to them.
My goal is solid 11's with motor and boost.
I was going to run a light shot of N02 just to fend off anyone my car cant edge out. There are some fast 5.0's and LS1's in my area!
But right now my best run has been a 12.81 E.T. at 108 mph with a 2.1 60 ft on street tires. Its a mid 12 sec car on slicks.
Will it just be tricky to get my fuel curve right or near impossible?

fuel condense inside the IC and make it run lean? can you please explain that one to me

I'm interested in this subject too. I'm planning to get a D1sc with FMU and thought about a 50 shot just incase. I've seen countless vipers running boost and N20. But how cn we do it??? Guido, your wisdom please.

here are a few educated opinions from someone who's helped on a few of these setups:
1)plate systems dont work well with boost. problem is that the compressed air can actually push the n20/fuel too far into the intake and cause distribution problems in certain cylinders. thats why it is "recommended" to put a single nozzle about 1 foot from the TB
2)using an FMU with nitrous is going to be a PITA. you could probably get it to work, but it would really be difficult. i dont advise it. If you still wish to use a FMU (which is absolutely fine, i know a few who've used them up to 600hp applications) just get a nitrous nozzle and spray the actual nitrous onto the intercooler to lower inlet air temps that much more to gain the hp
3)do it correctly and setup an entire fuel system for it or get a custom chip and no FMU

Well if I were to use a dry system at the intercooler I'd need larger injectors, a 1 or 2 bar MAP sensor and a custom chip. I was wondering if I could use a small wet system and not have to worry about the fuel condensing in the intercooler like Damon said.
I'm getting pretty good at using my FMU to get correct fuel measurments. Its not as exact as a custom burnt chip but by using differant plates in the FMU and tuning with the bleeder screw its works alright.

im not talking about shooting a dry system INTO the intercooler i'm talking about shooting nitrous ONTO the intercooler to lower the ACTUAL temperature of the COMPRESSED AIR out of the BLOWER
go to NX site, its called the N-tercooler for super/turbocharged applications. You can make one up yourself, but this will show you what i'm talking about
true.....with ONE poweradder
not

There is N-tercooler information here:

Does that actually work as well as they make out?

guido is right about the FMU and fuel curves, keep the "NAWS :sillylol:" shot on the small side to get the power and lower the over rich affect. there is a guy in chat to see he goes 9 and runs the plate and a vortech http://darcom.home.texas.net/darcom/Z28_PAGEx.html
