Hdi gear box advice

[Piggy]

Does anyone know what clutch to use when doing this mod. Xud or Hdi clutch?

XUD clutches hold so much more power...standard

HDi clutches soon slip with increase boost

Dose it not?? thought it would as on a motorway at 70mph with a d turbo box your doing nearly 3,000rpm, hdi box 2,500rpm surely that 500rpm less over an hour drive would save you fuel??

I think he ment doing 30mph in 5th

But you strugle to do 30mph on a hdi box in 5th will have to be in 4th at more revs useing more fuel or am I wrong?

everyone assumes the higher the gear and lower the speed the better the MPG...this simply isnt true!
