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).

Are you talking about Binder's car from my 350 forum ?

No, binder made 651whp but his twin disc clutch went down the hill after that....just couldn't hold the power. The 651whp was at about 6,000rpm...so he still had a lot more left in there if it wasn't for the clutch slipping.

Found the graph of Binders car, and his twin disc clutch letting go. This is also the older 6765 turbo, the 6766's are a nice improvement in every aspect:



Don is the one that made almost (if not exactly) 700whp on a DJ. This was on a dyno shoot-out event...hence no graph.
