I'm trying to dial in the clutching on my 09 M8. I was pulling the desired 8,200 RPM of the SLP performance edition package at 4,000 feet. Of course, as I accended in elevation I was pulling less RPM. Where we were climbing was 7,000 feet and I was only pulling 7,500-7,600 RPM.
So, I will be removing some weight from my clutch weights so I can reach my target RPM at the elevation we typically climb.
When I do that I will have to be careful not to put a piston through the hood at lower elevation because the sled will rev to 8,600 if I'm not careful.
That's where the shockwave that I miss badly comes in. You have an adjustment ring on your secondary. The adjustment ring raises or lowers your helix angle. So down at lower elevations you dial up a higher helix angle so your motor is loaded via a steep helix angle and as you gain elevation you can turn in the adjustment ring in lowering your helix angle and keeping your engine RPM at your target shift speed. So at 4,000 feet you can turn a 8,200 shift speed and at 10,000 feet you can turn 8,200. I sure miss not having that capability. The lower helix angle not only allows you to pull your target RPM but it also gives you a much better backshift.
Unfortunately it's NOT available for Cats that use the Diamond drive.
Is there any type of similar system that DOES work with diamond drives?
