Yesterday, Jay Kjoller and I took the six to Chris Moore, Autobahn Extremist in Avon Lake, Ohio to have it dyno'd. Newly rebuilt 2.7. A data point for you should you find it helpful:
Disp: 2.687 Bore: 90 mm Stroke: 70.4 mm Comp Ratio: 10.8:1 1966 aluminum case JE Pistons DC30/Mod. Solex (Dougherty) cams Ports: int 35 mm, exh 38mm Carbs: PMO 40 venturies 40 34 main jets 135 A/C's 185 idle jets 50 idle airs 130 E-tubes F1H DFI twin spark set at: Init 2°, 3000 25°, 8000 5° Chris measured 183HP at the wheels, so, assuming 15% loss, 210HP at engine car runs great. a good compromise for a mostly street car. I am happy. Chris has a wealth of Porsche knowledge, experience and skill. Great shop! Like Jay, a perfectionist. I would not hesitate to take a Porsche there.   |

Looks more like the acceleration tip in at 2k (most dyno operators hold steady at 2k then floor it when they hit the green button) runs a bit lean then plays catch up but then corrects as it comes up on the the main jets as he ends up in the mid 12's / low 13's for most of the run.
Can you increase the accelerator pump output on a solex? What is your base timing and your max advance? |
