Nitrous or not?
Discussion
Has anybody got any experience of nitrous injection systems fitted to their cars. I am soon to be purchasing an E28 528i and was after a bit of discreet power when required, just wondering how effective, reliable and controllable nitrous systems are in the real world, any advice would be great,

I've been dealing with these chaps:

and they seem to know their stuff. They are the only Manufacturer of NOS equipment in the UK. They did the XJS for Top Gear.
When you go for big HP increases you may want a progressive nitrous controller to blend in the feed of gas. It makes it more manageable and uses less NOS.

I bought my nitrous oxide from real steel.It cost me under £400 and i fitted it myself on to a carb, it costs between £30 and £55 for a refill depending on how much you use it.With your beema i think you would be safe usung 75bhp of nitrous with normal cast pistons without melting them.I dont use a progresive controller and ive not had any problems either. I cant say how long it will last as it depends on how much nitrous you use and depends on if your bottel it the right temp. I use 125bhp at the moment and you can feel the diffrence, just through using nitrous i can now beat my dream car over the 1/4 mile (lambogini diablo)
if you are using it for track purpose like i do its not bad to you are useing it on the street you will go through a bottel in no time whilst having fun and a big grin..

I have been told by many people that you can't get road insurance for any car fitted with nitrous, unless the bottle is removed when driving. This makes it fairly pointless unless it's a track car.
This may be wrong - I've never really investigated getting NOS - the Griff could do with more power, but the last thing it needs is more low-down torque

Don't mean to take this thread off-topic, but what are the requirements to get one of these policies and how would the cost compare with a number of separate policies on individual cars?
chris_n said:You can't get one unless you are genuinely in the motor trade, they come round to your premises to validate this (from what I've seen) cost is ITRO £2.5k (again only in my experience)

Is the reason you can't get insurance because you are more at risk of having an accident or more the dangers of having a bottle in your car?
The reason I wanted nitrous is because it seemed an affordable way of getting power for very little effort and if a was to sell the car I could rip it all out and install it again in my next car, rather than spending money on cylinder-head, schricks, exhaust etc

I have a 50hp HighPower Nitrous (NOS WIzard) system fitted to my Sylva Fury - XE and a 150hp Nitrous Oxide Systems kit fitted to my 93 LT1 Camaro.
Nitrous is safe to use if you work out how much more your engine can take and don't get greedy. The highpower kit is probably a better design than the NOS kit, due to the way that the solenoids pulse in the gas, for a BMW 528i I'd suggest using a 50bhp kit at first, seeing how it handles it and perhaps going to larger jets after you are comfortable with it. Gas Tech on 0870 735 7777 did a nice job of fitting the kit for me at a good price.
As for insurance, there is no need to tell your insurance company about this since you are not allowed to use it on the road anyway. The reason for this is that fuel must be taxed, and Nitrous is not taxed like Petrol is. You may drive around with a Nitrous kit fitted so long as it isn't armed, and the bottle switched off. Of course I would never use the nitrous whilst on the public road
For racing, you can purchase remote bottle valve opening switches so you don't have to leave the drivers seat to open the bottle. You can get electronic controllers which progressively introduce the amount and the timing of the Nitrous so as to make the system more useable.

Nitrous is cheap to buy the kit and fit it but then you have to keep filling the bottle so if you work out how many times approx you might fill it or how often then you can see how much it will reaily cost to have and i know in the end it will work out expensive..
It's not much use for track use as it wouldn't last more than a few laps. But if you've got enough power for normal use, and only want the boost for special occasions e.g. to take your road car/bike to the drag strip or Brunters then it's the best solution IMHO.
Danhay. Who said anything about using nitrous on a circuit ? If you read my first artical you will see that i was refering to a 1/4 mile which is a DRAG STRIP if you did`nt know i should have put it in big letters from the start to save any confuson. I just took it that people would take things in ! how wrong can i be ?

Drag Strip .. is that something Drag queens do...

Nitrous is not a fuel, any more than air is.

you're right, it's just an oxygen rich gaseous compound that decomposes under heat (i.e. in your engine) releasing lots of oxygen, allowing more petrol to get burnt than would otherwise be possible. That's why you plumb in both the nitrous and an extra petrol supply. >> Edited by chris_n on Wednesday 26th November 23:21
