Hey all how are we
live in perth and have jaguar sovereign with the 3.6L
want some more power out of it and just curious too see what people have done to get some more horses under the bonnet.
cheers

 

Remove 3.6 and install a 4.0Litre. Makes a difference!

 

Engine only got 130,000kms on it
no need for transplant yet still going strong

 

My daughter mighty 3.6 goes like stink. Now at 245K kms, and she DRIVES that damn thing as only a female can.

Twin thermo fans, so no engine drag from that huge sucker.

Trans and p/steer both cooled via external coolers, so the cooling system has less stress. No more power, just made sense at the fan time.

She runs 10W40 Nulon Synthetic in it, and that also helps.

Synthetic trans fluid sharpened up that ZF heaps.

Only 98 octane fuel.

Thats all I can recall she has done to it, but it is certainly significantly nippier than when she got it home many years ago.
