NathWraith Posted July 10, 2012 Share Posted July 10, 2012 Hey guys, Is there anyone on here who uses a TT Auto supra on track? I know manual is the preffered choice but not all of us Supra owners can be belssed with a 6 speed, so my question is do any of the auto guys take their supra's on track and how do you find it? I would imagine due to the longer ratios, 2nd and 3rd with manu mode on and overdrive disabled would be the way to go. Look forward to hearing from you guys.

Chris Wilson Posted July 10, 2012 Share Posted July 10, 2012 I ran my J-Spec TT auto on umpteen track days and it was good fun. I also ran J-Spec brakes and with careful choice of pads and fluid got them to survive on most circuits (Donington GP circuit was their undoing, but it's rarely used for track days BECAUSE it's so hard on brakes). Run the box in manual mode, you don't want it doing its thing mid corner in the wet!! I did not disable O/D, as far as I can recall. It'll be fine Quote Link to comment Share on other sites More sharing options...
mellonman Posted July 11, 2012 Share Posted July 11, 2012 i run mine round brands hatch a few times, i run with O/D off and just left it in D i was very suprised how well it goes it would be better in manual mode but i was to lazy for that and your only going to use 2nd and 3rd , give it a bash its great but your brakes do get a pounding as there is no real engine braking unless in manual mode Quote Link to comment Share on other sites More sharing options...

It'll be fine There'd be no point, in MANU mode you can't get into OD anyway. (Excluding the documented exceptions) Quote Link to comment Share on other sites More sharing options...
The-Plethora Posted July 11, 2012 Share Posted July 11, 2012 I have been on track a couple of times and the car is absolutely flying! I wouldn't worry about having an auto in the slightest, what I would be concerned about is as the others say getting a decent set of pads and making sure you have decent cooling and let the car idle for a decent time when you finish. I was suprised how much the stock pads faded during the laps. Quote Link to comment Share on other sites More sharing options...
TubbyTwo Posted July 11, 2012 Share Posted July 11, 2012 Thats good then, looking forward to taking mine on track. Guess a autobox & oil cooler is a must? Quote Link to comment Share on other sites More sharing options...
Wez Posted July 11, 2012 Share Posted July 11, 2012 I used my NA auto on track at Brands and Silverstone a few times, always had great fun Decent pads, fluid and a health check and you should be good to go Quote Link to comment Share on other sites More sharing options...
Dnk Posted July 11, 2012 Share Posted July 11, 2012 No problems here other than the odd bit of pilot error I'd get your suspension geometry checked as well as the health checks mentioned above. New brake fluid is a must unless you know its been changed recently. I always did a cooling down lap after being on it but just remember to keep out the way of everyone else Quote Link to comment Share on other sites More sharing options...
Gaz6002 Posted July 11, 2012 Share Posted July 11, 2012 let the car idle for a decent time when you finish. I was suprised how much the stock pads faded during the laps. Careful not to put the handbrake on though Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 11, 2012 Share Posted July 11, 2012 (edited) PLEASE do not try running full auto in the wet, it is asking for a spin as it decides to change up or down when you are on the limit in corners. You wouldn't change gear mid corner manually, or if you did have to, you would be damned sure to get the clutch release Miss daisy smooth. The auto will cause sudden power and weight transfer and unless you are good, fast and dead accurate with opposite lock, you'll be wondering what happened This is why experienced bike riders rarely spin road cars, they know all about sudden torque reversals, mid corner braking and mid corner gear changes, and probably have at best, soiled leathers to recall it by, and at worst, a few scars! It's all fairly simple physics, and easily worked around if you think about what's happening.

NathWraith Posted July 11, 2012 Author Share Posted July 11, 2012 Thanks for the replies guys. Yeah I know about the harshness on brakes and the cooling off side of things. Just need to get some good fluid in really. I had motul rbf 600 in my 350z and got HKS braided lines done also. May be worth doing the same to the supra then.

Rajinder Posted July 11, 2012 Share Posted July 11, 2012 As said above to drive an auto on the track you need very good brakes and I mean good brakes, as you do not have the luxury of engine braking as with a manual. Quote Link to comment Share on other sites More sharing options...

TubbyTwo Posted July 11, 2012 Share Posted July 11, 2012 for occasional track days would an oil cooler be worth it for the engine oil and auto box? Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted July 11, 2012 Share Posted July 11, 2012 for occasional track days would an oil cooler be worth it for the engine oil and auto box? for hard driving the autobox will apriciate a cooler yes. if its your daily too a stated engine oil cooler would be good, but if your not doing extended runs then its not allway essential, id say get an oil temp guage first and see how it does Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 11, 2012 Share Posted July 11, 2012 An auto certainly does have engine braking, where did that idea come from? Quote Link to comment Share on other sites More sharing options...
mellonman Posted July 12, 2012 Share Posted July 12, 2012 An auto certainly does have engine braking, where did that idea come from? yes but only in manual mode or turning O/D off while in 4th but most tracks this would be not much help as 4th gear is selected around 130mph Quote Link to comment Share on other sites More sharing options...
mawby Posted July 12, 2012 Share Posted July 12, 2012 You don't need to use MANU to force the gearbox down a gear - just move the lever. Quote Link to comment Share on other sites More sharing options...

mawby Posted July 12, 2012 Share Posted July 12, 2012 And in case anyone wasn't aware, the lever can be moved between N, D and 2 without pressing the button. This allows 'enthusiastic' handling of the lever without worrying about accidentally dropping into 1st or reverse by mistake. Quote Link to comment Share on other sites More sharing options...

qwarrior Posted July 12, 2012 Share Posted July 12, 2012 I find moving the auto gear selector is not as responsive when MANU is off as it is with MANU on. The last few track days I have driven MANU on, O/D off, Slip Control Off in the dry. I have Black diamond slotted and grooved discs with EBS Yellow Stuff pads. I can normally get in about 10-15 laps of a reasonable length circuit before having to come off to cool them. Back tyres normally take a hammering with Track Control off and a set of Yellow stuff normally lasts me two track days on the front and 3 or 4 on the back. Just the facts, different driving styles will yield different results. (But, as above don't use full auto in the wet, that would be an expensive and smelly mistake) Quote Link to comment Share on other sites More sharing options...
