Glider Kit CAT OR Detroit

First off, lately I have been getting high7's low 8's in MPG. So a smaller engine is getting better mpg. (im rarely under 75K) And yes I can make it all over PA and any ware without downshifting as long as no one else slows me down. If an engine is large do to tunes, that's one thing, but an larger engine that is just a large engine will be less efficient.

That being said, some of the epa crap is stupid, but a lot of ot really does help our environment stay cleaner. Some of these tuned trucks billow black smoke every time they hit the throttle. That's not cool no matter how efficient it is. Those trucks should be taken off the road. There are emission standards for a reason and if you want you r kids to be able to breath when they grow up, you may want to not drive a supper pouting truck.

 

Now it's turned into a tree hugging argument. OK maybe OP should forgo a glider altogether and get a 2014 truck with dpf/scr and our grandchildren can thank him later. A properly set up and tuned high horsepower engine does not smoke.

 

I love the environment, that's why I try to use up as much of it as I can.

 

If that were true, why don't we all get 2000 horse engines. If your not tuning an engine and leaving it stock...500 hp seems to be the happy medium. Now if you tune a 500 hp to 750, yes you could get better mpg, but its important to still consider environmental concerns. Now clearly if you have a motor that is 600hp stock vs a motor with 500 hp stock, and your less then 80,000 pounds, unless your on nothing but hills a 500hp will get better mpg. If your not using most of the motors hp, your turning all that extra heavy weight for nothing. Simple physics says it will need more energy. Now if you spend all day on hills using your engine, yes more hp will help, but most long haul drivers dont spend all day int he hills. Now the OP says he was lookign for short haul. Depending on his area, you MAY be correct IF he plans on hauling in lot of hills.

 

Please...if you don't know what you are talking about, just close your mouth and listen.

Is that a H.P. Upgrade? Maybe that's the secret to those ###### detroits.

 

You highlighted the part about weight...there is no dought Cats are heavier and a bigger block is more weight. You have yet to provide graphs, data or any real evidence to any of your claimes on this thread. Real world experience on one truck that is getting worse mpg then mine does not prove your point.

 

Maybe you should be a tad more clear, as your own post implies a 600hp engine weighs more than a 500 hp engine. You didn't specify anything other than horsepower.

And since it seems you don't follow along very well, I'll go pull all the things the show you how wrong you are. Not that I expect you to ever to acknowledge you're mistaken, as you haven't done it once that I can remember in any single thread you've posted in. I've taken the time a couple times to try and teach you something, in a couple threads, yet you insist on being an argumentative ### who refuses to see where you are wrong. Now this will take a while, and why I'm wasting my time I don't know, but here goes! I'll be back later.

BTW, we haven't disagreed that as a general rule Detroits get better mileage, this is about performance, which you insist the Detroit is a better performer.

Now if I can just remember who I gave the gauntlet of lost causes to, I'll be all set.

 

Funny Thing my cousins 625 C15 (that's stock) gets better fuel mileage then my 550 C15 (that's stock) pulling the same loads, we have same diff rations, tranny, and trucks aside from motor.... I JUST BLEW YOUR THEORY OUT OF THE WATER!!!!!
