THE H.P. OF THE AUSTIN

Our articles on Tuning the Austin Seven aroused widespread interest, and lots of queries came in afterwards. We are now able to give some further infor’nation -about the power-output of the Austin Seven. The early models, with magneto ignition and updraught Zenith carburetter, gave 10.5 b.h.p. at 2,400 r.p.m. The new horizontal Solex carburetter on the new manifold enabled the 193S engine to give 14 hit. p. at 3,500 r.p.m. We believe engines of coil ignition type but with the early induction system, were developing .about 12 b.h.p. at 2,(i00 r.p.m. With the introduction of the three-bearing engine in June, 1936, the compression-ratio was increased from 5.6 to 1 to 6 to 1 and, although no other fundamental alterations were made, the h.p. increased to 17 b.h.p. at 3,800 r.p.m. The unblown ” Ulster ” engine of 1930 gave 24 b.h.p. at 5,000 r.p.m. and the blown ” Ulster ” 33 b.h.p, at

5,000 r.p.m. This compares with 20 b.h.p. at 4,000 r.p.m. from the later ” Nippy ” and 23 b.h.p. at 4,800 r.p.m. from the “Speedy.” The “Big Seven” gave 25 b.h.p. at 4,000 r.p.m. and the new Austin Eight develops over 27 b.h.p. at 4,400 r.p.m.
