Water injection nozzles into a Victor R - best position?
I have two water injection nozzles set for installation in an Edelbrock Victor R intake.....before I drill and tap....any suggestions on placement?
Re: Water injection nozzles into a Victor R - best position?
Ideally in a spacer above it. You want the nozzles as far from the runners as you can get to aid even distribution and atomization. If you can't run a spacer then as high as you can get them. I'm not an expert on water injecting under carbs but would think running the spray at 90 degrees to the airflow would be better than aiming it at the intake floor where it'll pool. That's what we do on EFI - jet's are aimed 90 degrees at the flow and before throttle body for best atomization. With a carby you can't go before the carb so have to go right under it. I assume you're intending a water/meth mix?
Re: Water injection nozzles into a Victor R - best position?
Certainly is a weird one.......it almost seems like the carb crowd are ignored by the meth/water injection manufacturers. The supplied jets fan at 120-degrees so if you pipe them into each side of the plenum then half of the fan is going to spray up and quite possibly puddle/pool under the Dominator.
I am now thinking of drilling from underneath and placing a single jet on the floor so the plume sprays directly up and out. Obviously this is a little more work.....
Any other thoughts?

Looks like I am the second person to go up this track......
Re: Water injection nozzles into a Victor R - best position?
Could you inject through a nitrous plate or would it not flow enough/too much? Wonder if the nitrous companies have considered something like this
Re: Water injection nozzles into a Victor R - best position?
NX have recently taken over Snow - they sell an injector plate for below the carb.....my problem is hood clearance......

Do they provide the angle of the spray cone? I am thinking you could proceed with your idea of mounting the injectors in the side of the carb mount -- emulating the plate.
Ask around if anyone has used a small disk or tab to "trim" away the conical spray pattern aimed at the carb bores. Obviously it would need to be strong enough to not vibrate loose and not so large so as to create a fuel distribution issue. Maybe you could dremel out a partial round bore with the injector proper countersunk in. That would allow you to modify the spray pattern with a minimum of flow disruption from the carb. Practice on a scrap manifold first.

^^^^^ I like it....according to google, most water/meth jets plume in a 120-degree cone - thumbs up, I'm going to give this a go.....
Re: Water injection nozzles into a Victor R - best position?
I have used the Snow water injection on a NA V8 engine, with a dual plane intake & a Victor. On both manifolds, I used two nozzles per manifold. Installed about 1" down from the carb flange, in an east-west direction. Worked well & killed the detonation.
Re: Water injection nozzles into a Victor R - best position?
Personally I would use a plate, If I had to mock up, measure and take the manifold off, then surface the spacer and if needed the carb pad to get to where it needs to be to fit. You might not need much after confirming clearance. I cant imagine you have anything stock hood wise with a Victor R under it. Looks like most nozzles are 1/8th npt, you could probably make one with a cheap AllStar 1/2 inch spacer and not have to touch anything assuming the spacer is wide enough.

Re: Water injection nozzles into a Victor R - best position?
while I agree the plate system would achieve a result, I have already milled the intake down (to get everything under the hood) so that's out of the question. NX/Snow's plate shows the injection nozzle centered and pointing directly down as opposed to 90 degrees from the flow...

Re: Water injection nozzles into a Victor R - best position?
I have always thought/wondered about, and soon will be using a water/meth injection setup on a carb using a ring/nozzle that mounts over the air filter stud with 4 injection points aiming down the venturi so that the spray is away from the air bleeds. Its probably been done but im keen to try it. I 'think' this would be good from a distribution point of view, wont know untill i try it out.

ProMeth sells a dual nozzle ring that mounts inside the air cleaner on top of the Carb.

^^^^^ not the world's most informative website that ProMeth have......any chance you can direct me to pics of the ring you mention?
