I've seen a 30bhp gain with the cam and tappets and valves and throttle body and bigger turbo , I expected more tbh but it's deff revving better than the Kent 35��I see your in Colchester that's where I am lol do you use vernier calipers to measure the tappet and adjust ? Or adjust and recheck ?ive never ran the Kent hydraulics . Always used the old genuine ford ones with no trouble to be fair . My first Kent cam lasted from 2006 to 2012 at over 300horse
