Will youplease replace the 2800 constant DP X 3 dynamometer by an overhauled or new 2400 constant DP X 4 dynamometer in the above test house. With the former we cannot get below 900 R.P.M. full throttle and it is necessary for the tests which have to be carried out to be able to pull down to 500 R.P.M.
