From the Britcar thread: Spec I was told: - different nozzle ends (first job) - same OEM turbo - compression side: different wheel - hot side: clip ends of turbine blades. Reduces low down torque, but increases it further up 220-240bhp < scribbly notes, may not be correct > 229 <torque basically> @ 1.9bar Website: www.jordans.nl
A bit more BKD tuning info here, http://forums.tdiclub.com/showthread.php?t=327591 Page 2 has the headling figures.
the twin cam vernier is there as diesel requires things to be spot on! I have played around with these various results still the same as all PD tuning providing it doesn't have a DPF fitted! stock BDK does come with a smaller turbo that a 1.9 130!
