Thanks Mike. I have a short video with sound of the final dyno pull - and the sound seems pleasing to my ears. I may be biased. I will try and get that loaded to YouTube with a link here soon. I am familiar with how the SSI's intefere with the Omega spring - like sitting close by... But these old headers wanted to fight for about 1/2 of the room the big spring occupied. No way I could knock in that 1-1/2" tube that far in, lol.
Final chapter for today:
And finally --- SHE RUNS!!! But she doesn’t idle worth a flip. In fact, it’s kind of dangerous to drive it until I can get the idle sorted out. We completed the 20 min cam break-in at 2000-2200 rpm for 20 minutes on Driven BR oil. Damn thing is kinda loud too – don’t know why ��
After the initial break-in, I hauled it to a local tuner/ dyno shop who spent that morning working on my idle, softening of the initial tip-in of the DBW pedal, and other stuff above my current pay grade. Once he was happy with that, he did about 5 pulls on the dyno and worked his way up to our self-imposed 6,500 RPM limit.
Dyno Jet calculated 251 hp at the crank – and it looked like it was still climbing. This is my first air-cooled build, and others more knowledgeable seemed pleasantly surprised. I’ll take that.
And she makes oil pressure. (Those close to me know how important that is to me due to previous self-inflicted wound last winter.)
And you may notice the tach is at zero. There’s a good reason for that. I had it pinned incorrectly in the ECM. One. Pin. Over. About 2mm away. Re-pinned and tach is back in action.
That brings us up to date. I still have some idle issues, but I’m home and have some upcoming vacation days so I’ll try and sort that out if possible. I REALLY want to put some miles on this thing!! It’s been a dead paperweight for too many months. In fact, I missed the opportunity to drive it 45 miles to Luft 11. That was a kick in the teeth. Oh well, I built it for the long haul – not just the show. I’m thinking it’ll soon be back in full action.
Best regards, Patrick
