Sorry Karl, I've received nothing. Can you re-send, please?

Thanks!

Thanks Karl, that was the sort of detail I was looking for.
Those figures equate to +3.1% bhp and +4.4% torque (peak).

Joshie - can you post the AMD logs to show how the power and torque curves are improved over the entire rev range please ?

Karl, did you carry out any RR tests yourself when you developed the flywheel?

Can someone explain how a different flywheel will affect the power output of the engine ? Once it is spinning up surely it is the same - the only significant powerloss would be on the extra energy required to accelerate the heavier mass initially. I used to run lightened flywheels on my tuned up Beetles, and have never heard anyone claim they affect power output before. Acceleration, yes. They will also affect how the car performs when you hit a hill (negatively) thanks to the reduction in momentum.
I understand that they do have a noticeable affect, but not to power output. I mean, if you think of an F1 car that runs practically no fly wheel a major downside is the fact that pulling off the line they are very easy to stall, thanks to no momentum. Hence the start (pre-launch control) was so critical for the driver to get right.

The light weight flywheel has not effect what so ever on the engine output. What the flywheel does is reduce the drive line transmission power losses, thereby increasing the power at the road wheels.

I have one of theses flywheels in my S4, had it fitted with an RS4 clutch about 6 months ago, Makes alot of difference. excellent item.

Same here!! Good stuff, Karl!!

I am running with lighten pulleys as well!! [img]images/graemlins/jump_clap.gif[/img]
