Default New Jaguar 3.0 supercharged v6 origin?

Hi,
I was wondering if the 3.0 is still the duratec v6 from ford with a supercharger. Or is this a fully new v6 made by Jaguar? Also what supercharger is on the new v6?
Thanks,
Mike

The new V6 is actually a development from the AJ133 V8, unrelated to the old Duratec...

The AJ126 V6 is basically an AJ133 V8 engine that has 2 less cylinders and is made on the same production line as the AJ133. It shares a very similar block as the supercharged V8 AJ133, with some unique features such as reduced bore size

The V8's use an OEM Eaton TVS R1900, so the V6 will probably run a smaller version, R1740 or R1320...

This is what I heard as well. Further to that (and I could be wrong), but I believe that the new V6 is actually the V8 with the rear 2 cylinders 'blanked off' so to speak. Or possibly they don't machine out the bores for that part of the block. Obviously then different crank and so on, but my understanding was that the starting point for the block is the same.

The AJ126 V6 block is externally the same dimensions as the AJ133 V8 block, however the casting internally is different.

There are no "blanked off cylinders" it is cast with six cylinder bores. But yes the V6 is physically the same size as the V8.

Jaguar's 3 series fighter to get the F-Type's V6?

Right, done a bit of digging, and it's true the V6 block is the same length as the V8, but it is a different block casting, with only 6 cylinder bores and a smaller bore size than the V8, so it's NOT the V8 block without 2 pistons and rods.

It's still an odd thing to do though, but it means engine bay system installations for both V6 and V8 can be similar according to someone that works at JLR, and the casting costs can be reduced in the engine plant.

That sounds about right. I didn't mean literally blanked off, like there's a plate bolted to the top or something, hence the parentheses.

It would be interesting to see where the bores are physically located in the block. My conversation with a Jag dealer technician seemed to indicate that they were offset towards the front of the block, which would make sense from a weight distribution point of view.

just possible that the blocks could be cast in the same basic molds, but internally have six bores!

but also could be machined on some of the same machineries and assembly lines.

would save a lot of development MONEY.

what else would be logical, and the finshed engine would be very robust!

That's basically what I was told, it kept development costs down and also makes it easier to package in the vehicles i.e. same engine mounts, same accessories, etc...

What's interesting there is that it's a 90 V6, as opposed to the old Duratec that's 60, which probably contributes to the tougher sound. The do sound good for a V6...

wiki says the AstonMartin 6L V12 is of 60* cylinder banks, very much akin to ford v6 duratec!

speaking about exhaust sounds.

when i was restoring my V12 XJS roadster , i wanted to hear all 12 cylinders, so i custom built an exhaust system where all 12 exit from one large diametr outlet, the sound produced after 4000 rpm is a mesmerizing whine,at 6000 its a whistling scream!

very different from a two or four outlet sound.

many guys say good reports about it, wasnt planned that way but it is what it is.

So Could that V6 be simply swapped out for a supercharged V8, like 4.0 ? Without further modifications required ? On the 2001 3.0 V6 S-Type.

No, not a chance.

If you have a V6 S-Type and want to put a V8 in it, it will be cheaper/easier to just buy a V8 S-Type.

+1

You'd have to "just" lift all the computers, wiring & sensors from the V8 as well. Plus diff etc. The car was overhauled too so various metal parts would need major changes. The list goes on.

Not the way I drive. I'm currently averaging about 19mpg on the v6. Although roads are starting to get slippery now so I will have to curtail my right foot
