it all depends on how fast you want to buy a new engine because i cant believe tha this can be at all good or even harmless to your engine. Those things are only suppose to do so many rpm's and when you make it do more than your askin for trouble.
uh, wouldnt that be like switching imediatly to 100% nitro from 20% (or whatever you run) instantly?...yeaa....i dont think thats gonna work too well....
Nitrous Express isn't a small time operation. They are very good at what they do and i seriously doublt they'd waste their time and money marketing this product if it didn't work. I have juiced a few engines on a bench, but never on a driving car. It will definately work. I don't like the NX solenoid though, too big and heavy. You can get air valves that are used to activate air powered landing gear for planes the would be a lot lighter and smaller. The down side to those is that they are mechanically operated instead of electric, so the throttle linkage would be a pain, or you could use a three channel radio and an extra servo, but thats weight too.
Also the true advantage of nitrous isn't really added rpm, it's added power through out the rpm range. It really helps acceleration, and there is a lot of additional torqe in the lower rpms. I guess the biggest help to land speed racing is that it would allow you to pull a bigger gear.
I think 5 minutes would be more than enough time to set the speed record. Besides, nitrous isn't really designed to be run continuosly. Drag cars run it the whole 1/4 mile, but that only takes a few seconds. Even a slow car on juice probably only needs it for 12 or 13 seconds. I don't think land speed racing is the best use for nitrous, but used properly it could be beneficial.
Nitro is a powerful fuel. Nitro is the number one reason full scale top fule dragsters run 330mph in 4.5 seconds. Take the pop away and force them to run alcohol and you'd set the class back 10 or 15 years. Now having said that it used to be common to see the funny car guys in particular run nitrous along with 95-98% nitromethenol. Rules prohibit that practice now. My point is, 20% nitro may be better than nitrous, but 20% + nitrous is better yet!
for $200 u can perfectly get your engine(s) ported and maxed out to their limit. All it will gives u is like 2-4 pounds of crap. If it worked than everyone would be setting new records for speed . Or you can use that money to buy a better engine. Even if it worked do u think your engine,bearings,etc can withstand and extra claimed 10k+ rpms and the heat? you would lose compression and that time and everything would weaken. That bottle wouldnt last for 5 min. Maybe 20 seconds at tops and the engine wouldnt survive wot for that long.....
my problem with the system(besides weight), is the fact that there is no technical data to support any increase in power. nor is there any fuel enrichment device, that alone makes the system useless. first thing i want to see is dyno charts from an indipendent testing panel and a fuel enrichment system.. just because someone sells them, doesn't necessarily meen they work. turbonaters, magnets on your fuel lines, resisters on your coil wires, all a bunch of snake oil! i've seen NX stickers on cheap plastic toys at wallmart. that tells me their trying to make money anyway they can!
ok guys I was a dealer for NX for 2 years and heres the deal. Nitrous will add gobs of torque. Yes you can spend all this money and have your engine cut and modded and blah blah but it will only get you so far. I can promise you that nitrous will wake your motor up!!! I did a review ona kit from Jags a while back. Granted the kit wasnt al that wonderful, the results of a nitro motor on nitrous oxide were phenomenal. All this about blowing the piston thru the head and all, isnt going to happen. The glow plug simply goes out before you ever get to that point. We installed the Jags kit in a Monster GT, a bone stock MGT at that. When finished the truck would almost wheelie going into second gear because it was accelerating sooooooo hard on the shift. If any of you have ever driven a stock MGT you know that power going into second gear is dismal at best. Before you claim that something doesnt work do your homework first so that you can back it up.
As for the NX system, yea its big and heavy but, I promise you the power gains will waaaaaay override the amount of weight your adding. I am building a wet nitrous system as we speak for my RC Top Fuel Car. Its a wet system. For those of you who dont know what that means. A wet system sprays fuel and nitrous at the same time. This way you have fuel to support the nitrous and arent relying on tank pressure to supply the needed fuel.
Either way nitrous works, you should give it a try. Your outlook on nitro rc will change. I promise.. If you have any questions about this just ask away.

oh and as for their names on the toys at Wal Mart, that wasnt their doing per se.. That was the movie peoples doing. NOS sponsored the Fast and Furious. NX sponsored the second one. With that came endorsements for movie and or promotional items and or items that stem from that movie. Hence the reason for all of the NX stuff at Wal MArt. However, if you'll notice some of the toys are like a hot wheels thing that looks like a big nitrous bottle.. and its blue.. The makers of the toys thought that NOS was more popular and to a point it is. So they made the bottle blue, which is NOS standard colors, rather than white like the standard NX color. So you see they arent all smoke and mirrors and gimmicks.
shouldn't have NX done their homework to back up their claims, like charts , graphs and formulas? i never said it wouldn't work. it's just not looking good for an engine. why don't they sell a wet kit? whats the change in combustion chamber temps? how about damage to rod bearings and detonation. these are all things a would want to know before spending money on something that might destroy a $300 engine after 6 runs.
