Rover V8, knock sensors and mechanical noise

[cinquecento]

I have a 96 Griff...however I think my question applies to any (TVR) RV8. It's a Megasquirted Griff 500 with S/C Power supercharger..and I have reduced my advance table on boost to control pinging. Aquamist water injection has helped to control the detonation...and I have just successfully installed the MS3 internal knock sensor module into my ECU..basically as an insurance policy.

How mechanically noisy is the RV8?...noise that is likely to affect the knock sensor. Interestingly, I pick up low levels of knock noise under 4000RPM ..noise that substantially increases above 4500 (definitely not pinging). Also, when I back the throttle completely off at high RPM (above 4500) there is a single, sharp knock spike.

There's a fair bit of tuning I can do on the MS, but I'm curious if the RV8 would be considered mechanically noisy?

Thanks,....At the moment I have a single knock sensor bolted to the protruding boss on the block near cylinder 1. The boss sticks out abt one inche and is abt 2 inches above the cross bolted hole that would have been drilled if the engine had been x-bolted

Thanks..frequency configured for 6.1khz and between sensing between 0-25 deg atdc.
Off for a drive today...will be interested in the datalogs.
