Well i've never thought to much about the way the rev limiter on my car was set up, except for the the rpm, until the other day at an auto-x event. I tagged the limiter a few times and the fan/water-pump/alternator flew off and shredded. I put a replacement belt on thinking it was a freak thing went out for a few more runs, tagged the limiter some more and the belt came off again. It just seems weird to me that it only happens when the rev limiter is hit because it's never happened on the street and the engine will see 6k frequently. The engine in question is a m20b31.
Current settings:
spark retard/fuel cut
max retart (deg) 12
soft rev limit 7100
hard rev limit 7300
I think nando runs
fuel cut
soft rev limit 7300
hard rev limit 7400
I'm pretty sure nando tags the limiter all the time during auto-x with out issue.
Would runing fuel cut alone be better and smoother than spark retard fuel cut? Or do the soft and hard limit rpm need to be closer together?
