Thanks, Vettedog, for posting that information.
I have been gradually collecting graphs, facts and opinions for an article for our (Triumph) club magazine, so your graph is appreciated.
As Sammy points out, that's not too bad for basically stock; do you know your actual compression ratio? And was the curve corrected for standard atmospheric temperature and pressure?
My TR4a made 91rwhp and 110 lbft of torque, average of 2 runs, about 4 years ago. I now have about 100rwhp and 115 lbft of torque, after spending much money on a cam, bigger valves, lightweight lifters, chromemoly pushrods, electric impeller fuel pump etc. but can't find the print-out so I will have to try again when I get the rebuild finished.
Most of the stock"ish" TR6 curves I have seen peak at around 90rwhp, so you're in the ballpark, but your torque curve might be slightly low, perhaps.
Thanks again, Simon.
