Standard Camshaft timing for supercharged engine?
I'm in the process of rebuilding an 18V engine for supercharging, it is rebored by 40 thou with low compression (8.3 to 1) pistons, fully balanced and a new standard camshaft with vernier adjustment,...

Graham your stock cam will position your power curve in much the same as rev range as before SC. Your SC will give you heaps of torque down low so its a mistake to change the timing looking for down...

Dennis, that is exactly the sort of informed opinion I was looking for, 6 deg it will be, taa, Graham

graham. purely FYI the cam timing moved when the chainset went from simplex to duplex. the mark on the pulley moved to advance 4 degrees. torque peak moved from 2900rpm to 2500rpm. G

Just for clarification. The Duplex timing chain and sprocket was retarded 2.5 degrees (110 degrees timing) - The simplex or single timing chain and sprocket was advanced 1.5 degrees (106 degrees...

Hi Graham, I still have my website saved but no longer publish it. I can send it to your personal e-mail in a Microsoft Word format. Ray

He's asking about camshaft timing, moving the power band up or down the rpm range as desired. In which case a supercharger cam profile will make best advantage of the supercharger and tuning with the...

OK, so I have checked the timing as explained on several sites using a DTI and am getting a reading of 117 deg, trouble is, I am now totally confused as to what I need to do to achieve whatever...

Graham Have you first established TDC with a piston stop. Turn one way then the other, in the middle is TDC. It is important to be exact. After you set the adjustment recheck it a couple of times....

Dennis, did the following: Stage 1. Established TDC using DTI to finalise position with rocking around TDC by 10 thou each way then setting up pointer on 360 deg timing wheel to 0 deg. Stage 2....

Graham at 117* your cam is retarded 7* on the OE spec. Get your cam in position wide open inlet No1 then with the adjusters loose position the crank at 110 ATDC. lock the adjusters and back up and...

I went in the workshop this morning to adjust the cam timing and just thought I would check my figures again. Doh!! 8-) I had been reading the timing wheel backwards, I was reading left to right when...
