That brings up a very good idea.

Oval port intake cams and Mazda 6 exhaust cams on a boosted car.

I notice the Mazda exhaust cams are quite long winded and also should use the smaller pitch chains.

The models show them to be a good match together.


They'd be good match for NA as well if you had adjustable cam gears for the intake cams.


I wasn't too impressed with the profiles of the 6's intake cams.




Then how about this curve ball?

Jaguar S-type 3.0 VVT cams? Haven't amassed any useful cam timing information on it, only end play, journal-to-cylinder head bearing surface clearance, journal diameter runout limit and journal diameter out of round. Yet I do have lobe lift at intake and exhaust (.3688" and .3725" respectively). Much higher than the .188"/.188" found in the SVT, Escape, Taurus and 6 cams. Yet in my simulations, using the 6's durations as a reference point , I show using both Jag cams, rather than hodge-podging, produces a nice flat torque band from 4,000 to 6,000 RPM.
