Hi.

I'm in the process of fitting a serpentine 3.9 in TR7 inplace of the old vee belt 3.5 that was in there.


The part number you've listed for the serpentine belt comes up as one for a Nissan Navara on Google:

Is this the one you've used?

Lastly, I was worried about alternator clearance with the bonnet, on my old setup the alternator was low down below the water pump. Is your engine sitting further back than normal? I'm running an LT77 not a Tremac.

Thanks.

The number I quoted is stamped on the Poly V belt I used, it probably fits a number of other cars.

Alternator clearance with the bonnet is a bit of an issue. I moved the engine back 2". This is how the works rally cars were run in their final guise and helps bonnet clearance allot. The limiting factor was the bonnet catch mechanism, I would have moved it further back, but could only trim a little off the catch mechanism bracket. Not a problem on rally cars where this bracket is removed.

Unfortunately not made any progress on the car, work was pretty full on this past couple of years. Currently looking for a new job, so might have some time to finish if my next job is less demanding.
