Why wouldn't it make sense? Ford has pretty much said that that's the direction they're going. Power of of V8 when needed, economy of a V6 when needed.

Do a little research on the GM L67. I chose this engine because it's a high production OEM Supercharged V6. Even with minor mods they can produce 300/300 reliably, and have great torque curves. And with the advances in effeciency, the new blowers are boosting higher, with lower intake temps.

And what about the Buick GN's. They were putting down over 400/400 easily, and reliably. With a Turbo 3.8L, 20 years ago.

I'm sure with a little R&D Ford can come up with a very dependable forced induction, high production V6, that'll easily out do most v8's

Check this rolling start dyno graph. It's of a modded L67. The guy could'nt get the wheels to hook on the rollers from a standing start!

 

I hope ford will just lie and say the motor has 900HP and then we can focus on what really matters. MPG!

 

The fact is, the V6 is the best engine for power to size ratio.

 

Just imagine the power that even the 4.6L v8 would produce if Ford were to apply their new EcoBoost technology (direct injection, turbocharging) to it. Another thought: an EcoBoost 5.4L v8 would probably put out numbers that would be on par with the current 6.8L v10. I like that idea.

If Ford would embrace the idea of applying their new EcoBoost technology to their v8's, every one would be happy. In my opinion, the 5.4L v8 has good HP & Tourqe right now. Direct injection and turbo charging would only reinforce the motor's current strong point's.

If nothing else, EcoBoost would improve the fuel economy of any v8 that they might apply it to. My truck will get between 15.5 to just under 18mpg unloaded on the highway. I am more that happy with those numbers for a 5.4L powered F-150. When I want better mpg's, I drive my Saturn VUE that gets 25 to 29mpg. But you know what? I would buy a new F-150 with an EcoBoost 5.4L v8 in a heartbeat. Besides the extra power, I bet you could easily get into the low 20's in mpg. Improved power with the bonus of improved mpg's, sounds like a win-win situation, if Ford is willing to go that route.

The new Jag XF is getting a 300/310 4.2L
The XF-R gets a SC/IC 4.2L and 420/408

I'd imagine the 4.6, with forced induction, would prolly be capable of close to 500 HP?

 

The Jag motors are Jag designed and built. These share NOTHING with the Ford Mod motors. Jag also does their own R&D for their mills and use their own electronics. Only the 2.5/3.0ltr V6s that were/are used in the baby Jag was developed by Ford but these had Jag desigend intakes/exhaust, Jag spec'd cams, Jag tuned electronics, and Jag ported heads. The Land Rover now uses versions of the Jag AJ V8, not Ford V8s. However, the last generation Discovery Series II did use a version of the Explorer SOHC 4.0 V6 as the base engine. The top line engine in the last generation Rovers were 4.0 and 4.6 ltr V8s based off the old Buick 215 alloy V8 from 1960-63.....oh and the last generation Range Rover did use a BMW sourced 4.6 V8 for a couple of years until the Jag motors had been retuned for more torque at lower revs.

 

Well Ford did use the AJ35 For the Lincoln LS in 02.

The 3.9L (3934 cc) AJ35 variant is used only by Ford and Lincoln and is built in Ford's Lima, OH engine plant.

So, I'd guess they have a lot of knowlage about the Jag. And prolly used a lot of Jag engineering in the development of their own Modular motors? Just as they are doing right now with the 4.4 Diesel/Rover

 

Those numbers are impressive, however the torque isn't where it is needed for towing and power below 3600rpm is weak.

My 6.8l makes it 425ft lbs at 3,250rpm and makes 80% of its max torque off idle.

 

agreed, however, it is likely that car on the dyno had a 3500ish stall and an auto, which makes almost no point in dynoing it before that. Even then, I do agree that a turbo small motor making that much power isn't going to do it right off idle...

the 4.6 in the 03/04 cobra did (albeit underrated) 390/390, with a very flat torque curve.



I'd rock one of those in a truck in a heartbeat. I am somewhat suspicious of turbos pulling off the same torque curve though...

 

That run, the guy wasin 4th gear (direct) He had to start the run at 3500 RPM's. Just to get the Fiero to stay connected to the rollers.

If you could get a true run out of it, you'd see his Tq numbers are right at 400-450 pretty much all the way across the rpm band

There are numerous GM L67's (SC'd 3.8) that are running 300/300. Out off a little less than half the CID of your 6.8

I'm just saying that Peeps shouldn't get all worked up about a Forced Induction V6. They're fully capable of putting down great numbers.

I, for one, would welcome a properly designed Force Fed V6 in a truck.

 

Yes, Ford used the AJ in the LS AND in the T-bird but both those cars are Jag S-Types under the skin. Ford was working on the Mod motor design in the mid-1980's as it arrived in the 1991 Crown Vic. They bought Jag in 1989, doubt there was much technology transfer. Last I looked, Jag developed that diesel for the Euro market and to compete with BMW and M-B and their high powered, hgih speed diesel luxo sedans. With the org structure at Ford, it was a natural for the motor to be shared with Land Rover. I would like to see that motor in a F-150 with maybe a little less HP but more torque.

 

But did'nt the OHC 3 valvers just start production in 04? I'd imagine that a lot of Jags knowlage went into those designs?

 

This isn't directed at you fonefiddy, but you guys don't have a clue. Jag designed the AJV8s? Yes, Jaguar designed the AJV8s UNDER FORD'S DIRECTION AND APPROVAL WITH FORD'S MONEY!

The AJV8 is a FoMoCo engine, bottom line. Do you think Aston Martin "designed" the 6.0L V12? Nope, Ford engineers did that one, just like AJV8s were running around Dearborn and Arizona long before they were ever installed in a production Jag.

There is one simple reason why Jag AJV8s were never installed in Ford products, cost of manufacture. Mod Motors are cheaper and have more displacement capacity. And when push comes to shove, the Mod Motor will make comparable power to the AJV8s for the given displacement. NVH and physical size/weight is where the Mod Motors fall a bit short of the AJV8s.

Do you think Jag developed the AJV8's VCT and DAMB tech? LOL, the AJV8 was designed with Ford technology under the direction of Ford. If you don't think Ford doesn't know every single detail of the AJV8 and wasn't involved with every single step of R&D on that engine family, you don't know the facts.

 

LMAO!!!! I never understand why people choose to comment on a topic they obviously know NOTHING about.

Jag electronics! BWAHAHAHAHA!!!!
