Whilst visiting the SVR stand at Goodwood FOS I had a good look at the Full fat SRV, the Jag SVR and the new project-8

One of the SVR team explained that my Sport SVR has 550hp, the Jag SVR has around 580hp and the Project-8 has 600hp - all from the identical engine.

The question is - what was done to these engines to get them above 550hp? Anybody have the inside secrets?!?!  SVR with a few bits from Urban and Glohh

Either a remap for the ECU or a larger pulley on the S/C?? 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

2015MY Corris Grey SDv6 HSE Dynamic, the best car I have ever owned, totally reliable only a cou0le of rattles in 3 years, now no longer in my care
Also in my garage is a 1996 TDi300 Defender 90 County HT made into a fake CSW

probably a combination of pulley size, injector specs, inlet & exhaust profiles, and engine map

Also, the Jags are way lighter, so it's easier to push the engines harder without risking something breaking  --
