NITROUS OXIDE ( nos / n2o ) advice forum

Turning the bottle on and off isn't a big deal for most of my other customers but you have the following options to overcome that;

1) Although we tell everyone NOT to leave the bottle turned on, that is just a safeguard against a Pulsoid leaking and although it is safest to do so, 99% of my customers leave the bottle on and as we've NEVER had a Pulsoid leak, nobody has ever had a problem but there is always that risk if you choose to do that.

2) We can supply the system with a Quick Action (QA) inline valve that can be mounted at the side of the drivers seat (on the floor) and then you can leave the bottle on and use the QA valve to turn the supply to the Pulsoid on and off as needed. This is obviously more convenient than turning the bottle valve on and off and it reduces the risk of leaving the bottle valve on.

3) If you wanted additional insurance against the EXTREMELY LOW risks of leaving the bottle on (with a QA valve in line), you could also add a 2nd Pulsoid, so you'd have 3 barriers against the nitrous reaching the engine unintentionally, while the bottle was turned on.



Yes that can be arranged, all you need is our turbo specific system

and an additional By-pass switch and then you can run it either way as and when you want it.


Yes that is usually the case, so instead of needing say 50 HP jets to make a 50 HP gain, you'd probably only need 25 HP jets instead, which means the nitrous will last at least twice as long on a turbo car as it does on a NA car


That's the biggest increase I've ever heard of but we have seen in excess of 100 HP achieved from just 25 HP jets. Unlike with NA motors (which we can pretty much predict what the increase will be from a given amount of nitrous), the power increase from a turbo motor depends on factors like the exhaust aspect ratio and how high the induction temps are, so we can't predict the outcome.
However, whatever engine we are supplying a system for, we ALWAYS start at no more than 25 HP jets and if you are concerned that you will make too much power from those, we can supply it with jets as low as 5 HP.


Your engine is FAR MORE LIKELY to go bang WITHOUT the nitrous than WITH IT!!!!!
The reason for that, is that on turbo alone you intake temps will be very high and as a consequence your motor is close to the point of detonation. However, nitrous boils at MINUS 128 degrees and as a consequence it REDUCES the intake temps by a HUGE amount (more nitrous more cooling) and as a consequence moves the engine AWAY from the detonation point, making it MORE RELIABLE, contrary to your expectation.


Yes and the way that is achieved is by using a boost switch (which is included in the turbo specific kits), which will switch on when the boost is below your desired boost level and then switch off above it. This switch will work in conjunction with the throttle switch, so that when you nail the throttle, the throttle switch will activate and IF the boost is below the selected level the nitrous system will activate, until the boost reaches the switch off level, which by the way could be nano seconds when the appropriate amount of nitrous is added.


You can have it so it will TOTALLY ELIMINATE that lag if you want.


You just fit a single Crossfire injector in to the intake hose just in front of the throttle body, as per these instructions;

As low as you want, as long as the engine can accelerate freely, just as is the case when driving the car as normal. The ONLY time it is detrimental to activate the nitrous system at low rpm is if (for example), you were accelerating hard and accidentally selected 5th instead of 3rd, which would overload the motor and in that situation you would be likely to damage a piston etc. when using nitrous.

The inline valve would be great

Turning the bottle off when it's in the boot hopefully in the spear wheel well would be a bit of a faf



Possibly so but the the reason you've added it to your turbo, is the same as I described as ONE of the benefits of nitrous. However, your meth system won't eliminate lag and it won't be capable of making whatever power curve you want but the nitrous system will do what the meth does (reduce the risk of det).



The bigger the turbo the bigger the lag and the greater the benefit from nitrous. If they are not using a WON system they are running a higher risk of damaging their engine and will not be making as much power as they could be, from the same amount of nitrous. However, as all the smart guys in the world and MOST people in the UK use WON systems, they are most likely to be using ours.
Is it a Time Attack car and if not what class do they race in?



There's no way of knowing that (each combo is different) but as it only takes a couple of minutes to change jets and as they only cost £12 per pair, you can quickly and cheaply work your way up until you get the result you are wanting.



NO changes will be needed.

No that will be fine.


Nitrous can do better than that.


That should surprise a few people LOL


The good thing about nitrous, especially if you only use it to eliminate lag (or up to a certain boost level), is that you WON'T make anymore PEAK power than you currently do.


Unfortunately that is like asking how long is a piece of string, there is no answer, so all I can say is that I have some customers who fill every day and others that fill every 6 months (the turbo guys always take longer between fills), as the consumption is much lower.


Thanks for that and my pleasure.
