Mk VI TDI or Mini D or any other suggestions

Interesting picture of the Mini D engine, not sure why they took such a long inlet length on a turbo car

Shortly, it is all part of engine tuning.

Tuned length isn't applicable to a turbocharged inlet, especially before the turbo. Anything before the turbo is just restriction.

Sorry, but it wasn't very clear, I thought you said inlet length as the inlet manifold length. You obviously mean the turbocharger inlet, then?

[Greg Roles]

Yep, but no point having either any longer than needed.
