Yes, that may have been a bit harsh on my part. Mr. Scrappy, I mean no disrespect.
I, too, used to think the LS motors were old tech dinosaurs. As I've aged and overcome my earlier bad experiences with GM cars (a 1980 Buick Skylark in particular), I've come to appreciate them. It's hard to argue with the results.

Not sure if as durable, but mine was flawless while I had it. I never performed a 100k mile durability test. So we will never know. Not as clean and got lower mileage. Yeah, I concede those two points. I guess the total engineering might and resources of GM had a 17 year old on Pizza Hut Salary beat. Guess they showed me! The only notable innovations the small block has really seen is in the materials and emissions department, from an all time low in 1977, to an all time high today. If that impresses you, then great. Liking the LS engines is not hard to do for most people. They check a awful lot of boxes and do a bunch of things well. But on a list of most desirable engines, they are not in the top 30 for me personally. |

I forgot where I read it, but it looks like the EcoBoost 4-cylinder model is going to cost a little more than the N/A V6 model, then will come the GT with the supposedly unchanged 5.0L. And there is still speculation about this unknown smaller-displacement high-output EcoBoost V6 codenamed "Nano"; it would be nice if that were the 6-cylinder option instead of just bringing back the N/A 3.7L.
On a side note, the Cobra Jet just got an EcoBoost TT setup. Since the fate of the Boss 302 and GT500 are undecided for the 2015 model, they should use the EcoBoost 5.0 in the next generation GT500 in my opinion. |

I don't think the GT500 is destined for a twin-turbo setup. Sticking with a supercharger is much more likely. |

I agree, the Mustang has never really been an automotive technology leader...it will probably keep the same formula for another decade.

Exhaust turbines are thermal waste recovery, and two compressors (twin turbos) can afford to be smaller each, and push the same combined volume in total. Since they aren't taking power from the crankshaft, only adding to it.... all added power is net added power. If a supercharged 600hp V8 is using 100hp to turn it's supercharger at high engine speeds, where peak power is... it is actually stressed like a 700hp engine, but still outputting 600hp as a system. A turbocharged 600hp V8 is not using 100hp to mechanically turn the compressors, waste exhaust thermal energy is doing that, rather than being wasted. The penalty of exhaust backpressure on the fluid dynamics of the engine is less than the mechanical power demand of a supercharger at peak RPMs, and the net gain of turbos are usually higher than the net gain of superchargers at higher RPMs. If the turbines were mechanically compounded, rather than driving the compressors directly, they would be adding waste thermal energy as power to the engine mechanically, to more than off-set the mechanical subtraction of a supercharger... Like engines in some variants of the P38 Lightning. But that is another matter. With Ford's V8, like the CobraJet project, The engine with direct fuel injection becomes part of Ford's EcoBoost family, if they choose to market it as such.... but a TT-V8 isn't exactly a greenie poster-child engine. It might be more fuel efficient per horsepower than most other ~600hp engines, and possibly even run on regular fuel, though... It is not as if a 5.0-5.4-5.8-6.2 V8 is suffering for low-end torque as-is. If anything, supercharging the V8 makes the current GT500 less-useable, as the throttle has to be feathered all the more, to keep the rear tires from going up in smoke if you sneeze while your foot is near the pedal. Too much shock to the rear tires is not beneficial for traction, and positive displacement blowers sometimes have a hard time keeping up with the engine at higher RPMs. Low end torque is even less of a problem with DI's allowance for higher static compression ratios to act more like an atmospheric high-performance engine when off-boost, and making less peak boost pressure make more of a difference. If exhaust system packaging isn't too difficult (EB V6 seems not to have much problem) and maybe with air to liquid charge cooling in the intake manifold, (which they might already use for the Supercharger...) I can see how twin turbocharging the next GT500 would maybe be preferable than positive displacement supercharging. But I agree... Boss 302 should be the best atmospheric 5.0 V8 in Ford's catalog. Maybe they should do a Boss 380 drag-race special, with a twin-turbo 6.2... Sort of like a modern Boss 429. They could share that engine with the Raptor.

