2013 Tundra vs 2013 Ford

You are correct, they should not. However the shape of the plots tells me they are from a chassis dyno and the peak values should be down by 20 to 25% from advertised numbers from driveline losses. Do you see where I'm going with this..

No, not really. The shape of the graph should be similar regardless, once you take out the 20-25% driveline loss.

I totally understand the difference between a chassis dyno and an engine brake dyno, that's why I'm saying the plots from your graph are comparing data using two different techniques which is not relevant.

Yeah i can hear the yelling from here if GM or Dodge used a brake dyno for theirs and then stuck Ford on a chassis dyno and then printed up a dyno sheet as if they were all tested in an identical manner AND on the same dyno

Yep, just like if Ford had done the same thing. Point is, it doesn't look like that is the case. And, according to the poster who posted the graph, it came from PUTC, not from Ford, or GM, or Ram.

well then it would appear the only way to be sure would be to find the actual procedure and list how all the engines or vehicles were tested - hopefully either ALL engine or ALL chassis and on the same dyno

That's it? No driveability report? Come on! Did you tow with it? Does your dad tow with it? What does your dad say? :drool: I wonder what the price delta is today? My buddy bought the V8 5.0L a couple years ago because of te cost delta & newness reliability concern. He has been very happy with his V8. He is like me, occasional moderate tower.

My dad very rarely tows with it. I ordered it the way I would want one. It rides great but in my opinion all Super Crew F150's always have. It handles loads great. We put a 3000# pallet of salt in it with no issues. As for towing I did a comparison on here about 2 years ago using identical 20' enclosed tandem axle trailers loaded to 6000# over a 300 mile trip using my 08 Tiitan and his EB. I got 9 mpg hand calculated and he got 13. There is a big right up on this site about it.

If you don't trust the dyno charts, look at real world towing and 0-60 acceleration times that have been published. You will find the ecoboost out performing most any engine under 6.2 liters.

Can you post some of these comparisons you are talking about?

I hear ya - GDI solves a lot of sparky issues. What I find difficult to believe is building a gasoline engine as heavy as a diesel engine for diesel cylinder pressures, and still being "thousands" of dollars less costly than a diesel engine.

If you want to see something cool (as a motorhead), look at the Mazda Skyactive technology. 14:1 compression ration gas engines.

The 14:1 compression ratio on those Mazda's amazes me. I thought i read somewhere that Mazda had a diesel that was 11:1 and very efficient.

The engine doesn't work in the cold though. I was holding out to see if they would put it in the CX-5 but after reading complaints by people in other countries saying they were forced to use a different vehicle because the Mazda would start. I assumed that's why Mazda keeps saying they are going to release it yet hasn't.

The mileage thing Toyota vs domestic is a myth. Don't believe me check for yourself, the shuttle vans down at Disney world in Fl run 24/7. They never turn them off except to fuel them up. I sat behind the driver looked at the odometer and the Ford Van had 750K miles on it. I asked him - what's the secret getting that many miles out of a Ford? He said we do regular maintenance, period. Then he said they all brands, Ford, Chevy, Dodge and they all have the same mileage. I also have my mobile mechanic that does the service on my big trucks, his Toyota tundra has 850K miles on it. Many guys on the Dodge/Mercedes Sprinter site are getting 750K miles on their vans.

Lesson is, it doesn't matter domestic or Japanese/domestic if you service your vehicles you will get the miles out of them.

We all know of the guy driving the Volvo with 3 Million miles.
Man drives record 3 million miles in the same 1966 Volvo - TODAY.com

Vehicles for the last couple of decades are manufactured and built with computers, robots etc. so the tolerances are much tighter than when Henry Ford built the model T, which is still running by the way.
