I have a bf mk II an was wondering if I'm aiming for about 300rwkw am I going to need valve springs replaced or just injectors. I know earlier ba's have the weaker valve springs but not sure if the bf can do with 300 rwkw.

I'm not planning on doing mine and am aiming for low 300's.

Posted 04/07/10 01:10 PM Share Posted 04/07/10 01:10 PM plenty of 06/06+ motors running stock valve springs over 400rwkw. Im on 350+ with standard v/springs in my 07 motor no problems.

But if you guys are running with stock springs then I don't see the problem.

You may not need them but your better of having them then not.

Tewantin to Cooroy rd yesterday with a full car ( luggage and passengers)flat 4th going into the cnr going up the hill flat changed 5th and started to get some valve float .Better to do them IMO. First sign of any issues for me, full car , full load , full throttle and a steep hill. Now where to get em done as I am not driving a 2000k round trip to CV ?
