James,
Apparently (and it kind of makes sense) that if you put the entry point for the water before the turbo you will eventually wear away the edge of the compressor wheels: water is a lot harder than air after all.
That being said you would be expecting to get better water atomisation thanks to the compressor wheel spinning at some tens of thousands of revolutions.
Me, I'd be looking at injecting it around the t/b (depends on how its set up of course: pre or post) at as an acute an angle as possible.
Wouldn't be too hard to try different places though I guess.
Regards,
Dave
At the time of writing I had forgotten about the intercooler hidden away in the front of my car
all my previous cars didn't have a one... with one of those I guess you pretty much have to go after the cooler....
But if you didn't have a cooler fitted then - where is the best entry point?
In a carby turbo you stick the carby in front of the turbo and there is all sorts of stuff (additives) in fuel.... they don't wear the wheel... if atomised correctly then water also shouldn't cause any wear?? (this has been my experience anyway)
Doesn't most of the heat get generated in the turbo - so wouldn't the best cooling come from sticking it in before it, so as to aid in cooling the turbo as well....?
Do the negatives of running it before turbo outweigh the positives of running it before turbo? (assuming no intercooler)
The reason I ask is because I know of plenty of cars that have factory intercoolers that are too small and if they just added a big pipe in place of the intercooler... and added water injection they could make more HP... ? (hopefully going to test this theory on a 32 GTST, cause the std intercoolers on those become really restrictive at anything over 14psi)
