I'm not sure if this was covered in a previous thread...
Does anybody here have personal experience with both the "VX" and IPD's new turbo cam in a B230FT?
I've seen the info for the VX in the non-forced engine but my cars have turbos. What I really want to know is how the IPD turbo cam compares the the VX; torque peak, high-end breathing, gas mileage (compared to the factory "T" cam), and problems with emission testing.
The increased overlap (IPD turbo; 32? vs. VX; 18.5? vs. T; 3?) seems wrong for use with forced induction but maybe Volvo did not size the turbo too small. I am using a Garrett T3 in factory trim, not the small Mitsubishi TD04. I'd be going directly from a "T" cam to one of these on a fresh engine.
I'd also like to know whether the IPD cam runs better with a few degrees advance, like they recommend for the VX, or on the zero mark.
