Cheers for the input, I always use Optimax, car used to be on k-jet and pinked on 95ron fuel but not Optimax. I`ve heard some garages `cutting` it wit normal unleaded and other people say it can go off (full of aditived to bump the octane up).
May have to try BP Ultima if I get knocks?
ubcnme interested to here you run 4 jets, will have to have a good look at your install, my idea was to run the water directly after the charger to give it the longest run with the air to aid chargecooling (also from charger to throttlebody is just over a foot long, air temp sensor will be just before the TB) I take it yours are after the air temp sensor and nearly a direct port system? I can see how this will prevent knock but not really aid chargcooling?
Still new to all this so if I`m talking a load of balls please tell me
Nice to here some people having go results without an i/c over 90% of people I mention water injection to seem to dismiss it as too complictated or prone to failure which gets quite annoying..
