I found this link from the previous owner or NX

Now comes the controversial part...WE DO NOT REQUIRE "RETARDED TIMING" PERIOD!! "Retarded timing" overheats engines, causes extreme exhaust temps, causes your engine to "lay down" in high gear, gives a false sense of power because of overly increased cylinder pressure, burns the oil off the cylinder walls causing the rings to have a "hot foot", knocks the moly off the rings, causes crushed ring lands, burned pistons and burned sparkplugs, burned exhaust valves, etc. Result: You just sacrificed your engine because the "other" brand didn't make a nozzle that atomizes, so they had to make power some way...enter the "retarded timing" solution.
Then they introduced the "dry" system, their thinking was, if we don't atomize the fuel (you can not burn "raw fuel" in the cylinder...it catches fire and goes out the exhaust, causing popping, backfiring, flames out of the headers and other assorted nasty things), then let's just eliminate the fuel through the nozzle and add it later (plus they can sell you another fuel pump that you don't need). Results of a "dry" system are intake manifold back-fires, blown airboxes, mufflers the size of garbage cans, false horsepower claims, & pre-loads and locks-up the fuel-injectors. I'm not trying to scare you, but without knowledge, you can not make an intelligent decision. So now you're asking yourself if the "other" brands make such an inferior product, why are they selling so many. The answer is "advertising & marketing", i.e. "McDonald's"...probably not your first choice for a *good* hamburger, but their name, logo, and advertising are everywhere. Our NX nitrous systems come with a "money back guarantee", if you're not satisfied with the performance and you followed OUR instructions. The "other" brands will not match this guarantee, nor will you get the same answer twice if you call them. This is where "tech" comes in, and our tech comes direct from me, John Stewart, a.k.a. "Mr. Nitrous"...over 21 yrs. in the nitrous industry. I hold the patents on all NX nozzles and all the "Gemini-Twin" plates...the "retired" (as of 4/98) Founder, President, CEO and Engineer of Nitrous Express - Next Generation Technology. I'm now the Consulting Engineer for NX, own Nitrous Warehouse (NX's largest distributor for the last 3 yrs.) and "Mr. Nitrous" Racing.



How can you claim you don't need to retard timing and how can he claim that dry systems cause backfires?

Anyone read this before?

 

Timing does not need to be retarted to run nitrous, I have a stock tune with my 150 NX kit.

 

Correct, you don't HAVE to pull ignition timing to spray. Now, if you have advanced your timing any it's a very good idea to either run a high enough octane fuel or retard the timing that you have added in. There is also nothing wrong with playing it safe and pulling a few degrees.

Like most advertising, there is a bit of truth to it, but you can't take 90% of that at face value.

Every good tuner knows that either with or without nitrous, the optimum timing is dependant on several factors that increase or decrease the speed of the burn in the chamber. You can tune your nitrous system to run well with a lot of timing, or you can tune it to run better with less timing, but you can never use a blanket statement to cover all possibilities.

With that said, in most cases you will not need to reduce the advance from the stock tune unless you are doing something wrong, or spraying well beyond 150hp.

 

Wow if that came from John Stewert it must be old because he passed away over a year ago. Why would you post a conversation over a year old????
Something is fishy here.
Dave

 

That post does seem a little odd. The attitude of the message seems like John and it even sounds like something he would've said, but I have to ask the same question as Dave. Why bring up what looks to be a private conversation from a person that hasn't been with us in a few years? Although it is kinda funny reading that, it brings back memories of having conversations with John about various nitrous products and having listen to his rants, haha (It seemed like the few conversations I had with him always sounded like he was getting worked up, lol.)

 

You may not need to retard timing if you have a stock
factory tune, because that left a lot on the table. But
if you went and put it right up to the ping limit for NA
then you'd best back off some, somehow. Especially
if you also pulled the fueling back to ideal instead of
factory-rich.

People say all kind of things on the Internet, especially
when they're selling stuff (present company excepted,
you see a lot of straight talk here). Without being able
to ask the follow-up question, the opening statement
is not to be relied upon.

 

The statement has truths and non-truths in it.. Too many statements in one paragraph....
Ricky

 

About the only thing I got out of the first post was, McD's is probably not your first choice for a good hamburger, can't argue with that.
Robert

 

I did not know the guy passed away, that really sucks and I have no disrespect for the guy.

I found this in an other nitrous forum in the Faq.

From what I know, the misinformation there is

number one, I know he was refering to the competition and I know that the competition's nozzles vapourize excellent so for Nos to say retard your timing means there has to be truth in that statement.

Also I was reading some info from a well known engine builder and he claims that with a mild nitrous motor you may get away without retard timing but it is reccomended to retard 1 to 2 degrees for every 50 hp of nitrous, that is from peak timing N/A, not factory setting.

and yes on a N/A motor if you retard the timing you will get hotter exaust temps. But with a nitrous motor there is no way that you can get peak cylinder pressure to accur at the right time without retarding timing.

You want to retard timing with a nitrous motor and add more nitrous and fuel to get the most out of it without having detonation issues. A gain in Nitrous hp will outweigh the gain in timing hp is what he was getting at.

 

Too long to read...sorry. Call a living expert.

 

Sounds like he was pretty much trashing the competition to me. I remember talking to him on Ls1.com before...Yeah I go back a little, he had very little to say good about anyone but NX...TNT was on his hitlist back then including the owner James who started out with NX... And TNTs stuff is top-notch.

That being said...RIP

 

John was diffintly a straight forward person. I never really had the pleasure of meeting him but I have been in the buisness long enough to know that no matter if you liked him or disliked him he had a major roll in the nitrous community. There are many people that knew John. I still have people tell me stories about him all the time.I meet people at all these races I worked with that thought very highly of him. I feel like I missed out not knowing him.

Dave

 

He was definately a character, and he could get a little carried away when talking about the various competitors but I think that was because he was very very passionate about what he did.

Cantdrv65 - Yea, like I said, he could and often did get a little out of hand when talking about his products compared to the competition. And James never worked for NX, he worked with John back when they were at Top Gun or maybe even before that. I can't remember. If I remember correctly the animosity between John and James had something to do with disputes on who actually designed certain parts and a couple of other business related issues.

Anyway, that's all in the past and I think John's post should be taken with a grain of salt. Highrevnhp, I would suggest calling or talking to the guys on here to get a 2nd, 3rd or more opinions.
