The Aurora 4000 is a step up from stock, built around a 63 mm inducer and a billet compressor wheel. ATS rates it to about 600 hp with fuel and tuning to match, at boost levels past 40 psi.
ATS reports a 150-200 degree EGT drop and a ported compressor housing that cuts down on turbo bark.
Owners making more power who still tow and want strong spool and lower EGTs.
