Doing the math, the engine mods come out to 37 HP and 39 ft.lbs. of torque on the pavement at sea level.
Dyno run was done at 6,000 ft. above sea level, 96 degrees and 11% humidity....
(3% loss of HP for each 1,000 ft. above sea level.)
(Honda quotes 12% to 15% loss between crankshaft HP and rear axel. so that would = 45.9 Crankshaft HP and 46.2 lbs. of torque at sea level...)
Cool

At the dyno this afternoon.... 6,000 feet above sea level 96 degrees F, 24.77 in-Hg, 14% humidity SAE 1.25 Red line 7,000
At the BACK TIRE....

Max HP = 31.73 @ 6,300 RPM (45.9 adjusted for elevation)
Max Torque 32.22 @ 3,500RPM (46.2 adjusted for elevation)

The published numbers for the S40 are 31 HP @ 5,400 rpm, and 37 Ft/lb at 3,400 rpm.

One of the things I find really interesting about your Dyno run - is that with the Stage 3 cam the maximum torque only shifted up 100 rpm from stock - while the maximum HP shifted up 900 rpm. This big single can still make torque down low where you need it for comfy cruising - and the better breathing from the performance cam, head work, carb and exhaust make the engine breath better so that the engine is still pulling when the stock engine is starting to run out of air.

Those of us who ride close to sea level don't appreciate what happens to your Savage up at 6,000 feet. You are running around with 18% less power than we have....and that will really be noticeable on a low HP bike like the Savage.

Probably something to do with emissions... Undecided

I really noticed this the other week on a lower power bike than the Cabbage even. I'm usually around sea level-600ft. Could feel quite a power drop at 5600ft in the mountatins and the idle speed dropped too.