First off NX did their homework or they wouldn't release it. If you notice they give you a pill size. This is their homework. Nitrous pills come in various sizes that portray flow rate at a given PSI. Too little does nothing, too much just blows the glow plug.
They dont sell a wet kit because that would be more tuning than more people want to mess with. They (NX) can pill the system conservatively and the general public can use it easily. When people buy a product that requires immense amounts of tuning to get it right they tend to get irritated and then bad mouth the company. So unless your selling audience is a very experienced group of people they try to keep it simple.
As for damage to rod bearings, I'm not going to lie to you and say that you engine is going to live indefinately on the juice but, as with any power adder things are going to wear quicker. I dont see them just grenading unless the user goes hog wild and does something like removes the pill all together to get maximum flow or something similar. As for combustion chamber temps, sure they are going to go up but your not going to be 'racing' on the bottle anyways. Put it this way. The bottles are tiny. Ever seen a whippet refill?? Looks like a small version of a CO2 cartridge. They dont last long. With the Jags kit I could spray the MGT twice on a bottle. That was one really awesome run of about a 2 second burst and then a kinda ok run of about 2 sec. On a 4-5 second spray temps arent going to escalate enough to damage anything. Once again like I said earlier, any type of power adder whether it be a higher nitro content fuel, nitrous, prope, or whatever else they have out there is going to put more stress on the internals. Thats part of the price we pay to go faster. As for the destroying a $300 motor after 6 runs, well we went thru the 14 bottles of nitrous that Jags sent us and all we had happen was a few popped glow plugs. As a matter of fact that truck has been sold to a friend who has put probably another 2 gallons of fuel thru that 21 since he has had it and the truck still runs great. The biggest safety margin we have with nitro motors running nitrous is the glow plug. Unlike a standard spark iginition system we rely on a small coil thats heated via the combustion process. If the combustion process becomes too much then the coil simply breaks and stops retaining heat. Therefore the engine dies and the run is over. So as for prolonged detonation, well there isnt any, the plug dies way before damaging detonation ever occurs.
If you think that NX should put more info on their site about the kit then by all means shoot them an email and tell them. I am simply trying to educate the people who think that it wont work or may cause damage to their engines. Anything can cause damage if used improperly. Nitrous has gotten a bad rap for many many years. However when used properly the non flammable go gas we have all come to love can give your rc experience a whole new twist.

Honestly how much is it good for 2-4 mph faster. Maybe 1-3 hp. I don't see a shot lasting or doing any good. Unless like said you really adjust for a 2-4mph. Or 1-3HP. I Run a Camaro on 275 Shot of TNT. And a ZX-11 on a 40 of NOS. So I'm tempted to buy the Nitrous Kit. But right now for me I don't think it's worth it. Besides theres a Supercharger kit out also. But I have yet to hear from anyone actually running Nitrous or a Supercharger. although the guy from NX spoke of it. I don't recall him saying he ran it on any of his RC Kits. (I could Be Wrong).
As for the spur gear, yes I dont see how it could hurt anything. Especially since its already stripping them now without it.
Nitrous is just coming around in the hobby industry. To my knowledge Jags was the first company to offer a nitrous system designed for an RC application. I would love to get some dyno time with a nitro motor and tune to see the results but I dont have that luxury. What I do know is that the feeling of excelleration you sense when your not on the bottle and the feeling of acceleration when you are on the bottle are drastically different when driving an rc car with nitrous. From my experience the difference is about the same as a stock electric motor compared to a higher wind mod, something around the 15 turn range.
As for the super charger, there are so many threads on the internet debating the does it work or not thing that it doesnt need to be brought up here. However, I will say that there are certain factors within the engine that need to be changed to make it work more efficiently or for the lack of wording, better.
would i have to get a steel spur for my maxx? my sirio 18 has stripped spurs away(plastic) so the added tourque would need a new spur right?
There's a reason it's plastic, and there's a reason it strips. To prevent further damage to something costlier/more important like the internals of the gearbox. Plus metal on metal contact means radio interference or some nuisance that is just a pain . I'd say stay plastic, but adjust the mesh of the clutchbell and spur so that it doesn't strip.
