[VintageLambo] Re: The 1st V 12 Jalpa ...ala Filippo Cusimano (with Chad's blessings-)

I obviously cannot sit on the sideline and just look. As you may know, I have started on my Jalpa project with the following highlights: Twin turbo chargers (Mitsubishi 3000GT turbos) Proprietary serial/parallel connection of turbos Computer controlled engine management (Electromotive TEC-3) Coils on spark plugs Custom intake manifold (with a few innovative ideas added) Port water injection (intercoolers too voluminous) Electrical water pumps (two) Thermal coating of exhaust path and cosmetic coating of various engine parts My target is an honest 350 RWHP and a flat torque curve, but the real numbers have to wait until I am finished maybe in April and truly finished with the optimization some time next summer. I am very happy with the suspension, except for the wheels, which looks good, but need to be bigger (higher gearing and better filling of the wheel wells). If I have funds left over then the car will get new (pearl white) paint as well. I had a gear-whine, which with 99% certainty is the differential and after taking the crown-wheel out and analyzed the wear pattern, I am now convinced that the meshing is inadequate and the shaft needs to be moved maybe .040" to .060". The only explanation is, that the boring of the gearbox housing got slightly out of alignment during machining. I have a plan to fix this after some further quantitative analysis. The differential gear and bearings (and I assume also the other gears) are very well proportioned, giving confidence in its ability to handle the extra power. Does anybody have experience with Jalpa differential gear noise and a way to minimize/eliminate it (beyond oil and additives)? In my opinion, the Jalpa is truly a fun, good looking and underrated car only needing more power and sticky tires. I better hurry to get ready for the unveiling of my "JR BULL" in Sant" Agata in May (just kidding).
