Engine chief on Minardi, Red Bull and 20,000RPM V8
At Imola this weekend Minardi and Red Bull will, for the first time this year, race with the same specification Cosworth engine. The engine builders Managing Director Tim Routsis explained the latest changes and spoke about future developments at the company.
Q: What are the key advantages of the TJ2005 engine, particularly in terms of power and weight, relative to the CK2004 engine that Minardi have used until this weekend?
Tim Routsis: The latest TJ2005 engine represents significant gains over the CK engine: peak power increase of more than 60BHP, engine speed increase of 500RPM, engine duty cycle increased (more power for greater period of running), engine life extended to cover two events (1300km nominal) and reliability improved, engine centre of gravity more than 50mm lower, engine stiffness significantly increased, high level of integration with car design.
Q: Will it be track tested with the team prior to Imola?
TR: The first TJ2005 powered Minardi PS05 chassis successfully completed over 200km at Mugello last week without problems.
Q: Are there any differences between the TJ2005 engine that Red Bull Racing is using and the Minardi unit?
TR: There are no significant differences between Red Bull and Minardi engines. There are always a small number of team specific components to suit a new car installation but other than that, the engines share the same specification.
Q: Are there any further upgrades planned for either of the teams this season?
TR: A Series 12 engine is scheduled for introduction with Red Bull Racing at the Indianapolis GP (or Canada GP depending on when the scheduled engine change occurs).
Q: Was this a scheduled upgrade?
TR: Yes. This engine is currently under development and will deliver significantly more power and revs over Series 10. It will be exclusive to Red Bull Racing and a development version (Series 11) with a gain of 30BHP and a maximum engine speed of 19,000RPM has already been successfully track tested by Red Bull.
Q: How is Cosworth overcoming and addressing the challenge posed by next year's V8 engine?
TR: Work is well underway on a new V8 engine to comply with the 2006 FIA Formula One Technical Regulations. The fact that these new regulations are much more restrictive and certain engine dimensions are constrained has a significant impact on the focus of the engine design work. By nature, this offers both an opportunity and a challenge.
Q: Do you already have a V8 engine on the dyno and can you disclose power and rpm figures?
TR: Development engines have been running on the dyno for quite some time and we are very happy with the results so far. Power figures cannot be disclosed for obvious reasons but we can confirm that we are routinely running to 20,000RPM.
Q: When do you expect to confirm customers for 2006?
TR: Negotiations with potential customers for 2006 and beyond are ongoing.
Q: Cosworth seems to have made remarkable progress in terms of performance and reliability since last season. How has this been achieved?
TR: Cosworth has made significant changes to the way in which the company (and specifically the F1 engine project) operates over the last 18 months. We are now seeing the results of these changes and everyone at Cosworth is proud of what has been achieved.
