OBJECT OF TEST. Investigation of 'knocks' on Phantom chassis. TESTER. A C. Lovesey CONDITIONS. Test bench and road. SUMMARY OF TEST. There is an audible knock on a large number of Phantom engines. It will only be a matter of time before this is complained of. The knock appears to be caused by the pistons not bei ng sufficiently flexible to allow for the expansion.
