Checking knock sensor?


Active Member
Is it possible for my t-type to be able to run 20 psi of boost on 93 octane fuel with no knock? I accidently turned the wastegate rod the wrong way while adjusting it. The scanmaster showed no knock retard and I couldn't feel it pulling any timing out nor could I hear it pinging. I then set the idle to 1800 rpm's and banged on the downpipe, valve covers and firewall, with no knock retard showing on the scanmaster. Do I just need to replace the knock sensor or is there something else to check? Thanks, R.B.
