I never used nitrous on any of my cars.

QUESTION: If I go with a TT kit for my 350Z and install the NOS kit (will be out soon by this company for our car) do I immediately need the intercooler install as well for the turbo?

I will be installing NOS to decrease the lag for the low-end power and since NOS intercools/cool down the intake manifold is intercooler that necessary/or a must at same time?

 

well you dont NEED an intercooler, that would be considered a stage 2 turbo kit, but you should be able to get away with low boost 7-9psi

Nitrous is a great way to cool your intake temps(much like an intercooler) because the compressed Nitrous is very cold. It makes a great combination.
nitrous+boost = weeeeeeeeeeeeeeeeeeeeeee

 

I agree with you that it makes a great combo..

But, now that I took a look at it again, nitrous will not be in the constant use, so therefore the cool down process would have to come from the intercooler and no where else.

Turbos will always spool up at the certain rpm range and nitrous will not be available full-time.

So, 7-9 psi is safe without IC......I am thinking that as well, but can some1 verify this?

 

nitrous+boost = boooooooooooooooooooooooooooooooom

nitrous puts so much stress on the engine, if you are using stock internals and running twin turbo, do not use nitrous! the compression on your car is already very high (10:1) if you add nitrous oxide into the mix, your engine will detonate and boooooooooooooooooooooooooooooooooooooooooooooom.

 

I thought S12 driver's post needed a visual aid, so...

 

Ummmmmmm, hoave you ever even used Nitrous?

Fact-Our stock internals can handle at least another 100-150hp easily

Just because you run nitrous and a turbo doesnt mean youre going to blow the car up, regardless of the high compression. (ang BTW the Eclipse guys run high compression turbo/nitrous setups all day long, among other people)

Running a combo setup is all about tuning, Nitrous is completely safe, by itself or combined with a turbo kit, whether it be twin or single(there really is no difference, usually just the size of the turbos, twins use smaller turbos and have less lag) The reason people blow up cars with Nitrous is becasue they are poorly tuned, youhave to add more fuel when you spray to keep internal temps from increasing. nitrous by itself is not flammable and will not burn so youre not going to "BLOW UP" what it does do is raise internal combustion temps because it allows more fuel and a better but hotter burn.

Short story long..........Nitrous is completely safe when tuned right

If youre going to run both, without an IC I would stay on the lower side of "safe boost" 6-7psi

 

I'm against nitrous. However, I'd probably use nitrous
to help spool up turbos.

 

a small 40-50shot would be perfect.
I an an 80-100hp shot on my 2.5L Avenger for over a year, and the car loved, does a great job of keeping your internals clean No carbon buildup inside the cylinders or heads for me

 

I am not gonna go all out with nitrous, nothing over 75shot to accompany the low end, maybe even less then that.

I also hear that a nitrous "purge kit" which goes directly into the IC system maybe something to consider in the future as well.

The only thing of which I am not certain, if the nitrous "purge kit" setup completely bypasses the engine and a direct IC port only?

 

Purge kit? You can purge nitrous....but what is purge kit?? As far as I know, there are 3 types of nitrous kits, dry, wet, and fogger.

 

I'll see if I can find a pic to be more clear.

from my understanding a purge kit hooks up to the intercooler system to cool it down even more producing mid double digits in overall HP, but I am not that familiar how it works yet...

I am searching as we speak.

 

Almost all Nitrous kit manufacturerss sell some kind of purge valve, all a purge valve does is release pressure from the nitrous lines to make sure there is no air in the lines, so when you spray, youre spraying all Nitrous, and not air for the first few seconds.

You can add a jet from the purge valve that connects to the "IN" side of an Turbo Intercooler to help further cool the air, the nitrous still eventaully makes it into the engine, just not in as concentrated a form. Its much like water injectors used to cool the air in a turbo system. Hope this helps

 

I am installing a 50 shot kit in my Z this week, with purge, bottle opener and heater and gauge. Since the car is Drive by wire I am probably gonna stick the switch under the gas pedal. As for the turbos, We are planning stages right now. My friends shop does alot of custom turbos. Everything from fabrication to tuning. Hope to have it in by Spring.

 

Even if it's not the high compression thats causing problem, assuming you don't make even a little mistake on the tuning, it's highly unlikely that your engine can take 130+ from the TT kit and then 50-100 shot of nitrous, the internal simply will not take that much power. But if you think it can be done, then try it prove me (and others) wrong.

 

I would change the pistons out before going turbo..

 

Nitrous and 10lbs of SC boost has worked well for me on my VQ30

 

The DSM cars come with either 8:0:1 or 8:5:1 compression depending on generation. I wouldn't exactly call that "high" compression.

 

Actually, no the 420a is a 10:1 compression. anyway as you can see by the dyno above, hes running 10psi and nitrous, thats pretty god proof dont ya think?

My old avenger ccould run a 100hp shot of nitrous ALL day long, so did wadd3456, so i KNOW ours can handle more than that

NICE!!
