It's unusual to see a new V10 engine go into production these days with the V10 and V12s engines of previous Formula 1, Prototype (LMP) and Grand Touring classes long being replaced by V8s and V6s, but Rodin Cars are bucking the trend with their RC.TEN engine project.

Mike Gartrell of @RodinCars runs us through some of the ins and outs of this V10 project, including how partners like Neil Brown Engineering have helped with the design and @PanklRacingSystems with production. However, with low quantity runs costing as much as €45,000 ($49,000 USD) per crank, the long-term plan is to bring the manufacturing in-house to their New Zealand base.

The 2024 World Time Attack Challenge was the first outing and test of the engine as part of the Rodin SINTURA project, a controversial carbon monocoque chassis that has been given an exemption to compete at the event.

RC.TEN Specs:

• 3998cc - (244ci) 72° naturally aspirated V10
• 12,000rpm
• 185bhp/litre
• Cast Aliminium head and block with Nikasil coated steel liners
• 86mm bore, 68.8m stroke
• DOHC
• Bosch direct injection system running 102 RON fuel
• 15:1 compression ratio
• 720bph @ 11,000rpm - N/A goals
• Twin Turbo Capable
• 160kg
• Link G5 ECU & electronics package

For most builds, gone are the days of zip-tying an old Bosch 044 fuel pump into place with a healthy dose of sealant, partly because these days there are simply more options but also because builds have gone from 400hp up to 1000-1500hp+ for many performance street applications, and the budgets have increased to match.

Kevin from Frenchy's Performance Garage runs us through some of the main considerations that go into some aftermarket solutions, including their own for the GTR platform being used as an example.

The 3 main problems Kevin and the team hope to solve with an aftermarket fuel pump setup are:

• Surging (lack of fuel supply)
• Mounting (lack of tidy solutions for popular pump options)
• Powering (easy to source wiring connectors)

We'll take a quick look at these points and touch on how aftermarket solutions can be integrated into your stock fuel lines and what exactly it is about stock solutions that don't work on many street-turned-race cars.

Have you ever wondered how small aftermarket companies are able to drastically improve on parts from OEMs and huge players like Garrett or Borg Warner that have massive R&D departments and even bigger budgets behind them? If you ask this week’s guest, Robert Young of Forced Performance and Xona Rotor, he’ll tell you: “We try harder and we’re better at it”.

Of course, the reality isn’t quite that simple… Luckily we’ve got a full two hours to dig into this topic and many others surrounding the world of performance turbocharging.

On this episode of Tuned In, we start by looking at how Robert became the turbocharger guru he is today as the name behind Forced Performance and Xona Rotor — the latter formed in partnership with Greg Jones of Tial Sport.

This is a story that involves years spent studying physics and mechanical engineering, as well as hands-on experience at turbo shops and with his own projects that ranged from old Ford Fairlanes and fast air cooled VW drag cars, to the early DSM drag world of rapid Mitsubishi Eclipses.

Both Robert’s companies produce ultra high performance aftermarket turbochargers and turbocharger components for a range of vehicles, and as one of the main brains behind these sought-after products, Robert is an absolute goldmine of turbo knowledge.

This means that the conversation quickly dives very deep into the world of boost, discussing a huge range of topics — journal vs ball bearing, billet compressor wheels, compressor maps, turbo sizing, and so much more.

This episode is a true turbo tech info dump in the best way possible. If you have any interest in going fast, don’t sleep on this fascinating conversation with a big brain of the forced induction world.

Many people think driving skills can only be a 'gift you either have or don't' and something that doesn't need any work or effort to build and maintain. Those people are wrong.

Mike McGinnis of Innovative Tuning shows how 'the science of speed', aka data analysis, is used by both professional and amateur (Pro-Am class) drivers, using Cole Powelson of LYFE Motorsport and Jeremiah Burton of Donut Media & Big Time as examples at the World Time Attack Challenge.

🔥 The LYFE Motorsport R35 GT-R boasts 1200hp from a 4.1L VR38DETT engine and MoTeC electronics package including their i2 Pro data analysis software. This setup is designed to optimize the car's performance, especially in competitive environments including WTAC and hill climb events. The vehicle features twin Garrett GTX3076 turbos, which contribute significantly to its power output and performance capabilities.

