So why don't trucking companies use a couple light weight Eco motors:
remove 1 big heavy expensive oil change diesel that makes 450hp & 1650lb-ft of torque that doesn't matter...
replace with 2 x 365HP Eco's that would make 730hp, but still deliver 420lbs-ft of torque down the drive line... but that doesn't matter - so this arrangement will "smoke" the big lazy 15 litre ISX ...
right?
Right the 730 hp gas setup with definitely smoke the 450 hp diesel.
Now longevity may be a different issue. But while the gas is healthy and producing 730 hp it will be a no contest.
Two 365 hp Ecos will have 840 ft lbs of torque. In first gear the Ecos can put about 6200 ft lbs of torque down the driveline with an Aisin 6 speed transmission.
How can 2 x 420 lbs ft torque engines develop 840 lbs ft of torque at their crankshafts?
Double the power yes but show me the math how they can increase torque beyond their capability at the crankshaft by being connected together.
