NITROUS OXIDE ( nos / n2o ) advice forum

Hello all,

My name is Alex
Hi Alex glad to see you made it here and sorry for the late response.

While I'm not completely new to nitrous, I am new to using nitrous CORRECTLY. I don't want past knowledge and experience, which is tainted by U.S. company and forum information, to hinder my new learning experience hear in the School of NOSwarts!
Shame about the tainted experience but you can now appreciate WON even better, as most people who choose WON first don't appreciate just how lucky they are that they did.

So here we go!

Here is the overall location for the Pulsoids. They are away from the exhaust system and most high heat components. I had to keep in mind the location of the injector for the fluids to have the shortest routing possible and also avoid the brake fluid reservoir.
Looks to me like you can locate the Crossfire JUST before the TB.

Pulsoids are mounted to a removable plate where the computer mounts to. It's replaceable from the manufacturer and easy to modify and manipulate. Remember, it is a mock-up so the computer is not secured to the plate!
I'm sure that will be fine when its finalised.

I'm still waiting for a fuel supply hose to draw fuel for the Pulsoid, some NGK 7 plugs (non-projected), and a retainer for the injector so I'm a bit on hold for that.
Very sorry about the retainer, that was my fault as I don't normally have to deal with packing orders but my usual packer was off ill.

Fortunately that's the minor stuff, though I hit a bit of a snag during the mock-up. While attaching the pulsoids to the supplied mounting brackets, the top of the coil that threads into the CNC body came loose and it turned about 1/4 turn from it's factory position. I tightened it back up (by hand but good and tight) to put it back where it was but I can't be 100% certain that it's in the position that it was as delivered. I know the adjustment screw under the jet holder is calibrated, but I just want to be sure that the coil top is not of high calibration as well.

Should I return it to WON to have it inspected, torque the cap to a specific value (I have those tools and expertise), or will a good tightening be sufficient?
As long as its tight it should be fine and shouldn't affect the functionality or the setting of it.

I did read the X-10 manual and optimization process and there was no mention of this so I thought I'd better ask. I always ask and NEVER assume.
Wise man!

Alex (U.S. customer)

By the way, I compared this kit to the old NOS and a Dynotune one that I have and the quality of WON is of no comparison. I made the right choice. Thanks, Trev, your battles on other forums made me take a GOOD look into your products and the TRUTH of NITROUS!
Very pleased to hear it and thank you for such appreciative words.

No worries; I know you're a busy man. Especially one who's trying to run a company while responding to posts! Once again, EXCEPTIONAL SERVICE AND DEDICATION!
It's always a pleasure to have my efforts appreciated.

Indeed. Even when I broke things, I tried to figure out why, but the information available at the time was typical nitrous B.S.
You'll ONLY get the true FACTS here. I won't allow any BS or untruths on my forum. Just a shame that more people don't benefit from it all. Having said that, I know from the forum view stats that a large number of American's do spend time reading my posts and I've no doubt that most of them will be using US JUNK kits, as we don't have a big market share there yet.

I just used the measurement to see mark the maximum distance I was considering the injector installation. It's good to hear that I could mount it so closely; apart from quicker response, it keeps things neater. Jets will be easily accessible in this location as well.
Easy jet access is very important as it means you're more likely to optimise the settings, than if you couldn't get at them.

Both pulsoids will be angled in the same manner because I know it will eat my brain if they don't match! Could it be OCD or perfectionism?
Perfectionism is a cover story for OCD and I know that from personal experience. It's my own perfectionism/OCD that has lead to the PERFECT products I've designed/created but it also wastes a great deal of my time, when I can't do anything without doing it in the best possible way. :-(

No, THANK YOU for putting up with my infinite questions and providing so much assistance.
It's always a pleasure when its appreciated.

I've heard a lot of bad things abut American systems

Yes, they are horrid. I've owned a few systems over the years and they all have the same qualities: poor design and excellent marketing. They prey on the new users by finding newer and better ways to make their systems look good while being the same junk that's been sold for decades.
ABSOLUTELY CORRECT and ESPECIALLY "They PREY on new users" and it's a DESPICABLE policy.

