Performance potential of the 5.8L

[RTD]

Curious what people think.

IMO, there's probably at least 50hp to be found in the tune alone on this car.

Probably not a lot to be gained with a pulley as it's already running 15 psi, but should net something.

Likely to be big gains on the exhaust side - an extra 20 cubic inches and 5-6 psi boost, and they're still using that cast iron log manifold and 2.75" exhaust? I bet headers/x-pipe/axle back nets another 40-50hp.

Throttle body and inlet elbow should net gains similar to on the 2011-2012s.

The specs say "upgraded fuel delivery module and fuel injectors". Anyone have any specs on the size of the injectors and whether the fuel pump is upgraded?

if it can handle 19psi

tune/pulley should be around 635-650rwhp for a few hundred bucks.

 

[ON D BIT]

Ford has had it running way north of the crank hp of the zl1 with tune only. That is to say rwhp with a Ford tune was way north of the 580 crank hp in the camaro.

This car will be absolute awesome and amazing. I can't wait to see the times at the track and numbers put down after the mods began on this car. Should be one of the greatest year ever in the history of ford. Lets go racing!

 

[bull3441]

the 650BHP is low balled by Ford. the car has bumped compression, larger displacement and 15 psi on the TVS. the FRPP TVS kit for 2010-2012 is rated 660BHP 2 13psi and very conservative tuning.

 

[chuckstang]

yup this car may do 650rwhp with just a tune haha

 

[ViperBlueCobra]

I was thinking about this as well.

5.4 with a TVS and 15 psi, and less compression is putting out 650 hp at the motor, correct??

5.8 with a TVS and 15 psi, higher compression, I'm thinking should be a bit higher, no?

Or.. is the new factory TVS just a hair better than an Eaton, and an "aftermarket" TVS has extra or better pieces?

Something isn't adding up here. More cubic inches, considerable amount more in boost pressure, higher compression, ford GT cam shafts, and only 100 hp. Am I the only one that is left in questioning this one?

Wow! Name another car from the factory with 650hp stock? Now name one that sells for less than $200k? Yea thats what I thought!:uh oh:

it depends on the aftermarket TVS your talking about. some use eaton rotors and their own case that may be higher flowing, while others are just a straight eaton TVS with a sticker stuck on. even so, i doubt your seeing more than a 30HP difference.

the piece your missing here is the tune. ford can basically put the HP on this thing between 400 and 700(+) if they wanted all in the tune.

 

[IcebourgGT500]

I'm hoping that with a "Tune", the car should pick up another 50 HP. The TVS blower alone on the Shelgy GT500 makes "sick" hp and tq. Can't wait to see some real numbers for the 2013 on the dyno.

I just hope we are not upset when we see the stock numbers at the wheels.

It's the tune and exhaust. An extremely conservative tune (in case some moron runs stale 87 octane) + an exhaust that was designed for a car with 100 less hp = engine not operating anywhere near potential.

An aftermarket tune + long tubes + x-pipe + axle back will probably show insane hp gains, probably 100+.

Add in the rest of the usual bolt-ons (pulley, throttle body, inlet elbow) and these cars will put down 700-725 rwhp easily with the stock TVS. Anything beyond that will require stepping up to a larger Whipple or KB.

JMHO.

I keep reading the rods have been beefed up. That's great news for all those that thought the prior ones good for insanse power was just not enough. Ha!

Yes, they have been.

The new MM&FF mag notes that with the new 7000 RPM redline, piston speeds are approaching that of F1 cars (due to the ridiculous stroke of the 5.4/5.8).

I can name cars that can out perform it.....

Nissan GTR
Corvette Z06

Which are close to this price range now.

then there is the ZR1 corvette.

If hp is all your worried about then I see your point.


After reading everyone's replies. I bet it is in the tune. I can see where they have to make it really conserative in order to offer a warranty.

Can't wait to see cold air, exhaust, and tune will do! :rockon:

With the TVS 2300 you start running out of steam after 700rwhp. The blower struggles to keep up much after that. The 2013 uses a different shaped port then the FRPP blower so that will be worth a few more HP over that offering on the 07-12s(very similar to VMP port). The 2.3l just starts to lose some it's effiecency trying to move much more air. With the bump in compression, displacement and cams the 13 will make more power then the 11/12 with a TVS. 7% from displacement 1.5% from compression bump, 4% from cams. Now this up to the 700-725rwhp ceiling where the blower will start to become the limiting factor. The blower will gain some efficiency back due to the pressure ratio is has high with some of the improvements but it can only move so much air and once the blower stops being able to supply enough air the other improvements start to lose some of their usefulness. The TVS is a fantastic blower so I'm not knocking it. It's easy to become jaded with these cars and "only 700-725rwhp" may seem a little weak but that's awesome for a "little" 2.3l. Lol. Looking at the pulley ratio on the 13 they are already spinning the blower pretty hard especially considering its from the factory.

The most I've witnessed a TVS 2300 5.4 4v make is 820&840fwhp. This was headers, ported heads, custom cams, billet rods, solid lash adjusters, 9.6:1 compression 2.8 upper 10% lower, custom lower intake and spun to over 8,000rpm on a Big Stuff 3 computer. It was making about 3 psi after it was all said and done with.

Nissan GTR
Corvette Z06

I wouldn't say they're the same price range.

The base GT-R is $90k, the Black Edition is $95k.

The base Z06 starts a little over $75k, but that is deceiving. The premium electronics/sound package is almost $9k, the performance packages vary from $4k-$7.5k, and the magnetic suspension is $2500. A loaded Z06 can easily set you back the same $90k as the GT-R.

The 2013 GT500 will be around $60k plus/minus a few grand.

Huge difference between a $60k car and a $90k car.

then there is the ZR1 corvette.

Which starts at $112k and can easily get to $125k.

The GT500 isn't intended to compete with any of those cars. It's main competitor will be the ZL1, and it will likely beat the ZL1 handily while only costing slightly more.

You spoke of hp, so thats what I responded to. Speaking of the gtr and z06 neither one of them have 650hp or a top speed of 200+ mph. At twice the price the zr1 does hit 200mph. You were disappointed with the hp output of the new gt500, you said nothing of the price for performance dollar. But since you brought it up....Ford engineers have tested the new 13 gt500 to be faster than the 05 $150k Ford GT around the race track. Down the 1320 they are about equal. To me this is damn impressive for a $60-65k car!

 

[RTD]

Actually, IMO, the 200+ mph top speed is probably the least relevant stat for the new GT500.

When/where are people going to break 200 mph?

 

[SID297]

The TVS on the 2013 is an improvement over the FRPP one. The inlet casting has better flow characteristics.
