RB-GTE Posted June 19, 2012 Share Posted June 19, 2012 I've had a fewTT 6-speed Supra's.. the most for mods was just intake, intercooler, and exhaust. I've never done the full decat and experienced anything past 0.7bar. I'm just wondering once you do all the BPU mods or even go into TTC mode, and pushing about 100bhp or so over stock... does it pull much harder vs stock and is it noticeable. I find the stock TT 6-speed very quick but not exactly that fast. Well.. I hope to be blown away once I do all my BPU mods Quote Link to comment Share on other sites More sharing options...

mattdavies Posted June 19, 2012 Share Posted June 19, 2012 I found it in my auto as stock......pretty linear acceleration and then the second turbo kicks in and you accelerate a bit quicker. BPU....put your foot down lots more turbo whistle accelerate a bit quicker then stock, second turbo kicks in and you bloody know about it and you smile Since BPU I make sure i am holding the wheel with two hands.

tony tt Posted June 19, 2012 Share Posted June 19, 2012 It's very noticable mate it pulls like a train massive difference imo over stock. It's a completely different car when full bpu. Quote Link to comment Share on other sites More sharing options...

Littler Posted June 19, 2012 Share Posted June 19, 2012 What makes a full on Bpu car.... see some folk with very different mods to others and to me infact. Based on what I remember you have the BPU mods but you just need to set the boost controller to set it 1.2 bar as at the moment you are probably at around 1 bar, once you up the boost you'll have a big smile on your face Quote Link to comment Share on other sites More sharing options...

Abz Posted June 19, 2012 Share Posted June 19, 2012 kickdown in a full bpu auto is savage. Yep, the BPU is felt much more in the auto's than the 6 speeds! Quote Link to comment Share on other sites More sharing options...
mattdavies Posted June 19, 2012 Share Posted June 19, 2012 Why do you feel it more in the auto then the 6 speeds ? Is it down to the number of gears and the speed at which you travel through the gear ? Quote Link to comment Share on other sites More sharing options...

I'm not sure which to go with now. Quote Link to comment Share on other sites More sharing options...

It is more the rapid change in the gears which gives that effect, the speed is more or less the same. Quote Link to comment Share on other sites More sharing options...
Guigsy Posted June 19, 2012 Share Posted June 19, 2012 My bpu auto has more of a kick in the pants than my small single. Although the single is faster in the long run. Quote Link to comment Share on other sites More sharing options...
Littler Posted June 19, 2012 Share Posted June 19, 2012 I haven't driven a manual BPU but have driven my stock auto TT and another members auto BPU and there is a hell of a kick with the 2nd turbo, particularly in 2nd gear! Quote Link to comment Share on other sites More sharing options...
thedirtycat Posted June 20, 2012 Share Posted June 20, 2012 Based on what I remember you have the BPU mods but you just need to set the boost controller to set it 1.2 bar as at the moment you are probably at around 1 bar, once you up the boost you'll have a big smile on your face Mine is running 0.8 bar of boost I think unless I had a boost leak when I first checked it. Even though I'm not running 1.2 bar of boost is seems so fast. Can feel the second turbo kicking in but the power still feels smooth I think. I was asking someone recently how much difference it would make if I got a boost controller and put the boost up to 1.2 bar. Need to sort out boost leak first though as its only reading just over 0.7 bar now Quote Link to comment Share on other sites More sharing options...
AJI Posted June 20, 2012 Share Posted June 20, 2012 Why do you feel it more in the auto then the 6 speeds ? Is it down to the number of gears and the speed at which you travel through the gear ? Probably because in 6-speeds you are in control and know when the boost is going to happen Quote Link to comment Share on other sites More sharing options...
mattdavies Posted June 20, 2012 Share Posted June 20, 2012 I know when the boost is gonna happen on my auto, at 4K rpm the second turbo kicks in, this is when both hands are on the wheel and I prepare for potential traction issues Quote Link to comment Share on other sites More sharing options...
