Hot off the Dynojet drum: Ferrari 3.2qv, 9.2CR, Weber 40DCNF, Stock Microplex ignition New dyno data with the 36mm venturis, 145/F24/190/.55, stock cams: SAE Rear Wheel HP: 235.9 @6600 SAE Rear Wheel Torque: 202.7 @5600 Flywheel SAE hp (18% driveline loss): 287.6 @6600 Flywheel SAE torque (18% driveline loss): 247.2 @5600 Max uncorrected (actual today) hp: 296.3 idle A/F: starts off quite lean, but comes down to 15 A/F during 4th gear pull 13 - 14 (Ferrari Factory specs, US Mondial 3.2 with Kjet: 260 SAE hp @7000, 213 ft-lb @5500) 140 and 145 mains, while producing basically parallel A/F curves a point apart, differed in hp figures only about 1 hp. I think I have maxed out these stock emissions oriented K-jetronic cams and Microplex ignition advance with these carbs. I'm done for a while with the Webers, will now drive a bit and look at the ignition later to finish off the winter project. Super thanks to all the great folks on this board who helped, especially Mark and Philip. This has been a hoot and great fun, and I've learned a lot. best to all rt 'fuel injection is for kids'