At first, I didn't believe it. I thought that the U.S. stuff was improving as time went on, but in reality, the only improvements are aesthetics and profit margins.
Correct again as PROFIT is ALL they are concerned about and they don't give a damn about the customer. HolleyNOS refused to buy/sell my Pulsoids instead of their generic JUNK, because THEY'D LOSE SALES OF SERVICE KITS & THEY MAKE MORE PROFIT ON THOSE THAN ANYTHING ELSE!!!!!

For example, when I first heard of the "Zex box", I thought it contained some complex electronic circuitry to "monitor" nitrous and fuel pressures to maintain the optimum mixture (as per the marketing verbage). Yet, under that pretty purple cover was nothing but a few bits of cheap,brass fittings and a VERY ugly, generic solenoid. Considering that these types of solenoids require regular servicing, there is no provision in the instruction manuals to inspect the solenoid in the Zex box. So how is a customer supposed to know if the solenoid is in need of replacement? When it's too late and the engine is destroyed from a faulty solenoid? Do they really expect a customer to send in their Zex box back to head-quarters after every 20 pounds of nitrous? Those shipping costs are NOT CHEAP!
The Zex con is DISGUSTING and one of the worst out there. It's such a shame that more people are not aware of it as you now are. I actually publicised this many years ago by posting pictures of the internals on here and there are even worse aspects to it than you have covered.

These are questions are started asking myself after researching why WON systems were so different in appearance. And after hours of reading on this forum, I realized that all of Trev's words are based on FACT rather than clever marketing. Since I do have a brain (that works!), I began thinking about each design element in WON systems and how they protect the nitrous oxide liquid from changing into a gaseous state UNTIL the point of release into the engine. I also thought deeply about the Pulsoids compared to 'other' kits' solenoids. At first, I didn't even know that Pulsoids lasted forever, yet after rebuilding generic NOS brand solenoids (at $50 to $70 each kit for both fuel AND nitrous ~ $120 average) I knew that I wanted to chuck them in the bin and obtain the Pulsoids.
My first experience of using a US brand nitrous kit (NOS) nearly cost me my life, when the fuel solenoid failed to open (due to unsuitable materials being used as seals), causing a backfire which set the bike on fire. From that day to this my TOP priority has been to produce products that perform the BEST its possible to achieve, to ensure my customers don't run the life threatening risks that they do when using other products.

Of course, since the nozzle of my kit is a design of the 1970's (NOS 13700), I thought I'd better upgrade the whole system to obtain the reliability I've desired from a nitrous system.

I think I was EXTREMELY fortunate not to damage anything with that kit over the 10 years of ownership, and that was due to constantly checking the solenoids for condition. After every few bottles, solenoid inspections tend to get VERY tedious; it made me NOT want to use nitrous knowing that I would have to check them again. NOT FUN!
You were VERY LUCKY and its ing that people buying other brands, have to RELY ON LUCK and regular maintenance to get an acceptable result. With WON systems the reverse is the case, you'd have to be VERY UNLUCKY to experience ANY kind of failure of our components. In 35 years of this business and having sold many hundreds of thousands of products, I can't remember a single case of a customer being unlucky enough to suffer a major problem and I can probably count the minor problems on one hand.

I can't wait to experience nitrous-oxide again without those concerns![/color]
Which is how it should be.

The Zex con is DISGUSTING and one of the worst out there. It's such a shame that more people are not aware of it as you now are. I actually publicised this many years ago by posting pictures of the internals on here and there are even worse aspects to it than you have covered.

Thank you, Trev for the positive critique!

Now down to BUSINESS!!!

I performed several brief 2nd gear runs to make sure that there were no unusual sounds from the engine, in fact the engine responded EXCELLENTLY with very noticeable increases of power and exhaust note. Needless to say, this brought back so many good memories!

After stopping to check the condition of the spark plugs (for signs of detonation or melting), I then proceeded to a 30-90 mph test, which is 2nd and 3rd gear for my car. The result were SPOT ON!

Spark plug analysis:

NOTE: Each plug looks EXACTLY the same with minor variations. The nitrous/fuel plume dispersion is the BEST I've experienced. EVEN ON SMALL SHOTS, I was able to discern lean cylinders to rich ones with my NOS and NX kits!

