Rumor: SAE testing complete, numbers "north of 570 HP"

The only way I see it hit the magic 600 mark is if both the LSA and the LS9 get a power bump. Even though a 600hp ZL1 wouldn't touch a ZR1, marketing still plays a big role IMO.

I've said since before the debut of the ZL1 that this car would make 575-ish horsepower, might as well stick with it.

Umm ... thats not what I was saying at all ...

What I was trying to say was that what we think of as 'engine ratings' aren't really engine ratings, its the rating of the engine minus the losses from the intake, exhaust, accessories, and emissions equipment. This is true for any and all engines that use a net rating (vs gross rating, like what was done in the 60's)

By changing some of that other stuff that is taken into consideration under the current SAE net testing, you can change the rated output in a for a car without doing anything that changes the engine itself (such as upping the boost, changing the cam, altering the compression ratio, etc).

So how do you outrun a Shelby GT 500 with 650 HP when you have been given at least 80HP less to start with?
Or is the 650 HP not confirmed either?

Simple, he sits at the line spinning his tires

and 650 isn't confirmed, nor is 620, nor is 600 ...

Everyone is always saying the GT is traction limited,
Do they not have tranction control or any kind of launch control?
This is a serious question. I know nothing about mustangs.

They do have some sort of launch or traction control and not knowing what other changes will occure for the 2013 GT500 it is hard to say how it would hook. It is a known fact and most current GT500 drives will tell you, stock it is hard to hook with the solid rear and 285s otu back ...

That is one thing I was glad to see stated on the ZL1 ... 20x11s w/ 305s out back ... Ford needs to put wider meats on the back of the GT500 as well..

575.

.....but keep in mind guys that the LSA does not have forged everything like the LS9. Talk of over 600hp is great, but it is still a LSA not a 638hp LS9.For those that think it will make over 600hp you are going to be disappointed.
It will be between 575-585hp and that's it.
The aftermarket will take care of the next 100-150hp just like they already have with the CTS-V.
Also remember that this car is going to get terrible gas mileage. The next gens will be twin turbos with smaller displacements and much better mileage.

[b4z]

The CTS and CTS-V has more restrictive intake and exhaust. LFX will make 323hp in the Camaro and only 318 in the CTS. There is 10-15 hp for the LSA right there, and any other changes to the intercooler, etc. will pick up more power.

[Orbit Orange]

I'm going with a few others who said 575 HP.

Think about the statement for a second. North of 570 HP. If it were 580 something they would have said north of 580 HP, if it were 590 something they would have said North of 590 and so on.

It is going to be somewhere from 571 to 580 HP SAE rated if this rumor is true. Wonder when the actual number will be announced.

I've been thinking CTS-V and ZR1 WILL be getting a bump around now. With ZR1 knocking 6-or-whatever seconds off it's 'Ring time, I have to think they've been tinkering under the hood in addition to their chassis and aero' tweaks. IMO - this leaves the door open for ZL1 to get close, and maybe even a little more than 600. I'm almost willing to be if we do see increases for those cars, we're going to be very close.

Better traction That'll hold him off for a while.

What worries me is that we're getting the same tires, only an inch wider, so I hope that IRS, MR, and PTM help ZL1 hook better.

I wonder how much of a pain it would be to get 315s on those wheels. I know 315s are pretty popular for 11s, and know that Opp' said these are about as wide as they can go, but I think 315s will fit Others here have gone wider

But LFX has different heads and cams, in addition, doesn't it?

Or... they want everyone to be really impressed and surprised I admit I'm not confident in much more than 580, but know that they've really surprised, at least me, with the rest of the technology that they're stuffing in that hog, so who knows? We'll find out in a few months I'm sure

I bet 315s would fit just fine .. also if I remember correctly, these will be 305s on 20x11 wheels vs 275s on 20x9 wheels ... That should hopefully make the contact patch a bit wider even w/ 305s

Handeling should be that much better with 20x10s up front and 20x11s in the rear (vs 20x8s and 20x9s).
