Whats the most usual causes for backfire? I was a little curious because ever since i put my downpipe on ive been having some backfire with perrrrrrrty flames out the back. Small flames yet still flames
yeah thats what i thought lol....... is that bad for my car at all? or more importantly, is it going to make it slower? and if so how do i fix it? i have an intake but I kinda rigged it to be a short ram for now, do you think i should just install all of it?
Nah install it as a short ram or dont install it at all. As for the backfires, they dont make you slower, and it's bad for the car if you are running rich, if not it's not a problem. Good for scaring the sh*t out of people.
What you're describing is technically called an "Afterfire". Caused when unignited fuel exits the exhaust valves and then ignites in the very hot exhaust piping. Not bad for the car if it isn't excessive.
I'm not sure on this but I'm just repeating what I read. The computer is reading the air being dumped back into the intake with the stock dump valve. Well putting a atmospheric BOV vents to the atmosphere and all the air that the computer thinks it's getting isn't there. So basically less air with same fuel = unignited excess fuel.
and its even more fun when you are driving down the street and you shoot a flame as you pass some little ricer kid and pulls up beside you at a stoplight and says "OMG you must be putting down mad power"
