Well I had I guess my first NO backfire!.....I hit it from about a 10mph roll and BOOM!!!!!!!!!!....I was like what the ******

THen my service engine soon lite came on .....so when I got home I looked at the code and it was a 34 which is the MAF...well when I popped the hood...heres what I found!..My whole air intake had blown up!..to pieces and yeah the wire in the MAF had been blown out too!......what would cause that?....I had been using it all night!

 

Purge, did you?

N2O switch set a little early?

 

Nothing a little glue wont fix.

 

Nah I didnt purge.....got it but didnt.......I have the works!...window switch set at 3000...stall on the car is 3000 so that flashes to about 3000 when I mash the gas....

what would cause that? and what is it that happened? is this whats called a NO backfire? ...Im sure glad it didnt make it into the motor??....I guess?

 

Cheers!

The only time that I had a backfire through the intake was when I hit the switch at too low RPM. With your window switch that is interesting. You experienced that at WOT and > 3K RPM?

Any other Damage? Any stains on the seat?

sounds like you had a solinoid leaking..........

what was the bottle pressure?

 

you were too low of an rpm level or you did not have the butterflies opened up enough for the n2o to flow or you had an air leak in the air boot either of these can cause this to happen

 

Maybe your fuel pressure was too low or your fuel solenoid did not open=very lean and a backfire.

My buddy blew the whole upper plenum off of his vortec 350 truck with nitrous.

 

I have seen alot of hondas taco there throtle body with NO back fires. Its funny cause it takes them a litte bit to figure it out.

 

i don't know a lot about nitrous but if you've got a 3k converter and the window switch set at 3k...would you want a window switch for a minimum speed, too? just thinking because of the fact that you're spraying at the same time that you throw the heaviest load at the motor; on launch.

 

I think I figured out what happen..tell me if this woulds cause this..

at the time this happen I mashed the gas and lit the tires up and instantly took my foot off the pedal...so Im thinking that I had the buterflys open up and did not have that much air going in and once I took my foot off the pedal..the butterflys closed and the Nitrous or extra gas had nowhere to go....so BOOM!!!!!!!

does that make sense?

 

yep BOOM!

 

yes and no.. if you have a wot switch and a rpm switch then when you let off the gas it shuts down instantly..... I have done this before and never had a problem.... I do ask again though, what was your bottle pressure...

 

bottle pressure was at about 900

 

when you say about 900 was it on the low side of 900? and what kind os systme are you running?? nx, nos, nitrous works??? I have been in your shoes before and it was a problem with bottle pressure, "which turned out to be a faulty guage" I blew mine off 3 times in one night....

 

I have NX...all the way....everything NX....all the goodies!..as far as low or high..I couldnt tell ya...Ive hit it as low as 300 and never had that problem...the more and more I think about it....I have come to the conclusion that it blew because the NO/gas had nowhere to go once I took my foot off the pedal even if everything was shut off......I guess!.....I'll find out once I get it all back together...Im just waiting to buy a MAF sensor....

anyone got an extra?

 

I had a similar thing happend to my Vett a long time ago. I turned on teh gas, the car was running like crap. I shut the bottle off adn later turned it back on with no problem,......Until I hit the throttle. KABOOM! My nitrous soleniond was leaking. I warped one head and burned 2 valves. I was using a NOS kit at the time. I now have a NX kit.

 

Did your buddy blow it up at the Evadale track?

 

i have a dual snorkel setup i could sell you if you don't have a replacement yet. no MAF though. that thing got shredded.

 

Well, yes and no. yes it shuts off instantly, but since he’s injecting in front of the TB a few inches there will be some N2O and fuel in the ducting. The way most people do this stuff (set the WOT switch to really be on about 70% or higher…) and he could have easily injected enough to make a fairly good size boom…

 

Nope the Kennedale 1/8th up here in DFW.

He put a marine intake on it, so it won't be a problem now.

 

Well there is a big problem with using N20 on a maf system because the n20 nozzle is in the air intake tube, witch is where your Maf sensor is at. The maf has a little filliment like a normal house light bulb that glows red hot and the fresh air that your enigne takes in cools that red hot filliment and the computer messures how long it take to reheat the filliment and then uses that to mesure how much air is entering your engine. My gess is that you had some sort of blockage before your TB and the n20 could not go into your engine and got all the way up to that little hot filliment and caused that bang. I might be wrong about this thoe but its just my thought lol.
