How did you attach you tube to the filter once you moved the meter to the tb on the GenII? Got a pic of that?

I have been running 130-170 HP dry on stock injectors with variations in fuel pressure. I have about 10-15 lbs of nitrous through the motor every few weeks. I have never frozen the MAF due to its location (relocated to directly in front of the TB). I purposely soften the hit by running a longer inlet nitrous line for street use (most of my usage is on a street tire) and place the fan spray directly at the elbow before the MAF about 14" down stream (this keeps the MAF from freezing and seems to keep the timing from peaking too high due to the measured air density.) I typically dont see the injector spike as much in this configuration unlike when i ran the MAF and stock air box. My a/f on the wideband stays between 12.0 and 12.5 on the dynojet and 12.3-13.1 on the loaded Mustang Dyno.

hey ox, what is your maf reading? i maxed my injectors with just a 6.0, cam and cutouts. they were truely maxed too because as soon as it hit 100% duty cycle the wideband a/f ratio started ramping up fast.

i just realized that i had the wet jeted wrong for that test and i was spraying both(wet and dry) so the a/f ratio going up was my fault. i hope to get out tomorrow and do some tuning.

i did run a 12.39 gtech with a 50wet out of the hole and a 75 about 3 seconds later. that was with a dismal 2.0 60', i think i can set my window switch to hit the dry about 1sec out of the hole and get that a/f ratio down some i should pick up some ET.

going to start a thread on nitrous a/f ratio, when people say shoot for 12-1 a/f ratio with nitrous is that for best power or safety? it is starting to look like i actualy make more power being richer then i do at lets say 13.5-1.

What size jets are you using for the 170 shot?
How many nozzels are you using?
Is it on a stock motor?
How are you doing the 'variations in fuel pressure'?
Do you have any pics of your setup?

With just a 60 shot I was able to knock off a full second. Im replumbing it into a two stage dry shot and going keep bumping the size of the shot.

BigKID, I actualy went down to home depot for ideas and ended up with one of those dryer vents . The one that goes through the wall. It had a 4" tube and a flat end perfect for cutting to match the filter mount. It costed about $5 and took about 20 minutes. In all it fixed my problem I was having with the dry shot. I dont have any pics right now of it. My truck is 6000 miles away . But ill see if i have any on my computer already i can zoom in on.

got a little info to share. did some gtechs and some dyno runs.

here is a graph of NA vs 65wet



here is a graph of 65wet vs 65wet/75dry



here is a gtech of all 3 but i had 50jets in the wet not the 65's



i had the dry coming on at 3500, if i drop that to 3200 or so and run the 65's wet jets out of the hole i think i will be geting some prety good ET's, i might just keep upping that dry shot and see where it takes me(once i get a fuel pump in there)

Whats your MAF reading with the 75 dry?

na closed 36lb's 38%duty cycle
na open 38lb's 39%
65wet open 36lb's 38%
65wet/75dry open 34lb's 38%
125wet open 34lb's 36%

doesn't make alot of sence huh, i am not so sure i like the dry shot, my a/f ratio was alot more eradic with the dry on too. i need that damn turbo!!
