MG MGA - BP15 vs. 15 GD horsepower dif
|The horsepower for the BP15 engine is stated @ 68/5200 and the 15GD is 72/5500. Is this difference due just to the increase in RPM or were there any other changes when the BP block designation was changed that account for this?|
|It is a minor flow difference bewteen the very early heads and later heads.|
|Does that mean that you can increase the HP of a BP15 engine to 72hp if a later head is installed?|
|Thanks Bill. After reading what you posted, I went to the factories Special Tuning publication and on pages 16 & 17 it discribes and shows the changes to be made in the earlier heads to achive the increase. It also gives the numbers for when the changes were made.|
