Will stock exhaust with test pipe shoot fire or flame out?
Methanol should produce a blue flame. Blue indicates that the burn is hotter and occurring in a more oxygen-rich environment. How to produce such a flame is beyond me. I never have considered that, before.
I'd post a video but it would get removed for the racing part of it. You can clearly see my car shoot flames out of the back with just a test pipe, stock cat back and a tune. If anyone cares to look its on youtube I think. It's me and a 335i racing.....
I believe you. I am just not sure why the OP wants to shoot flames. Any potential attention from authorities is bad attention.
If you don't want the car to possibly shoot flames out of the exhaust then you should most likely just leave the car alone and drive it how it came from the factory honestly.
If your shooting flames, you must really have a **** poor tune. I installed my downpipe and test pipe, I had some back firing on decel but NO flames at all. I know this because I get followed to work every day. There's no way gas should be making it all the way to the back before blowing up. That's not normal, get a new tuner. Hearing pops and actually shooting flames are two totally different things. Usually back fires happen at the elbow of the downpipe, not your cat-back L O L.
This is wildly incorrect. I wanted to comment extensively, offering a pointed critique of the statement and then an explanation of how engines work, the impact of larger injectors, tuning, AFR, etc. There's just so much wrong here I'm not sure where to start - and so I won't.
