My setup is 12.5:1 cp pistons, IB-spec rods, Hotshot header,70mm throttle, ported intake manifold,stock head,hondata s200, i think im going to buy the rocket h24x cams.
I would like to know how much nitrous i can use with my setup...
You can recommend how much regarding fuel 93octane,100octane any setup you can think of..
Thank you

 

nawzzzzzzzzzzzzz

 

35-75 depending on tune. depending on how far you build the motor will allow you to add more. but tune is the most important. do a search on it you will find some info

 

A good rule of thumb is no more than half your stock hp. Since you are built, 100 shot will be a good start, dont forget its all in the tune. I m not sure if the s200 has nitrous maps, but if so, then your tuner will probably use them to retard ignition. If you tune it with 100 octane, you may not have to retard ignition, but that depends on what the dyno is telling you.

 

as much as you can suck down while watching "Fast n the Furious" 1/2/3..
Good rule of thumb, if you call it Nawws, dont try to run it.

 

I don't know how confident I would be running it with 12.5:1 CR. You need atleast 93 octane for even a small shot, but with 12.5:1, I don't care if you are built or not, you will probably need something higher. Pulling some timing and colder plugs are a must. How big of a shot you can run is up to your tuner. It probably won't be huge, unless he has a lot of confidence in the build. Maybe 65-75 shot at best.

 

YOU'LL BLOW THE WELDS ON THE INTAKE MANIFOLDD!!!!!!!!

 

I had to tune my 55 shot on 92octane.....had to retard 1degrees.U should be real safe w 1/2 ur hp....especially if u have solid pistons.

 

0 shot

 

tune tune tune.....

if you can find an E85 pump... try and tune on that... its 106 octane if im not mistaken... maybe 108.....

 

your motor is not built for nitrous, maybe a 25-shot using E85 or race fuel with some ignition retard, if you wanted to use nitrous you should have thought of that before building your motor

where in the original post did that guy see that he was "built"

Whats wrong with my reply
He has aftermarket pistons and rods, bottom end is built enough to handle it.

For nitrous all you need is stronger rods. As long as its tuned and it doesnt detonate, he should be good.

 

LOL. Nice creative replies!!

So for those who are replying seriously thank you.

 

well he didn't really mention what type of cp pistons he has.....the design makes a difference for a nitrous application......i don't see 12.5:1 in their catalogue for h22, so unless the op knows the application he ordered for, i don't know where to find the answer
there is also no mention of sleeving the block, which again would be related to what type of pistons he got from cp

at the very least probably going to need a fuel pump as well unless he plans on running lean and frying some valves......since he has not mentioned upgrading those either

as far as his cams are concerned, well i'll just quote......
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">Optimum cam timing for a nitrous motor will be different than optimum timing for that same motor off the bottle, so you will have to make a choice as to whether you want the most power with or without nitrous. Obviously if you are driving the car on the street most of the time, you will want the best power off the bottle. If you find that you can spare some power to make your car faster at the track, picking a camshaft to favor nitrous can make a substantial difference when nitrous is in use. If course it is a trade off, but usually the power that you make on the bottle, will be far greater than the amount lost off the bottle. </TD></TR></TABLE>

the intake needs to remain pretty much the same, but the exhaust needs more duration, an earlier opening point and an earlier closing point. To make this happen, you need to use a dual pattern cam with more exhaust timing, and a wider lobe separation angle. Cam's with 112-116° lobe separations are common is nitrous motors. To keep the intake timing the same, you must install the cam advanced, usually 6-8° advanced. The good things about this are that advancing a cam will bring more low-end (at a trade off of top-end) when running without the nitrous and the wider lobe center angle will also help idle and vacuum. Even the most radical nitrous profiles are usually pretty tame on the street. Ultra high lift cams are not need to make power with nitrous. On the exhaust side, the low lift flow is the most important thing, and must be dealt with much more seriously than high lift flow.</TD></TR></TABLE>

i really don't understand why people can't do research on their own.....at least some basic research so they can ask more informed and specifc questions

Quoting myself from the last NAWZS thread...

 

why does it seem like everyone wants to ask the SAME questions at the SAME time as everyone else??? Theres like 3 threads about "NOS, NAWWS, NITRO, F&F JUICE" that have come up in the past 2 days...Jeez!!!!

Search!

Trial and Error is the best!

Like everyone else is saying...TUNE!!!!!!!!!!!!

 

The pistons are Cp gas ported, lightweight pistons 89mm, the block has darton sleeves. You dont have to order from a catalog to have what you want, you can custom make them ordered them through raceengineering.com, I think that is why they costed me so much and i had to wait for them like 4 months. I'll use a 255 fuel pump and 440 inyectors.
In think that this forum is to get informed, i used search but nothing concrete came up, just some ******** just making bull**** replies.
If you already answered some post that looks the same as this, dont read it and dont answer.
The engine will be off the bottle most of the time, the bottle will be for some times.
Thank you silver surfer for your quotes and the other people that replied to help.
And jut put nawz just as a joke. i you check in another forum in honda-tech i put NOS.
I dont know what is the big deal that you make for a simple word.

And foe the one that quoted that they should make entrance tests for honda-tech
send me one, i'll score better than you, Moron.

 

I say start off small and track your progress. I have previously used a 100 shot and that was on stock internals but all it did was spin tires. I am currently working on a 2 stage system so I can actually launch with Nitrous instead of launching all motor and spraying at the top of 1st.
Sounds like a pretty mean setup youve got there so you should be no stranger to Dyno Time. Because of how nitrous works, its possible to blow your motor with a small shot, but be ok with a larger shot.
Tuning and Spark Plugs are the key to Nitrous Fun or NAWS Disaster!
With that much compression I would think you'd want to run 100 octane. The other option is mxing your own Race Fuel like I do with Toluene(a 114-117 octane paint treatment avaiable at paint stores)
Let me know if you have more questions.....Do yourself a favor when you try to figure stuff out in this HT.com World. Find someone who knows what theyre talking about and talk to them. TOO Many attention getters on the forums!

 

Thanks. The shot will be used for 2nd , the engine is in a ek hatch so i guess i dont need to spray on first, even on the stock engine she had a lot of wheel spin.

 

secure the floor boards FTW!!

Well that changes things!
I would learn how to drive the current setup 1st and start very very small!!! You already have a solid 12 sec car once you learn to drive it. I would try using nitrous unless you have some slicks on hand!
