just now i saw a video, a supercharged s2000 with dual exhaust and it had backfire. im just wondering does the supercharger cause the backfire? or how can we make backfire on our cars? right now i have t1r 70mm single header back and k &n cold air...

 

Once question, Why would you WANT to make backfire on your car?

If your looking for the popping noise, I would suggest glasspacks for your mufflers.

 

what is glasspacks?

 

Glass packs

Get that welded on somewhere on the piping, and it will sound CRAZY literally

 

Link to vid?

My car backfires semi-often.

 

What you probably heard or saw was unburned fuel lighting off in the exhaust.

 

I'm guessing the backfire was the result of a rich mix and initial off throttle causing a lack of air and thus unburnt fuel to get through the engine and combusting on the way out.

For a stock S, I wonder if running the car rich is how you get backfires.

 

down shift rev match

 

Mine backfires nearly every time I rev-match and downshift. Otherwise, I get almost no backfire.

 

i have the invidia and sometimes when i shift i hear a pop sound and i wonder if fire came out
