LS1 C4B Supercharged.
I live in the UK and drive a Holden that I supercharged.I get detonation at 5000rpm + and feel it is lack of fuel.LS1 edit tells me that a/f ratio at 12.2 with occasional knock at max 3# Injectors fitted are Grey 0280155931 C927.
I cannot get anyone in the uk to advise me of the size of these injectors.Can anyone help and also what size would be recommended with a present dyno of 470bhp.
Thanks
