Homer Posted July 8, 2010 Share Posted July 8, 2010 190mph i woul be really impressed if my bpu could get up to that speed gps The 6spd is noticably quicker at the top end than the auto's. I'd be really surpised if any bpu auto got too much past 180mph, the 6spd will do a bit more, but not a lot! Top I ever got in a TT auto (UK spec) was 178 on the gps, it didn't feel like it had any more in it. homers post scared me means there is 50ish mph to come out of my engine and i allready had kittens That's the theoretical top speed if the engine has the power to do it (and the NA doesn't), so you'd struggle to get 150 in either the auto or 5spd Quote Link to comment Share on other sites More sharing options...
James Posted July 8, 2010 Share Posted July 8, 2010 I wonder what the most I could get out of my (pre-facelift) NA-TT 5spd would be? It's an SZ so no LSD. Seen 160 on the speedo (not GPS) on my test track. Quote Link to comment Share on other sites More sharing options...

Seen 160 on the speedo (not GPS) on my test track. 158.3mph mate. The engine makes no difference in theoretical top speed. If it's BPU and you have enough road I reackon you'd get to the limiter in 5th given the gear and final drive on the NA drivetrain. 160 on the speedo will be somewhere between 140-150mph actual mph.

paulrenn Posted July 8, 2010 Share Posted July 8, 2010 (edited) Suprised if 180 is all an upgraded Supra would achieve. I got 260 km/h (161 mph) out of my STOCK TT6, even with stock exhaust, and 4 spare wheels/tyres in the car adding weight... There was even another 1000 RPM to go before redline, but ran into a rainstorm and had to back off First pic in the link in my sig shows the dial in KMs. And this *was* in Germany Still, I suppose you get to 180 a lot faster than a stock car would Edited July 8, 2010 by paulrenn (see edit history) Quote Link to comment Share on other sites More sharing options...

Scott Posted July 8, 2010 Share Posted July 8, 2010 (edited) You will do 180GPS with not too much trouble. A full on healthy 430hp SRR BPU will manage around 190, it won't be impressive though. I have a facelift with a V160. Edit: Am I right in saying that the figures above won't be entirely accurate due to the 6800 limit? 7200 is the stock for a TT is it not? I have 8k on tap but I don't think I would be trying a top speed run with it, not without head work anyway.

bradleyh_15 Posted July 8, 2010 Share Posted July 8, 2010 where on the vin plate does it say transmission? Quote Link to comment Share on other sites More sharing options...
Scott Posted July 8, 2010 Share Posted July 8, 2010 Easy to tell if you have a pre-facelift bud. It's a 160 you will have. The changeover to the V161s happened with the VVTi engines IIRC. There may have been a small interim period though. Quote Link to comment Share on other sites More sharing options...
Nic Posted July 8, 2010 Share Posted July 8, 2010 where on the vin plate does it say transmission? That'll be where it says 'Trans/Axle', the first is the gearbox code, the second is the diff code. Quote Link to comment Share on other sites More sharing options...

I have 8k on tap but I don't think I would be trying a top speed run with it, not without head work anyway. 6800rpm for the non-VVTi NA and TT. The tach is VERY inaccurate if you are going by that alone. My old one used to read 7600rpm or so when the ECU showed it was only 6800rpm.

bradleyh_15 Posted July 8, 2010 Share Posted July 8, 2010 thanks guys never actually looked for transmission before so didn't notice it on there! that will teach me to open my eyes! Quote Link to comment Share on other sites More sharing options...

My old one used to read 7600rpm or so when the ECU showed it was only 6800rpm. Ahh, I didn't know that. I had often read 7200rpm quoted as the stock TT rev limit. Makes me worry about the Mines ECU opting for 8k. I don't mind a bit of a jump in revs but 1.2k without any other mods is a bit beyond my comfort zone.

jim Posted July 8, 2010 Share Posted July 8, 2010 They will do more than that, but need a *serious* amount of road to do it, literally miles of WOT once past 170! For info (and assuming stock size rear wheel diameter and stock rev limit), the absolute maximums (I.e. without power limitations) are: NA auto: 175.8mph NA 5spd: 158.3mph NA 6spd: 164.2mph TT auto (jspec & UK): 190.5mph TT 6spd (UK): 203.7mph TT 6spd (pre-facelift): 195.4mph TT 6spd (facelift): 189.1mph Maybe a stupid question, but why is the auto capable of highest maximum speed in an NA, but not in a TT?

Homer Posted July 8, 2010 Share Posted July 8, 2010 Maybe a stupid question, but why is the auto capable of highest maximum speed in an NA, but not in a TT? It's not capable of it, the figures are quoting theoretical top speed if the engine has the power to make it. Essentially it's about drive ratio (rpm of the engine vs output speed of the driveshafts). The gearbox and diff are the key factors when working out whats possible, engine power ignored of course. Lets say for example, someone has a TT engine, but 5spd gearbox and diff. The final drive ratio between the NA and TT drivetrain in this situation is the same so the maximum speed it can do doesn't change because the maximum rpm from the engine is the same as the NA (6800rpm) Quote Link to comment Share on other sites More sharing options...

The-Plethora Posted July 9, 2010 Share Posted July 9, 2010 Is there anyplace the club could arrange a 'runway day' or something? something longer than a drag strip, I wouldnt want to do these speeds on a normal road but curious as to what it could do, could be a fun day.

The-Plethora Posted July 9, 2010 Share Posted July 9, 2010 We should see about getting something sorted but wouldn't know where to begin. I suppose you would have 'elf 'n'safety' buzzing about though and need helmets and such. Quote Link to comment Share on other sites More sharing options...

Scott Posted July 9, 2010 Share Posted July 9, 2010 Will take more than 2 miles to hit 190 in a bpu. Look closer to 10 lol. Most of the single guys would manage it though Quote Link to comment Share on other sites More sharing options...
