In 1991 we organised a run of over 50 15/16" splash-fed Phoenix crankshafts (specification). This was the first batch of these cranks to be made in a sensible quantity, and the first time that relatively affordable high-quality Austin 7 crankshafts had been produced since the war. Over the last 20 years, Phoenix cranks have been fitted to virtually every high-performance Austin 7 engine and many standard ones. Their quality and reliability, derived from high-grade British forgings (stronger than machining from a billet) have ensured that they are the obvious choice for anyone rebuilding an A7 engine, from standard road-going to high performance racing specification. We can supply a Phoenix crankshaft to fit any Austin Seven (standard, sports, special and racing). They are manufactured from EN40B 'T', drop-forged, machined, balanced and nitrided. Five types are available:

  • 11/8" splash-fed: for standard cars 1923 -1928 (mostly with magneto engines).
  • 15/16" splash-fed: for standard cars 1928 -1936. Also suitable for Sports & Specials.
  • 15/16" pressure-fed: as originally fitted to Ulsters (only available by special order).
  • 11/2" splash-fed: as originally fitted to the Type 65 and Nippy (only available by special order).
  • 11/2" pressure-fed: for highly-tuned sports and racing cars as originally fitted to the Type 75 / Speedy. They can be made to fit a standard engine, which will have to be modified, e.g. by blanking off the oil jets and fitting a special nosecone (BA161pBA161p).

Phoenix make con-rods which fit both the 11/2" and 15/16" cranks. They are manufactured in EN24T, balanced, peened and fitted with ARP bolts. The 11/2" can be produced ready for white-metalling or to take Renault 4 shells; the 15/16" are ready for white-metalling. Both types are intended for use with pistons that take fully-floating gudgeon pins, e.g. C1-87C1-87.

Currently (March 2010) we only have in stock the 11/2" splash-fed and 11/2" pressure-fed cranks, and the 11/2" con-rods. We hope to have the other sizes again in June.
