bike will be used for EFI calibration and exhaust system development, then we will move on to cam & big bore testing. We already have a bolt on 124" kit for the 4.5" stroke M8 motors so making power will be pretty easy at this point. We have a whole bunch of stuff that will be coming to market for the M8 bikes, we are helping a couple other companies with product as well.

Looking forward to seeing what just a good tune can do.
No shirt, no shoes, but I still get service.
Why? Girl, look at this body!

  Well look forward to seeing the results of the 124

Personally, I think the stock HP numbers are a joke! Stock engine size is pushing 2 liters and not even 100 HP at the tire. :banghead:
I am an adult?? When did that happen, and how do I make it stop?!

Jamie, a little off topic and I appologize but I notice the HP / TQ numbers are higher with the next gear (4th and 5th). I have been trying to figure out the relationship between gear ratio mchanges and dyno numbers for some time. Is there a "formula" you have noticed when this happens? For example, I have lowered my gearing to 3.16:1 for 149 HP and 145 TQ. I am wondering what the stock ratio (2011 RGU - 2.87:1) HP and TQ numbers would be. Knowing this would be helpful when researching builds from dyno sheets.

You can thank the EPA. The motor actually has a ton of potential, the primary limitation is the stock cam.

The effects the gear ratio has on an inertia dyno is entire subject in and of itself. If you start a post in the tuning/EFI section I can touch base on it.

It looks like those motors are really choked up, horsepower didn't really improve much, torque came up a bit though, a little stronger on the bottom end.

Thanks Jamie.  :up: It's started in the tuning section now.. Hopefully there will be good participation. It should be a great discussion.

Sure, but why can BMW build a 1200CC twin that does 125 HP at the crank, (probably just over 105 at the tire), and HD builds 1800 CC twin that does not break 90 HP. 1 1/2 times the CC's and less HP.
I am an adult?? When did that happen, and how do I make it stop?!

Any luck yet with preventing the ECU from noting the dyno tune if later returned to factory data? Warranty stuff.

HP is a calculated number- TQ*RPM/5252. The BMW makes peak torque about 6400 RPM, peak HP over 8000 RPM, and only makes ~75# of torque at 4K. The HD makes >50% more torque, at <1/2 the RPM.
Some folks would rather have ~110TQ at 2250, and other folks like to shift at 8K.
