upward trend in knock.

if i was getting true knock at 80-90 would that not be too much

If it was true knock, it would have gone pop by now

thats not too bad, but you shouldnt be getting that all the time, must be something going wrong somewhere, running lean or something

[iaint]

Could be that you\'re hitting a resonant frequency in the 2.5k-3k rev range causing spurious knock readings.

thats what i was thinking that something external was making noise. and knock was picking it up. is there any prime suspects for this.

My knock readings are around the 120 mark.:2eek
Thats on a rebuilt engine with compression readings of 8+ all round.
If you blip the throttle readings are around the 40 mark.

Carl said with readings were that high the engine would have gone pop.
That was 18 months ago and all still ok.

got 94 today just cruising along.   i didn\'t get though to mapper yet.  so i tried a little experiment. i got petrol and accelerated hard in first and second  using both turbos.  max knock was 75.  i give up trying to understand this car.
