^{With the extra displacement, TVS, higher compression, and extra boost for this motor, the "650" HP rating makes me think of the "375" HP rating on the 69' BOSS 429, just a "tad" conservative!}

^{I'm thinking just north of 600, I'll say 605 WHP.}

^{I sure love my Alloy 08 but I think I have the bug for a 13!}

[Shipwright]

I say 580rwhp.

[Agas Ride]

I'll Play, 582 rwhp..

[CANADA GUY]

I'll Play, 582 rwhp..

 

 

585 rwhp- will be closest ( finishes off at about 660- guessing the 650 hp is conservative)

[xjrguy]

618 RWHP

[mustang let back]

580

[darthracer777]

432.5 kilowatts !!!

[Dennis Brown]

613

[ChrisSD]

Some of you guys are dreaming. The engine will most likely be SAE certified, which means they can't "under rate" or " be conservative ".

 

Also - all dynos read differently, even dynos of the same make and model. I'd wage 550ish on a Dynojet, and 510 on a Mustang Dyno SAE corrected rwhp.

1. frydguy79 609rwhp

2. Carnut12- 603rwhp

3: Kona/Phill; 680 at the crank minus 15% for parisitic loss so 578 rwhp.

4. MonsterPost - 598.2rwhp

5. JeffJ - 572rwhp

6. Crushinator - 555rwhp

7. jfreemanmd -- 590rwhp

8. Cobramach1 - 571

 

Too funny. I was going through the thread and I picked 572 and was going to post that and then I saw JeffJ picked 572 (My name is also Jeff J) and I thought that was really funny we both picked the same number! So as not to pick the same number I took 571.

[hourigan218]

I'll say 591. Don't know if it's been taken, if so I second the motion.

Nice choice!

[speedyman]

Peak horsepower numbers can be decieving and not allways a great predictor of street performance. Torque wins races, scares passengers, busts balls, and generally makes a muscle car what it is. Compare the torque plot and area under that line between the TVS 5.8L and previous stock configurations. This will give you a far better idea of what one will feel in their street driving experience

[Bill Hamilton]

This months HOT ROD Magazine has a nice article plus a cover shot of the 2013 GT-500. There's an engine dyno shot showing the needle sitting on 650 hp and in the article they say they saw in hit 670 at one point. Again, this is out of the car and sitting in an engine dyno. The exhaust headers are glowing red in the photo.

 

I'm sticking with my original 567 at the rear wheels. B)

You're way low Bill. It will have even less drive train loss than the current GT500 with the addition of the carbon fiber DS and the gear ratio changes. I'm gonna go with the high side and say 608 to the wheels.

[hawkbarr]

583

[BluFury]

611

[0201212]

I'm thinking 587. Either way it should be a nice monster stock.

A carbon fiber driveshaft and gear RATIOS don't affect parasitc losses. Dyno pulls are ALL done in the 1:1 gear (4th in the case of a 2012 and earlier GT500). Gear DRAG is what causes parasitc loss. That's primarily the gears in the rear axle since the transmission input and output shaft are locked together in 4th gear. The only "gear drag" in the transmission is from the Counter (aka 'cluster') Gear that is still being turned off of the input shaft so tranmission gear drag is minimal. There is however approx. 2% clutch slippage at ALL times along with the rolling resistence tires create. Add the draw your Alternator takes (about 5 HP at any given time), your water pump takes, your power steeering pump takes (which is NO LONGER a issue with EPAS) and you have your "15% rule of thumb" parasitic loss.

 

There is however some parsitic loss from U-joints and/or CV joints on the driveshaft (along with the angle at which they turn). With one less joint (and center carrier bearing) in the 1-pc. driveshaft used on a 2013 there will be a TRACE gain due to a every so *slight* loss of parasitic load (due to the DS you mention). "Trace", meaning it won't be measurable.

That's in line with something else I've read about 17% loss using SAE numbers on a manual transmission. However I've also seen 2011-12's rated at 550 hp SAE doing on average 480 rwhp. That's about a 13% loss. Guess we'll all have to wait till April to find out. B)

Well ya gotta remember, in 2011 they started using Electric Assisted Power Steering (EPAS) as opposed to the old conventional Hydraulic Power Assisted Steering where the engine had to drive a hydraulic pump to get hydraulic pressure from.

 

That alone may explain the difference of ~2%.

Can you snap a pic of the page that the photo is on or scan the entire article?

Here's a quick pic of the page I was talking about. I don't have a scanner where I am now so a camera shot's the best can do for the moment, sorry. It's a pretty lengthy and good article.

[supersnake94]

that looks pretty sweet. I should go and pick up a copy of my own.

I guess the gear ratio changes won't be felt on the dyno and the carbon fiber DS with one less joint will have next to no impact. But I'm betting you'll sure feel the difference in the butt-o-meter. The car will now run to 60 mph in first gear and I bet the carbon fiber DS lessens load load shock. I still believe they will lay down 600+ to the wheels. If not...nothing a pulley and a tune won't solve.

Oh, I *absolutely* agree. They flat-out said they changed the (tranmission) gear ratios to soften the launch (e.g. to get quicker 60' times).

 

The biggest mistake I see many many MANY people making around here is LOWERING the rear gear ratio. With forced induction, you want to RAISE the gear ratio in order to take advantage of the increased Torque a Super/Turbo Charger makes.

 

I think the '13 is going to be a rocket. Ford has taken some of the "driver" out of the equation by making the car easier to drive in a quarter mile. One less shift over the 1/4 mile and only ONE shift to the 60' mark. Quicker 60' times equate to lower ET's, PERIOD. One less shift in the 1/4 equates to quicker ET's too. A higher redline will make more Horsepower which equates to higher Mile Per Hour in the 1/4 mile. Then add more displacement and a bigger blower (for more boost with lower Intake Temps due to less Blower RPM).

 

All in all, this car should be a BEAST at the drag strip. And let's face it, numbers sell!
