Couple of inches in front of
MAF is fine.

I need a clarification before I place the Alky Control Dual Nozzles.

A&A kit, cam, etc is almost done.

The picture shows the IAT in the FAST intake. The MAF is just in front of the TB. I was planning on putting the Alky dual nozzles on th 4" metal pipe down low by the intercooler.

Do I need to relocate the IAT and/or MAF to be before the Alky nozzles?

I have the 1.7 gal tank in the trunk and a hookup to put in another tank so I can have almost 3 gal.

One more thing... The kit has a 15 and a 10 nozzle. The car will be under 750 hp. There are threads saying the dual nozzles are not good for cars at that power level. Should I plug the 2nd 10 nozzle or shoot it into the air intake ahead of the supercharger?

If you're actually using the MAF for airflow calcs then Alky nozzles have to be after it. It won't read correctly with meth going through it.

Some people just use the IAT out of the MAF but otherwise run in SD, in which case spraying meth through the MAF is fine. If you're in SD mode then it's fine to spray meth through the MAF.

M10+M15 is too much. I'd just do one M15

I don't know what I am doing. I am adding a high band AEM AF but it is a stock LS2. I will be using HP Tuners.

Please make this "sesame street" clear. Right now I have the following order: IAT in intake manifold (A), MAF next in stock location (B), then Meth (C). Order is A, B, C.

I think what you are saying is that I need to move the MAF to be first, down by the intercooler, then Meth, and leave the IAT as is. Order A, C, B. This requires a wire harness extension. Thanks in advance!

It really depends on the tune, but..

Intercooler-->MAF-->Alky-->IAT

MAF needs to be in a section of straight tubing, don't get too close to the intercooler

Lexicon

Thanks for the clarification . The A&A kit couplers and pipe won't work with a relocated MAF. How are people doing this for an LS2?

The only spot with the existing hardware would be in the silicone coupler just before the TB. That is not ideal.

Arg!

Make a new pipe with a maf bung in the proper place. Then you can put the alky nozzles in the pipe rather than in a coupler.

Some people put the nozzle in the coupler, some change to card style maf setup and put IAT in intake. Some spray pre maf which is OK if tune is in speed density, i.e. Maf isn't used.

If you don't want to change the pipe then just do a SD tune.

I would swap upper pipes and mafs either way before getitng into the tuning. Go to a card style maf and put the nozzles after it, or just ditch the maf and go SD.

And yes, don't even put the 2nd nozzle in the car. There is ZERO reason, and actually it will hurt more than help to run dual nozzles at that power level.

i never understod why people bother with the maf.

so what about spraying before compressor? junk, how did that work?

Unreal

A little meth pre compressor works fine. Done a small nozzle on about 5 cars now pre turbo . Also done them preintercooler.
