How much knock is unacceptable ?

[turbotaone]

Sometimes my scanmaster shows some knock, and
I was wondering at what point should I start to worry,
I mean when one,two,or three decimals are light up?

Thanks James

i'd say 4.0 and under is safe

When the second green light lights up on my knock gauge, my scanmaster usually reads about 2.0* of KR. gnttype.org suggests that anthing over 6.0* is excessive. Personally, I tune for no knock(of course you may always have transitional knock(esp. from alky)). The choice is up to you.

Depends how fast you are.

Im nearing 10's, so I aim for ZERO the whole pass. A little 2-3 shift knock is ok as long as it goes away immediatly.
