Anyone heard of a Boss 351 or 429 for the new gen?

The V8 won't go away. If anything, I foresee smaller V8s with forced induction replacing our current ones. Say 3,6-4.0 TT, such as MB, Audi and BMW are using today.

Close, 3.8TT. But yeah, the way things are going with the V6s in the F-150, I expect the V8s to go the same way. Turbos turbos for EVERYone!!!!

For now od rather stay n/a because it less upkeep than turbo and even supercharger systems but as more manufacturers start using them and they become more refined theyll be more manageable.

I kinda agree. I've always been an N/A fan. I'd be okay with the more exotic build materials coming into play (carbon fiber etc) and then just downsizing the N/A engines - say 4.0 350hp DI V8 but 3000lb curb weight. That would work for me, and be pretty close to the power to weight ratio of the Terminators.

Engine blueprints are much like this. For instance, the Trinity had a target of 650HP when SVT finally settled on performance requirements. The resulting SAE-rated 662HP is the result of "building in" some room for improvement, if you will, without pushing the block, heads, crank, etc., too close to the holy-****-this-will-blow-up-before-the-ink-on-the-warranty-is-dry point. It may be capable of producing an output of 7 liters, but that doesn't mean it's supposed to.
the 7 litre capability was in the bore/stroke capability to reach up to that displacement...wether for a stump pulling truck motor, or a next Boss429 for bragging rights, who knows...


My opinion, I don't think any car maker--with very, very few exceptions--will ever produce in mass quantities an engine that displaces more than 5 liters by 2020. I would be absolutely shocked if Ford produced anything bigger than the Coyote--that's designed for something other than their trucks--ever again. The trend is small, green, economical power. The automakers aren't being given much of a choice.
agreed- but one can always dream

It's why so very badly want to get my hands on a '69 or '70 Mach 1. Aside from being arguably the most beautiful car mankind ever has or ever will produce, the engine was big. It will be a gorgeous dinosaur right next to my 2013 GT500 dinosaur in my garage. Hopefully. Maybe. One day.
mines kinda not a car currently, but hoping to have it rolling by next fall- rrs notched towers, some kind of coilover struts, undecided on steering... then on to the 429 for it...my dinosaur is a still undriven 09 identical to my 06- wouldnt hold a candle to a 13 gt500, but I'm hooked on the looks of the 05 still

I wish ford would build a lowend torque monster...anyone thats ever driven a old bigblock can attest to the addictive feel of 450-500 ft/lb off idle, stoplight to stoplight, EVERY time you touch the pedal... high rpm horsepower is fine at the racetrack, power is power...but you cant legally even begin to enjoy it on the street. bigblocks are the only way to fly...with todays tech, they could build a 450 ft-lb @2000 motor easily- even if it topped out at 300hp or had a 4-5k redline, it would be a sweet daily driver... the old bigblocks will probably never be again, but that low end torque curve could easily be achieved if theyd forget the 7500 redline stuff...a optional torque monster would be awesome

What upkeep? I don't have to cool my turbo, like used to be necessary (i.e. turbo timers). Even my 2007 CX-7 said to drive it easy for a few minutes before shutting down the engine after hard running or long stretches on the highway. But my ST has no such statements anywhere in the manual.
I don't have any special scheduled maintenance, just change the oil every 10,000 miles. It's not even special oil.
I think that "more manageable" day is already here.

I'm over 550hp from about 2300-6500. Forced induction over displacement any day.

Direct injection and forced induction is the modern recipe for lots of torque at low RPM.

Cool

I get what ford4v429 is saying, but I think the first and second gear ratios in the transmissions and tall rear end ratios have more to say about the lack of low end torque feel in current cars than the engine size.

I know what 4v429 is saying! Had a 1965 Chrysler NewYorker 4dr sedan weighed 4,300 lbs, had a 413 ci-6.8 litre 360hp-470 ft lbs torque at 2,800 rpms.

Lets say this car surprised more than few vehicles! However I really love my 5.0 it's safer faster well just so much better in every way!

I don't remember if there was an oil change interval on my stock SC, seems to me it was lubed for "life" and the 2.9 Whipple on my car now is okay for 100,000 miles unless IIRC run more than 25 pounds of boost and the blower is driven above a certain RPM.

Forced induction + displacement = Awesome

You can obviously add more boost to catch up but it becomes problematic after a certain point as either the engine cannot handle the added power or more exotic components are required. A favorite tactic in my AO to run big boost involves the switch to E85 as an example.


As always from the perspective of cost and durability the best answer is displacement which by way of example the new Mustang with its 2.3 liter ecoboost engine has embraced.

Which is why I've always entertained the idea of a decent sized performance turbo diesel, perhaps 3-4 liters. Ridiculous? BMW, in a vastly overlooked model beyond a discerning few, but their 3.0 turbo-diesel six in their 335d. It had somewhere around 260hp but 400+ lb/ft of torque pretty much off idle. It was only a touch slower than their gas 335i but with a more accessible power band and incredible fuel mileage -- high 30s on the highway and high 20s city.

I recall that Ford was at one point working on a turbo diesel 3.5 V6 but I haven't heard much about it lately. Imagine that thing, making perhaps 450+ lb/ft of torques at about 57rpm sitting in the nose of a Mustang GTd, all while getting Focus type mileage.

Why would they do a big engine like a 351 or 429? Also, where would they start as a basis for said engines? You're talking a very low volume engine. With the rumors and credible info that Trinity is dead, the trend of big engines is probably going to die with the GT500.

Especially with turbochargers they can get big power out of 4-5l engines. I don't see the need for anything larger.

Well if there is any validity to the Vodoo engine run or the next SE will sport a higher displacement engine which it should since the SVT cars are a cut above the standard Mustang. The PWTA process plus whatever capacity the coyote motor has for increasing the stroke can yield a larger engine without having to add height or weight or drastically changing the engine.

I suspect, giving credence to various rumors, that the SVT Voodoo motor might be nominally larger than the current Coyote's five liters, but only just a bit -- 5.2 maybe? -- and that will be the "big" Mustang motor going forth.

Any GT500 mill might be the 5.2 block but with thicker liners to deal with twin turbos bringing it back down to five liters.

The future will be far more about hi-tech and high efficiency, of necessity, rather than immense mega-liter powerplants requisitioned off some passing tramp steamer ship. However, given the eye-watering performance various Euro turbo four-some-liter V8s are churning out, that may not be a bad thing overall.
