My Range Rover 3.9 V8 EFI on a chassis dyno. The result was a very underwhelming 23.9bhp at the wheels. Stripped the distributor and rebuilt it, and hey presto, 75bhp! Result!

  • yes - zf 4 speed auto

  • where did you find the dyno?

  • @rangie93 where are you based? That one is at Alan Jeffery's in Plymouth, which is a 1,000bhp 4WD dyno.

  • No, no typing error - it really was 23bhp. And it was dreadful to drive - top speed about 50mph and took ages to get there. yes 75bhp is a huge shortfall, but all they did was fix the distributor, there were still loads of problems. Since then i've done a top end rebuild, and I estimate it's up to about 120bhp now, but compression is about 70% of what it should be - new piston rings and I reckon I'd have the magic 180bhp.

  • 4WD dyno, nice.

  • is yours an auto?

  • I think you made an typing-error: 23hp and 75hp is a HUGE shortage on the orinal hp's.

  • dont you mean 175 bhp they have 180 standard.

  • are you sure you dont mean 175bhp, i dont get it
