GeordieSteve Posted April 30, 2007 Share Posted April 30, 2007 Does anyone know roughly what RPM you'd be running at 70mph with this box http://www.horsepowerfreaks.com/price/Toyota/Supra_93-98/BM/Transmissions/Transmissions/part/TH400_Race I'm looking for a built box (th400 ideal) but don't want crazy rpm while cruising down the motorway Link to comment Share on other sites More sharing options...
carl0s Posted April 30, 2007 Share Posted April 30, 2007 According to this, it'll be exactly the same as fifth gear in a 6spd manual, fourth gear in a 5spd manual, or third gear in an A340E. Link to comment Share on other sites More sharing options...
GeordieSteve Posted April 30, 2007 Author Share Posted April 30, 2007 oooo thanks Carlos. Looks like just the ticket Link to comment Share on other sites More sharing options...
Terminator Posted April 30, 2007 Share Posted April 30, 2007 The TH400 will match your third gear of the standard auto box. You are looking at 70 @3500Rpm with the auto diff. Factor a 6 speed diff into the equation and 70 is achieved at just a little over 3000RPM Link to comment Share on other sites More sharing options...
GeordieSteve Posted April 30, 2007 Author Share Posted April 30, 2007 The full kit comes in at around £1500 (before delivery) with the current £/$. Seems a smart purchase Link to comment Share on other sites More sharing options...
GeordieSteve Posted April 30, 2007 Author Share Posted April 30, 2007 hmmm the full kit is for the 4L60E. What additional kit would I need with the BM TH400? Link to comment Share on other sites More sharing options...
