Tuned In High Performance Academy

Can 3D printed parts hold up in an engine bay or elsewhere on a car when compared to the use of lightweight aluminium or similar, or is it still just technology best leveraged for prototyping?

Grant Luttinen of Intamsys helps us understand some of the pros and cons of additive manufacturing, what is required when it comes to software and some options out there for printers as a hobbyist or professional.

We take a quick look at printing options from $1,700 to $150,000 USD, as well as printing media/materials that start from $20-40 for a spool of ABS plastic and then go to $100, $600 or more for nylon, PEEK carbon fibre and 3D printed metal options.

Accusumps. Whether you're a motorsport enthusiast, a professional racer, or simply keen on advanced car maintenance, this video covers many of the common questions on how an Accusump can enhance your engine's reliability and performance and bridge the gap between a wet sump and (let's be honest, expensive) dry sump upgrade.

Iann Criscuolo from Canton Racing Products answers some of the common questions we all have when it comes to how an Accusump works by filling with oil and supplying it via manual or electronic control that can be based on RPMs, g-force and more, how easy Accusumps are to setup with their optimal -10 ('dash 10') hose sizing recommendations and how long you can expect oil to be supplied at 7-10 psi of pressure.

It's important to note that you can set your Accusump to fill much faster by using higher pressures, but that also means the oil will be supplied to your engine much faster, so racers need to find a balance that suits their application whether that is drift, drag, circuit, offroad racing or something else.

The formula for building a big-power LS is pretty simple — but things get a little more complicated when the motor needs to produce all that power for sustained periods of time in applications like drift or circuit racing. In this episode, we sit down with Mitch Pullen of Pullen Spec Engines, who specialises in putting together ultra-durable LS builds to discuss the ins and outs of these motors and much more.

Thanks to his father’s involvement in motorsport, Mitch Pullen started young, assisting in the pits and moving into the karting world at 10 years old. By 14, he was building engines, creating his own wiring harnesses, and figuring out fabrication. It’s probably no surprise, then, that he left school fairly early to learn everything he could about nearly all aspects of motorsport engineering.

Although Mitch is a jack of all trades, he decided to focus on performance engine building, and this now sees him running the well-respected and very busy Pullen Spec Engines based out of the Gold Coast in Queensland, Australia.

In this conversation, Mitch goes into detail about how he builds LSs, discussing their inherent weaknesses and strengths and the work that’s needed to create a motor that can sustain high horsepower and high RPMs for more than just a pull or two on the motorway or a run down the strip.

Mitch is also well known for his unique S13 Silvia competition drift car, which runs a massive Roots-style blower sitting atop a Dart iron-block LS. There are a few obvious questions when it comes to this setup — why bother with this type of supercharger, how does it behave in a drift car, and can you even see anything when you’re driving? Mitch answers all these questions and more.

The conversation finishes with some great discussions around car setup, forged vs cast engine parts, performance aircraft engine builds, and more.

Why can't you tune any ECU however you'd like or fit any aftermarket ECU to your vehicle without a care in the world?

Ryan Nicholls Powertune Australia answers these common questions and more in relation to what can be done with the right skill set and tools, in this case, MoTeC's M1 Build and knowledge of C# (C Sharp) development language.

Some key takeaways from this chat include some insight into CAN Bus, LIN Bus and FlexRay, plus the fact that reflash tuning is not equal for all platforms, and some are much better developed than others. Ryan also mentions how you are often relying on an interpretation rather than an absolute when it comes to reflash tuning software vs the lack of OEM information, as well as sharing encouragement from Ryan for anyone interested in learning the skills he has to do so, even at a hobbyist level.

This interview was recorded at GTR Fest Australia, where we somehow managed to film more about EVOs and MoTeC ECUs than GTRs, and had a ball doing it too.

Hot rodding has been and always will be a HUGE part of American car culture, and electric vehicle conversions are bringing a wider range of options to the street.

Why do a Tesla swap and not use aftermarket components? What happens to the 12v electronics including the lights and indicators without an alternator or the brakes without engine vacuum to operate with?

At SEMA, Casey Loter gives us some answers to the above and insight into this customer's 1959 Chevy Apache Fleetside electric vehicle conversion, which is powered by a Tesla Model S motor and battery pack that's been rehoused for better packaging and suspension options.

While Tesla parts are used, they are scrubbed clean of Tesla's limited software by companies like EV Control, who can easily tap in remotely for this process. An Orion battery management system is used along with Stealth EV charging components and a cooling system for the charger and batteries up from and motors in the rear for this specific Chevy Apache conversion.

Simon Longdill wasn’t impressed with the engines available to him in his class of racing, so he built his own. On this episode of Tuned In, we catch up with the man behind Synergy’s small-capacity, ultra-high revving, 400+hp V8s to talk through the ins and outs of these screaming motors and much, much more.

While “building your own engine” in the literal sense might sound like a more-than-daunting task for most, with a Ph.D. in mechanical engineering, this was something that Simon Longdill was more than capable of. Limited to 2.4 litres in his Speedway midget class, Simon hatched an idea that would go on to become a full-time business.

Using two sets of 1200cc Kawasaki ZX12R cylinder heads and barrels, Simon got to work creating a vicious 2.4-litre V8 that would go on to crush the competition on its debut in New Zealand, before doing the same in Australia, then doing so well in the US that the rule book was changed and Simon and his team were never invited again. These days, you can find Synergy V8s of differing capacities and power levels motivating all manner of race (and a few street) cars across the globe.

In this conversation, we get down into the weeds of this fascinating engine’s story, answering all the big questions around the 11,000 RPM screamer’s inner workings and development journey. Simon didn’t just stop at the first iteration either — these motors have been continuously developed over the last decade as the tech has improved, new lessons are learnt, and big improvements are made.

With some fascinating looks into Simon’s side projects that include a 400hp BMW 1000RR two-litre V8 built for Bonneville, an 800hp twin-turbo Synergy V8 for Pikes Peak, hydrogen power systems, and plenty more, this is a tech-heavy episode that’s going to please anyone with an interest in serious automotive engineering.
