LOL. I can tell you they don't like it worth a "F"!! I had a guy w/ a really fast slopnose that used to do that all the time. I think we built the gearbox 3 times, w/ new dog teeth, syncros and shiftsleeves each time... He didn't care, he just loved outrunning nearly everything in Huntsville... He had some huge Garret and everyother bolt-on plus a built engine w/ flamerings and Carrilos. It was laggy as hell, but dear god was it fast! One day I was driving it after routine service, without warning (no noise/vibration) a CV joint EXPLODED while I was getting on boost in 1st gear.
I kinda like the Jekly & Hyde persona of a 930 w/ turbo lag, ESPECIALLY w/ the 4 speeds. gotta love those long pulls w/ stock gearing and gobs of torque.
I don't think there is any practicality, in our case, to the turbine idea. Just a novel, genious idea I wanted everyone to see. Plus, it sounds cool!
