sorry my mistake ..its after the intercooler..... :yes:

being a total newbie ive been going through all the threads....few things to ask and please excuse my lack of knowledge.... :yes: ,..

i have gas coming out of bottle so i assumed that meant there was still liquid in it but from what i read thats not the case so to check i should swirl bottle and listen

my pulsoid is sitting horizontal and tie wrapped securely..should i have this mounted solid to metal.does it need to have a metal fixing for any reason

i have a nos heater but no pressure valve fitted ,as far as i can see thats not to clever either

and also i dont have my line from bottle a 100% pointing downwards

appreciate any help or recommendations to get it 100% thankyou

first off! it does not indicate that there are any useable gas in the bottle even if there is coming something out!
I had the same idear... try to pick it up and feel if its heavy..

2nd. do you have a pressure gauge? it has to have more than 900psi..
(if the pressure is low) do you have a bottle heater? low pressure low gain...

when you press the nos does the black smoke disappear?

thankyou for replying... :yes:

im guessing its just gas thats left in the bottle as i could feel the nos working when i installed the system....i have a bottle heater on but had it on without pressure gauge fitted which im guessing is not so clever...done the pedal test holding around 2500rpm and pressing micro switch ..no change ...i will check bottle for liquid..im now pretty sure thats what it is..... :yes:

The test dont always work with diesels joe...i know trev is going to point you to his book, this really is a good idea for getting your head filled with all the answers you need, my simple setup should apply to you too, bottle heater ,pressure gauge (mine is in the car) and weighting the bottle with tell you if theres nitrous in it... with the bracket and blanket still attached mine is 6.07 kilo when totally empty... ;)

A copy of my book would soon fix that for you;
http://www.noswizard.com/product_desc.php?id=97

i have gas coming out of bottle so i assumed that meant there was still liquid in it but from what i read thats not the case so to check i should swirl bottle and listen
There are only 2 ways to KNOWING FOR SURE if you have USABLE LIQUID in the bottle;
1) Watch what exits the pipe at the injection point - if you don't see a white plume that expands as it leaves the pipe it is NOT USABLE LIQUID.
2) Weigh the bottle and if it does not indicate having at least 20% of the full bottle contents it is NOT USABLE LIQUID.


my pulsoid is sitting horizontal and tie wrapped securely..should i have this mounted solid to metal.does it need to have a metal fixing for any reason
It should be securely mounted for a number of good reasons but it wont stop it working correctly as you've done it.

i have a nos heater but no pressure valve fitted ,as far as i can see thats not to clever either
It's far beyond not being clever, it's downright DANGEROUS!!!!
That won't be one of our heaters either in that case and that in itself is also dangerous, as no other heater is as highly rated as ours and that means it could go up in smoke and take your car with it.


and also i dont have my line from bottle a 100% pointing downwards
That will REDUCE the amount of nitrous that exits the bottle as LIQUID which means you are wasting more as a gas.

appreciate any help or recommendations to get it 100% thankyou
It's VERY IMPORTANT that you act on the advice I've just given you ASAP.

Glad to hear it Joe.

A gauge would be beneficial and it is supplied with the appropriate fittings, so NO additional extras required.

All bottles have 2 weights stamped in the necks;
1) The TARE weight is the empty weight
2) The GROSS weight is the full weight which is 11lbs higher than the TARE weight.

A better way to deal with it is to weigh the bottle empty and just add 11lbs to that for the full weight, as this will then account for the permanently affixed brackets and valve weights.

that sounds like the most accurate way of doing it trev...i had a look at the won videos to identify the way the nitrous should come out of solenoid ..a white colour and if its clearish its just gas i assume...also i gather its best to keep solenoid as cold/cool as possible....
sorry for all the questions...feel like a daft pest

I set up this forum to answer ALL questions, so don't be concerned about asking them, as I only have myself to blame if I'm not happy about them. ;)

All your understandings in your last post are correct
