what should i buy in order to have the two of these? pistons rods etc..

Nitrous is typically used with turbo engines to spool the larger turbos faster.The parts you use for boost will work with nos/boost.

Just up the boost

Have you ever sprayed with turbo? My stock Ls has lived the entire summer with a fair amount of boost and spray. I picked up a little over a second and 11 mph with just a 18 and 28 jet which is 38hp shot. I have ran the car probobly 50+ qurter mile passes with the spray doing 120+ mph trap speeds and the motor is still as strong as it origanally was. I actually just put a second stage on it and ran about 10 passes with my best being 124 mph and ran to car HARD all weekend. I dont really see what the big deal is as long as you dont get to nitrous happy which I am strarting to but I really want to see what the stock motor is capable of.

im interested in the same thing
dragsol.. your motor is 100% stock?
im not hatin but that seems a little far-fetched

if you have your boost maxed out and then you add nitrous i am thinking <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by W O T &raquo;</TD></TR><TR><TD CLASS="quote"><FONT SIZE="20"> BOOM!</FONT></TD></TR></TABLE>

do people typically turn down the boost a bit to allows the nitrous to do its part?

I think most people run nitrous just in the lower rpm's under the power curve of the turbo. I think it's used more to "supplement" not really "add to" the power of the turbo. Boost dependent triggers create the window under the curve and once boost is at the level, no more nitrous.

I'm hoping some of the big turbo guys poke their heads in here because I'm thinking about building nitrous in to the setup I'm planning. Power goal is 5-600 but I don't want to have to wait on power to come in at 4k when I get into it on the street on those "special" occasion's.

It will be great to hear what they have to say on the topic.

Garage 808 Hatch

I'm looking to spray the whole the track. N2O = cold *** intake charge. plus torque, my b16 needs it

dafuzzbudd

wow that's really freaking cool...
since you're doing this low rpm i'd guess the chances of killing your engine are minimized

.....BS.....

nitrous does actually help spool up your turbo. how does that work? actually quite simple.

compare a built 1.6 (160hp) and a built 2.2(200hp), put a turbo on it and the 2.2 will always spool faster. the 2.2 has more displacement, more power and more exhaust gasses. more exhaust gasses means quicker spool......

if you spray the 1.6 with a 40 shot, it has the same power as the 2.2, and even more exhasut gasses huh why?

because the nitrous cools the intake charge (outside the effect of artificially injecting oxygen) thus allowing denser air into the cilinders creating a bigger bang with more exhaust gasses. this is also the reason why alot of people tend to see a power increase of 100hp while spraying 50 and offcourse a quicker spool.

this is an example and every motor reacts different but the principal remains!

Finally someone who knows what there talking about. A motor is just an airpump if u can get more air in it youll have more exhaust gas. Exhaust gas and heat are what powers the turbo.

I've been running boost + spray on my drive car for the past year. it made 391whp@psi and 511@10psi w/ 100shot. build the motor and fine you a good tuner. here are some pics of my setup(i'm changing stuff right now and going bigger)

i dont really understand why not turn up the boost and make 500 without the spray? you definetly have the set-up to do so with ease. you still have to run race gas at 500 with spray right?

Verry Good info , why the reason to use nitrous in the first place in any application is to add more oxygen for combustion . However why not just inject oxygen and fuel you ask... well Nitrous (N2O) has a cooling effect on the intake charge as stated above so eloquently by wolve This effect is call the Phase Change effect. And more info any one has on nitrous please feel free to read up here http://www.phasechangeracing.com

Thanks for the post, that is great info. I have some questions for you now.

1: Can you please post a dyno chart with both a spray and non-spray pull.

2: What method are you using to introduce the spray? (Dry or wet intake stream before or after turbo, or direct port) **ETA, I didn't see the DP hard lines in the pic before typing this as I was on my mobile PPC.

3: How are you regularly using the setup? I'm wondering if you just use a smaller "shot" under the curve on the street or through out the rev band since 500hp is a "dyno" number and of course useless on the street.

4: What engine management are you used and do you have one tune with 2 maps (one for and one without nitrous) or just tune fat across the board, or have two chip to switch out depending on what situation (street or strip) you are in.

5: *Piggy back on #4, what type of controller/control are you using to dictate the window the nitrous "can" be used in? (RPM window, boost pressure cutoff, little red button on the steering wheel)

I think that's enough questions for now and THANK YOU very much for sharing with us. I was going to make a thread about this and it looks like I wasn't the only one wondering....

you can control boost + turbo through hondata which seems REALLY cool
but a lot seem to have problems hooking it up

I heart that timing pickup and plug on coil setup.

coil on plug, you mean?
