my pulley is still standard, the computer controls a 'wastegate' type valve that bleeds off boost from factory. injectors standard as well, only supporting mods I did was tyres and coilovers lol
If I wanted more boost from where I am at the moment would need a new pulley, but along with more boost would become more heat, needing intercooler as well, and at that power level need injectors as well! This is why I'm happy with 'only' 370rwkw
not really, the ford heads meant to flow a lot better I think, thats why they make awesome power from just 5.0l (something along those lines) the design of the LS engines pretty old school in comparison - michael the bloke with supercharged XR8 would know more about the differences
