cidersurfer Posted May 26, 2008 Share Posted May 26, 2008 For Sale A pair of QED 420 cams. 2 seasons old. Vauxhall XE Camshaft Data :Q420 Description: These are mechanical profile camshafts, designed to operate at much higher speed than standard engines. These cams consequently require solid cam followers. They also require pistons with deeper valve pockets, to accommodate the higher lift. Peak Power: 215 - 225 bhp Peak Torque170-180 lbf.ft Expressed Period:285° Lift:0.418” Inlet Fully Open:100° ATDC Inlet Lift @ TDC:0.165” Exhaust Fully Open:106° BTDC Exhaust Lift @ TDC:0.125” Inlet Valve Clearance:0.006” Exhaust Valve Clearance:0.009” My car achieved 211bhp @ 6976rpm and 181lbft @ 5058rpm so it seems the power claims by QED are correct. £ 200 delivered Link to comment Share on other sites More sharing options...

cidersurfer Posted May 27, 2008 Author Share Posted May 27, 2008 Sedsy, I now have QED460V. They are a b***h on the road at low revs but on track with the revs up it's a different story. The 420 were a great compromise with over 170lbft of torque between 3500rpm and 6000rpm, I now get this between 4750rpm and 7000rpm. Link to comment Share on other sites More sharing options...
