With a mile long wait list reported by GM as up to a full year for some models of the C7 Stingray, the demand for these vehicles far outweighs their supply. When Chevy designed the C7, their intentions were to evolve the C6 into a vehicle that had performance capabilities that far exceeded the cost of the car. For those who are fortunate enough to take delivery of a C7 this year, the question becomes whether to mod the vehicle or not. While some owners are going to cherish their 455 hp C7’s in the picturesque stock form, what if you are someone that wants to get the most performance out of your vehicle? What direction do you turn if you want to maximize your power gains for your investment? Direct Injection One of the biggest differences between the 6.2L LT1 featured in the C7 and prior generation LS-series motors is that the new generation of Chevy small block motors feature direct injection as opposed to port injection.
When we asked Ryne what impact this has on the performance of the kit, he responded: “A port injection fires the fuel into the port, and you are firing into an area where it’s going to hit the port walls, it can sit on the valve and then it will sometimes wait for the valve to open and then draw in the fuel. With direct injection, it comes right out of the TDC on compression and then fires it so the fueling it gets is exact.” “If you run it too rich, you will run the fuel into the exhaust cycle, it will misfire, and will soot it up.

So you have to be careful not to run it too rich or it could get the rich knocks. Direct injection is just more exact. Everyone worries about DI being too lean but in actuality there is not much difference to a port injected car, it’s just more exact. As for timing, the timing is about the same as a similarly boosted LS3. On the same fuel at peak boost, an LS3 car with the same boost would be right around 11.3:1 air.fuel ratio with 13 degrees of timing as opposed to 12.4:1 air/fuel ratio and 14 degrees timing for the LT1.

For many car enthusiasts, forced induction has and will be the go-to when it comes to getting the most amount of power in relation to the amount of money invested in their project.
