Difference between S/C 8 and Turbo Barra

[lovford]

Maybe a stupid question, but can the pulley on the 335 be downsized to make more power. From what I have seen it already looks very small.

Depends on RPM.

Power (kW) = Torque (N.m) x Speed (RPM) / 9.5488

[lovford]

I'm out of my depth here, but I think KW is a cars top speed and torque is how fast the car reaches that top speed.
There both fantastic cars. One makes a nice noise, that's why I bought a v8, and the other is a stealth fighter. There is no even winner.

As you were everyone.

True. But it's a known fact, that in stock form. The Turbo F6 is quicker than the S/C 8. However if you tune both cars with no other supporting mods. The S/C 8 will be a lot quicker, than the Turbo F6.

If I’m reading the graph right, that would be true only over 105km/h. So up to max legal speeds (NT aside) the SC8 wins hands down.

But to answer the original question, One is a charged monster that sounds great....and the other is a T6.

Really, where’d you read that? On the internet? Must be true.....

The SC 8 is quicker to 100 than an F6 and is easier to get off the line to boot (4.9 v 5.1). 1/4 mile times are also around 0.2s in favour of the 8.

The 8 is repeatable fast but the F6 needs practice to get off the line quick. Common complaint from F6 drivers who get handed their backsides is “I couldn’t get it to boost off the line”. No such issue with the 8.

Alas, they are both no more - instead we get the slower Mustang as Ford’s “Performance” flagship. I suppose it is when compared to a Ranger.

Dyno runs are done in 4th gear. So....

if it's making the same torque at the same rpm, then the power will be the same

ie The points were the red and green lines are the same - in this case, that's at 105km/h.

[solarite_guy]

It also crosses up top and both seem to emerge from the same point at the bottom. Seem to.

A lot of people think that, but it is not true.

Power (hp, kwh, etc) = work
Torque (lbs-ft, nm, etc) = force

This may not make sense, but it is possible to make 1,000,000 lbs-t or nm of tq and yet make 0 hp.

HP to the ground is what gets the car/bike, etc to the finish line. That said, mph is related to hp. So that part is true.

By my calculations using the metric torque formula at 105 where both cars are equal;

Torque = 608 Nm
Power = 190 KW
RPM = 2980

True and yet Trucks have always been rated by the amount of horses they have

The 2018 Mustang auto can get to 100 in under 4 seconds, with a high 11 quarter mile. These times have been recorded in private hands. Both times are easily faster than either a Miami or Barra 6.

It was the case of the 2015 Mustang being slower than both.

No. The information I got was off this Forum (AFF). You should look it up some time. That way you don't make your self look like a dill.

Stock NA.

[arronm]

MMMmmm doesnt really leave much room for easy mods. Cant even crank up the boost. PASS.....

Looks like a nice car though...

Yep, this forum is on the internet..... not sure why you think I look like a dill when the info I posted is correct for stock cars as tested as independently as possible by noted car reviewers. A hand timed 0-100 does not count.

Add half a second to that mustangs time as Americans use the one foot roll out technique when measuring times they also only go to 96km (60 miles) not 100.

Even so if the new mustang hits hundred in around mid 4's down here on Australian soil it is still almost a second quicker than the pre facelift model. WOW

[ratter]

and Australians only race to 400 mtrs ;)

Big changes from the 2017 model tho , 10 speed auto and direct injection (at last)

They did make it, they just threw it in the bin.

Yeh these turbo V8s are crap..

[roddy1960]

The key word here is 'difference' I think.. I'd be respectfully suggesting that both the Turbo and the SC V8 are inately different locally bred beaut Blue Oval beasts . The owners of both would know only too well why they choose the Barra over the Miami and vice versa including how they feel toward them.

Suggesting the different performance characteristics and scope for upgrades and tunes would be a key reason why they choose one over the other.

I'd have a hard job trying to decide either way . Maybe it's a good thing that I'm not likely to be financial enough any time soon to ever contemplate joining the Barra Turbo or SC V8 ranks so I'll just go to sleep each night while my NA XR6 and ol' faithful AU ll sit quietly in the shed and car port ready for the next day .

Well supercharger kits are everywhere for it so it's not like it's hard. Bit expensive though.

But NA with some bolt ons and tuned for E85 one has made 501rwhp so there's still some left in it in NA form.

The turbo is subtle, then unleashes like a crazy person, the 8 is forceful but more mellow until it hits around 80, then it squirms and goes balistic. These are the facts as i have experienced them.

Anyway no point in the whole arguing on the internet thing, doesn't change my experience anyway so is largely irrelevant.

To be fair, the comparison really should be Sprint to Sprint as the cars are the most similar to each other. Same tyres, same tyre width, slightest weight difference, slightest power difference etc.

That being said, of all the comparos I've seen, it's pretty much split down the middle on which is quicker.

[ratter]

V8 sprint has different size tyres to the turbo one doesn't it?

What who got that much na ???
