Anyway, thanks for the pics of the bottle setup. It's helpful and not helpful at the same time. I don't want to make a custom fuel tank, but at the same time I am still unclear where I can put a nitrous bottle. I'd like to run a 2.5lb bottle. Here is the nitrous math:

A 2.5 would probably fit very nicely in the bulkhead.

Had a stainless steel gastank with stainless straps the front of it that held the bottle. Down side was that they don't make the solenoids in alum or stainless.
It's not my ski, but I'll try to get some pics & post them up.

The tank is Aluminum and I looked into finding the solenoids and they do have them in stainless! I know where to get all of the parts for the system!

I will sell everything needed to install the system including the bottle and tank. After we rebuilt the hull and heavily reinforced it, it became too heavy to do anything on flat water even with the Nos and the ski had plenty of power in the surf without it so I haven't put it back on. You would need to modify the way the solenoids are mounted if you wanted to run it in the surf. It definitely makes power!

Nitrous?

On a two stroke?

You sure like playing with fire don't you.

So are we talking a set of billet cases finally?

How is it playing with fire? just curious... I have a spare 701 that I could mess with... if I hooked up a setup like this what kind of hp are we talking? Does the shot of nitrous relate to hp? like a 40 shot is 40hp equivalent? or what? Maybe a fun winter project... but dont want to mess with it if it's too dangerous or something...

That is exactly right. Because you a feeding the engine a set amount of air (in liquid form) it's 40hp regardless of RPM. So it's 40hp at 3000 and 40hp at 6000rpm...

But then there is the torque. Torque = hp x 5252 / rpm

So at 5252 rpm 40hp = 40 lb ft.. of torque.

At 2626 rpm 40hp = EIGHTY lb. ft. of torque. **edit for bad math**

THAT is a HUGE increase.

Wouldn't you shorten the lifespan of your engine? at which point.... Wouldn't it be better going with a higher cc engine instead for HP?
Not shooting your idea down, by all means DO IT....and please post some video with it in action....but I am merely wondering what the abuse would be on your engine......

I have no experience with NOS on a 2 stroke, but.....

Many people have the misconception the NOS destroys a motor. IT Can if improperly set up. With an increase in air, you need more fuel. This "wet setup" injects NOS as well as raw fuel when the Nos is on. Many people run a large shot and run a "dry setup" which is definate disaster for a motor.
Of course with any large HP increase comes more strain on the bottom end. There is a balance of preformance and reliabilaty on all motors. I would say most people fry motors because 1. they are running the system to dry or 2. to large a shot for what the motor can handle.

I can put a 150 shot on my stock Honda Civic but chances are my motor won't last long. However, I can run a 25-50 shot wet all day long with little effect on longjevity.

This is all very interesting. I'm anxtious to see where this goes. Could be a good thing or Bad thing. Again Like LBE stated it all depends on how it is set it up, as to how functional/practical it will be, for say the average mechanically inclined rider. Especially for a cheaper horsepower route.

The idea of power when only needed is very appealing.....specially when you do not have to spend $$crazy$$ to achieve it.

I agree, along with better fuel economy and the option to have both smooth freeride power with arm wrenching brap.

i remember there being an engine that burnt %10 nitros all the time but i can't find the thread... i thought that would be fun to build, a nitrous/methane engine like in R/C airplanes. you wouldn't have to worry about an electrical system because it is like a carbed diesel engine... the only con would be $20 a gallon fuel...

nitrious is a great thing and done correctly will not harm your motor i aint that clued up with nos on a two stroke but have had a lot of fun with it on my old drag car
if i remember corectly the bottle used on a sneaky pete setup would go under the gas tank straps not sure of the pound bottle
keep us posted

its "nitrous" not NOS. NOS is a brand of nitrous, other examples (ZEX, NX, etc) ...stop watching Fast and Furious. lol Not hating on you...just giving you an FYI so you don't bring a nitrous bottle into a race shop and say I need my "NOS tank" filled and you get sent out the door while the shop owner laughs at you.
