What should your knock be at when your are at full boost? What are bad knock readings and what are good?

The knock sensor isnt accurite from what i hear. Shits shoot the knock rating sky high...ect.



I have never knocked over 60 when actually on throttle. Thats off the stock gauge...so if its correct...i dont know..

Seems a bit high for sure. What is the knock at idle and cruise?

above 50 is not so good. either that or something is loose in your engine bay

rbrtech 09-17-2003 11:39 AM

what can cause it to be so high

We are talkign about my knock here just so every one knows. I ran 2 races last night and it never went over 78. I think that 191 was a **** up. But non the less sometimes my knock will reach 116 or so. If the stock sensor sucks i guess that coudl be it. Under norm conditions it's around 36-48.
