Are gas engines ever going to catch up?

If you think the EB engine runs rich in extended boost, where do the "extra", likely unburned, fuel byproducts go? I realise you believe that the fuel is used for steady cooling, but wouldn't that pollute too much? I conclude the EB does not run excessively rich because it is not allowed, and fuel requirements are normal for the power levels involved.
It goes through the cat and out the tailpipe.It goes through the cat and out the tailpipe. That's why we have dozens of post like this. And this is through a cat and the pipe still looks like diesel pipe!

I believe Ford has tuned the EB engine to not require excess fuel during boost and the Ford EB is just as efficient, likely more efficient, than the GM 5.3L V-8 while under power. The 3.5L EB makes 365HP/425ftlbs while the 5.3L makes a competitive 355HP/383ftlbs.
Believe what you want. All you need is a scan gauge and an Ecoboost to find out.


Then we may compare the Ford 3.5L EB to the GM 6.2L EcoTec3 V-8 for power. The EB makes 365HP/425ftlbs and the EcoTec (ET) makes 420HP/460ftlbs. Ford is discontinuing the 6.2L in 1/2 tons, so the 3.5L might get more, yet untapped, power.
I agree, this may be the case.

When at cruise, the turbo merely "idles along", spinning freely with intake and exhaust flows. The only impediment is the slight drag of the bearing which robs very little power.
Tell you what, you take an exhaust backpressure test per-turbo and then take a post-turbo test and see if you think the same way.

The final item I can't get by, is the physical fact that the turbo derives all it's power from free, formerly unused exhaust heat. The turbo uses this "free" energy to eliminate pumping losses while it emulates a larger displacement engine. The effective "free" reduction in pumping losses is why I believe a turbo'd engine can be more BSFC efficient than a N/A counterpart. I think Ford, and some European manufacturers, believe it too.
LOL, this is the biggest fallacy of all. Some really good reading that will explain why turbo's are not free energy.

For now we will have to agree to disagree I guess. I do appreciate the argument, as it helps weigh the truth.
