Is that when you derestrict it then restrict it again?

Or is it when it's undies are too tight?

 

Unrestricted?

Derestricted?

Underestricted?

Deunrestricted?

 

:D

I have been in work since 12 in the afternoon. I am still here and will be for an hour or so. You you can understand how tired I am.

Bl**dy hell! Are you sure?! Has anyone actually done this, or is it based on gear ratios and theoretical bhp? Maybe a trip to Bruntingthorpe is in order.

he he im glad to report i managed a rock solid 164 mph (true speed logged) yesterday in France :D:D, car was still pulling like a steam train :D

Well I've seen a true speedo reading of 176 and it was still going.

It wasn't mine by the way ;)

With standard tyres -245/45ZR16 on 8.5J X 16 rims, the manual twin turbo (final drive ratio 3.69:1) the turbo achieves the following speeds:

Gear MPH RPM

1st 43 7200

2nd 72 7200

3rd 107 7200

4th 139 7200

5th 155 6000 with speed limiter

5th 165 6400 without speed limiter

5th 186 7200 intermittent theoretical, rev limited

 

The automatic ratios are: 1st 2.78, 2nd 1.54, 3rd 1.00, 4th 0.69, so results for the turbo are :-

(Maximum, as actual speeds will depend on torque converter slip):

Gear MPH RPM

1st 48 7200 Held in first

2nd 87 7200 Held in second

3rd 139 7200 Held in 3rd, overdrive off

4th 155 5500 with speed limiter

4th 178 6400 without speed limiter, not attainable by stock TT

4th 201 7200 intermittent theoretical, rev limited

As a lover of speed I am now so glad I agreed to him buying this car! Makes my MX5 seem like a little baby!

 

All I got to do now is persuade him to let me drive it;)

 

Dream on eh!

Seriously - would it though :confused: ? There would be quite a cool breeze at that speed...

LMAO.

 

Forget the 180mph, you hold any gear at 7,200 rpm for a length of time and you got trouble IMO !!!.

Nah - just turn your ignition off when you hit 180mph, you'd be fine ;) :D
