From 601 WHP bone stock to 936 WHP and a 9.38 @ 151.2 MPH quarter mile… so far 👀
We’ve shared each stage of our 2022 CT5-V Blackwing testing individually, but now that the combination has progressed this far, we wanted to look back at what the entire process actually taught us.
Bone Stock | 601 WHP / 629 WTQ
Stock Blower + AuxJection | 699 WHP / 736 WTQ
Kong X-Port | 784 WHP / 758 WTQ
Whipple 3.0 | 858 WHP / 830 WTQ
Current Whipple Combination | 936 WHP / 939 WTQ
Quarter Mile | 9.38 @ 151.2 MPH
One of the biggest takeaways from this entire progression is that AuxJection is not limited to lower horsepower ethanol builds. With the proper low side fuel system supporting it, the system is capable of supporting combinations approaching and exceeding 1,000 WHP.
We also learned a lot about where each supercharger combination makes sense.
The factory LT4 supercharger works extremely well on a stock or lightly modified Blackwing, but like anything, it eventually reaches the limits of what it was designed to do.
The Kong X-Port was a huge jump in performance while still retaining the factory supercharger assembly. If your goals are around the 850 WHP range, our testing showed just how capable a ported stock blower can be.
We see plenty of Blackwing owners jump immediately to a larger supercharger just to make around 800 WHP. You do not necessarily need a $9,000 supercharger system to get there.
There does come a point where a larger supercharger becomes beneficial, especially as power goals increase and cooling becomes more important.
The Whipple surprised us most in that area.
We intentionally retained the factory cooling system throughout testing. During a half mile run at 18 psi, charge temperature started at approximately 110°F and finished at 156°F.
The Blackwing fuel system surprised us too.
Going into development, we expected the Global B cars to run into low side fuel limitations similarly to the previous generation. Once we worked through the limitations in the factory fuel pump control strategy, we found considerably more capability in the stock system than we initially expected.
That testing also helped shape the Global B AuxJection strategy itself.
Unlike our previous E92 applications, the E99 Global B platform comes equipped with factory widebands. A significant part of development was integrating AuxJection with that factory strategy, refining our wideband control logic, and correctly handling control after fuel cut events.
So when we look back at 601 → 699 → 784 → 858 → 936 WHP, the important part is not just the number at the end.
Every step taught us something about the platform, the factory fuel system, the supercharger combinations, and how AuxJection needed to work with all of it.
This is why we test AuxJection through the entire progression instead of validating it on one combination and calling it done.
