Interesting that Dave! From what I know about water injection, I thought it was mainly to stop pre-ignition in high compression and forced induction engines. But you think it may be a benefit to a normally aspirated S-Type? I think the Rocketeer guys who are dropping the Jag AJ-V6 into Maxda MX5s are claiming ~255bhp mainly from improvements to the inlet manifold (they have 2 low profile ones for the conversion). So with this in mind I have secured a couple of spare manifolds and want to have a look at cleaning up the castings and ensuring it's all as good as can be. Plush an external polish for a bit of engine bay bling! I had bigger plans in the early days of my S-Type ownership and considered such craziness as NO2 and turbo charging. But now I just want to get her back on the road in a relatively stock form. Excepting the manifold work, Adamesh pipes and STR induction I mentioned before. I also have the rare 275/35/18 rear wheels from an STR which fill out the rear arches beautifully! I also undertake any servicing and repair using high quality OEM parts. Gone are the days where I may have thought that an amateur fettler such as myself could really improve on Jaguar engineering. Rather I want to ensure she's running as well as designed, with a little bit of help here and there to make her as dynamic as possible and best suited to my needs 🙂

You may be right Dave, with 240bph, the 3.0 has an excellent output and was pretty well thought out before leaving the factory. They're aren't a lot of 'low hanging fruit' in regards easy gains for power or efficiency (if I've overlooked any, please let me know! 😆). But I thought the Jag designed STR intake, which is a fab looking scoop affair made for 400bhp in this car, would likely draw more air than the standard 3.0 rather convoluted system, here's a pic of it: If I can't marry this up or getting running smoothly it will be easy to revert to the standard intake. I bought it from a breaker for not a great deal of money, so it's worth a try IMHO. Nothing ventured nothing gained etc. BTW, we had a discussion about just this on this forum in 2016, I can probably dig out a link or it's easy to find should anyone be interested 😉

The video decided to work today 🙂 Looked like you were taking it pretty easy Justin, guess you didn't want to blow her up or run off the road if you were driving home! Did you say you routed the air intake to inside the engine bay? This might not be the best thing, as you want as cool a charge for the engine as you can, rather than the warm engine bay air. Perhaps I misunderstood. I've secured the intake from an STR that I intend to fashion onto my 3.0 Sport manual. The std 3.0 takes air from inside the inner wing, but it goes through a hard 90° to do it, so I saw room for improvement there. After a long search I've finally found the awesome Adamesh rear silencers, so I have some nice stainless straight through rear silencers for sale if anyone wants them? They have a small stainless silencer on them, smaller than the Adamesh, and much smaller and lighter than the huge standard ones, with a nice burble on idle and a rising crescendo at high revs! 👊

The exhaust are a straight-thru with the mid silencers retained. Silent on tickover but plenty loud at high rpm. You can get these at drive in exhaust shops for £3-400 and a few hours. It's the 2.5 auto and the gears were tricky, I was thinking that if I selected the max gear to run on a straight with the 'J' gate it would be better than just using sport mode. Can't give you a rear facing camera cause I don't have one. Watch out for the tyres you use, if you look carefully at the 1st picture the rear tyre is folding over on the tread. It's Toyo's on the front and some cheapo hack on the back. They were about done so I didn't mind doing the trackday with them. Luckily I didn't have a blowout. The engine was faultless I have to say, I did about 60 laps. Everything got fairly hot but I've already done a racing conversion for the liquid cooling and it's biased to run cool. You can see the fitment of the thermostatic valve in this picture - guess the rest!

Well, it seems like you were right. I changed the battery in my wifes key fob and I've not had a warning sice. Thanks for the advice.
