        when pushing it i`de say no higher than 5600 RPM`s until you get a feel for it , then once you get a fell for it you`ll know where the limiter is without hitting it . hope that made sense .

        ALLWAYS make sure the car is FULLY warmed up 1st before giving it a bit and same for cooling down . lay off the gas for the last few miles of the trip before stopping .

        look after the car and it`ll look after you

          personally for commuting i'll change at just under 3k, but for clean economy, weekends get 5500 but never limiter to look after her, and as agreed always cooling and warming up until coolant etc at average nums

            There's no point in hitting the redline, as the Torque and performance will have already dropped right out. Having seen the rolling road graphs from Bluefinned vectra VXR's it's clear the shift point is actually somewhere between 5000 and 5500 rpm.

            It was the same in the Impreza STI I had - rdline was 9000rpm but the shift light in mine was set to 6200 rpm because anything after that and the Torque was just tailing off too quickly.

              as above, change gear according to how the car feels.

              whenever i drive, i usually short shift to keep economy

                  Its good to feel the torque pulling the car so around 5600-5800RPM is good for that. But outright pace .... around 200-400RPM away from the limiter

                      bump.
                      What about one running a hybrid?
                      5500ish...or closer to the redline?

                        depends how deep you pocket is

                        What i normally do when i'm low in funds is : change before 2k.

                        when funds becomes available, then obviously it is fun times

                          i was reading sum maps the other day and i think stage 2 the power starts 2 drop about 6 thou RPM so my guessing is, prob be good 2 change then (if stage2 of course)

                            When a feel tired and don't want speed, i'm going in vegetable style - shifting in 3500rpm, thats keeping quiet atmosphere in car and comfortable driving.
                            When am going to burn some tyre, push pedal to the metal or just some fast driving, shifting are around 5500rpm.
                            But remember to hold tight your steering wheel when shifting

                            My record was 8.5litres/100km in normal driving, and 18 in super-crazy

                              Theres no point in hitting the limiter in a turbo car as thats the point of a turbo. A NA car needs to have it's **** reved off as they dont produce much power/torque until late on in the rev range. It's the same as you dont see many turbo cars running throttle bodies and very few running wild cams as its just not nescessary in a turbo car as its already forcing air in.
                              Saying that my mate has a 650bhp Celica GT4 and that revs to 10,000rpm and sounds amazing lol
