Status: offline 		I have working nitrous. Have had for a while. Dont have any charts
or any BS claims. The one on the market does not impress me. Mine
is super slick in function and looks. Works off the third channel. Car
does over a hundred without it The whole supercharger/turbo/N2O
debate can be frustrating. I know all about N2O though. It is by far
the most effective way to go on glow engines. Not to say the blowers
cannot be trick, I just have the opinion its mostly show. Nothin' wrong
with that. Will send pics soon. Will market it very soon. Trying to get the
cost down for complete kits

Status: offline 		is that little carbon fiber-looking bottle with the purple ends next to the head in the picture your nitrous bottle? If so, how long a shot do you get? It cant be more than a few seconds. Also a tuning question regarding nitrous. I know that on full size engines you have to have fuel enrichment when the nitrous starts flowing to avoid a dangerous lean condition. How do you do this with r/c? I would think if you ran the needles rich enough for the nitrous, it would run like crap without it. do you use a separate fuel-enrichment circuit? I would like to know exactly how the nitrous works on your r/c setup, because nitrous adds power by adding oxygen to the combustion process, which would cause a glo-engine to go lean and blow up. How do you propose to prevent this from happening?

Status: offline 		No, that's the boost bottle. Could not help but show some of the
detail on one of the cars. Pic really had nothing to do with the
thread except for the level of workmanship. I own a laser cutting
shop and in our trade everything is measured in thousands. Its
either perfect or it gets recut. Ive been round' and round' on the
nitrous for months now, and I tend to get overly complicated about
small details. The whole fuel / N2O thing saw a bunch of re-designs
and prototypes..... I mean a bunch. I figured out that these are not
big block chevys. Basically even a lean tuned glow engine will waste
allot of fuel, so my system has no fuel boost at all. The compromise
is that you either tune it for nitrous (a little rich), or tune for just
fuel. I found that as long as you have smoke at WOT, you have
excess fuel. If you tune way lean, and do allot of top end WOT
stuff you will torch the motor with or without N2O.
Bottom line is the system is pure outlaw anyway. The girly-men
who make the rules for racers will never allow it Like any other
race mod it can be used or abused. The cool factor is a "10". Just
like full size cars, every time you push the button you also cross
your fingers and hope it will survive. Adding nitrous to nitro on a
full size car is unheard of. "BOOM". It works here though. Just use
good sense. The kid down the street used to warm up his car by
holding it in the air a revving it full blast for like 30 seconds. Haven't
seen that car for a while. Anyway.... you don't install the system
on a piece of crap car (boat, plane?). The owner has to take some
responsibility. We are still talking to companies about out sourcing
the custom valve for the system.

Status: offline 		So what you're basically saying is that the nitrous does not cause the engine to go excessively lean when you "hit the button"? I'm sure you have more experience in nitroused r/c but my experience as a 1/1 scale mechanic (and race car builder I must add) says that nitrous causes lean conditions which can explode a 1/1 scale "big block chevy" pretty easily. I still dont see how a properly tuned glo-engine could handle the extra oxygen and cylinder pressure created in a nitrous application. to handle th nitrous, you would have to be WAY rich, which would cause the engine to run like crap without the bottled horsepower. It just doesnt make sense to me.

Status: offline 		Lasershop,your car is definitly the nicest I've seen,very good work but I do not believe it does over 100 ,sorry.I work at a machine shop and we measure everything the same way,the custom valve you're talking about sourcing is the hardest part of the system as far as I can tell and thats where I'm stuck on building one.
Sledmass...a blower is a supercharger as far as I know,just a more white trash way to say it,I think you're talking about the big intake with the butterflys on it.
I'd love to see pics of a small turbo,thats where its at.No parasitic action of a drive belt and no lean or questionable fuel mixture.If they could actually be made,they'd be so expensive and I think they would need oil lines to keep the bearings working for longer than a week.maybe all the extra unburnt fuel would lube the impeller enough but I don't know.
Another thing about the compressed nitrous....if you just shot that lil charger in the intake,without a proportional valve,...whether it burnt or not the added pressure might be enough to turn the engine by itself? Do you know what PSI those chargers are?I'm wondering if you just shot compressed air in the intake,would it turn the engine?
My friend brought up the fact its a glow plug too,not a spark to ignite the nitrous so he thinks it won't work.I just don't know enough about 2-strokes and the way they're ported to teel what will and won't work.
Have fun,discuss...

