Backfire at WOT

[Shane5425]

its not hard to make, you just need a coil pack , spark plug and a system to activate it, i can build on for under 40 bucks..

to get differant colors, aka Fast and Furious, they used propane in the exhaust system to atain differant colors

ignition circuit, just need a coil and spark plug after that... if you have a catless dp, it would work the best..

running open dp is awesome, i was getting some serious pops at wot shifts, it was badass

So is backfire at wot safe? I get it at WOT sometimes or right after shifting... and no I don't have a VTA BOV or anything to make it run extra rich. Here's a vid, you can hear it right after I shift the first time

hehe nice....most turbo cars get it with bigger exhaust

I would really like to know what backfiring does to the O2 sensors and turbo exhaust impeller... There has to be some kind of sound/pressure waves traveling back toward the engine... (huh)

I'd like to know if there are any backdraws too, anyone knows?

my friends gti does that when he lets of the gas but its more like exlosions in exhuast..a lot of them

You can get that backfire too if you're BPV/BOV is too tight ... assuming you have one of course.

 

[aaronc7]

too tight? explain lol

edit: do you mean spring inside the valve or the bolts holding it in place

 

[LBV]

Sorry, yes I mean the spring is too stiff.
