How Powerful are P2s?

Post by GOY189 » Thu Jul 28, 2016 11:34 am

Jeff Lee posted a facebook question about the BHP of P2 Rovers.

Jame's Taylors book has the following figures:-

10hp 44bhp (SAE) @ 4200 rpm '34-'38 48bhp (SAE) @ 4200 rpm '39-'40 and '46-'47 twin carb variant ('38-'40) not stated
12hp 48bhp (SAE) @ 4200 rpm '34-'38 53bhp (SAE) @ 4200 rpm '39-'40 and '46-'47 twin carb, High compression variant('36-'40) not stated
14hp 48bhp (SAE) @ 4600 rpm '34-'38
Speed 14 54bhp (SAE) @ 4800 rpm '36
14hp not stated '39-'47(single or triple carb variants)
16hp 60bhp (SAE) @ 4600 rpm '37-'39 66bhp (SAE) @ 4600 rpm '40 and '46-'47 triple carb, High compression variant('39-'40) not stated
20hp not stated ('37-'40) - However as I suspect Rolls-Royce would say, "adequate"!

Hi Mike,
Was the increase in HP for P2s after 1939 due to change of carb ?
1937-20 SS _ 1938-20 SS _ 1946-16 SS _ 1947-16 saloon
