Tuning for Speed, Phil Irving

[xwhatsit]

So I've got a PDF document of this, the 1965 edition. If people are interested in it I could make it available somewhere, it's 20MB or so.

Is it still considered particularly relevant now? Not that the sort of engines I'm interested in are particularly advanced, still aircooled singles... but nevertheless, OHC, four valves etc. I notice a lot of the things he talks about would seem to lead to a `classic' race engine; i.e., everything concentrated into a narrow 1000rpm range of power somewhere near the redline, where the cam and the pipe align.

Is it hopelessly outdated and if so, what's the name of the book that has replaced it? Or is it still a very useful book to examine and understand?

It's still relavant to me,I still use my copy often.The stuff he talks about you won't find in modern speak at all - good old basic engineering and formulas.I haven't found anything better,and go back to his book,the Motorcycle Mechanics book that was trade issue to motorcycle apprentices,and many magazines I have kept from the '70's.Apart from that Cameron guy who writes in Cycle magazine,no one goes into much detail or depth these days.

Ill have a copy thanks
also would like two stroke performance tuning in theory
and practice

The late John Robinson tech editor of Performance Bike Magazine (before it lost the plot) i believe he wrote a couple of performance tuning books,two and four strokes.

He is in the same league as Kevin Cameron in my opinion as they both can explain technical matters in laymans terms that even a numpty like me can fathom.

There are also torrent floating around of these books. I found Robinsons's books to be so-so. Bells books or GP Blair is much better - the latter being failry heavy going. Mine are on loan at present - must get them back.

Yeah,Robinson and Bell are dated - Irving is just classic.

Have you found the 9 speed RC162 gearbox to go with that curve lol?

I uploaded it onto Scribd if anybody wants to have a looksie. It's still in copyright so it may not stay there forever, but it is out of print so it's not like anybody can whip down to the bookshop and order a copy.
