Yesterday, we had the SN65 out at Finish Line Performance (Naperville, IL) for a dyno session. We made 7 runs, made a few adjustments and ended up with a max rear wheel power of 402.4 and a max rear wheel torque of 396.4. This is an increase of about 40/40 over the original factory numbers.
We found that the original plugs were not up to snuff and would randomly miss causing a 30 to 50 HP drop per incident (miss). After changing out the plugs and fine tuning the fuel curve, etc... we ended up with a much smoother operating powerplant.
It was a fun time and we are now looking to up the power to about 550 RWHP with 550 RWT. We are talking to Whipple about a blower upgrade and the expected results.
