Most hp on return less system

This is a BP customer with a 6266 T4 .81 a/r tangential (non twin scroll) turbo on a VQ35DE engine. This was a simple 9.8:1 CR short block build. Nothing else was done to the engine...just the short block build. Stock cams, stock intake...not even a plenum spacer:



Vince said that the tune was conservative.

With the VQ37VHR, you can expect even better numbers due to the increased efficiency of the twin scroll. 650whp on a DJ should not be an issue with the Stage I (6266) version of this kit, and 93 pump gas..... provided that the fuel support is there (pump/injectors/supply to fuel rails).

I have one customer that made almost 700whp (DJ) with a twin scroll 6766 T4 1.32 a/r turbo kit on a VQ35DE, also pump gas and a short block build. (sorry don't have the dyno for that).
