i went to the track friday and i have dry nitrous i put the jet before the maf and it kept freezing it or somthing because it would die at the end of the track then start back up and i was running a 13.5 so moved it up near the throttle body and it ran a 13.2 i ran it one more time and used it like 30 feet of the line ran a 13.0 and it died but i was wondering y because it wasnt in front of the maf and when i tryed to start it i floored it and had a nitrouse backfire and granaded my intake now i was wondering if there is some reason y it stoped running other then its blown up because my intake was half gone and i drove it home and i wanna no if i will be able to put a new intake on and if anyone thinks it will be fine or it was blown up to begin with i dont wanna put it togeather to tear it apart again o btw one of my plugs were folded over idk i the piston hit it or what

HOLY RUN-ON SENTENCES BATMAN!

Sucks that happened man, your nozzle should be between the MAF and the throttle body. If your nitrous shuts off randomly that's a solenoid issue. They're probably gunked up somehow. Also how was your bottle pressure?

no the nitrous is fine the maf was freezing up and the car was getting no fuel and id wait a minute and it would fire back up

Between the cracked intake manifold and mashed spark plug it sounds like you had a sh!tty day, sorry to hear about that. Why was your nozzle mounted so far back, by the MAF? I thought the wet system nozzles were supposed to pretty much universally go just before the almost 90* turn leading to the throttle body. Regarding your question about putting on a new intake, I'm pretty sure you should be able to replace it (and spark plugs too) and be fine, but the smashed plug you had scares me a little. All you can do is try, right?

its a dry kit thats y i tryed to put it b4 the maf but it kept freezing the maf so thats y i put it after i have tht one bad plug and the one on the oposite side (both cylindars in the back) has been hit because the plugs gap was closed but idk i guess ill see what happens im gunna do a compresion test in case i leaned the motor out when the intake has gone but if thats good im gunna try a new intake and go from there i guess

holy nitrous noobs. dry kit is supposed to spray before the maf. if you don't, your going to run dangerously lean and detonate.

like i said i had it b4 the maf but it kept dieing and i got sick of having to wait or it tostart and not finishing the 1/4 but i have bigger injectors so it shouldnt of run it too lean but idk i had a back fire and granaded the intake so idk whats wrong with it or if thats the only issue

MU71L4710N

yes it will run lean if you spray a dry kit after the maf injectors don't do **** for that. the reason you spray it into the maf is so the MAF can detect a lower temperature and add more fuel (colder air is denser, meaning more air per cubic unit, so more fuel is able to be added to keep a proper AFR). nitrous is adding alot of oxygen into your engine to allow more air/fuel to combust. if your car doesn't know to add the extra fuel (spraying it onto the maf), your getting lots of air and little fuel...hence running lean and detonating. wet kits eliminate this by spraying the needed fuel into the intake tube AFTER the maf (so it doesnt add more fuel ontop of the fuel its already getting)

and its impossible to have a backfire and grenade the intake with a dry shot. so i don't know what to tell you. did this "backfire" happen to be after you sprayed the nitrous after the maf?

A dry system HAS to be installed before the MAF, if not, the computer has no way of knowing how much fuel the engine needs. Thats why you had a backfire, because it was way lean. As far as the MAF freezing up, take the screen out of it, then there is no where for ice to form & choke off the air flow.

well i had it mounted in the maf housing so it was about an inch away i should try putting it at the end of the air filter?
