V-Rod Upgrade 18 October 2017

Just finished doing some repairs on the final transmission and a dyno tune on this baby.

The motor & gearbox were custom built by us to suit the high boost and is still going strong with no mechanical issues.

This time we have done some tweaks to the supercharger and air box to increase the flow and we manage to squeeze a few horsepower more out of it.

Great results as follows:

  • 237 RWHP @ 8700 rpm
  • 142 RWFt -lbs @8500 rpm (195NM) torque
  • Running 18 PSI supercharged inter-cooled forced intake (custom built inter-cooler)
  • 98 octane pump fuel.

We could reach easily 250 RWHP with bigger injectors but we decided together with the customer to leave it to this for now.

Anyone wanting to join us on a ride please contact us.
