SupraP-Z Posted September 30, 2014 Share Posted September 30, 2014 Ok so having the W58 5 speed box is a bit of a set back in terms of turboing the supe, I have a few questions about driving on the motorway. As far as im aware, the turbo will kick in at anything between 3-4k revs depending on the set up...now if im cruising 80mph down the motorway in 5th gear, im at around 3k revs already, am I always going to be on boost at that point? I wont have any gears left to shift to. With the 6 speed you would shift to 6th and the revs would drop, allowing you to cruise off boost? How do you guys normally drive on the motorways?

mattdavies Posted September 30, 2014 Share Posted September 30, 2014 If you are just crusing then you will be off boost, But if you put your foot down the boost will build and you would be off Quote Link to comment Share on other sites More sharing options...
SupraP-Z Posted September 30, 2014 Author Share Posted September 30, 2014 Ah ok, but wouldn't the turbo be coming online at that point, so it would be spinning up ready to go? Quote Link to comment Share on other sites More sharing options...
mattdavies Posted September 30, 2014 Share Posted September 30, 2014 If the throttle is at a steady state then it will not be producing positive boost. It will spin up quicker then it would at lower Revs when you do accelerate but it would not be " spinning up" Quote Link to comment Share on other sites More sharing options...
Style Posted September 30, 2014 Share Posted September 30, 2014 The 6 speeds are closer ratios so 80 in 6th will see the same revs as a 5 speed at 80. So it makes no difference really. If my thinking is right, the turbo would in theory be spinning at cruising speeds but wont be positively boosting as mattdavies said. It's not like the car will accelerate by itself or anything.

SupraP-Z Posted October 1, 2014 Author Share Posted October 1, 2014 Brilliant, everything is starting to piece together. Still trying to get my head around how it would drive as a small single - thanks for the info guys Quote Link to comment Share on other sites More sharing options...
Rich.2211 Posted October 1, 2014 Share Posted October 1, 2014 Brilliant, everything is starting to piece together. Still trying to get my head around how it would drive as a small single - thanks for the info guys Mine literally drove exactly as it did when it was NA until you put your foot down and it's under load/building boost and then you take off You may lose a little bit of responsiveness but it's hardly noticeable and certainly doesn't affect the drive.
