Why so many pops? - SRT Forums

How come srt4 backfire so much? I have stg1, 3in catless dp and catback, when i hit redline the car backfires like crazy and ppl told me they saw little flames come out the exhaust. I know the hooked up turbo cars are known to pop and spit flames, but why do srt's do it so much even when decelerating? Is it because the computer is programmed to make it do it? or is it the cams and timing that makes it backfire...I kno its not really called backfire, its afterfire but i say backfire cuz it shoots out the back....so does any1 kno the answer? im not saying there's anything wrong with it, i acually love the pops, just curious on why and how it does it.

its the stage 1, these cars after-fire alot during deceleration but stage 1 pulses the injectors during deceleration so youre still getting some fuel during that time, thats what all that popping is during deceleration, i personally love it too

O ok so its basically like the fuel igniting in the exhuast track?

Yup, the injectors still fire when you let off the gas. Get a wideband air/fuel ratio gauge and you'll see what I mean...

Yeah, you'll get a second or two of fuel before it cuts...just enough for it to make some nice pops and gurgles.

yeah, its a nice sound, my friends car used to have a small leak in the o2 housing, and for some reason right around 3200rpm would shoot flames out of the exhaust tips during deceleration, gave the cops in our town something to look at when theyre tailing us...haha

The wife hates it, but Im sorry it sounds soooo nice........until someone asks you why your new car is back firing and you have to explain it to them

The average person/driver would have a heartattack driving an NSRT-4. This car emits an amazing amount of 'unusual' noises for a stock car, haha.

rolling down hill going about 35 in fourth gear is very lovely as well... it pops all the way down the hill... very nice!

but for some reason i thought it had something to do with back pressure or lack there of or some shit like that????

Your not in a honda anymore. Please stop bouncing off the rev limiter. Lol

I read on here somewhere that during deceleration once it hits 2K, the injectors turn off??

No...once you go into decel, a second or two later it'll cut. When you hit 1.5k and/or below, they'll kick back in.
