the history editorialLaunched in Summer 2003 and published 8 times a year, Race Engine Technology is the brainchild of Ian Bamsey, the highly respected and award-winning motorsport
journalist of over 30 years standing.Ian and his team of industry experts
produce a unique, high quality, technical source of information that is widely read, referred to, and sought after, by its dedicated readership of design and development engineers, across the entire global powertrain industry.
RET remains one of the few magazines in motorsport entirely dedicated to the technology and innovation that drives competition forward.
At the heart of this authoritative publication are in-depth research insights that probe significant contemporary projects, with informed analysis backed by professor peer review and critique. Race Engine Technology (RET) features all aspects of technological developments, in turn creating a truly must-read title among the global racing industry. We cover many and varied types of feature and here are a few examples:
Grid The ‘grid’ section is an analysis of recent, technological powertrain-related news from the world of motorsport. Rather than just present the news as it’s reported, the editorial team at RET take one further step in order to outline the wider ramifications of the development at the heart of the story.
Engine dossierAt least one and more often than not two ‘dossiers’ will appear in every issue of RET. Our signature feature, the ‘dossier’ is an incredibly detailed look at a high-profile racing engine, revealing many secrets of the technology that are simply not reported anywhere else.
Race Engine Digest (RED)Each RED provides a succinct profile of a newsworthy race engine, outlining its design and development, with a full specification provided and also a list of component suppliers. Coverage includes all forms of motorsport, from Global RallyCross to Le Mans; from Midget racing to IndyCar.

Computational fluid dynamics (CFD) is a process for solving
the partial differential equations associated with fluid
flows in a continuum (the Navier-Stokes equations are
most commonly solved). It is an exciting field, in that such
a direct link can be drawn between the complex pure mathematics so
many of us struggle to remember, and a direct practical solution to an
engineering problem.
The study of fluid dynamics is essential to developing any effective
racing powertrain. While one immediately thinks of the behaviour of
the air-fuel charge through the engine, there are many other aspects of
the powertrain where understanding the fluid dynamics involved can
consuming, however, as a prototype must generally be constructed for
every design that is of interest, and then the physical testing conducted
– which of course requires not only investment in the relevant
equipment but incurs overhead costs in order to maintain and operate
it. The alternative then is to turn to computational methods in order to
predict the effect of the design variable in question.
CFD is a relatively recent field, but it has seen some incredible
advances over the past few decades in the techniques used and
the accuracy of the results that can be obtained. The fundamental
principle is to divide a domain or continuum of interest into discrete
elements or cells that can be solved using the relevant equations and
one of various finite element or finite difference-type approaches. This
requires not only a knowledge of the domain’s geometry – for example
the inlet port, valve and combustion chamber geometry – but also the
properties of the fluid of interest, such as the density and viscosity of
the air, fuel or oil.
bring a measurable performance benefit. Various methods of doing so
are available: for example, flow benches or visualisation techniques
such as shadowgraphs or particle image velocimetry allow an engineer
to either ‘see’ the flow of air or fuel in the engine or to measure the
difference in inlet port pressure drop, say.
These techniques ultimately allow us to judge how effective a design
is, compare it with one or more alternatives and select the best option
for a given application. Designs that survive these assessments then
continue to dynamometer testing and ultimately on-track testing or
racing, where their benefit is ultimately determined.
The realities of such empirical testing are expensive and time-
Along with this basic input information, a set of boundary
conditions such as inlet air pressure/velocity and temperature is also
needed, as well as a target goal or parameter of interest – outlet air
pressure, for example. A conventional CFD study would then compare
several designs of, say, port shape or valve geometry, solving the
problem for each design option and comparing the results in order to
select the best candidate design(s).
Software and implementation In the simplest case, CFD simulations are concerned only with steady-
state problems, and work with idealised fluid properties. The equations
that need to be solved for such a scenario are relatively simple and
allow very efficient computational runs, so a lot of design candidates
can be compared quickly. Indeed, for an initial look, such a simplified
model of a much more complex unsteady (turbulent flow) problem is
often worthwhile if some of the design candidates can be ruled out
immediately or promoted to more detailed analysis.
Solving higher-order equations that describe turbulent flows,
those with a transient behaviour or involving compressible fluids,
are naturally more computationally expensive, although modern
solvers can process such problems on up-to-date hardware almost as
efficiently as steady-state problems could be solved in the past.
Advances in CFD techniques and accuracy are closely linked to the
available processing power. Whereas in the past, 2D or 1D simulations
were often used to minimise the computational effort required,
3D simulations are now common, as they provide more accurate
results and a greater appreciation of the flow behaviour, and can be
processed as quickly as a 1D or 2D model. There are also some cases
(such as combustion chamber turbulence) that are asymmetric and so
can only be studied properly using 3D simulations.
The increase in processing speed is mainly thanks to the advent
of 64-bit computing, particularly multi-core processors or high-
performance computing clusters with large numbers of processor
cores and large quantities of RAM. Depending on the application and
the type of simulation to be run, software can also take advantage
of graphics processing units (GPUs) rather than conventional CPUs
and can be scaled to use up to 36,000 cores at around 85% of the
efficiency of running on a single core.

Although still a fairly recent development, CFD is leaping ahead in its power, affordability and ease of use, as David Cooper explains
How’s it f lowing?

