Anyway, just got my car back from WON HQ yesterday They really have done a great job with my car. I was very fussy with them about the neatness of the job and they really do offer an excellent fitting service. I didn't want the car to be 'Bling Bling' afterwards, and so 'subtle' was the theme (if that's possible with Nitrous lol)
Before we get started on the details, I'd just like to say that this thread isn't intended primarily as a 'Big Up' for WON systems, what I would really like to do is educate people that are scared and ignorant about Nitrous and hopefully show you that this stuff is not to be labelled 'the killer of all engines' and fact the research and development that has been put into RELIABLE Solenoids/pulsoids and progressive controllers, is such that the delivery of Nitrous can be VERY accurately monitored and delivered.
I had no real idea what to expect when picking the car up from WON as i had never been in a car with it fitted... My impression of Nitrous was that when it was activated you would pinned back in your chair and propelled into oblivion like Clarkson driving the Ariel Atom or something .. I had all these things going round in my head about how I was going to negotiate between driving and activating and de-activating the system and whether it was going to be a clumsy and dangerous experience.... I really had no idea just how smoothly and progressively this system could actually delivered.... and with regards to arming the system, this was not at all the nerve racking experience i thought.... the system can be left on ready and easily activated with a full throttle 'kick down' as and when you want....
Over to the equipment...
Max Extreme progressive controller My link

I won't attempt to cover this completely as it has features cababilities beyond my comprehension at the moment ....I think to sum up briefly, the keys features are..... You can setup incremental power delivery for every gear, and time the delivery accuratly to within every tenth of a second ... within each gear you have 5 power level stages...after you have set your required power curve you then choose the time span of the delivery for that gear...
As you can imagine this is a little complicated at first but extremely accurate in fine tuning the system to your cars exact capabilities.
The Max will also monitor (with appropriate transducer kit fitted) your pressure from the bottle, your fuel pressure and your battery voltage.. safe parameters are then set in the controller and if your system doesn't meet the parameters, IT WILL NOT ACTIVATE!...simple as that!..... The Max also has a built in throttle position sensor and rpm monitoring, so again, you can set up the Nitrous to only deliver within the rev range that YOU specify (not a good idea to hit the rev limiter when still delivering Nitrous)... And when linked to the throttle pot sensor wiring, again, the system will only activate when at (or near) FULL throttle...
This is one of the features that really has to be experienced to be believed! When driving back from WON, I left the system on constantly, there was no flicking on and off like I thought there would be, it's all VERY controllable, you can actually drive the car quite enthusiastically without the nitrous kicking in at all, then when you press the pedal a little further ....then you feel the WON experience

The Max will also control your bottle heater too... you specify the parameters you want (950psi) and the bottle heater will kick in and out to bring the bottle up to pressure, as it will drop when delivering the Nitrous. In the cooler months of the year the bottle will be too cold for use ( mine was around 550psi this morning at 5 DegC) and so a bottle heater installed will enable better use all year round.... in fact, I would go as far as saying don't waste your time NOT fitting one, as it will be a very frustrating process trying to get up to the right psi all the time and you just won't get the same results!..

WON Pulsoids..
Here are the new X10 pulsoids
![Posted Image](http://www.pumapeople.com/stuff/1265130594/med_gallery_435_47_56255.jpg)
Wons Pulsoids are a totally unique quality and design.. They are gaurenteed for life and gaurenteed NOT to fail... In Fact, as Trev has pointed out, EVERY PIECE of WON equipment is garaunteed not to fail!...
Please note, if you buy some of the kit second hand off EBAY (as i did) the pulsoids MUST be checked and serviced before fitting so that warrenty on them (on your vehicle) is restored..
WON pulsoids (unlike generic Solenoids) are specifically designed to be pulsed to ensure that accurate, progressive control can be achieved... this is quite a complicated subject as probably best left to Trev's forum..... but is there is detailed information about the problems associated with 'pulsed' delivery (with relation to generic solenoids) on the WON forum.... check it out!
Bottle Size
Bigger is Better (for a change... Definitely worth while getting the big bottle! (11LB)...not just because it won't need filling every two minutes but also the pressure is far more consistent and will deliver more consistent performance for longer!... in fact the more bottles you can afford, the better! running a double bottle setup is also very good for producing more consistent performance too.. but ideally that means fitting two heater wraps also which can get a little pricey..
my bottle is mounted on an MDF board, then covered with a new carpet and a cutout made so only the support area sticks out...WON did a very neat fit on this..
here it is wrapped with a custom made insulator wrap designed by myself and trimmed by allon white

Nylon line + Nylon Versus braided
It's quite common to see a mixture of blue and red nylon line with WON kits. I had mine installed with Black line as I felt it looked more hidden. Also as you will see in the pictures, I asked for the Pulsoids to be mounted underneath the battery box area which does look VERY tidy and hidden away. The crossfire injector is then mounted neatly underneath the large pipe in between the airbox and inlet manifold... Don't get Trev started on Braided line...
a lot of 'other' kits do use braided hose which can be VERY un-desirable for smaller Nitrous systems (ie under 200hp ).... WON's unique spec small bore NYLON line ensures a more 'dense' flow of liquid before it tries very hard to expand....(which is exactly what happens if it travels through braided hose)..with this narrow bore pipe there is no need for purging the system, and wasting valuable Nitrous (much more on this subject on the WON forum..)
Here is the pickup from the end of the fuel rail.. no need to chop into the fuel supply line on the Puma

Jet size
Mine is currently installed with 50hp jets... with a bottle heater setup this equates to 50jet size fuel and 100 jet size Nitrous... <b> Please note! </b> without the heater wrap you may have to settle for a different ratio of fuel/nitrous as the system will stuggle to run at optimum pressure.. (950psi).. On warmer days around 25deg C the heater will not be so much of an issue!...
At the moment this setting seems more than adequate to add a huge amount of fun to the puma, and with the different delivery options on the Max, this can be very easily tweaked to be very subtle or quite aggressive, so I don't think I'll be moving up jet sizes any time soon..
My assessment of the power delivery so far is that it feels very much more like the FRS now instead of the FRP and actually when on the lower delivery settings, the power increase can be extremely smooth and subtle...
Here is an idea of power increase with the 50hp Jet size...
