The N54 is capable of 500-600 bhp but not really on stock turbos. Is this due to stock turbos just can't flow that much air? Is the workaround to increase the timing advance once limits of turbos is reached which then demands more octane or ethanol?
Is the N54 also limited by the compression ratio? Doesn't this affect how much timing advance you can get before getting a knock/pre-detonation? Do bigger turbos allow less timing advance and more air? When people talk about "aggressive" tunes are they talking about timing or boost or both?
