DanMtl Posted June 22, 2020 Share Posted June 22, 2020 Hi, I have a Mack DM600 (6 X 6) which I converted into a dump truck with a 20 foot box which is awsome in the woods, but it needs more power. I think I have a 239hp engine with a 7 speed Maxitorque transmission. Is there anyway I can boost that engine to get more hp out of it ? I dont know if its true but I read somewhere is could go up to 355hp. Thanks for your expertise :) Quote Link to comment https://www.bigmacktrucks.com/topic/62991-need-more-power/ Share on other sites More sharing options...
alex g Posted June 22, 2020 Share Posted June 22, 2020 You can plug of your Aneroid valve and turn the governor up on the back of the pump which may give you a bit more snap but your very limited to any large power gain without spending a pile of money on your injector pump. You probably have a 237 HP engine. Its a good set up and it's built with low HP to not self destruct in its previous life as a concrete truck I assume. Where are you located? It looks very Canadian Quote Link to comment https://www.bigmacktrucks.com/topic/62991-need-more-power/#findComment-453916 Share on other sites More sharing options...
Outbehindthebarn Posted June 23, 2020 Share Posted June 23, 2020 I see a tip turbine scoop... so.. its probably a 285 now and could be a 300 with minor adjustments.

I do believe that's just an intake for cold starts. Quote Link to comment https://www.bigmacktrucks.com/topic/62991-need-more-power/#findComment-453957 Share on other sites More sharing options...
