Pre-compressor water inj- is it VITAL to spray towards centre of comp wheel?

As title really? Directly at centre of comp wheel is ideal, but due to location of things that wont be possible with mine, will it be ok to still spray but not directly at it?

The jet will be will be more like 10in away, and in the direction of the airstream, but about 6in before a 45deg bend to the compressor.

Not ideal, but still workable, or?

I asked rx72c this question before and he seemed to think it would be just fine if I put the jet in the middle of this filter at this angle but I ended up going with a filter directly on the turbo instead just because I like the idea of it going directly into the turbo. Here is the setup

That's pretty much the same as my setup, and I was going to spray from the outer end of the K+N filter.

I reckon it should be ok, and I dont like the turbo im currently running anyhow so I wont shed many tears if it does wear the blades out a bit quicker than id like...

so is the jet facing the turbo? Or does this not matter since it's sucking in such a huge amount of air?

Dudemaaans car has a very fine mist so I don't think he would have a problem at all. Also xBox has an m2 nozzle so I don't think the flow would be that much meaning it wouldn't have a problem either however with an m10 nozzle that doesn't atomize the way Dudemaaaans does may have a bit of a problem at that angle but then again I could be wrong. I just wanted it spraying directly in.

The further away the jet is from the comp wheel the less the location matters.

this is a little different,, what about pre-turb ijnection on a remote mount turbo,, mounted back by rear axle.
one of my cars is a 4cyl.1.8 DIESEL coupe,, i added the remote turb with LONG pipe up to intake mani. , i have WI now up at intake of engine ,
so how (guessin is OK)would a preturb. inj. be with atomization, like drop out going around corners ETC.

any experiance here any one, hope im not off topic

Did you make your inlet pipes out of drier ducting? or something else?

turbo has a K&n mounted on the turb. inlet, under the car, back by rear axle.
long pipe up to IM on engine, is made of 2 !/4" PVC pipe sch. 40, that has three 90* corners, NO IC im wonderin if atomization would be effected on the log run up to engine, it acts like an IC somwhat.
i dont run hi boost like around 7-12psi, max., i use car as one of my daily drivers, good on fuel 45-50mpg, veggie oil, i get for free, its a cool novelty.

that said, im interested in pre-turbo inj. i guess just try it!!
