Also, I spoke briefly with Moncef at Admin Tuning about them and he seems less than pleased.
Was anything ever established with the Jun cams with any reasonable certainty as to gains? Their less aggressive cam is the same as the JWT C2 from what I've seen. I know those are what is/was in the world record car, but last I knew, the dyno was skewed due to other changes made at the same time as the cams.

Cams are not about max hp but more about power under the curve. Without the dyno graphs before and after it is really hard to say what the gains were on that engine. We can see what happened with the car from the thread. What I would want is a flat torque curve. In a boosted car, cams are useful to help spoolup the turbo's. So, you can go with a larger turbo and exhaust housing and still have the spoolup of a small turbo while keeping the upper RPM performance where a small turbo would fall off due to a restriction in the turbine and exhaust housing. We shall see how the C2's do on a turbo setup shortly.
