David Stuart, the Virgin Australia Supercars Championship sporting and technical director, said building and testing the engine was a crucial learning exercise for developing the Gen2 engine specifications.
“It’s about having the engine running, doing various tunes to it and exploring various options of turbo control and turbo size.
“The results of all of that help determine the (Gen2 techncial) document,” Stuart told supercars.com.
One critical area of testing will be the development of a new engine management system with the extra inputs a forced induction engine requires compared to a naturally-aspirated unit.
“The engine management system is one area and then it is trying to understand the packaging, the cooling, the intercooler and all of that,” Stuart confirmed.
“We have to understand the packaging of the intercooler and how all of that is going to work with our current chassis.”
Supercars has made no secret of its plan to develop a prototype V6 engine, but Stuart said the development and build had been slowed by a number of factors.
They including the likelihood that Gen2 racers would not be appearing before 2018 and the technical department’s need to work with race teams on their more immediate homologation needs.
“I know we have been talking about this engine (since 2015), but we are not a race team and we are not a manufacturing team,” Stuart explained.
“Teams are still developing their current V8s and still trying to do whatever they can for that, so that keeps us busy along with whatever other projects the technical department does.
“The other side of team’s presenting engines for homologation is everybody wants it now and we work in as best we can with the teams and their timelines and if they think they have something that gives them an advantage they want to use it as soon as possible.
“But we have been able to clear a lot of the other work that we had to do and can now focus on this.”
