morning Gents
Long time hvn't been here.
Hv strange situation with my Arosa..... placed in it G60 charger , port & polished head , all went well but when placed car on dyno and started fine tuning discovered that i can nog get more than 54 HP on wheels ?? when G40 has been placed in it managed to measure 139 Hp on wheels.
Presently boost presure is 1,2 Bar , so charger is ok. Head has been tested, no blowing on side, pipes checked, petrol pump changed ... fm technical side all is ok.
Do somebody know what could be the faliure ? it's strange thing that G60 can give 54 HP...
Is it possible that triger wheel is not in the right phase ? - how I should trim it ?
is it possible that valve springs are not working fine ?
Tks in advance for your comments
