Okay basically I just did a converstion to a blow-thru MAF. I want to know where to put the injection nozzle. I'm sure you can't inject before the MAF (or can you)? If you are familiar with the vortech intake elbow you will know that there is a bar dividing it into two separate sections. If I inject the alcy on one side will the alcy not be distributed properly? Can I split the line coming from the pump and put a nozzle on each side? What should I do? I know there are not many on the board with alcy injection but hopefully there are some that can help =)

Thanks.

Yes, the MAF must be before (upstream) from the water/alcoholinjection point. You are also correct - you don't want to inject on one site of the divider. So, depending on where your MAF is, you may need two nozzles.

So would I be able to simply split the line and put two nozzles one on each side? I can get pics but when I cut the elbow to fit the MAF I cut through part of the divider bar too so there is no place to put just one nozzle, I think it has to be one on each side of the elbow... So my question is can i just split it and have it work fine???

I don't see why it wouldn't work that way. My nitrous is set up similarly.

I have an smc dual alky kit on my car. I have my maf on the pressure side and I have both nozzles ~1 inch from the t/b. One nozzle on the top and the other on the bottom.

That's all I needed to know thanks!!

You cannot plumb alcohol injection into a vacuum source. The nozzle must be prior to the throttle body else will suck alcohol into the motor.

In other words, like a nitrous plate under a carb, you cant do this with alcohol unless there is a selenoid to shut off the alky.

It will be on the intake elbow directly before the air enters the TB. Thanks.

I had another question... Since the kit I got is only coming with one nozzle, and I need two, I was thinking of just buying two more replacement nozzles. I have heard about aquamist... proper size seems to be .035-.045 inches for my application. Any suggestions on nozzle brand and size???

Only thing I dont like about the aquamist nozzles is the fact you have to run rubber tubbing to the nozzles. I like using braided hoses on all my cars when it comes to handling flammable liquids.

Plus the aquamist nozzles..your starting to make this complicated and expensive..need blocks,nozzles,hoses, etc that are special..the more nozzles, the more of a chance for leaks.

Trick is to run a big nozzle and control the pump. Too much alky when the motor isnt under heavy load will slow the car down, too little will make it detonate. you have to find what it likes by trial and error.

I would suggest a single M15 nozzle. You can always punch another hole..but once you drill holes..there is no turning back.

Trick is the pump and its control..the shureflow will produce well over 150 PSI if cranked on. Keep the electronics, nozzles, stuff as simple as possible.. multiple stages = multiple headaches.
