I hear you on the speedo inaccuracy...meaningless data.

<edit>...of course, tachs are also usually pretty far off of real rpm's, as well.

 

And oh so responsive...  :)

I've shut off the engine, pulled the key out, and looked up to see the tach still coming down - talk about lag!

If you really want to know if the 6,500 RPM deal is real, throw a DL1 in the car, hook  the tach signal to it and then bang it off the rev limiter in 2nd. Look at the data and the truth will be told.

If it really does go to 6,500, trade in the RX8 Mike .

 

 

I have 11 months until the RX8 goes bye bye...plenty of time to figure out what's what...of course by then, Ford will probably have released at least two more Mustang "specials" with more to come...seems like every week there's either a new package or rumors...

In slow, out fast.
In fast, out backwards.

I drove my CS half converted at a few autocrosses before I received my calibration tool in the mail.

When I installed the CAI and re calibrated my car , I promptly spun the car at the first autox I went to. ( My co driver who drives a Z06 did the same thing. ) The car was VERY different. It was more responsive and I feel at rev limit it banged and didnt have AS much drop off in power. As for when I hit rev limit in the old setup, it was like dropping a boat anchor.

 With each part I added the car transformed. Granted, I am relatively new to this sport, but the differences in this car to when i started are staggering. The FR3 suspension pack is amazing on the car. Unless its all the same parts ( which  I agree with Sam, I don't know why Ford would do that, make this car exactly like the SHelby save for a different gear ) I would want more clarification.

Besides, whats wrong with building a clone, its fun, and you get real intimate with the parts. I should work for Ford Racing, Im like an AMWAY salesman when it comes to extolling the virtues of Ford Racing parts.  

 End of the year deals on California Specials could probably get you a good Cal Special and a deal on all the necessary parts ( which I  could tell you, and Sam  could sell you )  for around 27.

Same wheels the black Shelby's get (and I don't like them either).  Luckily you can change them easily.

So..... looking at the pictures, I can't help but notice the redline is still about 6k RPM.

Sammy, I guess those eyes of yours are much better at seeing cones than "fine print"

Powertrain
• 4.6-liter, 3-valve SOHC V-8; 315 horsepower
• Tremec TR-3650 5-speed manual transmission
• Signature Bullitt exhaust sound
• New open-element cold air induction system & hood blanket with AIS seal
• High performance calibration
• Dual knock strategy enabling the vehicle to run on either regular unleaded or premium (for improved performance)
• Crisper throttle response
• Revised cam timing at peak power
• Redline increased by 250 RPM to 6500 RPM
• 3.73:1 axle ratio

 

By my calculations, that means the same 64mph 2nd gear on 285/30-18 A6's as the 3.55 geared '07 cars at 6250rpm. Of course, the nature of the rev limiter might not be "soft", like the Shelby.

Have you, or anyone you know, run the 275/35-18 A6? (for all I know, that may be what you're using already)

To me, the redline means the redline.... like the Red Line on the tach.  Where are they talking about the rev-limiter? 

 Yeah, you could run 275's and that will get you more speed in 2nd than with 285's.  But still less than a 3.55 axle w/285's, and now you get to sit another .3" higher off the ground too.

I did run 275's.....  I was a bit quicker on 285's.  We'll see about next year................

The sales material flat out says 6500rpm red line (raised 250rpm), so I'm not sure what you mean when you say "the redline means the redline"? It seems pretty straightforward, regardless as to what is printed on the tach face in pre production photos.

I was bringing up the rev limiter, because it sounds like there are two types used on the Mustang and there's no way of knowing which type is on the Bullitt, yet.

In another post you stated that someone you knew had seen one of these, and the tach was marked 6500 for redline.  I was pointing out in the press pics that isn't the case. 

 The Redline in a GT is 6000, as it is in the Shelby.  The Rev-limiter (which is different) is 6250 in a GT, and presumably 6500 in a Shelby as it uses the FR1 calibration, which is what it was stated the Bullitt is going to use, and I'm sure it will as it has the same type of intake and why would Ford make a whole new cal. for a limited car when they hadn't for the Shelby. 

 You don't have to buy what I'm saying, but mark my words there will be no magical differences and the Bullitt will go slower in 2nd than a Shelby will on the same tires, and probably a touch off what a stock GT can run on the same tires given the gearing differences. 

 I might be wrong, maybe the Bullitt will be the new killer FS car.  I hope we find out.  But I'm looking at it and thinking all else being equal it won't be a killer.  Unless something amazing happens with the suspension (which we don't know until we run one) this is all conjecture.  Bottom line is the car is a Shelby, but taller with shorter gearing and unknown springs and bars.

Got 'ya.

I think your last sentence sums it up:  "Bottom line is the car is a Shelby, but taller with shorter gearing and unknown springs and bars"

Now, on to the 350hp GT for '09 rumor...

From what I remember when looking at the tunes side by side, the Shelby rev limiter was in the ~6350 range, about 100 rpm higher than the stock GT.

Well, if that's true....  And it's tangible information since I know Brian's seen a Shelby tune on a laptop, that's a plus in the Bullitt column since it won't be way off on speed (1 mph or so).  Then it's matter of if the limiter is has the soft first step like the Shelby, or just slams headlong into the thottle cut like the GT's.

Yep, that limiter thing is a question mark.

The other thing is what the spring package is really all about. If the rear is lowered only 6mm, it may not have the problem you talked about in the Shelby with lack of travel. But, if the front is higher and softer, that isn't neccessarily a good thing. I wonder how, now that the car is out in the public domain, we could get the actual specs on the Bullitt springs?
