Crane cam ID
Anybody have a spread sheet cross referencing Crane cam profiles to Porsche profiles? I have a pair that look like S high lift cams with "P 296" and "BP8 692" on the left and "P 296" and BP8 689 on the right side.
I called Crane (who no longer makes cams for Porsches) and a helpful tech gave me these figures. 296 I 278 E Duration numbers @ 50 262 I 244 E Valve lift max 12.09 I 11.29 E So these look to be close to a 911 S grind, or in between a DC 43 and a DC 60? |
From Dougherty's site, this looks very similar similar to a DC40:
Duration at .050" 259 intake, 242 exhaust Lift .474" intake, .440" exhaust (yours are .476" intake, .444" exhaust) |