I guess somebody should tell the top fuel guys that they should not be running Superchargers.
Superchargers take a whole lot of power to turn, but they almost always give FAR more than they take. Designing the engine to take the stresses is just a matter of design choices. Superchargers also have the benefit of being positive displacement and have immediate throttle response, where as any turbo system is not as quick to respond. The BOSS needs to stay NA or if it must go FI it should be supercharged. Predictability and responsiveness are what make for a great track car. Turbos would not improve the BOSS no matter how more 'efficient' exhaust scavenging is. Also I would like to put my plea for you to stop suggesting that directly connected turbos using exhaust gasses to power the crank directly would work on a street car. An 18 or 27 bank radial engine or a monster V12 used in WWII planes is not the same animal as a street car. These engines do not work in the same environment as car engines that are on and off the throttle all the time. WWII had many novel ideas that work well at 30,000 feet on turbo/supercharged engines. They are not applicable to car engines. So please that idea is not feasible. |

Wasn't saying that a mustang or any other car engine should be turbine compounded, but I don't think it is as bad as you portray.
I was talking about the differences between how superchargers and turbochargers work in general, and offsetting the kinetic drag of a supercharger. You criticize something not being similar, yet you draw a parallel between road car superchargers, and a Top Fuel dragster? Top fuel isn't a road car in any stretch, and a multi-thousand horsepower engine that goes a quarter mile at a time from a standing start, with gigantic drag slicks, might just want the ultimate hole-shot power of a positive displacement supercharger larger than most street legal car engines entirely. Mustang Shelby GT500 is already criticized, Super Snake even moreso, for being dangerous if the driver is the least-bit careless with throttle application, because the tires can't keep the car under control once the engine breaks traction. Probably more violent at breaking traction than a ZL1 Camaro, or an SRT8 Challenger. Perhaps maybe even less traction than a V10 SRT Viper with the engine and driver more balanced between the front and rear tires, with less of a front weight bias than the Mustang, and truly massive rear tires. If all one wants is burnouts, and replacing very wide rear tires VERY often... and risking the car careening out of control... have fun with a positive displacement supercharger on an already large-ish V8. Or, jack up the car on gigantic racing slicks, and keep an expensive Mustang on the drag strip, rather than driving it in the real world, and fish-tailing it into a tree.

I really like the front end of this old concept that was floating around a few years back:
Unfortunate it never made it into production. |

It actually did make it to production... that was a concept made by an Italian that ford helped and used as a basis for the current gen mustang (starting with the body after the 1st retro look). Plenty of design queues were taken, and it's good looking! But I bet the next gen mustang will be even better

I wouldn't expect to see a BOSS re-appear at the beginning of the 2014.5/2015 (whatever they call the new "world car" Stang) run either, as the hype around a total re-design will drive sales of the regular models for a couple years before they start bringing in the SE models, if history serves. It's interesting, as there's been a SE model to "send off" each generation for the past few; new-edge had the "Mach 1" w/ the shaker hood, and the original retro S197 had the Bullitt cars in 08-09. AFAIK, there's no special editions known for 2014 yet, though there is a unique "Appearance Package" being offered on both V6 & GT cars for '14. |

Just to clarify, in my post about an EcoBoost 5.0, I wasn't saying the Boss should get it. I was really just saying it's a good candidate engine for the next generation GT500. It couldn't hurt since it would really just make the car more fuel efficient than the supercharger setup while maintaining the power and modability it currently has.
I, too, would like to see a special edition come out for either the current or new generation. A new Mach 1 or Bullitt would be pretty cool. |

There are plenty of 4 valve pushrod diesel engines, but obviously they rev much lower and the combustion system is completely different.

I suspect that they're just trying to keep it under wraps by retrofitting as many previous-generation body panels as possible onto the new car. The proportions of that nose seem somehow different from the current generation, and I doubt that they would leave the sides and tail as-is.
