Water Injection & IC H2O Sprays

[Rusty]

I've just been trawling the forum for any threads on water injection. There are a few but they're quite old now. Has anyone played about with WI or IC sprays and if so what results/improvements have they achieved, if any? Thought it might be nice to get an updated thread going to group current knowledge.

My interest has been sparked by the marked improvement in the S2's performance in wet/damp conditions and got me thinking why I couldn't always enjoy that added zing throughout the year, especially in the summer. I hope that it would also improve the effects of any tuning that was done to the car and so be worth the effort.

lancia used intercooler spray on some of the road going evo integrales so it could be homologated for the rally cars in the early 90s,its a well proven way to reduce heat soak...
