The first B.III exhaust system is, of course, quite hopeless owing to the front expansion box having to be cut away to clear the suspension. We have now com-pleted tests, and a report will shortly be issued on a 3-port manifold with a double downtake and the two Jaguar systems fitted. These systems have, of course, no front expansion box. We should be glad if a design could be got out forthwith to incorporate this scheme on a B.III car. Rm.{William Robotham - Chief Engineer} | ||
