Default When to add WI?

Been away from the cars for a while but back on it now and in need of a tip or two.

My 92 is running a greddy tdo4h, tubular mani, upgraded DP, FMIC, 550 RC's and a TEC, 15psi of boost. I've been running 50/50 water/meth and had it spraying from about 4psi. I have had a look on the threads to see what you guys are running and when and only found one post of 7psi?

Any tips on when it should be spraying?

Thanks

I take it you're running a simple on/off switch and not any kind of progressive controller?

I thought I read somewhere that it should be half of target boost. So if you are running 15psi, should start spraying around 7-8.

Depends entirely on how your fuel and ignition maps are tuned. If you're conservative at the lower levels and only get really aggressive near the top, then you can switch on the water later.

Thanks, yes simple on/off pressure switch. I think I'll add it up to 6-7 and see.

Thanks again
