Yes, but they are referring to comparison with the 04 GT iron block. The Al block will be new to the GT.

At least that's what I read into it. I may be wrong.

 

Underrating may occur........look at what ford did with the F-150 and GT.

They said 9500 lbs for F-150 and then they said wait n'm we lied its 9,900 lbs.

Then GT was 500 hp.....then Vett 6 with 400 then Ford with 565 hp on the GT.

So maybe Ford will do the same with another auto icon.

325hp?! Wee!!

Actually I was talking to a guy who use to dyno cars....he goes to my church and he said parasitic losses are about 10%.

 

Depends on the car setup...10% maybe for a Front wheel drive manual....
15% for a RWD manual
20% for a RWD auto
I don't even know the number for AWD cars, but I do know that they have one of the worst losses before it touches pavement.
etc

The percentage depends on what the power has to go through before it hits the ground.

 

15% is a conservative and often accurate estimate of mustang drivetrain losses.

I still say 325hp at the crank.

 

I say the next Supercharged Mustang is a BOSS

At least I hope so....


Don't forget, there is always the use of Shelby GT350, GT500 and GT500KR

And of course a MACH I in there somewhere too, life is good in the Ford Lane these days.


Our time has finally come............

 

kev you made a good point here. I remember reading some where when they were testing the 5.4 S/C motor for the Ford GT. That the SVT guys said you dont do this much research and certification on one engine for just 2 vehicles(Ford GT and the 06 Lightning) and that it would see operation in other vehicles. So a 3v 5.4 engine would not be that big of a surprise there!

 

But hold on a sec, the Ford GT has a 4V 5.4L, not a 3V. No word yet on what the new Lightning will have, but the concept obviously did have the 4V (not that that means anything for sure).

 

Yeah, true, lotsa guys grenade stock motors with too much boost. But really, that's because the hypereutectic pistons and powder rods just can't handle it. With forged internals, you can run serious power before problems arise. Think about it, you rarely see a block let go. It would basically have to rip the mains out. You just don't hear about that happening with these deep skirted, crossbolted mod motors. I've only seen a couple destroyed blocks, and even those were because the internals let go and punched a hole in the side.

 

As someone pointed out "new" could just mean "new to the Mustang GT". The part about the block being strengthened could be refering to the changes made from the old "Cobra" blocks to the new high volume one, which we already know are indeed stronger.

However, thanks for the info. It could well be a new design. They make incremental changes to the blocks all the time. They then filter them into all the other models. So this new one could show up on the GT first. We'll know as soon as they hit the lots and someone checks casting numbers, or maybe earlier if the parts dept guys get the list before that (and the # remains the same).

 

They could also be using the new Aluminum alloy that the GT block uses. I guess we'll know more later.

 

Carrol Shelby better start developing some, that is, if he hasn't aleady

Yeah but they are modular motors with most of the components being interchangeable. And they do have a 3v head on the F-150 already so why would that not make sense for a SE like the mach 1 or boss?

Again this is all speculation and we will have little to no proof of anything for atleast another 6-9 months minimum unless ford lets stuff slip out.

 

I here ya. My only point is that when Coletti says (and I'm quoting your paraphrasal):

"you dont do this much research and certification on one engine for just 2 vehicles"

He's talking about the motor in its entirity, save for exhaust and other minor things. He's not talking about a motor with completely different heads, because such a motor would still need to be R&D'd and certified independently of the 4V GT motor.

 

20-25%, depending. I almost purchased a '92 Dodge Stealth twin turbo (wish I had, now, it was a great deal ... only 36k miles, perfect shape) a month or so ago and was doing some research. Those cars were AWD, and while rated at 300hp, actual HP at the wheels was anywhere from 220-240 on dynos. That's a little misleading because AWD gives you some advantages on takeoff and such, but the loss is significant.

 

Superchargers are good for an extra 100 HP so maybe the stock GT engine really makes more than 300 HP.

 

My buddy had a Stealth Twin Turbo. Thing was wicked fast. I don't know about drivetrain power loss, though. You sure didn't feel it 'cause the thing launched.

 

Ford just announced that the 2005 Navigator will have the 3V SOHC 5.4L in place of the 4V DOHC motor.

I'll bet that most FoMoCo vehicles are going to get 3V heads. Only a few select vehicles, like the Ford GT, Shelby Cobra, Cobra R and maybe a couple Lincoln models will have 4V DOHC engines in the future. Everything else(including the SVT Mustang Cobra) will get 3V SOHC heads.

Ford also announced that the 6.4L V10 truck engine will get 3V heads for 2005
So let's hope that we will see a low deck 5.8L, 3V SOHC, V10 engine in a future Mustang SE. :worship:

 

I think it is easier to make more torque with the three valve heads which was the biggest complaint with the 2V motors.

 

More hp, more torque, broader powerband etc...because of better flow. The VCT plays a major part in this also.
