Vantage Turbo: V8 Camshaft timing
Building the turbo Aston Martin V8 engine: Some reverse engineering. Previously we found out the Aston Martin V8 engine ‘breaths’ pretty well even in the high RPM. We determined this by dynoing the car. The torque was constant up until the rev limit. All aspects in an engine determine the general performance of the engine, but there is one main item in the whole engine that has the most influence on the characteristics of the engine and that is the valve opening and closing timing.
Vantage Turbo: Approach – Build a spare engine
Here’s the next chapter about our Vantage Turbo project. Today, I’ll tell you about the approach we will be taking with the engine itself. The power level we are aiming for requires the engine to be rebuilt with parts that can withstand more mechanical strength than in stock condition. OEM manufacturers make their engines not only for horsepower, but also for durability, sustainability, fuel economy (yes even on cars like Aston Martin), weight and most of all: production costs.
Vantage Turbo – project goals : 800hp!
We started this project with a horsepower goal of 800HP. This figure is pretty arbitrary. The Vantage with 4.3 engine has 380 HP from factory (400hp with the Aston power upgrade). Buying a Vantage V12 would get you say another 150 HP. We would like to have a much bigger step on top of the V12 power, and the next power level would be something like doubled the V8 horsepower: 800HP.
