water injection for a twin turbo FD

[yehreally]

.....why distilled water ?
 
 

I have the huge UK rear wash bottle that holds more than 5 litres or something so the water injection lasts ages but obviously depends on how much you use it. Just remember though it has to be distilled water !!

.....why distilled water ?

I was always told it should never be tap water, the same reason for not putting tap water in the coolant.

Maybe I\'m being too paranoid.

If you want to go crazy though mix the water with Methanol, Scott (sdminus) let me feel his intake manifold after a spirited drive and it was stone cold !!!! This was in fairly warm weather and with a few other mods eg fmic, ducting for intakes etc.

be careful with meth, it can run lean top end, as I have seen one engine det that used water and meth in the WI kit where the map wasnt checked or allowed for this. Mine isnt mapped for meth incase i run out on WOT but the map is checked to make sure it doesnt run too lean at 7k plus revs

Yeah I was only talking about 5% meth.

5% meth is fine. The big single boys tend to use 50/50 mix ie Blitzboy, myself and a couple of others on here.

20 litres of distilled water from Unipart will do you for the whole year for £15

..is it true that you should use something other than plastic lines for meth as it would melt them...whats the guide for setting up ?
