Gen 2 on the Dyno!

[joeblowe]

Unless you test the engine by itself, you won't know the losses.
There is a difference between a 'brake dyno' and an 'inertia dyno', or drum dyno.
One should read a few more horsepower on the brake dyno - it is the horsepower available to climb a steep hill at maximum possible speed.

the last link shows the difference between the two.

Here's a couple of charts from Ivan for the "full package" versions of the GenI and Gen II. (GenI on the left GenII on the right; REAR WHEEL HP) No guarantees for exact same conditions but the dynos are likely the same . . .Both are pretty impressive with the GenII winning out on top. The full package GenII makes about 25hp more at 7k than the stocker while GenI gains are more modest. Basically, the GenI was delivered from the showroom in a much nicer state of tune. Getting the GenII where it should be does cost some $$ but it is pretty beastly when uncorked. . . .

Comparing dyno numbers from one type (for example dynojet, factory pro, fuchs) is very problematic. Almost certainly the OP's numbers are good deal higher than they would be on a dynojet unit or whatever dyno Ivan uses. The profile is interesting though and you can see the dip in the torque curve around 7k. A full exhaust would help that. . . .
