Hi folks, thinking about going to stage 2+ with the car, only problem is that I want to run on 99 Ron fuel but we only get 95 here, I looked into additives but from what I've been reading there not worth the bottle they come in. I was thinking about water meth injection as a solution was just wondering if it was viable and how straight forward an install it is, I'm fairly handy with a spanner so fitting the tank and pump doesn't phase me it's the plumbing and wiring I'm a bit more hesitant about, anyone have any thoughts or ideas on this?
WMI is a relatively easy way of both reducing intake and cylinder temps,and upping the effective RON.
There are a number of kits around,and whilst the Aquamist is probably the best overall,it's complex,and requires some mapping.
I have an AEM kit in mine,and whilst you do need a boost pressure feed,plus power lines,it's not terribly difficult to install,but you will need a place to feed the injector into your intake piping.
I have a BSH inlet pipe which is plumbed for that,but that in turn means a bit more fiddling around to fit.
Programming it is very simple.....set it to come in at around 8psi,and to reach peak flow at peak boost,and you will also need to decide which of the injectors to use,as each has a different flow rate.
At Stg2+,you'd be looking at the small injector probably,as very high flow rates may cause ignition issues on lower powered cars.
Be sure to use 50/50 water methanol mix,or you won't get the RON benefit,and more than 50% meth tends to lose some of the cooling benefits of water.
