| To R.{Sir Henry Royce} from Hs.{Lord Ernest Hives - Chair} c. to BJ. Wcr. c. to RG.{Mr Rowledge} E.{Mr Elliott - Chief Engineer} c. to BY.{R.W. Bailey - Chief Engineer} [handwritten] X3841 Hs{Lord Ernest Hives - Chair}2/LG12.11.26. RR. FX. CLAUDEL CARBURETTERS FITTED IN THE 'V'. [handwritten and crossed out] X2934 Below is the best performance we have obtained from the engine fitted with these carburetters. The engine is the dry liner type - compression ratio 6 to 1. | REVS. | C/B.HP. | M.E.P. | PTS/HP/HR. | |---|---|---|---| | 1800 | 408 | 138 | .465 | | 1900 | 432 | 138 | .465 | | 2000 | 453 | 138 | .468 | | 2100 | 474 | 138 | .475 | | 2200 | 494 | 137 | .478 | | 2250 | 503 | 137 | .489 | | 2300 | 507 | 135 | .495 | | 2400 | 489 | 120 | .505 | We now propose fitting a pair of these carbs. on to the 6-cyl. unit for carburetter and induction pipe tests. We cannot do much more with the RR. horizontal carbs. on the 6-cyl. unit until modifications are made which are in hand. Hs.{Lord Ernest Hives - Chair} | ||