Status: offline 		Here goes the debate. Ill be nice. The car does do it. The power
is incredible (without "spray"). I use the tallest pinions HPI makes.
I forget the tooth count, but they were the red ones (re anodized
purple to match the rest of the car). The spurs are custom made
aluminum 38t and 42t. That means that low gear on my car is
higher, than high gear is on the RS4ss. The flywheel is the same
diameter as the clutch bell. The rear foams are 45mm wide. Your
average 1/10 car could not get out of its own way with that
combination, yet this one will absolutely fry the tires on a hard
launch. So........ just think about the top end. This is no toy.
Its not a race car either. Jeeezz... I had slot cars that could do 100,
and that was with tires a half inch tall (ex owner of Supertracks).

As far as the nitrous.... all I can say is it works. I don't pretend to be
a scientist, but I know some stuff. To answer the first thing, it is not
gasoline (I know you know this), and it is a very small volume compared
to the real cars you modify. I run 45% nitro. That's fuel mixed with oil. These
cars do not have anywhere near the fuel metering of a pair of Holley's.
The mixture does not even have enough time or passage to completely
atomize properly. I do run it a little rich, but run like crap it doesn't. You
should try it. Bet you know some stuff too. Mr. GALAXY......what are you
talking about? An air starter like in big rigs or something? Nitrous is an
oxidizer, it does not burn or ignite on its own. It is introduced to an
atmosphere that is already on fire. Fuel of any kind needs oxygen to
burn. Its like "super oxygen". Its a chemical thing. Ya' know, atoms
and stuff. the internet is full of N2O testing for all kinds of stuff. Check
it out. As far as the glow plug goes, did you know that the fuel causes
a reaction to the platinum in the plug, and that is what keeps it glowing.
Enough for todays lesson. Keep it coming.
Ron

Status: offline 		obviously r/c engines dont have the benifit of variable fuel injection needed to boost the amount of fuel injected when n2o is injected.
if you had a separate small fuel tank which was just for nitro injection so that the n20 streem used a ventury effect to suck fuel into the n2o streem before it is injected. this would avoid compromising with rich settings and avoid another injector at the carby.
i dont kow if the pressure of the n20 and its form would alow my idea to work or not and youd need to experiment with the fuel hole size at the ventury point.
but its an idea

Status: offline 		Experimented with the tank thing. Just found it to be unnecessary.
One of the biggest problems is the lack of parts available. That
"other guy" who sells a nitrous system claims that the added exhuast
pressure, pressurizes the fuel tank and in turn forces more fuel into
the carb. I dont know about all that... maybe. Two things. I did torch
one motor because like an idiot I ran the car out of fuel. The other is
I have no yet tried any of this on any stock motors. But Ive scrapped
more motors on porting and boring projects than anything. Until you
have a big box of junk brand new motors, you dont know nuthin'.
We are really focused on marketing this. I hate to do this but until
then pics of the N2O valve are unavailable. Sorry.

Sort of off subject..... but you can check out my ultra cool guitars.

I don't know about the whole idea of nitrous, I wouldn't wanna risk ruining my motor for a little extra performance. I don't doubt that it works, just on how well it will work without ruining an engine.

Status: offline 		A wierd idea..

IS it possible to have a custom shaped "supercharged piston" which looks something like this:

\
*----
***|
***|
*|*

That little lip on the top left can CLOSE the exhaust port BEFORE the intake does, thereby allowing the supercharger to pressurize the combustion chamber. If course, balance adjustments and a host of other changes would also have to be made.

But without any modifications, the gain from forced induction wouldnt be worth it.

Nitro... I know that Nitromethane require less oxygen than Gasoline to run. So, while there would be a nice bang, Nitros Oxide would probably help Gasoline more than it would help NitroMethane.

Is it possible to Add this to a 2 stroke Zenoah gas sparker? That would make more sense to m.

PS: I ran my lawnmower with an almost 60/40 Gast/20% nitro blend yesterday.

The smell was quite strong and irritating. But.. POWER GALORE!!
The damn thing was vibrating pretty hard. I guess the crank wasnt balanced very well. Best part is.. it'll chew through any type of grass with NO effort! I'm loving this! lol


Hey LASER,

Thats some awesome stuff! Those wheels are a beaut.
I know your aware of the stuff you can do, but leme oxidise this fire and say: Custom Chassis', rims, cooling heads?!
I'm not sure how the laser works but I'm sure you could open up a nice lil custom shop for guitars and cars hehe.
And about that discount....

If you don't play with the purging too much you get 20 to thirty
seconds out of it. Don't have numbers. RPM's go up and car gets
even louder. Truth is, this particular car goes from here to there
real fast and there's not allot of time for analyzing before I run out
of room. I dont drive it that much and Im still working on the keeping
it straight part. Straight good, Crash bad
