I'm in the process of fitting a WoN system to my Mk4 Golf R32 and thought i'd post a pic of my current progress and my plans.
My goal is to have a very stealthy system that would be hard to spot unless you were clued up on Nitrous Systems or R32's, any Nylon lines run in the engine bay will be Sleeved with Black Heat/Flame Resistant Sleeving to help them go un-noticed.
So far i've got the Pulsoids mounted under the Scuttle Panel with a little bracket i made... not the prettiest, but it won't be in view (thankfully VW left the mounting point for the wiper mechanism on LHD cars there for me to use
). The outlet lines have been run to the engine bay through the firewall using grommets. Heres a pic with the scuttle panel trim removed...
Fuel feed has been tee'ed into the fuel supply line... whilst i was here i also checked the fuel pressure with a calibrated gauge, which measured 3.8bar without vacuum (4.0bar fuel pressure regulator, so about right).
I've also installed all the wiring to the Pulsoids & ECU (TPS and RPM) and run it behind the dash, i've mounted a subtle looking arm switch inside the car which brings in a relay (mounted in the factory relay plate) to energise the system, the supply was picked up from an empty fuse holder in the cars manufactured fitted fuse box.
I've made some custom bottle brackets and mounted them in the spare wheel well (as R32's don't have a spare anyway) and a 5LB bottle will easily fit under the carpet, for the stealth look! The nitrous supply line is run inside the car behind trim.
I have a nitrous pressure gauge ready to go on once i recieve my bottle from NitrousOxideSupplies... i also managed to mod a BS8 CO2 bottle fitting i found to take 1/8th BSP to 5mm Enots fitting, just need to work out where/how i'm going to mount and plumb in the gauge.
At the moment i'm making a Throttle Body Spacer plate with a M10x1 tapped hole in the side to mount a single Crossfire Injector... i'll provide pics of this when it's done.
I'll be using a straight 25bhp shot for initial setup of fueling and testing, then be upping to 50bhp if everything is ok... this will be on a MSD RPM Window & TPS Switch. Eventually i plan on upping to 75bhp or maybe even 100bhp on a Progressive System of some sort, as i'm confident the 3.2 VR6 engine can take it with ease!
This is the first time i've ever played with a Nitrous System, so i'm learning as i go on, i've been lingering on these forum's for a little while gathering bits of information, and as you can see this is my first post, so go easy on me!
