Has anyone done the cooling mod on an NPI engine with the Roush (i.e., Motorsport) supercharger? I ask because the coolant circuit is somewhat different from the normal 4.6L setup. The heater supply comes from the front of the blower manifold, rather than the rear of the NPI or PI intake manifolds.

Well it's not a Whipple, it's an Eaton, and always has been. The Roush branded ones did not cost any more than the SVO branded ones.

Yes, you can drill the driver side rear flange for an additional hose barb. You can also drill the passenger side to keep your heater hose in the original location.
