pkitson Posted May 6, 2012 Share Posted May 6, 2012 I have seen the video of Mr. Stamans(?) Sherman testing out the new track. Does anyone know what engine setup is in that machine. Does not sound radial to me. Perry Quote Link to comment Share on other sites More sharing options...
Degsy Posted May 6, 2012 Share Posted May 6, 2012 It's fitted with a GM 6046 which is basically twin Detroit 6-71's and the injectors have been upgraded to modern ones for greater power and efficiency. Quote Link to comment Share on other sites More sharing options...
Adrian Barrell Posted May 6, 2012 Share Posted May 6, 2012 As Degsy says, a 6046 twinset with modern improvements. The tank belongs to Roy Aalderson, Joop supplies the tracks. Quote Link to comment Share on other sites More sharing options...
the_shadock Posted May 6, 2012 Share Posted May 6, 2012 (edited) hello, This particular Sherman, the one we are talking about in this thread, was built by Pacific Car and Foundry. Any chance to get its serial number ? P-O Edited May 6, 2012 by the_shadock Quote Link to comment Share on other sites More sharing options...
hummermark Posted May 6, 2012 Share Posted May 6, 2012 I spoke to his mechanic at a Tanks in Town and he said that he was running N80 injectors with two valve head which will be giving about 250hp per engine. I have since been told by someone else that it is a four valve head that is fitted which would give 270hp per engine with the N80 injectors, presuming that you advance time the engines and use the modern larger ported liners and the higher compression pistons. Not bad considering the original combined horsepower is 375 at the prop-shaft! If you type M10 Achilles Tank Destroyer in the search engine of this forum you will see pictures of 6046 twinset engine restored and unrestored. His Sherman certainly pulls well and sounds good when I followed it for a short journey in Tanks in Town. Mark Quote Link to comment Share on other sites More sharing options...
pkitson Posted May 7, 2012 Author Share Posted May 7, 2012 Thanks for the info gents. I had heard that a twin 6-71 had been fitted, but doubted it could be shoe horned into an engine compartment built for a radial, there is about a 2 foot difference in length, and then you need to sqeeze in the radiator. Any photo's of the engine compartment, it would be a work of art, and all that torque! Perry Quote Link to comment Share on other sites More sharing options...
Adrian Barrell Posted May 8, 2012 Share Posted May 8, 2012 I think the bulkhead is no longer as built..... Quote Link to comment Share on other sites More sharing options...
