Garage Whifbitz M4 now running 740BHP!

by

Our Garage Whifbitz M4 is now running 625whp & 616lb/fto torque at the wheels, thats roughly around 740BHP at the flywheel, the latest power increase due to the removal of the secondary cat and fitting a VRSF midpipe with mapping to suit. We gained an extra 20whp from this alone!
Current mods are:
  • Turbo Dynamics Hybrid Turbos developed here at Garage Whifbitz
  • Custom Bootmod3 mapping here at Garage Whifbitz on our Dynojet rolling road
  • Downpipes
  • VRSF single midpipe
  • K&N drop in air filters
  • NGK 97506 iridium spark plugs
  • Aluminium charge pipes
  • BMW oil catch tank
  • VTT Crank hub fixture
All available to be supplied and fitted here at our workshop in South Wales, any questions just ask!
