bad det or just engine noise
Was driving to work this morning, car fully warm etc, and I had a bit of a blast (alongside a cbr 400/600 
), I managed to hit the rev limiter in third which resulted in some knock activity (power fc and commander), checked the commander and the knock indicator had peaked at 60!.
firstly would this be det or engine noise because the limiter was hit?
Secondly, if it would be classed as det, how bad is 60? (maximum previously had been about 21 - 22)
Cheers for any replies.

i used to get this everytime i hit the limiter, i moved the limit up form 7000 to 7300.
it solved the problem of me hitting the limiter and huge knock count without raising the limit too high.
what do you have your limit set at???

Not used to revving so high, last car was an 8v calibra so revving over 5500 was pointless.
Anyway mind is at ease now then, thought it would just be because I hit the limiter.

Are the closed deck blocks better than the open ones? and is there anyway of telling without stripping an engine if it is a closed deck block?

The closed deck block will also have it on the block.
