I have a 05 Mach-z and have played with the idea of putting some NOS on it .
THe thing that I would like to know is that Boondockers makes a kit that comes with a add on computer that helps deal with the issues of nos
ie timing, fuel and control of the solnoids.

The NX system is a stand alone system ie" no extra computer"

Why is it better then the other and what are the + and - of a wet to a dry.

Thanks in advance.

We have found that as long as you control both the fuel and the nitrous
pressures and volumes there is no need to to alter the standard engine
tune-up. This not only makes the system NOT model specific which keep the cost down, it also allows the Nitrous to work correctly and always add the amount of power you have tuned it for.. If you do not keep the Nitrous
bottle pressure between 850 psi and 1050psi the Nitrous will not perform to its maximum no matter what you do the fuel and or timing. And as far as ignition goes we have found that aslong as your are not adding over 50 hp you do not need to worry about ignition timing.
Nitrous system are best if they are wet simply because most factory EFI
systems can not handle the INSTANT need for fuel, and most factory EFI fuel pumps dont really have the capacity to handle the fuel demands at all and soon fail completely, by using aWET nitrous kit you have a stand alone fuel system that is capable of handling all the fuel requirements for the Nitrous with out overworking the stock pump. A wet system also atomizes the fuel FINER than EFI and makes a much better combution

Again, Mike has been KooL enough to provide his experience and knowledge to our forum members, so please keep in mind we're only transfering information here for you.

Thanks Mike

Ok so far so good!

so if you have a constant temp in the bottle then the pressue will be right,between 850-1050.
So this tells me that if the pressure/temp is low then it's just the nitrous thats lean , not the fuel so there should be no engine damage if a problem with that side happens?

Am I getting this right so far??

So another couple of Q for you .

Lets say a 50hp shot on my Mach-z 1000 how long could you hold the nitrous on before damage accures, that is as long as there are no issues to start with ie it's already a good runner?

I have heard that the nitous gives the engine a sort of cooling effect is this true ??
And that the ratio for nitrous to fuel is about 1-2??

I will think of more later but this is a good start.

Thanks again.

You never go LEAN on nitrous, if the bottle pressure is it will make the
mixture RICH.

You could stay on the Nitrous untill you either run out of Nitrous (as long
as you can keep the pressure up) or you run out of room.

Yes Nitrous is the BEST intercooler ever, this one of the reasons we use
Nitrous instead of Oxygen.

The best air/fuel raio on normal motor is about 14.5 to 1
and on Nitrous it is about 12.7 to 1

Here's some information on how much nitrous it takes for duration of time used.

The amount of run time is
base on the amount of nitrous on board. It takes 2.5 lbs of nitrous to make
50 hp for a minute ( or 1.25 lbs of nitrous will make 50 hp for 30 seconds
or make 25 hp for a minute)

Cooling or freezing the bottle prior to refilling is not needed unless they are not using a refill pump.

That bottle mount is fine as long as the hose is connection on the bottle is
pointed to the rear

You might want to consider a bottle heater (#15938) to help maintain the
correct pressure which will make better power

What would be a safe compression ratio/ cranking compression for nitros on a 1/4 mile asphalt motor? Allready have the kit but don't want to use it unless it's feesable on my motor

Max recommended COLD CRANKING compression should not exceed 180lbs .

tough to answer, lots of variables, but 65 to 70 hp per cylinder should be
near the max

To get a little more into this, I am running a 1006 motor at 9800+ rpm and am looking at putting somewhere around a 25hp per cylinder shot at it but I am also hoping not to have a grenade in my hands. Running an msd so timing is easy to change. Any thoughts or advice is greatly appreciated.

25 hp would usually need nothing other a good tune up in the first place and
the the use of good fuel (105+ octane or slightly higher)

? for the nos guy. I have an 05 rev 600 carb. I bought a used boondocker system with a 40 hp shot.

1. can i run a 40 hp shot on premium fuel. or do i need to go down to a 30 hp shot. Race fuel not very convenient for me.(boon docker said ill be fine with premium with 40 hp shot.

2. How long can i hold the button down safely.

3. If i hit the button at half throttle throttle is it going to hurt any thing.

4. do i need to remove the foam in the air box next to the nos manifolds.

5. Do i need to go to a higher number plug? (br9ecs to br10ecs)

thanks for all your help.

1 If the engine has stock compression premiun fuel is ok

2 Bottle pressure is your main limiting factor, if the pressure drops too low then the maotor goes very rich and could foul plugs

3 Nitrous should only be used at WIDE OPEN, period!

4 I dont know about that, we install our nozzles on the engine side of the carbs

5 The 9 is perfect

Thanks Mike

nother ? for you.

on a boon docker system when using the barometer to set up pressureon a 05 rev. do i need to have the sled wide open for set up with air box closed to motor?

i was messing with it tonight and i was just letting it idle with the air box door open. hitting the button for about 2 seconds. i could not get real consistent pressure. It would bounce down real far. Then settle for a little bit and then just drop. it would not hold its pressure. What am i doing wrong? what do i need to do?

Thank u very much for your help.

I am sorry but I am not familiar with that type of set up, NX systems dont use a controller based on barometric pressure.

Question on compression and timing. If you are running 190-200lbs compression would there be extreme cylinder pressures with a chance to cause damages or could you run a lower HP shot of Nos and also should the timing be put back to stock. This is a strictly drag sled running C14 but I also see VP fuel has a C16 when running NOS would this fuel allow me to keep higher compression and timing? Thanks for your time.

Reply from Mike Golightly - NX POWERSPORTS

That is right at my suggested maximun compression number and C-14is the correct fuel. You should be OK, just constantly check the plugs after each run , checking closely for small shiny spots (aluminum), that means too much timing, retard about 2 degress or .5mm