EXCELLENT results, excellent report and excellent observations, if only more people were so aware of the difference between right (WON) and wrong (the REST), they could all stop suffering and enjoy nitrous instead.

Overall:
I'm concerned with the timing mark, but that timing mark may be due to non-nitrous full power passes. I didn't make enough nitrous passes to form that mark. NOTE: ALL CHECKS PERFORMED AFTER IMMEDIATE ENGINE SHUT DOWN AFTER EACH FULL POWER PASS. This is to ensure proper plug analysis. Therefore, these plugs were pulled RIGHT AFTER a nitrous pass and replaced with a different set to drive home.
Most modern engines have det sensor and self adjust the timing but if yours doesn't it would certainly help to try and retard the timing a couple of degrees, even if those results are NA. An alternative is to add a progressive controller, as adding less at low RPM and more as they ramp up, avoids the high low rpm loads that fixed hit kits cause.
Excellent plug inspection proceedure and analysis.

When the nitrous engaged, it felt extremely strong and SMOOTH. I've never felt such a 'nice' increase in power as opposed to a generic "shit kit". I am extremely happy with today's results!
VERY PLEASED to see you say that as most people (who haven't tried both), don't believe that there can be a difference between how a WON system 'delivers' the power relative to how other kits do.
Our UNIQUE use of nylon pipe and metering jets located at the Pulsoids create a relatively SOFT HIT that then grows with time (even on a fixed hit), whereas with ALL other kits there is either a delay if the braided hose isn't purged or there is an initial surge that then fades away if it is purged. ONLY the WON way delivers the nitrous and fuel CORRECTLY and achieves the desired effect.

Now it looks like I'll need a clutch too. 3rd gear engagement causes it to slip!
That's the kind of problem most customers are happy to have to deal with.
BTW a progressive controller would help to alleviate that problem and we have a couple of used options available at present so that's at least 3 good reasons for going progressive and I haven't even scratched the surface of the HUGE number of benefits they offer.

Oh, by the way:

Note the TEFLON TAPE!?
Garbage, simply garbage!

Yes that's another example of their PATHETIC INCOMPETENCE and one that we categorically warn AGAINST DOING, as PTFE tape shreds when parts are screwed together and can easily block filters.

That is IF the system includes one in the first place, and even then it would be nothing more than a SCREEN rather than a filter.

How anyone could feel that such a piece of JUNK warranted a Patent is beyond me.

A scumbag would.

I can say with all HONESTY that I am DEEPLY PROUD OF ALL MY PRODUCTS and if I wasn't I wouldn't be selling them.

And that's why your products are AWESOME and continue to IMPROVE unlike other jerkoff companies.

my car does have a performance tune for a completely stock car, which increases boost and changes timing curves to match. I suspect the timing is increased to hold power under high & hot boost pressures. However, I've scrutinized these plugs using my 10 power magnifying glass and saw no evidence of detonation. Not one single speck of metal at all! Beyond that, this engine has a high sensitivity detonation sensor as it was designed to be used with 9.5:1 compression and 87 octane. ANY sign of det and the boost will fall and timing will retard.
For some reason I didn't realise your car was turbo charged until now. Being a turbo explains a great deal!!!! Unlike NA engines the timing does NOT need to be retarded when adding nitrous, as the extreme cooling effect makes the charge less prone to detonation than on boost alone, so if anything you could advance the timing.
If there were any doubt about that statement, the condition of your plugs prove it to be correct.

If I didn't try it, I WOULDN'T have believed it either. The nitrous delivery simply felt like more boost from the turbo.
Which is how I intended it to be, as it's more USABLE that way. I remember taking a magazine journalist for a test drive one day, I activated the nitrous and these were his words; "Oh shit... OH SHIT.... OH SHITTTTT....... OH SHITTTTTTTTT.......... OH SHITTTTTTTTTTT!!!!!!!! as the engine just kept pulling harder and harder.

That has to be the ugliest kit I have ever seen. I certainly wouldn't have that fitted to my wheelchair

You can't polish a turd though hahaha

Indeed you can't! You should see the types of complaints on their forum: it's full of failures surrounding that potted electrical circuit. One person even claimed that they bought EVERYTHING Zex, and over time EVERY component failed at least once. I just felt sorry for that person.
