Joey Mack Posted 11 hours ago Share Posted 11 hours ago How big would the transmission be, and the axles? I bet you would lose 3000 lb's of freight weight to be legal here in the U.S. just tossin my silly thoughts out there...

Probably need a weight permit just for the truck 😆 🤣 😂 😹 😆 🤣 Quote Link to comment https://www.bigmacktrucks.com/topic/76250-e7-350hp-to-500hp-that-will-live/page/3/#findComment-587692 Share on other sites More sharing options...
Mark T Posted 11 hours ago Share Posted 11 hours ago Probably not much different than something with a KT in it years ago as far as weight goes. Do wonder what transmission would put up with it pulling a road train down under. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76250-e7-350hp-to-500hp-that-will-live/page/3/#findComment-587693 Share on other sites More sharing options...
880joe Posted 10 hours ago Share Posted 10 hours ago I think they are just running the Ishift or Mdrive which ever you prefer to call it Quote Link to comment https://www.bigmacktrucks.com/topic/76250-e7-350hp-to-500hp-that-will-live/page/3/#findComment-587696 Share on other sites More sharing options...
Joey Mack Posted 9 hours ago Share Posted 9 hours ago Thats amazing. When I pulled MDrives out, i could pick them up and put them on a pallet for core returns.. how could a trans that light be strong enough to handle huge torque and truck trains as described? Must be a great engineering accomplishment... I havent a clue, just sayin..

Mark T Posted 9 hours ago Share Posted 9 hours ago Yep, I Shift. I guess that's why they're not 800 horse. Paul was right (again) I was reading about them for almost an hour. Then there's the part about them running on vegetable oil.

Also, the heads Pyromet valves and seats. Thats the recipe a friend of mine used and it runs really well, but its only got about a year of running on it so time will tell how well it holds up. I have not personally tried this, but im in the process of building a E7 Vmac with these specs. I have put aside 15k for this build. Was thinking about even doing ceramic coated pistons. I want it to live at least 500k with good power. I'll stud the heads if I think it's needed. Inconle valves ect. Im pretty serious Quote Link to comment https://www.bigmacktrucks.com/topic/76250-e7-350hp-to-500hp-that-will-live/page/3/#findComment-587705 Share on other sites More sharing options...

Im very interested in any projects like this. Ive read a couple post about guys using turbo off series 60. Im not trying to build 700hp +++ if I was convinced it would live i would tho lol.

Im really interested in usable hp. Not a grenade I think 500hp 1800tq is within reason for a E7.
