I think I'm going to go over to DynoLabs where I've had dyno pulls on a DynoJet, which last reported 335HP and 332 ft/lbs of Torque.
I do have "before" and "after" graphs. The before comes from March of this year, when I had the Wavetrac installed. The before, on the DynoDynamics unit, showed 305HP and 317 ft/lbs. Yesterday's pull on the DynoDynamics showed 330HP and almost 380 ft/lbs of torque. So, basically, it looks like the
new "Karmann" pulley is responsible for about 25HP and 60 ft/lbs. The "butt-dyno" definitly picked up on the additional power.
After I've gone to DynLabs and had a couple fo pulls on their DynoJet, I'll post up graphs from both the DynoJet and DynoDynamics dynomometers.
why bother? dyno is just a tool and the # doesnt mean much on the street. i dyno'd the lowest # ever on buckheads dyno at 347 rwhp. then went to the track that nite and hit the 11's. backed it up the next day in 80* heat with another 11 sec run. dont let the # fool you. its the way the # are used for tuning that counts
