Gt-p Gets Spanked

[Adam]

I remember reading in Motor that they're working on a auto test piece, whether the XR6T, XR8 etc are included in the test remains to be seen. One can only hope!

Plonky - agree with your point on engine torque. I think that the T could be as much as 100kg lighter than the GT. Can someone please confirm.

Note the following (per Ford and FPV respectively):

XR6T 450Nm from 2000rpm to 4500rpm (max power 240kw at 5250rpm)

GT 520Nm at 4500rpm (max power 290kw at 5500rpm)

I own a T and have never driven a GT (but would love to and will make this a priority). Admittedly, this will make my assessment of the T a bit biased.

The figures above highlight that the T has very strong low to mid range torque. The T especially has a massive kick from 2000rpm which makes it very well suited to an auto transmission.

I would also speculate that if the torque curves of the GT were overlayed on T, the T would have more low to mid rpm torque and that the power curve of the GT would continue upwards from 4500rpm or so whilst the T would be beginning to flatline.

Note that the GT does not produce max torque until 4500rpm. I would suspect that that the T may have more torque than the GT at around 3000rpm (and less weight than the GT). Hence the T would be able to run away from the GT. At this point I would speculate that the GT simply playing catchup.

At some speed above say 120km/h for arguments sake, I would expect the GT to pass the T due to the GT having a stronger top end (I.e. more top end torque).

If I had the bugs...I would go into a Ford dealership tommorrow and buy a GT....not saying I don't love the "T" but I love that V8 burble..its so sweet...well that's my 20 cents worth...I'm not really too bothered about quarter mile times or 0-100 times...lets face it both cars are quick enough..well for me anyway....(I'm probably showing my age)....a RED or Orange GT with stripes sounds so yummy...

Auto's should always be better over the 1/4 than manuals.

You are dreaming.

[Guest esky]

The GT has a good power to weight ratio but has significantly more torque (pulling or turning power)

.

It may have a higher maximum torque figure, but it's average isn't over the XR6T's.

I think we can come to the conclusion the GT is more about show than go.

Not that 'go' is the ultimate goal.

Come on Mr Walker, you don't seriously suggest that 2 equally configured transmissions, 1 manual and 1 auto, would not show the auto to be better?

If you look at standard street cars, then I agree that most manuals, with a good peddler, will outperform an auto, because the positive mechanical actions of a manual and clutch set up are usually more efficient than a comparable auto, but if you look at the top categories of motorsport, namely F1 and drag racing, the transmissions are either auto or hybrids.

That is because the laws of physics dictate that the human brain and leg can't operate as fast as a "computerised" version.

I have the auto so have a preference toward that transmission, that being said, the auto and manual aren't configured the same. I dont know the exact ratio's but the auto's 1st gear is a lower ratio than manuals, giving the manual better acceleration. So in a perfect world the manual would be faster. In the real world however the auto is easier to launch. I think if you had 2 equal cars with 2 similar skilled drivers the manual would get the best 1/4 mile time, but that the auto would beat the manual more often than it would lose.

These are my thoughts and not facts, so flame away if you feel the need. I'll just turn the aircon up. B)

Transmission gear ratios are as follows for the XR6T, couldn't get the GT's.

1st 2nd 3rd 4th 5th R

Auto 2.50 1.49 1.00 0.68 - 2.07

Man 2.95 1.94 1.34 1.00 0.73 2.76

Well that's just f#$kin great I spent 10 minutes spacing that out all nice and neat, and look what happened

Hope you can still follow it.

Also, the auto will be on full boost throught the gear changes, unless you can flat change a manual, the auto "should" be quicker.

The throttle body will be open 100% of the time in a auto, therefore keeping the turbo, and intake manifold fully boosted. In a manual, unless you flat change, the throttle body will be opening and shutting a little during gear changes, therefore slowing the turbo down, and boost levels wont be at 100% all the time.

All of this goes out the window with N/A cars..... cause there is no boost!

Hope this all makes sense!!
