Nah, nope. That’s just the owner being sketchy. I mean sure, if you’re talking to some retard and say you’re all motor, that’s fine. Not cheating.
Typical response by someone who has zero knowledge of nitrous, just like when big red said nitrous “sucks”.
I know of guys that have been running it on K series motors for FOUR+ years now, I’m talking 100+ shots, not some little shot. If the car is correctly set-up it will be fine and run like any other forced induction motor.
That statement is like saying when someone puts a turbocharger on their car that “yeah, it’s going to blow up sooner or later”. Sure, motors will blow up at some point due to being overly abused, but properly set-up motors with any type of power adder/forced induction will last a long time.
