definitely sounds fun but i would check out the pricing. if this package only includes what that article says it does you may be able to buy the parts and do it/have it done yourself cheaper.

 

Glad to see someone finally working on that engine!! 70hp from those mods is not bad at all!

 

Nice. What are the 1/4 mile times for the Taurus SHO? It is the closest thing to the stock EB MKS. Just tack 1/2 a second on the time and that should be close to what the stock EB MKS would probably do.

 

There's at least on in the 12's without major mods.

The price isn't totally unreasonable but then there is the Hennessey reputation for screwing people to contend with.

The good thing is that there are probably more folks likely to get involved in tweaking the EB, Hennessey is just the first big name to go public with the plan.

 

This is retarded, the reason ford didn't make it 400+hp themselves is because they do not have a tranny that can hold it reliably. I see catastrophic tranny failures in the future for people that mod this platform.

 

I thought the 6 speed select shift transmission was good for nearly 480 ft lbs of torque?

I must have gotten confused with something else. Nothing I found mentioned the maximum ammount of torque ahd RPM's that the transmission can handle. I am sure that Ford wouldnt just throw that # out there, although it would be nice to know.

Here is the Ford.com press release on the 6F-55 (what I have mistakenly called the Select Shift).

6F-55

 

435hp barely gets a C5 Z06 into the high 11's

 

So 13's out of the MKS is respectable then.

I really need a crash course in Drag Racing. 13 second 1/4 mile does not sound impressive but a 9 second 1/4 mile does. :dunno:

 

Transmissions seem to get way under-rated powerwise but they need to be to maintain a buffer of safety.

Automatics in general are really questionable these days but they can be made to handle increased power.

This is exactly why they should have had a manual trans as an option for the SHO as they can typically handle a lot more power reliably.

There's plenty of transmissions out there that'll take the power, it's simply a matter of Ford making the effort to source one that can handle it.

A great example of an under-rated trans is the FRPP T-56, they have it rated for 440 lb.ft. but in the world of '03-'04 Cobras 440 lb.ft. is on the low end of the average and there's guys well over 600 lb.ft. on stone stock T-56's.

The really go fast drag guys are actually running antiquated (not really) 2-speed Powerglides in their cars because they can handle FAR more power than even a profesisonally built 4R70W.

 

They should offer a manual, I absolutely agree 100% with that. Hennessey I'm sure re-calibrates the auto with upped line pressure and such, but it can't take a transmission that will surely fail under that kind of power and make it last.

 

It's not about upping line pressure, it's about changing the torque management throughout the power range... on launch... and on shifts.

It's a complete reprograming of the TCU that will make the tranny last.

 

If making the tranny hold over 100hp and 50ftlbs then what it was barely intended to was as simple as a flash. Why didn't the Ford calibration engineers that tune the ecoboost make it more powerful? They (ford) had the ecoboost making well over 500hp and it took it like a champ They had to detune the powertrain in order to make the drivetrain last. I know people in the calibration department at ford, this info is coming from the horses mouth. Ford has always had this problem.

 

It's not solely because of torque-handling that they are tuning those trannys the way they do.
They also tune them for driveability reasons... most people don't want to have to reign in all the available torque at launch, and shifts, because it takes away from the comfort of the drive.... particularly in a family cruiser or luxo-sport vehicle.

The added benefit of only using 50% of the available torque at shift is that it's not as hard on the tranny as it would otherwise be, so you can get away with a lesser transmission with more horsepower.

I'm not taking issue with you or your source, I'm merely adding information.

 

Its cool I'm just pissed at Ford that they haven't stuck a beefed up manual tranny behind it.

 

I didn't see any price on their website, but the package does include a warranty, amongst other things:

MaxBoost 435 Upgrade for the Lincoln MKS Includes:
• Hennessey Dual Cold Air Induction System
• Hennessey Polished Intercooler Piping Upgrade
• Engine Management Software Upgrade
• CORSA Stainless Steel Cat-Back Exhaust System
• Serial Numbered Dash & Engine Plaques
• Exterior MaxBoost 435 Badges
• Exterior Hennessey Badge (chrome or black)
• Hennessey Embroidered Headrests
• All Necessary Gaskets & Fluids
• Professional Installation
• Dyno Testing & Calibration
• 1 Year / 12,000 Mile Warranty

Even the autoblog article mentions a warranty for 1 year, so that isn't a terrible setup. I wonder how many miles this sort of modification would last, however. For someone who drives a significant amount, that mileage may come up quite quickly. And I'm curious to know the terms of the warranty, and if it would include allowances for drag racing, etc.

But Dan Kapp, Ford's director of the EcoBoost program, said he's been keeping the engine on a tight leash.
"We had to cap the boost on the cars," Kapp said in an interview at Ford's engineering center in Dearborn, Mich., last week.
Without limits, the engine's twin turbochargers would produce enough power to rip apart the all-wheel-drive transmissions used on the Taurus. Kapp added that Ford chose to offer the EcoBoost option only with all-wheel-drive because front-wheel-drive transmissions would have required a further limiting of the output.
That won't be a problem late next year when Ford launches the EcoBoost in the F-150 pickup, a vehicle with a heavy-duty truck transmission built to handle power.
"We can release a lot more torque in it, using the same parts we're already using," Kapp said. Torque is the turning power an engine exerts, and it's a key statistic for trucks. High-torque engines, such as diesels, are better able to tow heavy loads.

No numbers, but they are saying the transmission won't hold much more than what it puts out.

 

But the F-150's trannys WILL hold more torque.

Hmmmm sounds like a diesel fighter to me.
