Does anyone know roughly how much torque the Austin Seven engine produces in any different configurations?
Of personal interest would be something similar to my car. It's a 1934 RP. The bottom end is new with a Barlow crank and rods, and 57mm pistons from Mr Betts. It has a Ruby high compression head and an SU carb. Exhaust is standard.
Obviously no-one will be able to say without having it on a dyno but just looking for an order of magnitude, or indeed if anyone knows what the standard car made, or what your highly tuned race engine produces.
interesting that you are asking about torque — most people seeking improved performance seem to want extra bhp. I would have thought that is easier to quantify than torque, but then I’m not an engineer. My special developed around 30 bhp at 500 revs. I would allow at least 10% over estimate but 27 bhp will provide lively performance if the weight is kept down — perhaps less of an option in your case.
Thanks
