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
- 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!
