Hom many manual GT & GTP-S are out there Vs the new Auto?
Some tell the auto is the best by far, even smokes em up with ease. Myself went for the manual thinking to get another 0.5kw of power and so wanting to get the most bang for my buck. Are the auto's better these days given the tip-tronics and can hold them in like a manual etc, i'm sure you al know. What about the power lost in the drive train? Is there any loss?
Whose driven both or compared and can solve add to the dilemna?
How many manual GT & GTP-S are out there Vs the new Auto?
Some tell the auto is the great, even smokes em up with ease. Myself went for the manual thinking to get another 0.05kw of power and so wanting to get the most bang for my buck. Are the auto's better these days given the tip-tronics and can hold them in like a manual etc, I'm sure someone knows. What about the power lost in the drive train? Is there any loss?

Having driven both under track conditions I'd have to say that under those conditions the manual would be my first choice if only because there is a marginally higher degree of control, a better spread of ratios (for Sandown anyway) and the auto has a habit of not holding downshifts when it gets a bit overheated.
In terms of straight line performance there are only fractions between them in 0-100 and standing 400 m times with most drivers achieving quicker times from the auto due to the difficulty in launching the manual cleanly.
Build numbers to date favour the auto in a 63:37 split but this is probably impacted by the higher number of GT-p sales.
There are greater driveline losses from the torque convertor although they are nowhere near what they traditionally were. Greater impact is likely to come from the overall difference in gear ratios anyway.
I'll add my comments based on my experiences with an auto XR8. I believe the autos are quicker down the strip than the manuals in both the XR8's and the GT's, although it would be very minimal differences in the GT as both auto's and manuals run the same diff ratio whereas the XR8 manual has a taller diff ratio. I have run a 14.2 in my stock XR8 at Calder which is quicker than any times I have seen for manual XR8's. Manuals aren't geared as well as they should be although the first gear in the autos is too tall, and they are very hard to get off the line without wheelspin, which I think is their biggest problem. An auto will leave the line against the stall at 2500rpm and just chirp the tyres where if you use that many revs in a manual you will most likely wheelspin for a fair distance. Consistancy is also better in an auto where a manual will be all over the place in times as it will either wheelspin or bog down, as finding the sweetspot seems to be very hard. Look how hard Motor had to try to get a 13.98 out of a GT. Just my thoughts, although I'm sure a lot of you will disagree.
Well it all depend's on how you like and want to drive,if you want to race go manual,if you want to cruise go auto,there is a difference in the power loss through the drivetrain it's about 25-30% for a manual and 30-35% for an auto,the auto in stock trim will bogg down of the line compared to the manual,but like I said it all come's down to personal prefrence and just what you want from your ride and how you want to drive it.

I just love my auto, it's had the herrods teatment and will have the induction done in about 2 weeks the wheel spin is amazing and its only going to get better.It lays rubber with ease and after seeing Cam's GTP do 13.7 at Calder with ordinary tyres and to much wheel spin of the launch with a better technic that time could come down to the low 13s easy.
I find the auto's in the GT's bullet prove in manual mode they are just great to play with and will match it with most.
Cheers John
