Rover V8 3.9 EFI - some running issues!

I have swapped a viscous fan for an electric one in the past. It made absolutely no difference to fuel economy, and certainly didn't help cooling on hot days in traffic.......

I will be removing the air conditioning compressor, and probably the viscous fan too. I'll rebuild it and see if it still pi$$€$ coolant into the sump and compression into the radiator , if not I'll be removing the exhaust which is a bit knackered and I am thinking of fitting a Rimmer Bros stainless steel sports system. Has anyone here got any experience with these systems? Are they worth the money? £510 seems reasonable with a lifetime warranty!
Cheers everyone!

Removing the AC condenser - for repair - made a big difference to the temperature my VDP EFI runs at in heavy traffic. With it in place - but AC not working - I would regularly see the gauge read over 100C. Without it, it stays at about 90C. The condenser didn't look blocked with anything - just the usual corrosion on the ally fins.

As regards the Rimmer sports exhaust, I've had one for many a year. It's beautifully made, and I'd say has saved me quite a bit of money through not having to replace rotten bits every couple of years. It also dismantles easily if you ever need to - unlike a mild steel system.

Note, however, it is very loud which can be wearing on a long journey. And if you opt for the straight rear pipe will likely get fumes into the car. The optional cranked over to the right one sorts this.

Do Range Rover's have the same aerodynamic problems as SD1's?

Given they also have a cranked over pipe as standard I'm guessing yes.
But I'm not sure it's a 'problem' - there will always be some pressure differential when air flows over a vehicle body.

I would think so, judging by the amount of crap that splatters the rear of a Rangie when driving on wet roads.
