Two methodologies, both happy with your results.

José backs his work with warranty.
That's good enough in this case because he stands by his product.

Dougal stands by his Engjneering knowledge and that's fine too.

Just call the cat fighting quits...

"Nothing nice to say? Don't say anything"

Just sit at your keyboard, shake your head if you disagree and move on to the next thread.

And in a Vendor thread - don't hijack.

Really interesting thread, I'm intrigued to hear about the 2056 becuase I have a feeling that the Alive 'Hybrid' with billet compressor that I have fitted to my vehicle may be exactly this - does anyone know?

I'd love to get more low end kick, but fear the only way to get that right now would be to fit a turbo technics/bas VNT which would sacrifice the top end power I have now... OR to spend another 1700 quid and get the alive VNT and custom manifold.

I was reading with some keen interest a thread by a chap who fitted a supercharger to a 300TDI and found the start of a thread by someone who'd done the same to a TD5 but with no conclusion....

Obviously a supercharger would need considerable fitting/fabrication but the lure of that low down torque is mighty

You need to find an engine that stops breaking first

The alive hybrids I saw pictures of years ago had a huge compressor wheel. The od may have been around 56mm, but the intake looked significantly larger than the garrett gt2056. This is a larger trim.

The problems with a large trim wheel is surge at lower rpm and less boost due to the larger intake requiring more shaft torque and slowing down the turbine.
But yes the larger trim wheels can move more air if the engine it is bolted to has an operating range which can use it.

Superchargers do not work well on diesels. The result is low power and high fuel consumption.

Guys, this may seem like a sadly basic question, but I think you would be the ones to set me straight. So please bear with me!

What is the difference between a turbo-charger and a super-charger?

A turbocharger takes it's drive power from exhaust heat and pressure. A supercharger takes it's drive power directly from the crank.

This means a large chunk of the turbochargers drive power is otherwise wasted heat. So they can actually make an engine more efficient. It also means a (correctly sized) turbocharger scales it's operation to fit engine load.

Even in a compound setup?

Actually it was a 200TDI and not a 300TDI that was compound charged with a supercharger, see this post:
