Default Re: Burbles/Flames- harmful to motor?

Let's make a flamethrower out of the combustion chamber burning everything in sight starting with the valves/headers/cats/etc, what can go wrong. (I know you are catless).

By asking LONG TERM, you want to have fun with it and flip the car to the next owner in case something does go wrong?

Cars and coffee, here I come.

Anti lag is the only time I want to hear something similar.
Hyundai did that stock with the Veloster N - kinda cool

That, and my S54 pops and burbles a *lot* just stock with a modified exhaust. I've shot a bit of flame on high RPM upshifts with the bimmerworld street/ track exhaust.. hard to imagine how much fuel they're dumping to make it happen all the time

It's probably running a bit rich up top to do that

I greatly enjoy my SS burbling and popping from the factory. But it's a V8 and is to be expected.

I also very much do not want my S54 to sound like that, as I don't want to encourage the gremlins.

Default Re: Burbles/Flames- harmful to motor?

ive got it on mind. i went with the mildest option BuildJournal offers. i love it. but, its a weekend car that i don't daily drive so it would be a long time before i could speak on long-term effects.

i think its fine...any modification comes with risk. if you want to be 100% safe then leave it all stock, anything beyond that...you are taking risk.

Tuning isn't taking a risk. There are things that are genuinely harmful.
This essentially combusts fuel in your exhaust ports /headers instead of inside in the cylinders. This will torch your exhaust valves and jack up the temps on 1 side of ur engine head(uneven heating).
Putting aside the potential head gasket issues, if it's a catted car, this will kill the cats.
O2s, wide bands and narrow bands, wont last etc.. Not to mention that this wastes fuel... To each their own, but those are the cons.

It's not even burble, it's just makes a tin can pop. Doesn't sound cool like those open wastegate 335s. I've tried it to hear it. At the most aggressive setting it just makes a high pitch pop.

New cars have made it so lame that I want to not have it even before there's any engine damage.
