Racing Beat article on ported 6-port engine
could you explain? do you mean the magazine DRAG which comes in two sizes? regular and rolling stone size? They had a good article on a ported 13b which was carbed making 200 to the flywheel dynoed. They then went fuel injection and made almost the same amount of power. Pretty good detail.
Love a copy as I was promised a fax of it which never came (can't get the mag over here
As a taster here are the carb HP results which I was emailed.
No muffler: Peak HP
Holley: 227 @ 8400
48 DHLA Dellorto: 220@7900
44 PHH Mikuni: 216 @ 8300
With muffler: Peak HP
Holley: 224 @ 8400
48 DHLA Dellorto: 211@8100
44 PHH Mikuni: 208 @ 7900
I've mislaid the IDA with EFI results, which were not as high as I would have hoped and I think were blamed on too short runners.
Also interesting is the fact that RB do ALL their dyno tuning with zero split on the timing.
