I have a few quick questions about NoS. I am after fitting it to my 2.0L zetec (Probably a 50 shot ideally).

Now my questions are, do i require an aftermarket management system to run it? Does the ignition timing need to be retarded? Aside from using Focus RS plugs, do i require any uprated parts such as fuel pump or bigger fuel lines etc?

My mate was also telling me that you need to perform a set of cooling down procedures after using it, is this bollox? Im sure i have never heard of anything like that.

Any other useful info appreciated,

Thanks lads

 

Up

 

no you wont need any extra bits.

and ive never heard of cooling it down after nos use

 

Good idea, if you use a quality kit you will be impressed at the results i think

You can test the pump with the fanta bottle test, i dont know off hand how much spare capacity it has, but i would be shocked if it cant handle 50bhp

you shouldnt need any other changes, you wont need to retard the timing if you use a good quality kit.


After ragging any engine really hard, its advisable to have a small cooldown period IMHO, but its not any more true on nitrous than on a tuned N/A motor making the same amount of heat.


Ignore 99% of what you ever here about nitrous if its not from someone you KNOW is an expert on the subject, its not something its a good idea to take advice on from people who "kind of" know what they are talking about.

 

Cheers Chip, thats cleared everything up for me

 

If you are using a 50bhp kit and you buy one of:
NOS
ZEX
NX
etc

Be careful not to use it at low RPM or you will get det on the standard timing.



The only kit i would fit personally is a wizards of nos kit.


It delivers a smoother transmission between off gas and on gas, and this results in less isues with det.


Im not saying the other kits dont work at all, im just saying they arent the ideal choice for a 30%+ gain in power, and even less so for nearly doubling the power (like if you use it at 2500rpm to give 50bhp extra)

 

Ok cheers.

Gonna melt my 1.6 Engine with it first, should be interesting

 

If you use a wizards kit, 50bhp on a 1.6 will be fine.

Ive used wizards kits on several engines to give increases approaching 100%, and ive so far killed a total of Zero.

 

I had 75hp Nitrous Express Wet kit installed in my long gone 1.6 EFI Nova, what a f**king blast that was!!!.

I got the kit from Nemesis Performance in Essex and it was quite simple to plumb in. Didnt take long to get used to either. Car felt more responsive at high revs. It certainly gove 2.0ltr redtops and standard RS's a run for their money.

All you really need to do is be careful with any kit. This type of modification is suited for n/a and turbocharged vehicles and does not require any major modifications.

From what I can remember when Nitrous Oxide burns it produces 10 times more oxygen (i think!!! correct me if I am wrong) and with a wet kit you add the additonal petrol to enable the oxygen to be burnt rather than detonating your engine.

Basically it acts like a turbocharger. forcing more oxygen at higher pressure into the engine.

I ran a diy install nitrous express system for over a year with no detrimental problems, and I could chase anything for fun.

Remember to have a professional check over the installation if you do it yourself to make sure you aint made a mistake. I trapped the main nitrous feed on my first attempt.!!!!

Great little mod. Just dont tell the insurance!!!! or the cops!!!!!

 

I think the kit i have been offered is an NX kit.

Does this have reduced performance when compared to the wizards kit then?

 

Yes, and an increased risk of engine failure when used to add the same amount of power at low rpm.

 

air is about 1/5th oxygen
nitrous is 1/3 oxygen

not sure where the 10 times figure came from that you were given, probably someones arsehole unless they were being really clever and taking into account phasing.

 

I always used the kit at higher rpm's over 3000 i think to avoid the detonation you speak about.

Personally I have only ever used a NX kit and as I said never had a problem with it, but as with every performance upgrade you have to make sure that you dont over do it.

The 1.6 block should handle 50hp no problem as mine did but I found that when I was testing I started with 25 (bit crap), 50 hp (crap but better) and 75 hp (goes well still need more!!!)

I think I could have probably got away with a 100 hp shot of nos but I liked my daily driver and didnt want to block the block to hell.

As with everything a careful install, and proper usage the kit will last a lifetime and will give you some fun.

On a quick note BEWARE!!! The electronic solenoids that I had as part of my kit were rated for 20 sec usage at one time as they got very hot and were prone to burning out (Not just a NX failure but accross the manufacturers). So if you are buying the kit second hand make sure they are in good working order otherwise they cost Ł150 a peice I think.

 

The solenoids are the most important bit of the kit in many ways, certianly in terms of avoiding failures.

NX ones are VERY crude really, but they are still better than some.

 

i agree with chip, dont touch anythng other than a wizards kit. the competition is SHIT and they know it and even openly admit it (even if their dealers wont admit it )

 

As I said I have never tried any kit apart from Nitrous Express but I would recommend them to anyone. Alos the NX kit looks bling bling in the engine bay, as it is all braided hoses and proper fittings. like aeroquip.

 

Indeed it is mate.

Its lines designed to flow 400bhp of nitrous, then used to flow 50 instead, which results in a massive amount of un-needed phase change which results in a drop in performance and an increase in cost, due to an increase of gas consumption for the same gains as when its done properly with correctly sized lines instead.

Its fine if you want a nitrous kit for its looks though

 

It depends what application you want to use it for. If I had a n/a engine again with a nos set up I would definatly be looking at using 200+ hp as part of the fun but to be honest its up to the individual person and what they want to run.

Good luck with the NOS.

 

Even at 200bhp, the NX lines are still badly oversized, but its less of an issue than at 50bhp at least


I wouldnt ever put 200bhp into an engine in a fixed hit unless it was a V8 or similar though, so that would rule out the NX stuff really as the solenoids are crap and cant handle pulsing, same for all the kits that use generic solenoids, although you can get round it to a certain extent (if your pockets are deep enough) for adding it in "stages"
