Bill,
I am a big fan of positive displacement blowers, would run one in my Track-T if it would fit under the hood. Best of both worlds, great off idle performance and a good top end. Last two NA engines I've run, 2nd to last high rpm performer, current engine is a grunt master, 516 lb/ft at just 2800 rpms. Tell me more about your ride, performance charcteristics, etc. Is that like a Whipple? Also does it have that fancy valving that allows about 1/2 hp of parasitic drag in non boost conditions? Is that a 4.6L ? BTW, we are almost neighbors, I'm just south of Placerville. This summer I'll be driving the T up to Oregon, maybe we could hook up for a burger and chat.
