Nitrous Oxide Bottle WarmersI will give it my best shop to explain how this works. You have to understand that when most objects are heated they expand and when they are cooler they contract. On a summer's day your nitrous bottle is warm therefore producing more nitrous pressure, on a cold winters day the bottle is cold therefore the pressure drops signifigantly. Nirous Oxide is a gas stored in a pressurised bottle. Any pressurised liquid or gas is subject to change pressure with temperature. Most nitrous oxide systems are set up to run on a typical summers day which would give your nitrous oxide an approximate pressure of 800 psi. In the winter the temperature is lower therefore the pressure drops in your nitrous bottle to approx 400psi. this means when the nitrous is activated your engine would only recieve approx half of the nitrous oxide that it was designed and set-up to run effectivly but the extra fuel injected would be the same therefore making your car not run very well at all. There is two ways to overcome this problem, the first being changing your nitrous and fuel jets for the winter to allow for the colder temperatures and lower nitrous pressure. The second being a bottle warmer, a bottle warmer does what it says on the tin, it warms the nitrous bottle.... As most of you are aware that when you heat something it expands, the nitrous expands but cannot go anywhere therefore gives you more nitrous pressure, i leave my nitrous bottle warmer on until my bottle pressure reaches approx 800 psi and then i am ready to activate the nitrous. This way i can run on the same nitrous & fuel jets throughout the summer and the winter. The more bottle pressure, the more nitrous can be injected into your engine..... A good bit of advice to give to anybody is to install and test their system on a warm day and set it up with a rich fuel mixture so on a hot day you are still not running lean. Stop and think about it for a minute, it makes sense. If you install your system on a warm day and the bottle pressure is 800psi. On a hot day it could reach 1000psi or even more. So obviously on the hot day you will be firing more nitrous oxide into your engine but the additional fuel from the furl solenoid will remain the same. Therefore you have altered your mix. ALWAYS install on a warm day and run rich to compensate for the changes in weather. In winter when the bottle is cold and low pressure obviously your going to have a reverse effect as to mentioned above. I would recommend changing your nitrous solenoids jet to allow more flow to keep your power from nitrous oxide systems at optimum performance.

i think it looks mint looks to be fairly tuned so should be fast, suspension looks rather uprated so it'll fly around corners, still keeping the standardish looks though so may catch out a few of the impreza drivers

Think that looks very nice. I don't reckon the lowering will be doing the 4x4 system any good though will it?

lowering it wont effect the 4x4 system but it will handle allot better as the centre of gravity would be allot lower.....

Gotcha scoob.That does explain it perfectly.Would it not be a good idea just to cram more gas in there in the winter tho to pressurise it to 800Psi.Or would that be dangerous in the case of thermal expansion occuring when u least expect it?ie/usin ur flamer kit with ur boot open lol.

I dont know about that sorta stuff hehee.Just usin examples from the workplace.ie/gas charging at work in the tires,hydraulic systems and seat oxygen bottles.For instance, we have to charge the oxy bottles on the seats to 1800PSi no matter how cold or warm the bottle is
