Great torque numbers still wishing you guys made something for us non ST owners.

Why you making excuses for the decisions you made?

The standard Durtec does not hold a candle to the Ecoboost motors. You would be spending a ton of money just to match it potential. Its cheaper to just trade-in your standard Focus and carry over the negative on the ST.

Your payments would be higher but hey, you knew the ST was coming, you could have bought a cheap car just to hold you over. Save money and put more down on the ST with a lower principle and payment.

Boo-hoo sucks to be you wishing Cobb make stuff for standard Focus when they've only dealt with boosted cars their entire existence, good luck with that.

Face it you bought a slow car, so live with it.

How do you figure that?

I too am Happy to see COBB in here. I used some of there stuff on my MS6. Great products. And yeah ECOBOOST motors...flat out kick ass. I struggle to even use Ecoboost anymore...its just Fords boosted engine, there is nothing ECO about it when I drive my ST or my F150

With all do respect to frinesi2.....The logic you are using is understandable, trying to think outside the box, but you would have a small fortune getting the Duratec motor up to the point of the ecoboost is already. I would start with the best and add my time and money from there if you were really serious in building a monster. This comes from one of the many guys that has dumped a ton of money into my cars in the past.

These N/A motors are more advanced than you are giving them credit for, even with just an intake and exhaust they are picking up nearly 20 hp with the stock calibration. There are still more gains just from an exhaust manifold in some applications.

It is running at 12:1 compression vs 9.3:1 of the ST, which is why even with up to 20 PSIG of boost pressure only makes 93 more horsepower at the crank shaft as the naturally aspirated engine as a stock baseline.

The higher compression is more efficient at extracting power out of the fuel when you're out of boost on the turbocharged application.

Without tuning however there is only so much can be gained on the stock calibration.

The N/A powered Focus also weighs 275 lbs less than the EcoBoost powered ST, 3223 lbs is the estimated curb weight of the ST, vs 2948 lb for the N/A hatch.

It should be feasible to get the n/a engine up to around 200 hp or slightly over for the 5MT, but until proven otherwise the DCT models are constrained to 180 lb-ft of torque per the rating on the gearbox by Ford and Getrag (250-280 NM).

Personally I am looking for 2 specific types of tunes.
1. Eco Tune for daily driving.
2. Full on tune for track days on road courses.

Both of these keep in mind to be used on a completely bone stock Focus ST. I do not plan on doing any "real" mods to the car. There will be some but they will all be OEM upgrades from Europe.
