thanks jbird/kosai.

kosai, i’ve only heard of differently sized sequential turbos. can you clarify the difference between a parallel and sequential setup for me (if not by size)? i appreciate your input.

on the subject of twin turbos, was it the stealth r/t tt and 3000 gt/vr4 that had sequential turbos? whichever car it was, i remember reading that lag was almost non-existent and boost was consistent. mmmmmmm boost.

Let’s skip the twin-turbo Focus and bring back the taurus SHO

If they go with a parallel system, they could get out of a lot of the complexity of a sequential system (though that would depend on the type of sequential setup). A well set up sequential system ‘may’ be able to give better characteristics though. It’s also kind of a misconception that sequential turbo setups involve two differently sized turbos. It’s actually pretty common to feature two of the same size.

GMCsyclone they’re probly two equally sized small turbos that spool up quick, yet combined push enough air to give a decent powerband

I’d rather enjoy driving a good twin turbo V6 over a V8, unless it’s a Corvette LS7 or Ferrari V8.

Let’s see Ford put a twin turbo V6/V8 in the Mustang, too.

autonutt answered my question just as I was preparing to type it. i couldnt figure out how ford planned to improve fuel economy by adding turbos. more air requires more fuel. but autonutt hit it on the nose: use smaller-but turbocharged engines to produce competitive levels of power.

thanks autonutt.

does anyone know if the turbos are different sizes to prevent lag, or equally sized for maximum power?

Good, good. It appears someone at Ford has finally woken up and decided to call some sane shots.

The only way to improve fuel economy with turbochargers is to decrease the engine displacement – slapping twin turbos on an existing Tiburon or Milan motor will only yield more power, not improve gas mileage. Ford’s plan is to offer smaller-displacement engines with twin turbos in place of larger existing motors, matching the current engine’s power but substantially improving the economy. I understand and encourage this strategy on cars like the Focus, Fusion and Taurus, but saddling a supposed “prestige” model like the MKS with only a turbo V6 when all of its competition offers more prestigious V8s seems like a bad strategic move.

Adrio – I dunno. They really took the time to make sure the Edge got off without a hitch, and the Fusion has been rock solid. Maybe they’re making a real effort at reliability now.

LP640 – Dang.Tough crowd.

Ford’s been doing little things here and there. They quietly have been assembling a sound portfolio…I think that all they really need to do is learn how to market their product. I hope they get it right with the upcoming Taurus.

The turbo in my Volvo helps a lot with gas mileage! 21/30 MPG. I average under 21.5 mpg (lot of city driving).
It should really help with Ford/Mercury/Lincoln/(maybe)Mazda cars and crossovers!

All the reason to get closer to the LAME 32 MPG required for the year 2020 or whenever….

I’m interested in the use of forced induction to increase gas mileage. Maybe they can teach me how to twin-turbo my Tiburon so I can get 28mpg!

I”m a ford fan but I have to admit…..The first generation will probably have SO MANY PROBLEMS. I wish I could have confidence in ford to bust out new tech, but I don’t. They’re probably gonna rush it and end up with a bad reliability rating.

lame ford need more than improved fuel economy to save them

wonder if they’ll make cheap kits to retrofit to past ford models to “increase fuel economy”, wouldnt mind having a couple turbos on my 4 valve

well ok if it’s similar to diesel’s mpg then it’s all good even from Ford.

Isn’t the Mosler M600 using a twin turbo Ford 3.5L V6 to get 415 HP? I could imagine a nice, boring, Mercury Milan sedan with one of these and AWD…
