CAMSHAFTS

We have tried a variety of camshafts over the years for both 6 cylinder and 4 cylinder applications. Every company has their own theory as to what the best range of camshafts is.

We have found from experience that the TR2-4A Sprint camshafts listed will produce up to 125 BHP at the rear wheels and for similar purposes a standard TR5 camshaft will produce 140 BHP at the rear wheels. Our rally camhaft for TR2-4A engines will produce up to 140 BHP at the rear wheels via two 1 ¾’' SU carburettors.

All of the above of course is dependent on all aspects of the engine operating in accord from the air filter to the exhaust tail pipe. We are always testing new camshafts, therefore our opinion may change from time to time, please phone to discuss if you require more information.

For reference, the following 6 cylinder camshafts were fitted as standard:

If you wish to order a standard camshaft, please order the part numbers listed below. All other cars please refer to the original part numbers for your car if ordering a standard camshaft. Camshafts are available exchange as long as your old unit is re-grindable, otherwise a new camshaft will need to be supplied.
