GT350 1/4 mile

[Erik427]

Please look up the latest VW news and you will see what I am talking about. Ford cant sign up for one set of settings/standards and then deviate from them.

Ford advertises absolutely ZERO different between the engine/output between the GT350 and GT350R, meaning they are likely bundled together under the same set of emissions testing and fuel economy standards. This is not just with the EPA, but at the state level with local agencies (mainly CARB here in CA which more and more states are now using as a bench mark). So ford cant tell all of these government agencies one thing on how the engine will perform and then cook the books for a handful of cars to "sand bag". They stand to gain very little from this sort of tactic and could be fined or completely banned from selling the car if they are ever caught.

If there were a measurable output between the two cars (and 24hp is more than measurable), ford would mention it, period. If the car is under-rated, that is one thing, but it would apply to all of the GT350s made

As I said before. Ford most likely passed the emissions test at the 550hp mark then detuned it back to 526hp. Much like the 465hp LT in the Vette. Base version gets 455hp. Camaro gets 455hp. Are you saying Ford cannot do the same?

I want an FPC voodoo in Factory Five kit car or something under 2500lbs. I need that kind of rush right now.

I want to see something like Coyote stock but with a Voodoo swap!

Has anyone seen the Road and Track review for the Shelby GT Super Snake with 850 hp? I can't believe they only managed 3.9 s to 0-60 and wait for it 12.3 s quarter mile! 12.3 s on a freaking 850 hp monster:doh:

Something must have been gone south. There is no way!

Yeah, R&T said that too. Even with poor traction the mph is usually indicative of hp, and at 113 mph it's probably not making anywhere near 850 hp.

Thats what you call a shitty driver.

It's hard to imagine it could happen this quickly, but with Carroll dead I think Shelby is sliding downhill fast. Maybe the testers got a bad one, but what I see is the car not making the advertised power number. Unforgiveable in my opinion - to sell a car at that high a price and not make the advertised hp.

To be honest Erik, I heard they were sitting on close to 550hp and 440tq but it was fuel economy that held them back... not emissions...

I feel that Ford will drop the 5.2 down to a 5.0. I initially believed this would be done by simply decreasing the bore. It would be the cheapest way... Although, many argued that the Voodoo would benefit more by reducing the existing stroke... a more traditional route... I spoke of the potential benefits on here before.

Not only do I think the current Voodoo is capable of 550/440, I believe the extra .2 liters was final for a few reasons.

1.) The stock stroke of the Coyote may have needed the extra clearance.

2.) The initial R&D cost was already met, a short stroke Voodoo comes later.

3.) Cheaper power with no Direct Injection/Dual Port Injection.


Once Dual Port Injection is ready to go, I believe the stroke will drop as will the displacement. Depending on how much power Duel Port Injection adds, I'm debating if they will try a 289/4.7 liter. The 5 liter FPC is a HUGE milestone that they likely won't abandon.


The goal here now is beat the Gas Guzzler Tax and save the Customer the $1600 (to reinvest in the model more likely). The Dual Port Injection is probably worth another 25hp, the RS uses it I believe. We may see a solid 40-50hp bump and only lose a little dropping to a 5.0...

The RPM's could reach 9000, we could see a 550hp/450tq outta the Voodoo Child 5.0 bud... and it could free up $1600 extra R&D dollars with a 26/31 Hwy/Cty MPG rating.

Thanks for posting that. Interesting thoughts and speculation.
Two things:
1. Yes it should be able to make closer to 550 hp. Hopefully the power is slightly underrated at 526 if anything.
2. Voodoo Child - I love it!

I can guarantee the motors make more than 526HP. When the cars get on the chassis dyno I think 450whp will be the norm. But I won't be a bit surprised to see 460-480whp. Now some dynos are more generous than others. And even on the same dyno some cars are just stronger than others, so there will be some variance. But most performance cars nowadays seem to have a nice margin of error built in to insure every car makes advertised HP.

I hope you are right.

I would assume Ford played with different tunes and tested engine longevity with different tunes. I would also assume that if they are rating the engine at 526, most engines off the assembly line should make at least slightly more than that (5-10 hp min). IMO any performance manufacturer should be working hard to make sure EVERY engine surpasses the rating and no engines are slightly low.

Still think we are looking @ 11.7 1/4 mile times on the R . I kind of wish Shelby American would take a break with the super snake until the next GT 500 is released. Road & Track article is not what the Shelby name needs. I agree with Hack that things seem to be sliding down hill over @ Shelby American. The average joe doesn't know the difference between the Shelby coming from Ford or Shelby American. They see the name on the car.

Or Shelby American can try and take the customer seriously. Why not try to be a legitimate 3rd Party supporter of the Mustang? Steeda and Roush have always offered some of the best 3rd Party support and the parts were a legitimate upgrade.

There is absolutely no excuse why Shelby can't compete with Steeda as far as performance and quality.


They said at one time they were developing the GT350R-S for SCCA (Paul Brown and Tiger Racing did the Boss 302S). Maybe Ford went with another company on that...


If I were Ford Motor Company, I would be interested in Shelby American as a whole. The "Shelby" name could be a nice sub-company of Ford where things like the Cobra Roadster, GR-1, Ford GT and some other high end cats could R&D at. Roush is currently involved like this to some extent... Multimatic as well...

:headbonk::headbonk:

You are really missing the point, advertised HP is one thing, emissions and fuel economy is a completely separate thing. And its not as if there is some base line "test" to pass and if they do it once, they can deviate from that and do whatever the hell they want. It doesn't work that way with the EPA. If the motors were fine at 550hp, why wouldnt ford just release it as such? What do they really stand to gain from that?

At this point I think you are talking 100% out of your ass, not a single thing has mentioned any difference in engine tuning between the two cars.

That's what I'm waiting for!!....hence the handle!!

 

[krt22]

Maybe a mach 1 in the future? Might be slightly detuned though of course.

Brands are allowed to underrate their motors. GM is doing what I just described with the LT1 spread out over three different cars and two chassis. BMW makes at the wheels what they are rated at the flywheel. Please explain how the epa handles this? BMW? The Vette? Trust me....the GT350R is very close to 550hp. Remember, Ford did state that the R will make a "few" more ponies. If what you say is true about the epa? Then why is Ford not saying what the R makes?

Please reread my post one more time. Stated HP is not the same as emissions/fuel economy.

And please post where "ford said" the R will make a few more ponies. And since when is a few 24?

I agree it can be under-rated... and hopefully it is.

I haven't seen anywhere that Ford says the R will make more HP than the regular GT350. Everything I've seen says they are identical. Could you post where that came from?

I'd like to see that too. And not "they are slightly different due to resonators vs. no resonators". That's not going to make enough difference to notice. Now, the CF wheels will make a noticeable difference though.

Never seen this either and I'm on the forums every day.

I tried my best to get an engine and controls pack from FRPP to swap into our CS car. No Dice.

Nobody has. That's because it simply hasn't been said by anyone reputable. Dave Pericak said that the R would make a little more because of the resonators being removed, but they weren't going to change the rating on the R versus the regular. That's it, and that's all that's been said as far as a power difference.
