Hi Per, I have had this 'book' for some time now and thought I had posted that link before - perhaps my memory's playing tricks. Whatever, it's well worth repeating and certainly worth downloading for anyone with interest in diesel engines.
I printed it all off and had it spiral bound - an excellent reference work in a limited information arena.
I did intend to produce one of his 1.49s as a 5 cc but like a few others it has never materialised
.
Hope it gives you that 'inspiration'
