"Horsepower sells cars, torque wins races" - Carroll Shelby

Sorry, again?

The correct statement would be:

"Peak horsepower sells cars, average horsepower over the usable power band wins races."
 
u can keep your lumpy-torque, meagerly-responsive, drowsy iron-block engine. I'll take the savage, relentless pursuit of the redline and electric feel & response that only a highly tuned 'sophisticated' engine can deliver.

Have fun, no one is stopping you. :sly:
 
Easily the most misunderstood quote in the automotive world.

I'd say my fav misunderstood quote went something like...

"So many people think brakes are for slowing down :rolleyes: "
+1 to anyone who can name the speaker. :sly:
 
Think its more of anyone that knows anything about driving in general.

+1 I will keep my V8s :) Granted if they do put a Turbo 4 in the next mustang I would love to get one. At our altitude (5000+ft above sea level) a turbo car might be more fun than a NA car of same rated HP.
 
I don't see the big deal with the 4cyl, I'm sure people can see what they'd be reviving by doing this.

If no one else has said it yet (didn't see it)
 
I also love the notion that a car with less at-the-motor torque cannot push you back in your seat. Torque at the motor is a meaningless number. Power & Gearing pushes you back in the seat. I remember riding in a naturally aspirated, bridgeport 12a powered first gen RX-7 with 5.15 rear axle ratio. You want brutal? That thing was as brutal as you can get. He pinned the throttle in 2nd gear at around 3,000rpm (which is where W&N's car starts running out of puff) and, as expected there wasn't a whole lot happening. It felt about like my stock 13b. The pace quicked at around 5,000rpm as the ports really started to work. At 7,500rpm it felt like a grenade went off and the tachometer exploded all the way to 10,500rpm in what felt like an instant. Accompanying this was this unhinged noise as the carefully tuned intake and exhaust began resonating, and a constant stream of fireballs popping out of the exhaust, as only a big-ported rotary can give you.

You notice the grenade effect didn't come until 7500 ridiculous RPM. Down low that car did nothing - and that's just in second!

@Everyone: the correct answer is Mustang II.
 
Isn't your V6 the same unit as in a mid-'90s Oldsmobile Cutlass Supreme? My family has one of those. If the modded RX-7 is like waiting for a grenade, that GM V6 is like being stood up for a date. But you're probably used to that.
 
I also have a Jeep Cherokee with the 4 liter AMC straight six engine. That engine has prodigious torque from basically idle, and when you pin the throttle it does accelerate pretty good...briefly, but then it's out of guts by 3,000rpm. But in the Jeep's case, the low RPM, lumpy straight six is really a gem, because it feels industrial and strong. Not only that, but it just works so well in a utility vehicle. Putting a sophisticated, high revving engine in the Jeep would be just as crazy as putting an all iron OHV I6 into a small lightweight sports car.

For a Mustang, IMO, the engine should fall somewhere in the middle. A Mustang engine should have strong midrange and a relatively free revving nature, but should also have a torque rich bottom end. The current 5 liter is pure gold. If you haven't driven one, you need to. It's really a fantastic engine.

This. +1
 
Yup. To be honest, I can't see any of the possible engines being anything other than right for the job. The V8'll be good, and modern turbo 4s are pretty good too - lag has been basically eliminated and they have a great mid-range.
 
I hate to sound like an old fart but for some reason a turbo 4 just doesn't seem right in a Mustang.
Truth be told, I don't particularly like the idea of a turbo anything in a mustang. Superchargers seem ok but the old american muscle just doesn't seem to mix well with turbos.

Of course, with that said, I've never really cared for any mustang that wasn't running a V8.

Admittedly, I have a bias with this so I don't really expect to see Ford feeling the same way I do. By the end of the year we might be looking at turbo 4 mustangs using a beefed up focus St engine. Hopefully they will at least leave the sound tube out of the interior so we get real engine noise and not amplified engine noise. 👍

It's still got enough kick to fool people into thinking it's fast, and it probably would be at least slightly so if it hadn't been badly neglected.

(I think part of the problem was water in the gas tank. I just about ran it out of gas the other day. After slight refeulling (I had very little cash on hand), it ran much smoother and doesn't seem to have gotten appreciably worse since. Now I just need to check the spark plugs (original to the car, circa 1993), transmission fluid (frequent gear grinding and gritty, unlubricated-feeling shifts, probably running low), and install new shock absorbers (also original to the car, and make it handle like a drunk buffalo when the pedal is down)).

I agree with this. A Mustang shouldn't have turbo whistle or BOV noise, and it shouldn't have anything less than 6 cylinders - for the poser not-quite-a-real-Mustang variants. If you want a force-fed Mustang, use a supercharger. Less lag, less peakiness, and spur-gear noise is one kind of whine I certainly don't mind. A roaring V8 with a supercharger screming away... man, that's musical.
 
While I wouldn't buy a V8 Mustang, I would consider a Turbo 4 'Stang with a manual gearbox. It would, in my eyes, be a somewhat cool car, unlike the retro V8 Mustang of today. And nobody really wants a V6 Mustang.
 
A turbo 4 cooler than a V8?

I'm actually speechless. What would even drive someone to think that?

Also, mufflers are evil. Watch this:



As you can see, not only do the mufflers cover up that throaty V8 rumble with something significantly smoother and more sedate (seriously, how much effort went into making that car sound boring? Serious question), they also block off those tasty backfiring noises.

Somehow, somewhere, there's a muffler design that cuts volume just enough to satisfy regulations without making the car sound too smooth.
 
Yeah, it'd be real professional for cops to roll around with their cars sounding like that.

I didn't say it had to sound exactly like that, though it could provide an effective deterrent. However the stock mufflers on a Crown Vic are so sedate the car barely sounds like it has a V8. Most cars aren't much better. So the question still stands, how much effort is put into intentionally making cars sound boring?

The realisation that a turbo 4 would weigh less, making the car handle better, would get better fuel economy than a thirsty V8, and would make good low end torque.

Yeah, it'd be real professional for cops to roll around with their cars sounding like that.

I agree. It doesn't sound all that nice to me, just ridiculous and unrefined, not to mention immature.

You have to realize that the typical crown vic buyer was either a government agency, a fleet service, or an octogenarian.
