fastphil666 Posted October 20, 2019 Share Posted October 20, 2019 Good afternoon folks, Whats the theoretical top speed of a mk4 tt auto with a02 diff? On a recent spirited drive with a friends r33 gtr on private land of course... i saw an indicated 165/170mph. I thought this was my speedo over reading but he was flat out in 5th! I passed him and kept going. Thoughts on top speed of a mk4 auto?? Link to comment Share on other sites More sharing options...

Frank Bullitt Posted October 20, 2019 Share Posted October 20, 2019 In theory isn't it a fraction over 200mph using an auto rear end and 17" wheels. I would imagine you would need some room to hit that though. Link to comment Share on other sites More sharing options...
jackso11 Posted October 20, 2019 Share Posted October 20, 2019 Is it 200? I had always thought it was around 165. Link to comment Share on other sites More sharing options...
Mo Reviews Posted October 20, 2019 Share Posted October 20, 2019 I managed around 200mph in my old Supra auto... well at least that's what the nav was showing. Link to comment Share on other sites More sharing options...

rider Posted October 21, 2019 Share Posted October 21, 2019 i recall reading that the top speed of a TT6 was 168mph but that can be affected by various factors like uphill, downhill, back wind, headwind, tyre circumference, engine limiter. My car is limited so I only managed 158mph on the speedometer before the limiter said no. Link to comment Share on other sites More sharing options...
AC93 Posted October 21, 2019 Share Posted October 21, 2019 stock rears are 255 40 17 Oh yeh, my bad! Got mixed up with the profile for stock TT front tyres.. Top speed would be 188 @ 6700rpm Link to comment Share on other sites More sharing options...
Frank Bullitt Posted October 21, 2019 Share Posted October 21, 2019 Up the rev limit to 7200 so it's the same as the VVT-i and you should get there. Link to comment Share on other sites More sharing options...
Noz Posted October 21, 2019 Share Posted October 21, 2019 I'm pretty sure I was on land. I didnt think it was particularly a challenging question. Link to comment Share on other sites More sharing options...

Noz Posted October 21, 2019 Share Posted October 21, 2019 Unfortunately, I found it embarrassing for lack of particularity. Oh how awkward. Let me correct that. Where did you do 200mph in your auto Supra where the sat navigation was indicating your current speed. Country. Road. Location. Area. Link to comment Share on other sites More sharing options...

Noz Posted October 21, 2019 Share Posted October 21, 2019 Most of your comments on this forum seem to offer no benefit to this forum to be honest. Just smart arse remarks.

Sukhy Posted October 21, 2019 Share Posted October 21, 2019 I remember it being something like 187MPH.. Link to comment Share on other sites More sharing options...
Mo Reviews Posted October 21, 2019 Share Posted October 21, 2019 (edited) Most of your comments on this forum seem to offer no benefit to this forum to be honest. Just smart arse remarks. People dont deserve that here. Many offer help and advice. Not to be talked down too by people like yourself. Attitude isnt welcome here. Most of your remarks carry a distinct tone of holier than thou sarcasm but who cares right? I am astonished at people who wonder why this forum has turned in to a ghost town... If someone asks a stupid question then gets offended when they receive a stupid answer. It all gets rather childish in the end and people start throwing strops. I am a straight talker, I certainly don't try and put icing on poop so you either like it, or you don't. Give me respect and the favour will be returned, the inverse is, of course, true.

fastphil666 Posted October 22, 2019 Author Share Posted October 22, 2019 Thanks drift bear for the links to the calculator. Thanks to everyone else for their imput. Its not an act that i really want to repeat, just that ots the fastest car ive driven/owned by these figures. She got there in relatively short stretch of road too. Cars bpu with a mines ecu so i think its got the 7200 limit? Personally top speed doesnt do a lot for me its the acceleration, just that day i kept accelerating!
