RE: Mountune extracts 684hp from 2.3 EcoBoost

[bigbadbikercats]

I’d like to see this in a Mustang - not because I think it would be “better” than a V8 running at a similar power output but just to mess with people’s heads... :-)

I may be missing a parrot here, but they already put the 2.3 turbo in the Mustang, which in itself harks back to the old turbo Lima/Pinto engined mustang.

Hmm. They used to get 1,500bhp out of a 1.5l turbo engine back in the 80s in formula 1, but that doesn't mean it would last long enough to use as an everyday engine (or indeed another qualifying session back in those days). I wonder how long this one will last with short runs, cold starts, over-revving before its warmed up etc? Give me a nice big unstressed V8 any day!

This is how I see it.

Give it a 3-year/60000 mile warranty or it just does not impress me one bit.

My very old Maestro Turbo had in excess of 250bhp and very nearly made it to the local shops, once, without breaking down

Not a 684bhp 2.3

In which case, I'll be needing my bus pass soon too.
Impressive but not floating my boat at all really. Would much rather a lightly tuned high capacity V8, (yes with the associated high CO2 and rubbish mileage).
I suspect an engine like this to have virtually zero character and to be highly strung.

Zero character? Have you ever experienced a highly tuned turbo engine? They can have just as much character as anything else, it's just a different kind of character.

Things have moved on quite a bit since 1986.

Just like the power figures.

Yes, I have. Apart from a Scooby, what four cyls lack most is character. We can agree to disagree I suppose though?

So primarily just half of the engine components, AND a built block, running on completely different fuel and fuel system, exhaust system, intake system and engine management system.

Just like that ey?

We all know how American horsepower never measures up to real horsepower.

[Gavin Smith]

Bang! That’s the sound of the dead engine.

[RPJEssex]

I’ve got the 375 upgrade on my RS and that feels rapid, so god only knows how nearly twice the power would feel! Mental stuff!! I wonder how the GKN Twinster system deals with all the additional power? Not that I’m doing anymore to my vehicle, but I’d love to have a go in this car, sounds like it would be an absolute weapon.

“Primarily” only a new head and bigger turbo.....

I wonder what the secondary mods are - pistons, rods, injectors, inlet, exhaust, quite a lot of mapping, etc

That said, with modern materials and manufacturing processes, the specific output is probably capable of being very reliable. I have put well over 200,000 miles on a 20 year old 2-litre turbo with an output of 240bhp per litre and I didn’t have the resources that Mountune have

[9k rpm]

Boooooooost

Imagine the lag. I bet the turbo is the size of Belgium.

[GreatScott2016]

It might be a cracking chassis, but that power is toooo much, even for a 4WD car. Mine struggles to handle 350hp so while a stunning engineering achievement, not sure how practical it would be in the real world.

[Evolved]

Is it really that much harder to extract power from a DI engine? Never knew that.

There are tons, and I mean tons of stroker 2.3 Evo’s running that kind of power fairly easily tbh.

There is a graph in the vid. The rpm scale somewhat unclear, but torque curve has a sizeable flat portion and the fairly steady rise of torque up to that plateau suggest that lag isn't at all that bad. Also peak power is reached quite high up, meaning it isn't entirely relying on massive boost for power.

Far removed from the high hp tuner specials where the torque curve has the shape of a Matterhorn peak in death Valley, and any significant power is delivered in a rpm band barely 1000rpm wide...

So who is making a reliable 1500hp 1.5l engine these days? 1hp per cc is as impressive today as it was then.

Confusing lag with boost threshold.

[Escort Si-130]

I cant see these selling by the bucketload as PH makes it out to be. Most of these 400+ packages on cars, seem to be sold to serious track day people and a few willy waving road champions.
High bhp also equals piss poor mpg.

Yep. Ford Coyote and Dodge Hellcat both underrated from the factory, both produce significantly more power than claimed.

TBH I'd much rather see Ford produce a 2-litre naturally-aspirated I6 with about 240bhp for the Mustang, maybe as a 48v mild hybrid if that helps it pass emissions. If Mazda can do it...
