Had a H/C swap along with 3.90 and a DTE done over the last few weeks..Racetronix and a RAM Powergrip HD yadda yadda..and had the car dyno & street tuned on and off spray ..dont recall exact numbers but some where around 544 RWFtLB TQ on spray on a mustang dyno..Bottles at 900-1000 PSI.

Builder/tuner says its pig rich and they didnt want to adjust fuel via HP tuners but to fiddle with jet sizes to fix the rich condition on spray. Jets arrive and today I goto swap them.. I take of the fuel feed line to nozzle and pull fuel jet..
size =30

Try to take the nitrous feed off and the jet holder twists out of the nozzle..no biggie.. but some backup on nozzle holder and turn the nitrous feed line off... and guess what jet pops out...SIZE 0..none..zip..zilch..nadda..no jet in there..

They/I have been spraying my car without a jet in the nozzle for about a week now? How did motor hold together? How could it be so rich with a 30 fuel jet and no nitrous jet? I traced all the feed lines and made sure im seeing what im seeing , but theres a 30 in the fuel and nothing in the Nitrous..

 

Do you by chance have the small soleniods? Some of the small soleniods and 3an line will only flow 175hp. Not that I would try it with out the jets but that is what might have saved the motor.

 

yep thats what i was gonna say.....

 

it is the small ones.. wonder what the equivalent shot was with no jets.. it did hit hard as a mother f$%&

 

Man u can't win for losing! Maybe run down to TNT and get one of their nozzles. They are probably more stout than the Zex one your running and i guarantee that it will flow better. U just don't seem to have luck with Zex!

P.S.- Nitrous still engaging right?

 

So where do you suppose that nozzle went that was on there? Hopefully not into the motor.

 

Yeah it still works.. i'm thrilled.. i had a tenhundredbajillion shot for a week.. that kicked ***..my engine didnt blow..thats cool.. then i kill joyed my self my checking the jets..only to find i didnt have one in the N side and a 30 in the F side..I ran it this afternoon with Phillip in the car with a 150 shot.. and i was disappointed.. he said it was hella fast tho in the passenger seat

 

impossible that the jet or pill as some refer to got sucked thru the nozzle and into the engine.. i think the 129 times i had my spray worked on someone dicked around with it and forgot to replace it..im gonna blame Street Modified Performance since they/he fucked everything else up on my car....... but its def not in the motor.. the top end was just off of it for H/C swap..

I must give props to 01'WS6 who finally got the wiring right and got me spraying

 

It was my pleasure! Just wish i would of checked the jets now! Figured somebody could of at least done that **** right!

 

even more strange is that i only picked up 75 HP on the dyno w no jet in the nitrous nozzle

 

Depends on exactly how rich u were actually running. But really things just aren't adding up.

 

it cant read less than 10:1 AFR. I was below that

 

It really sounds like your nitrous and fuel feed lines are swapped to the nozzle. With a 30 jet and no jet on the nitrous side would put you lean not rich. And IF it would make u rich it sure wouldn't go fat that bad! Thats insane!

 

Hey just take both jets out and please let me know what happens after a couple of runs.

I have a zex kit and my car is very rich too. I have a different year computer in my car so the tuner could increase fuel delivery. I think if I was to lean it out it would run .2 to .3 tenths quicker N/A but running rich sure gives me that warm cozy fealing when I am on the juice.

I have heard Zex kits are one of the weaker kits because they rate hp at crank not at wheels like TNT or HSW kits.

 

I don't have a ZEX system.. I have dynotune solenoids, and a Zex nozzle only.

 

I traced the lines.. its no pill in the nitrous side I'm dumbfounded as well

 

I don't remember the nozzle placement but its after the MAF right? How did the A/F look NA?

 

call me..

 

Its right before the throttle body.. rich..rich rich

 

hmm first thought on my mind was feed lines reversed (no jet in fuel). but you said you traced it. dyno it with the 150 jets and then dyno it with out!!! let me know the diff
