All,
Since my data was the source of the Excel file, I went and tried to find my
original source for that data. Couldn't find it on my current computer so I am
abandoning that data. I'm sorry for any confusion.
I did digitize the graph sent by Harold M and have attached a new Excel file
showing the torque and HP for the Mk III derived from that graph.

Gentlemen,
I don't often disagree with information posted on this board but the recent
Excel chart of Hp and Torque is either a highly modified engine or wishful
thinking. The published data for the Mk III is maximum power of 149 bhp at
5,250 rpm and maximum torque 173 lb. ft. at 3,000 rpm. I have attached a copy
of a HP and Torque curve from a period publication I have. The attached chart
has BHP, Torque and Brake Mean Effective Pressure for both a Mk II and Mk III
Healey.
If there is a 250 HP Healey engine out there that generated the curves on the
spreadsheet please send pictures.
Harold

Thanks. Just what I was looking for. Anybody have data for lower than 3000
rpm? Does the attached make sense?

Is there an easy way to determine the various installed ratios? I'm curious as
to how my mph vs rpm stacks up. Also, is there a torque curve available (BJ8).

It's all positive Bob been running this since Lemperts first edition 3.54 about
10 years ago or so .
Lots of power to start off in 2nd gear and about 2700 rpm at highway speeds
70/75 mph .

Anyone running this setup? Pros? Cons?
