Purchased from the US BB model ,blown away by how rust free it is and the owner has a level of OCD that is rarely seen these days he is also a tool and die maker and builds the most amazing parts I have ever seen .
This car came to him with 112k miles and the motor was toast,he just looked @ a spare motor that he had which had a Eaton 45 blower on it and intercooler ,full EFI and most of the parts he made himself to a very high standard ,engineering like I have never seen before TBO.
A rebuild 411 WO case and stock bore and spec with carb cam ,running 7.5 psi boost .
Will post more when I hear more, it has completed a tuning test and first road test and really up to expectations.
Will update further ,cheers .

.No mate this guy is from the UK , he built this motor as a side project to go in a bus reading into it I think he sidelined the SC motor as would be a bit tricky pushing a bus forward...these buggers are heavy.
Someone on that forum said it wouldn't be much good in a 914 ,he politely replied it was a fun project and he built it for that reason and to test his idea's and develop his concept ..and why not if you have those skills eh .
My main reason for starting this thread was folks say you can't use forced induction on a 914 ,mcMark did it years ago and got good results with a turbo this guy has proved a SC works with clever research and the skills he has ,most of his induction system is custom made for example by him.
Cheers.

That's a bit of an inside joke around here. Someone in the 1990s wrote into the old "european car" magazine about turbocharging a 914, and the mag responded "Everybody knows you can't turbocharge a 914!" Despite MSDS (and possibly Crown?) selling kits to do just that years before...

I've never been a believer in supercharging on a 914, myself. I wonder how well that belt drive will hold up?

Tensioner for the belt is well taken care of by a custom system using an Audi spring loaded tensioner ,however there is not a lot room for the belt but he did achieve sufficent clearance in the end...rather clever setup IMO.
I was a bit skeptical but the test drive video on Youtube is impressive ,and once fully fuel mapped it will be even better ,currently running 21 degreases total advance and 7.5 PSI boost so future potential there.
Cheers.
