Hmm. 125 is pretty damned low for that E30.

I have finally been able to obtain enough information to create an appropriate conversion from crank to whp and whp to crank for this dyno.

Wheel to Crank: Multiply by 1.3267
Crank to Wheel: Multiply by 0.7538

It seemed a bit low to me too. The AFR's were a bit off, so it's definately fueling incorrectly. You'll see better when I get the chance to scan and post the dyno output sheets.

Sucks that I couldn't attend after all... My weekend plans were obliterated at the last second. I'll have to catch the next one.

Well, if this dyno is consistently showing a 25% loss, then 125 is actually about right.

That said, it was shocking how much of a difference a simply tune up made on K's iX. A new cap and rotor, plugs and a valve adjustment made a meaningful impact on both smoothness and the subjective butt dyno.

Yes! I bet you can pick up 30whp with just a tune and no boost increase.

The magic at 16:02 is incredible. (ROFL - I love how you can't even hear it accelerating.)
