A couple performance questions

[cp5899]

Do you think the 350's will come with the same gt axles or something stronger?

Also, what are the chances the supercharger company's make a setup for the gt350 and gt350r?


I love my gt, but the idea of having a fpc is awesome. Only way I don't order is if ford drops the gt500 bomb and it is over the top.

These cars have half shafts and the GT350s are upgraded. I don't think a supercharger is necessary and most are not designed for high rpm unless they are centrifugal but I do think we will eventually see some on the after market. The GT 500 will eventually come back but in what form????

Half shaft were what I was referring to. The gt ones seem to be junk and hopefully the gt350 are a good bit stronger.

Junk? In what way? Drag racing and high RPM launches with a sticky tire? Yep, weak link for sure. DD and roadcourse racing? Just fine...unless you have crazy power.

Upgrading half shafts is not very difficult or expensive. I'm all in for a GT350 though.

Junk in the sense that previous years of Mustangs could handle a lot stickier tires and high RPM launches without problem and now the latest Mustang is much more fragile.

Many people were worried about this and now we see it happened. IRS is a compromise just like any other design decision.

I bought wider rear rims for my 2011 and sticky summer tires so I could accelerate better (on the street). I'm not sure whether it's a good idea on the 2015, and that's crummy IMO.

$1700 is the price I'm seeing online. Seems like a lot of money to me.

Do you have a source that the half shafts are upgraded?

+1

I don't think they will be hard to change, but $1600 is steap to do what the mustang has always been able to do. I love my car and its handling capabilities, but drag racing is why I came back to the mustang.

Nothing you do on the street with street tires is going to break the stock half-shafts.

Post #1 in the GT350 release thread:

TRANSMISSION & DRIVETRAIN:

Q: Tell us a little about the transmission.
A: It’s a Tremec 3160 transmission that’s been modified fairly significantly to cope with the demands of the flat plane crank engine.

Q: What about the fly wheel and the clutch?
A: It’s got a low inertial dual mass flywheel and two 15-mm dual disc clutch.

Q: Does it share the halfshafts with the GT?
A: No, they are upgraded.

Respectfully disagree 100%. Well, yes you are correct nothing I will do will break them because I am going to be careful with my new piece of equipment. However, if someone were to buy 10" or wider rims, install drag radials and do 5,000 rpm + launches I bet they would break on the street.

That's an extreme example but I'd like to know where the failure point will be. If I get a little wheel hop on sticky drag radials will they break? I bet in 6 months or so we will see some reports of this happening.

He said they wouldn't break on street tires. Your example is using drag radials which are not street tires so I'm not sure how you're disagreeing with him.

The point is that street tires aren't going to have enough grip even with 1000HP to break the half shafts, they'll spin first.

Thanks for the info on the half shafts. I had forgotten about that. All good news.


As for breaking the shafts on the street? I'm not sure, but I have had some tremendous wheel hop on the street that I let out because I was afraid of breaking them.

Drag radials are street tires. They are DOT approved.

For the 2011 I bought Pilot super sports for the rear. Those were pretty sticky but I was thinking about trying to find something even better for straight line this time around just to see what the various tires are like. Now I'm thinking I'd be better off just leaving it alone. Play it safe.