Lawrence Butcher finds out how this small team dealt with the 2014 rule changes to keep it in contention
PROFILE : FORCE INDIA VJM 07
t
Force India has a well-earned reputation in Formula One as
a strong midfield contender. In 2014, the team finished sixth
in the Constructors’ championship, just behind McLaren.
The season also saw the team grab its first podium since
2009, gaining third place at the Bahrain GP, and its cars consistently
finished in the top ten for the rest of the year. What these results do
not show however are the challenges faced by a team which, by its
own admission, has nowhere near the resources of the front-running
outfits yet has still managed to take the fight to the larger teams on a
regular basis.
So how did this small team, based just outside the gates of the
Silverstone circuit, handle the sweeping and complex rule changes
introduced in 2014 to produce a reliable car that was on the pace
from the first race? We talked to the team’s technical director, Andy
Green, at the 2014 British Grand Prix, about some of the aspects of
the 2014 VJM 07. With the power unit and controls coming from
Mercedes, and the transmission from McLaren, the conversation
focused on the work undertaken to produce the chassis and
aerodynamic packages.
Unlike much of the PR-driven rhetoric that Formula One is famous
for, Green was refreshingly frank about the strengths and weaknesses
of the VJM 07. “I think that after the first few races, even though we
had been getting the results, the car is not the best one we have ever
done,” he said. “It has some handling traits that we are not happy
with and we have been looking to address those. But it is nowhere
near where we need to be, and the feedback from the drivers is fairly
unanimous on where we need to be with it. We have not been sitting

Volume 10May 2016 Formula One underwent its biggest change for decades in 2014, when the powertrain rules were radically overhauled. Turbos are back and new energy recovery system technology has been introduced. This has all addedup to an absolutely fascinatingtechnological landscape. 2014saw Mercedes grab the initiative, leaving Renault andFerrari powered teams playingcatch up. For 2015, Mercedescontinued this dominance.Moving into 2016, the technology used will furthermature, but with the regulationspermitting a steadily reducingnumber of changes year onyear, the challenges of the 2015 season, and the new developments for 2016, will be covered in depth in F1 Race Technology.

Motorsport is undergoing a revolution, the most substantial of its long history. Widespread concern over consumption of fossil fuels and greenhouse gas emissions have led the motor industry to exploration of alternative fuels and hybrid and even all-electric vehicles. Motorsport is following suit, to the extent that alternative fuelled and hybrid vehicles have already won prestigious events against conventional racecars, while 2014 saw the arrival of the first all-electric FIA series, Formula E. Alternative Race Technology is dedicated to the analysis of these new technologies that are starting to change the face of motorsport. The future is here now; explore its exciting novelties through this unique technical publication!
Volume 10September 2016
2014 marked the beginning of a new era in endurance sportscar racing, with major regulatory changes in the top LM P categories. Thanks to the presence of four major manufacturers in the LM P1 category, each approaching the new regulations with a different concept, 2015 was an even greater feast of innovation. We had Audi, Toyota and Porsche refining their respective hybrid cars and Nissan joining the LM P1-H fray. Lap times tumbled and Porsche toppled Audi from the top of the endurance racing pile. For 2016, performance will no doubt continue to improve, while new GT cars from Ferrari and Ford will spice up the rest of the field. 24 Hour Race Technology will bring in-depth analysis of these new developments.
Volume 7November 2016
Shock and awe is the most appropriate description of drag racing; no other racecars on Earth come close to Top Fuel Dragsters in terms of sheer power and brutality. Beyond the seeming simplicity of these savage machines, there are some extreme engineering challenges that tax teams and engineers. Though drag racing majors on brute force, the most subtle setup changes can make the difference between a record-breaking run or breaking traction and smoking the tyres. The diversity of machinery at a drag meet is enormous, making the sport a hotbed of engineering ingenuity. Drag Race Technology will investigate the imaginative solutions racers find to gain an advantage over the guy in the next lane.

“I recommend your magazine to everyone in the paddock and every person that has signed up for your magazine has thanked me for informing them of your publication. We all think your magazine is head and shoulders above all others.”
“Everything in RET is excellent! When I’m working on anything that relates to what you have written about before, I read through the relevant article again, paying particular attention to the appropriate advertisers on the next few pages that under normal circumstances would be hard to track down. Many thanks and just keep it up with LOTS more of the same!!”
“RET is an exceptional source of information on the current technical status of activities in the world of racing engines. I also believe that it is an extremely valuable historical archive of that technology. Given the strong urge in the motorsports world to confidentiality and secrecy, there is a genuine danger that technical information will go unrecorded and be lost to future generations. RET, under the guidance of Ian Bamsey, provides that record that would otherwise be lost.”
“Congratulations on ten years of RET! You continually achieve a very high standard of reviewing engines and engine components from a highly technical perspective. We have learned a great deal from your articles.”Dr. Andrew Randolph – Engine Technical Director, ECR Engines
“Congratulations on 10 years of the Race Engine Technology magazine! I really enjoy every single issue of it and it is fantastic that such an interesting magazine exists.”Axel Wendorff – Head of Powertrain, McLaren
“Just to say that it’s an excellent series of publications, something to really look forward to every few weeks.”
“I don’t know how you could make RET any better. Just keep doing what you’re doing and that will keep me buying the magazine.”
“Your research is first class.”
“Again, thank you for an outstanding article. The engineering/design side of racing components is second to none.”
“Excellent, one of a kind, it is great to read about industry tech and insight to development.” “I think your magazine is excellent, and a very good source of both information and suppliers (adverts).”
“The “focus” articles that look at specific components are great. They could be compiled into a text book. In fact, I make copies of them and keep them in an easy to reference binder in my office.”
“Keep up the excellent technology focus articles.”
“The technical detail you provide about race engines is just plain not available from any other source.”
