I don't have a graph readily available on the turbos but for those considering this kit you most likely will have a ceiling in the 650-750rwhp range depending on all variables. This kit is for anyone wanting 600-700rwhp on a bone-stock or light bolt-on car since that is effectively the limit of the stock engine / drivetrain (Or slightly beyond
If you plan on a built engine to really run some boost or want to make more than 800rwhp that is where the GT-based kit shines. The large 1.02 A/R and 3" downpipes will flow enough for 1200+rwhp.