Despite the advanced electronics and data systems, Mike highlights that valuable insights can still be gained from a more limited range of sensors. In some cases, even the original equipment manufacturer (OEM) sensors can be leveraged for purposes different from those initially intended. This approach allows for flexibility and innovation in data collection and analysis, potentially improving vehicle performance without the need for extensive additional equipment, making it much easier to get started with.

There are also a few helpful tips here on how to best leverage your data including why you might consider overlaying your data based on distance rather than time and where pro drivers can pick up huge amounts of time with their more aggressive braking confidence, a skill that is certainly learnable with some data, rather than just 'butt dyno' opinions.

When pushing OEM engines to their limits, factory components often fall short. Platinum Racing Products in partnership with Crest CNC addresses these issues with their new cast cylinder head for the Subaru EJ series.

✅ Solving EJ Series Problems
Known for head lifting and cracking, the EJ20 needed a robust solution. PRP's cast head offers improved intake port spacing for larger valves, thicker head material, and a redesigned exhaust port for better flow and reduced back pressure.

☝️ Why Cast Over Billet?
While billet is great for prototypes, casting is ideal for mass production, offering better thermal expansion properties and consistent quality.

🔥 Enhanced Performance
The new design supports 14mm head studs and versatile coil mounting options, making it easier for high-power builds. Customizable port designs allow for CNC porting up to 420 CFM, ensuring optimal performance.

Creating high-end race cars and parts for a living is a dream for many of us, but how do you turn that dream into a reality? We don’t have all the answers, but we can pick the brains of the people who’ve pulled it off, like this week’s guest, Joe Scarbo.

Joe Scarbo of Scarbo Performance and Scarbo Vintage began his love affair with all things motorised like many of us — young and elbow-deep in a deconstructed radio control car trying to fix and improve it. This episode first covers Joe’s early days as he gained an appreciation for all things automotive through his love of both RC cars and go-karting. After a few too many crashes in the kart, Joe steered his passions towards the engineering side of the game, and began building his first car completely from scratch.

With little experience and zero computer power, Joe designed and built a four-seater 350 SBC-powered off-road sand car that’s still hitting the dunes to this day, despite it being finished before Joe was even out of his teens.

While he was still studying mechanical engineering at university, Joe found himself employed as a fabricator and machinist at a high-end race shop. From there, his career began to snowball as his design skills became more and more in demand. We dig into the design side of Joe’s career in this conversation, discussing the creation of strong and light wheels, chassis’, and everything in between.

After that, Joe talks us through different fabrication and manufacturing processes, discussing some of the pros and cons around CNC, water and laser cutting, notching, materials, and more. This chat also goes into the business side of the equation as we attempt to answer age-old questions like: how do you accurately quote your work? And when is it better to just outsource certain jobs?

The star of this episode, though, is undoubtedly Joe’s current passion project, the SV1 Rover. This monster off-roader is a marvel of engineering, and a machine that Joe has labelled the world’s first “hyper truck”. Whether he’s right or wrong about that we’ll leave up to the listener, but either way, the details we get into on this 30-inch travel go-anywhere-at-very-high-speeds beast is well worth a listen. Find out how it was designed, what powers it, what it’s capable of, and much more in this episode of Tuned In.

What do you do when you're bored of being one of the fastest 5-cylinder drag cars in the world? Double down and reach for a V10 is the answer Hank Iroz of Iroz Motorsport went with, and we're glad he did!

Use ‘PODCAST75’ for $75 off your first HPA course here: https://hpcdmy.co/hpa-tuned-in

With world-leading experience gained on the RS3 platform, the switch to the Audi R8 V10 is a similar area for the Iroz team, and with the R8 and Huracan platforms being similar and very active in the drag racing world, it's a great platform to be active with.

It was early days for the car during this interview with a lot of work done but limited testing yet, however, the car was setup with weight balance as a primary focus, and as such the Xona Rotor X5C TR9980 performance turbos were not located out the back as we commonly see, but rather don't he side where some cooling is usually found, and a GT4 chassis was used as the starting point given they are already well caged and come with all the sensors you need, and probably some you don't for drag racing.

With an AMS Performance and Dodson parts package plus a MoTeC electronics system as part of the puzzle, we're interested to see where this project heads in the future.
