hey i wanted to know if anyone here has a high compression motor and is spraying it useing stock sleeves? Just wantin to know how it is workin out and what size shots etc...

 

most of the street cars here in socal arnt squeezing high comp motors. the only high comp motors that i know of are pretty much track only cars. high comp with the bottle sounds like a recipe for disaster. if they do squeeze, its a small shot. hope this helps.

 

how high of comp. are we talking about 11.5 and up?

i have a couple "proprietary" street racer customers who I built their stock sleeved motors with forged pistons and steel rods, i put blockguard in there for them and they run fluidyne radiators ... compression on one car is close to 13:1 with a 75 wet shot for backup in case they losing ... they run an AEM which I setup for with switch to pull timing when on steroids.

I haven;t heard from them in a couple years ... and heard they still racing so I'm sure the motor still working well LOL...

Spraying on High Comp is very possible. **** look at my car that is for sale. I built it for spray.

I know people that have sprayed over 150 shot on 12.5:1.

You have to be safe though.

This is what I recommend:
1. Tune motor at stock timing.
2. Make sure if running chipped ecu or hondata to not run agressive timing maps.
3. Get a MSD Digital 6 Plus (has built in nitrous retard which only works when u spray) or Hondata S200 which has a nitrous retard built in I believe (u might want to research this)
4. Whatever injectors your tuned at should be fine, since nitrous systems do there own fuel delivery.

Basically, U will not get full all motor potential due to the mild timing, but u will love the nitrous.

Also, I recommend direct port setup only, so all cylinders get equal nitrous.

Another thing. Only spray on high comp forged pistons.
Example: Do not spray on say ctr's in a gs-r. Your motor will go bye bye.

wow. ive lesarned lots from your posts myself. thats cool. if done right, you can sueeze high comp.

 

I have a Jdm ITR running 12.5:1 cr on stock sleeves. I was running a 60 hp wet shot, but plan on bumping it up to a 90 shot in the spring

 

What is the deal with all this nitrous crap in this forum all of the sudden? Last time I checked, all motor cars did not have nitrous.

 

can anyone verify that the hondata s200 has a nitrous retard built into it?

 

Nitrous does perform better in high compression cars. I dont understand all this (FS: 9.1 C/R JE Piston LS/VTEC! GREAT FOR NITROUS!) crap. No its not great for nitrous. With nitrous its not compression your worried about. Its always timing and fuel delivery. If either one of those goes south you should here a loud pop and your motor will drive home with its tail between its legs. I know, first B16A i owned, put it on 100shot direct port when I knew absolutly zero and the rest is history. No but in reality its late and im rambling. DETONATION is not your friend. Oh yeah either is valve float or the teletubbies, jew people,kosher hot dogs, and kia motors. Don ask why. Its in the JDM book of elitist law.

I did a little research on it. If you want you can read about it HERE.

It only works with a dry nitrous setup. I wouldn't recommend it. Go the MSD Digital 6 plus route.

Why can't you run max timing on your engine and just retard like 5 or 6 degrees when using nitrous ?? That way you would be safe or not ?????

 

Yes the S200 will work. I have it on my wet setup now. Works great!! It taps into the power steering relay and uses that to switch. It will work on eight a wet or dry setup. FYI...

 

high CR + juice = FUN!

do it, but tune it right. that's the bottom line.

talk to me about a b18c5 w/ 12.1:1, toda spec A's and 100 shot wet. god damn, white boy... that **** PULLS! 289whp.

A dry Nitrous setup is be used (where the fuel is supplied by the ECU)

At the same time the ECU switches the Nitrous on, it will supply an additional amount of fuel to the injectors, and optionally retard the ignition timing.</TD></TR></TABLE>

If you can make it not add additional fuel, then it will work. If you are making it add additional fuel when spraying wet you are then running it way to rich.

But it does retard timing which is a good thing. I'm gonna talk to my tuner about this. If anyone on here is familiar with tuning Hondata with a wet shot please chime in.

You can! MSD makes a timing retard boxes that you can wire in with your nitrous system that will retard timing when the solenoids are activated and run whatever timing you have set when it's not activated. You must use an MSD igniton though!

cause your motor will run slow as *** when your not on the juice!

Bwahaha, best post ever. Funny ****!

 

we've tuned over 350whp all juice on stock sleeves with our dry setup (fuel is added through added pulse width), but not with HC...no luck squeezing appreciable amounts over 11:1: detonation comes a knocking . we just see too much detonation on the plugs to feel comfortable with 91 oct.

 

nitrous likes compression, but tuning is key.

I have the Hondata S200 system on my car controlling my nitrous system as well and it's a wet kit. Because Hondata is a programable system it'll only do what you program it to and if you don't tell it to add fuel when spraying, it won't.

And for everyone else that keeps saying that nitrous loves compression, this isn't entirely true. Nitrous and boost should be considerd the same thing as they have the same effect on an engine internally, no difference. However a boosted engine runs boost all the time so a lower compression level will have little effect on the vehicles performance daily driven. A nitrous engine runs all motor 99% of the time and will make poor power on low compression so low compression isn't often used with nitrous for this reason only. Boost and nitrous work BETTER on a higher compression engine, but the margin for error when tuning the engine becomes very slim. Get it wrong and bad things happen quickly, get it right and you have one awesome performing car, on or off the bottle/boost.

From what I've heard, retard one degree for every 50HP of nitrous. Not sure how true, I'd definatley retard when on the bottle, use a set of NGK 7 or 8 plugs, and Tune.

Yep, that's the general rule of thumb that's recommended by NX for tuning nitrous engines. When spraying on high compression engines the timing retard required is greater. It's probably a good idea for people that are spraying on high compression to call their nitrous brand companies for tuning baselines, around their specific engine configuration, who want to know what to set their ignition timing at.
