My dreaming on long runners was more to address the heavy car, short stroke motor, and the longer runner length for all off boost operation. I will be doing alot of stop light to stop light driving and I feel anything I can do to help off idle and low rpm torque is worth thinking about and of course letting the turbo do all the boosting power. Again just a mind excersize. If I had gone to a long stroke combination I probably would not even be thinking about it. The thing I'm not sure about (just don't understand all the physics fully yet) is the cam number versus runner length for torque. The tight 116 LCL will probably affect the runner length as will the later opening exhaust valve versus chamber filling due and how that affects the port flow at intake openning---etc etc etc--phewww. All my experience is around the N/A type cam timing etc. versus runner length etc. It may all go out the window with the drastcally different turbo specific caming numbers??? And now I see that some of the really big guns are starting to run turbo cams more near the N/A big cams as far as wider CL etc. Although the true big time power turbo combinations are after ultimate HP and do not worry aobut street manners etc, which is true to any motor combination built for full race work.
I'm wondering if anyone has any experience with the older cam combinations that the blower guys used to run back in the day. I'm guessing not far off from N/A cam timing??? Mark L
