Backfire...

[sonichead94]

Have any of you had any backfires when launching hard? Is this bad?
Mines does it when ripping through the gears and shifting quick. But its not all the time... usually it happens when i do my first pulls of the day after that its normal.

Well his mods are in his sig... so yes. And mine backfires when No Lift Shifting alot... on shifting normal it rarely pops.. you are hearing the ignition cut so that the NLS can happen

mine did it occasionally when straight piped on gas, but it's not a backfire; it's just popping.

Yeah that's nothing, my setup is like rice crispies. It snaps, crackles, and pops all the time.

 

[sonichead94]

yea mine crackles when i slow down

 

[sonic007]

mine pops when its cold on up shifts..then quite often when im slowing down in gear

Occasionaly when my engines really cold and I shift I get a "pop" that sounds like a backfire/fuel burning out the exhaust valve.

Also occasionally get a single pop on NLS.

Letting off in gear I get a "cackle" that is most pronounced in first (like a Harley albeit different tone).

The last 2 are normal, not sure about the 1st one

it's normal sx, it's just the engine running stupid rich because it's cold.
