Hello guys I was looking around youtube for the lexus IS F and seen this mod that I have mention earlier about turbos been around the exaust system. For cars who doesn't have any space under the hood.

Here it goes for those interested I believe this can become a reality if you have the money for it.

This is the video.

I'd imagine the best change you'd have for turbocharging the W8 would be to pinch the turbos from a Bentley W12:

I would imagine that you've have a greater chance of success using a turbo system that was designed for a W-configuration engine and tight engine bays than a rear-mounted turbo system (with all the disadvantages that it entails...)

If you have ever had a look at a W12 engine thats been stripped then you will know that the design is the same as the W8 except it has 4 extra cylinders. Even looking at that photos shows you that all the ancillaries like power steering, alternator and ac pump are the same and the serpentine belt is the same. Other parts like the cam adjusters are the same as are the rear plates that cover the timing chains.

I agree that if it ever was to be done then it would be ideal to follow the W12 route, but looking at where they are located I think the chassis legs would get in the way

I think the picture above is slightly deceptive since the turbo doesn't extend laterally any further than the alternator. That said, the W12 uses a 190W liquid-cooled alternator which may be slightly larger than the one on the W8.

Size of casing of the alternator is the same I think, just the internals that are different. Looking at that pic again it's easy to see how many little things are the same between the engines. I now know what the bentley conrods part number is and when I take one of our blocks apart I'll be able to see if the conrods are yet another shared part

Here's a slightly clearer picture of the Bentley W12's turbo location:



I'd be interested to hear if the conrods are the same since, if they are, it would make me feel a bit more confident about any tweaks to the W8's output (although whether the transmission can handle it is another matter...)

While we're on the subject of bits that the W8 shares with Bentleys, here's a picture of the Arnage's brakes (and prehistoric suspension). Spot anything familiar?
