I think I have seen people running 100 dry infront of the maf but someone should back me up before that is taken as the truth. I am sure I remeber 2 or 3 guys though.

40 should make a noticable differance but it won't be tire peeling power! Jump to 75 and you should be fairly happy for a wile.

I am running a dry kit in my truck wth a 75 shot after the MAF with the HSW Interface. The 75 horse jet is a .044 in mine. Just got the truck tuned ad haven't spray'd yet, but on the stock tune the 75 was a nice bit of extra power.

You can shoot a 100 dry in the truck, with out a pcm tune(but it helps). After that I would suggest in bigger injecters, tune.. After that it's time for a wet shot.. Na 40 hp isn't but maybe 25 to the wheels after the loss it takes going through the drive line. Your *** meter isn't really going to feel that

I always thought that a dry shot had to spray before the MAF, not ever after. Has something new come out?

The 1st dry kits used a piece that went inline with the fp regulator to up fuel pressure when spraying.All the Mustang NOS kits use them.

Spraying pre MAF is a pretty new idea,say10-12 years old.

For a 100 shot you should be using a .052 jet. If you are not watching airfuel you are playing with fire. On a standard dry nozzle placed before the maff something as simple as the nozzle moving a degree can alter the airfuel.

I would suggest going to one of our Halo discharge rings and do away with the nozzle. It will completely saturate the air intake flow with a more evenly spread of nitrous rather than one discharge.
