In reply to Keith Tanner :
Yeah, the super tight belts sounded fairly awful and under the timing covers was filled with shredded belt dust. What a relief on the new water pump and belt startup when it turned over and purred.

It's alive!
Keith Tanner said:If anything, I'd expect a SM engine builder to be running less tension and thus less drag on the belt. Same reason you run undersize bearings.
If you tension it on the idler side then you get to advance the timing on the cams relative to the crank. Dunno if that adds power or not, but it's a small amount of the same effect that adjustable cam gears give you, so presumably biases it either towards torque or power?
