most backfires blow a filter apart or bust the intake . so out of 100 backfires u may see 10 that really do damage . but us said it
No, I've never used it.
so how would u know anything about it. oh ya u like lookin a videos that go kaboom . u do know n/a motors can go kaboom aswell. just overheat one. or let the oil pump fail.or have one have some bad detonation u will be picking up ur engine too. thats alot more common then a nitrous backfire and that destorys a engine.
i got to the track alot on weekends and ive seen 1 in the past 2 years that i can think off and it blew a quarter size hole in his intake. about a hour later he was back up and running .
