Dryshot in cone filter We just set up my DynotuneNitrous dry 50-100 kit in my truck and ran the nozle dead center into the end of the cone filter. Nozzle is 90' angle spray.
Is it better be spraying straight at the MAF? It's @ 8" to the MAF from the nozzle.
Also, is there a chance of freezing up the MAF screen with that much distance?
Thx

So if my reading comprehension serves... spray it straight and descreen the MAF.
...and MAFs don't freeze...

I've been told you can just cut the deflector off the end of the 90* nozzle, but that puts you about 6-7" from the maf. Let me know how you a/f is. I have the same filter and had thought about getting a SS nozzle and extending it to about 5" from the maf.
You should have went with this.... There is a thread oin the truck section that shows how big of a difference there is from a cut off nozzle going to this. It will work better than any nozzle!!!

Adown- I'll definately let you know. Prolly gonna get it dialed in on the dyno by Slowhawk down at Dez's just to make sure it's right-n-tight. And, I like to know what the gains really are with each mod. Hopefully, I'll have graphs by the end of the week.
***EDIT***
I found the thread ND mentioned, if you're interested, it's here

It simply pokes through the filter end. The multi discharge completely fills the filter area. The lie will screw onto the end poking through.

This is the same design that makes our Halo systems so much better than a nozzle.

Came to make another thread, but saw this and figured it would be a good place to ask: (Dont know if it will be found way at the back here)
Will spraying through the MAF only, (with this type of filter nozzle) direct the MAF to send enough increased fuel to the engine? or do you still need to tap the pressure into the fuel pressure unit?
Asking because I want to put a dry system on the wifes '05 miata (no *****) and it has a return-less fuel system.
Thanks from the N2Onewbie

At first i thought the tube style dry hit would be the answer to for dry users. Still a somewhat innovative product. However, it's like the dry kits that have you put the nozzle in a certain location (usually to far away), no tuning except for going into the pcm to correct a/f. Like the guy that put it into his cone filter and ended up with a starting 10.5:1 a/f, too rich. he wants to alter his PE multiplier, not good, cause his n/a a/f to be way lean, way to much to change needed to use this method. Some start with a lean a/f, samething no way to correct this except the pcm. This is why i have been preaching the dry dual nozzle and 3 to 4 inches from MAF, you can dial in your a/f by nozzle tuning. Then you can make slight adjustments with the PE multiplier which will really not effect your n/a tune. Also, when you have the spray starting so far from the MAF, most will have a lean spike. Close to MAF the computer reacts in milla seconds and no lean spike what so ever. There is a nozzle placement thread that goes into detail on this, and I can link it if anyone wants some insight.

Thanks Robert, the link you mentioned would be some good reading if you could post it.
So basically do you have to hook up the fuel pressure switch as well? Or just spray through the MAF to trick the pcm into upping the injector duty cycle to keep up with the dry shot? Seems a little hit and miss with getting the right af ratio this way... But would be a nice simple system if it worked.
