B3any Posted December 8, 2002 Share Posted December 8, 2002 Hey fella's with an Auto Supra if you were gunning for a 1/4 mile time or a 0-60 run is it quicker to shift manually or just leave it in Drive?? I feel its quicker by shifting manual but this could just be my imagination. Quote Link to comment Share on other sites More sharing options...

I would think! R Quote Link to comment Share on other sites More sharing options...
Barry Posted December 9, 2002 Share Posted December 9, 2002 If you use manual mode you will be able to shift before red line. You really want to try and keep the revs around the point where the engine is making peak torque. So shift just above that point rather than rev the nuts off it.! Has anyone with an auto noticed that when you are in manu mode and giving it a bit of large right foot, that when you are in 3rd (D) and want to go to OD (4th), when you switch off MANU at anything over 4k rpm soon as you do switch it off your revs rise another 2-300rpm.!!?!

kubus1 Posted December 9, 2002 Share Posted December 9, 2002 Yeah, I ve noticed that. Its strange as you would think that if you are in 3rd and then go to OD you switch to 4th. When you turn off MANU your revs change again. We have a 4 spd Auto, so why does it happen? Quote Link to comment Share on other sites More sharing options...

Barry Posted December 9, 2002 Share Posted December 9, 2002 No no no no no...! Your in MANU mode, foot to the floor in 3rd. Overdrive is currently off. Revs are creaping (or rather shooting past 4500-5000rpm). Press the MANU switch to turn it off so I am able to select OD. But, as I switch off MANU, the revs go up another 300 odd rpm. Thats before I engage OD, which obviously sticks it in 4th bringing the revs down again.! Most odd.! Quote Link to comment Share on other sites More sharing options...
Matt Harwood Posted December 9, 2002 Share Posted December 9, 2002 Never noticed before but I'll try it tomorrow and report back Quote Link to comment Share on other sites More sharing options...

Could it be some of the clutches unlocking, i.e. your revs increase but your actual road speed won't as your clutches are not locked together. I know that using the manual button shifts the lock up points of the box, but unfortunately my knowledge of auto boxes is very limited.

B3any Posted December 10, 2002 Author Share Posted December 10, 2002 Looks like i've started something here, however no one has said whether its quicker to leave it in drive or shift manually??? Quote Link to comment Share on other sites More sharing options...
Justin Posted December 10, 2002 Share Posted December 10, 2002 I would say that in drive there is less room for error, ie changing gear at the wrong time. But I haven't dragged mine in Manu coz I am a man and apparently only women can perfom such multi task operations like flipping thru manu gears or washing up and ironing at the same time. Best person to ask to test would be Monkey Mark as he lives very close to the Elvington strip with timing gear I believe. Quote Link to comment Share on other sites More sharing options...
