i have been running a100 shot of nitrus for about three years, six months ago i installed a fast 78 mm intake,while racing a mustang svt the other day, something esploded in the engine bay lost all power but not the race.when iopened the hood my new intake was in three pieses and soo was the air bridge ,can t understand what went wrong:

backfire ?

[Danger731]

sounds about right

[mrr23]

what i think he is asking is how it happened.

is this a manual car?

were you hitting the rev limiter when it 'exploded'?

if not, what rpms were you at when it did 'explode'?

was it right after you let out of the throttle?

are you using a WOT switch or a push button to activate it yourself?

what mods do you have?

[Danger731]

window switch ?, fuel pressure saftey switch .... yeah the list goes on and on ...

[XKALIBER]

I think its just the fact that you have a slow car and it couldnt handle the nitrous shot... :) But at least you beat the mustang, way to keep the GM name going strong... So when are we pushing this peice of junk into the guarage? :nana:

To add to this, do you have a handheld programmer or has your car been tuned at all to up the rev limiter?

Did anything else happen beside your intake blowing off? ie- melted MAF sensor or wiring?

I also take it you have stock heads/ cam/ springs in your car.

More than likely what happened was a simple over rev, floated a valve because stock springs wont handle the higher RPMS if you upped your rev limiter and it ignited the flow of nitrous/fuel coming into your car (backfire) If you didnt blow or melt any sensors and wiring then you are lucky my friend because that is what is the biggest pain. I have hit the rev limiter a few times spraying. A couple which were pretty bad from my car kicking out of gear but it wasnt until I pushed my car a little to hard (it was tapping rev limiter before shifting into second so I upped the limiter to 6800 and didnt expect to blow second gear) that i finally got a pretty good backfire out of it. Shouldnt be anything major just make sure you take everything apart back to the intake manifold and clean it all out since it is all probrably charred to hell in there like mine was and find you a new intake :)

ps.. anyone else besides me ever backfire? Its a good learning experience :yup:

by intake do you mean the manifold??!! if so that really sucks! mine was just fine after the backfire....

[whitez28onspray]

i backedfried one time in my lt1 camaro it cost me a radiator intake plumbing MAF and AC condensor

[pizza123]

thank you for the reply guys, someone has told me that is possible that the fuel pump may not have been up to the task of supplying enough fuel and the engine leaned out .the car has abouth 370 hp to the wheels plus a 100 shoth is it possible that it leaned out?o and to that smart boy XKALIBER who is my dougther boyfriend i hope college theaches you a little spelling even i who went to school in sicily knows how to spell garage.[guarage ha ha ha ]

[juiced99ws6]

on an hundred shot that is kinda unlikely although that also depends on how well maintained your car is. you could have a clogged fuel system but the pump should have been just fine. How many miles do you have on your car?
Also what kind of nitrous kit, Wet or Dry?
And do you have a Fuel Pressure Safety Switch?

[pizza123]

yes, i do have the safety swith and the window switch the system is Nx, stock internals, 38000 thousand miles ithink that something just has to happen some times ihave no esplination just teories thank you
