Don't know how they are going to pickup 45 torque on the current 5.4L while only adding 15HP. Only way they will mathmatically make sense is if they lower the redline. 45 tq extra in the current powercurve will have the engine over 600 at the flywheel.

 

If that's true I wanna put my deposit for a 2012 Shelby NOW

 

What if the "Roadrunner" is like the Coyote -- 5.0L engine with absolutely no FI..............?

 

If Ford was smart they'd keep the current 5.4L in the GT500 which is a proven HP beast and then move to a built twin turbo 5.0L just in time for the Z28.

 

Mike, our sources are pretty good too.

 

I dont know what to believe because you and Brad are both good sources and honest. I just think your sources are the problem and maybe even Ford does not know what they are going to do. The 6.2 is a prime example with on again off again on again mess we all lived through.

HOw can the road runner be a non ecoboost and twin turbo? Isnt that an oxymoron? You lost me on that one.

Anywho, last I read there were some TT 5.0 prowling around but it was killed for some mechanical reason I cant remember. But on the other hand if they are going to replace the 5.4 and 4.6 with the 5.0 it makes no sense to me to built a 5.4 specifically for a low volume car. Maybe they will work on a SC 5.0 instead of TT?

 

Speculation:

What if the 5.4L Road Runner is not a modular 5.4 but a Coyote 5.0 bored and stroked to 5.4?

 

iS THE COYOTE NOT A MOD MOTOR?

 

Yes, I know TMS has excellent sources too. I'm not doubting that. Like I said, stay tuned. I like the point about the 6.2-L.

EcoBoost requires 3 things: major downsizing, boost and direct injection. No DI for Coyote. We could argue if .4 liters less than the 5.4 is 'major' downsizing.

:-)

 

Somebody brought up a good point at BON that since the crown vic and E series vans would live through 2011 that maybe they could make a case for the 5.4. Both get 2v versions of the 4.6/5.4 respectively. Not doubting you Mike or Brad. We will just have to wait and see I guess.

By the way, when is the embargo up on the F150 Ecoboost?

 

Another reason I'm waiting for the 2011... I hope the order banks are opening in late November as reported.

 

My interpretation of the Ecoboost line is that they're existing FMC engines fitted with a modular package of turbo(s) and DI setup. The 'Road Runner' may be a purpose-built high hp FI motor that is beefed up, not just the Coyote motor with a TT setup slapped on it.

 

EcoBoost thus far has been applied only to low-boost set-ups meant to emphasize efficiency over total possible power. IF they brought out a turbo mill with high boost (and less efficiency emphasis), they'd probably invent a new label (or revive TwinForce?) to separate it from the EcoBoost line.

No, Coyote is brand-spanking new.

 

Again, I'm willing to bet that the "Roadrunner" will be a low-volume engine, devoid of DI and FI.

 

good thinking! I'm sure the coyote won't have the bore limitations of the mod motor.

No, the coyote shares nothing with the mod motor. All new! we can finally retire our near 20 year old architechture.

 

Road runner is not a 5.0TT, it is the N/A Engine that will going into the Boss.

 

6.2?

 

Question is will 555hp be enough to kep up with the Z28 which should be on the lots by Sept. 2010?

 

I agree with you there. It won't see duty like the Coyote, but it'll get put in its share of things.

 

1. The Z/28 won't be on the lots IN 2010.

2. The aluminum block GT500 weighs the same as an SS. Once you add the blower and all associated parts, the Z/28 will be over 4,000 lbs.
