I have been watching the 2015 developments with keen interest, especially the 2.3L ecoboost motor. 300hp (270ish) at the wheels is nothing to sneeze at.

But my concern is aftermarket support. Exterior parts, grilles, spoilers etc. will fit all versions. What I am referring to and hoping for is the level of aftermarket engine mod support like one would find on imports.

Currently there isn't much love for the V6 mustangs as far as engine mods, so will the 2015 ecoboost suffer from the same lack of love from the major industry players that make engine mods?

 

Still too soon to speculate anything. What more do you actually want as far as mods go? A CIA and tune will wake that car right up.

 

you can get tons of stuff for the v6. I am sure the focus ST part will spill over in the mustang market.

 

I think we'll see more of a push for go fast goodies for the 2.3l. There are tons of companies who have been stuck making accessories for 4 cyl. turbo cars. Now they have a true enthusiast's canvas to start from.

 

The HP rating from the manufacturer are not RWHP. The 4cyn Ecoboost will be lucky to see 260 at the rear wheels.

 

The OP knows that. That is why he put "270" in parentheses.

 

Opps. Beat me to it. ^^^^^^ That's what I get for watching football while trying to post.


I know that. That is why I put the speculated HP numbers in parenthesis. Depending on transmission the drivetrain lose can be 18 - 22%. RWHP on the 2.3L may actually be closer to 234 with a MT6sp, but again I am only speculating.


From what I have read on other forums regarding the new header, it will be pretty difficult to make that any better from a aftermarket manufacturer as it is part of the twin scroll turbo. So the way I see it we will see may see axle backs, CAI, tunes etc. Maybe larger turbos? But probably no cams, pistons, cranks rods, that we see on the import scene.

 

Right now in Ecoboost DI engines the biggest hurdle is the fuel injection. I have yet to see an aftermarket for the Taurus SHO after 4 years on the market. The DI operates at a much much higher PSI.

Maybe with the mass production of the Mustang Ecoboost someone will step up to the plate. But right now HP is limited by fuel delivery as far as I know.

 

Agree that the DI has proven to be tougher to tune than port injection turbo cars of the past. I know a guy with a turbo Cobalt SS which has a DI engine - the workaround for increased fuel flow required for his big turbo was actually an additional fuel injector (port injection) that acted in parallel with the stock DI system. Perhaps something similar will be worked up for the Mustang... or maybe I just gave away my brilliant idea to make millions

I would imagine a lot of tuning options with the 2.3t though as turbo cars in general respond very well to tuning and other modifications.

 

There is a German Turner (Wolf Racing) that states they are able to take the 2.0 Ecoboost up to 370hp and 409tq. Not sure what, if anything, was done internally.

 

Don't Lund, Hennesey and Lethal Performance all offer tunes for the 3.5TTs?

 

Which is the same as the v6 you drive right now. but tune for tune the turbo car will see more of a increase.

this from the steeda site for the ST motor

if the 2.0 is seeing those kinds of increase I can not wait to see what the 2.3 will offer.

They have SHO kits. The ST focus market has a huge amount of stuff. The have turbo upgrade, piping, tunes, charge pipes, mounts, exhaust, spacers, blow offs and much more. I am betting that most of the stuff will bolt up.

between cobb, steeda, ford racing, cfm, fswerks, roush, Shelby, mountune and many others its going to be a hot market.

 

Yes they all have tune kits and bolt on kits but that will only go so far. They haven't cracked how to increase the fuel supply yet with the DI and the fuel system.

Imagine if you had all the kits for the 5.0, 4.6, 5.4, and 5.8 but you couldn't increases the injector size or fuel pump. You'd hit a ceiling petty fast on what you could get out of the motor performance wise.

 

I'd like to see Cobb jump in. I ran their tune on my Speed6 and love the AccessPort as a tuning device. It blows the SCT handheld out of the water.

 

If the ecoboost is anything like the F150 ecoboost,..you have nothing to worry about for performance parts. There are a bunch.

 

wouldn't be cool if they made a whipple for the f150 ecoboost?

 

That would be a very expensive build. Ecoboost engines are twin turbos.

 

I know! sounds fun

 

Intercooler upgrades, boost control will happen quick. It's just not certain what these engines can safely hold yet. If the ecoboost mustang can safely hold 400-450 at the wheels, then it'll be a true contender with gears, TQ converter and suspension.

 

Many people are saying Ford under-rated the Focus. So it's possible that will happen with the Mustang eco-boost as well.
