The CDTi that could have been...
 
If BMW had let MGRover fit a VNT turbo

Bottom end limited for the clutch & smoke, top end limited by the small injectors

Going to have to say, Xpower grey does look stunning in the right light :drool4:

With standard gearing, i reckon it would start running out of puff at around 135 - 140mph.

Don't they start snapping cranks at that power??

No need to go over 70 though is there ;)

Wouldn't have thought so, it's the torque that would be an issue or torsional vibration. The peak torque on this is limited by the clutch and provided the DMF and crank pulley are in working order the torsional vibration wouldn't be a problem. We have these cars running 300lbft for some time now without fault.

This performed multiple loaded runs on the dyno from low end to top end. If it was going to fail it would have been then.

Plausible deniability.

As I said in the tuning group bottom end torque is shockingly bad. Would have been far better with a 320d turbo matted to a 1749 or even a hybrid 1749 that a 2256 regardless if its vnt or not running a stable boost than waiting on something much larger to boost up. I think it's great work mind you. Freelander td4 auto injectors next perhaps?
