800HP M119 5L V8 turbocharged Group C endurance racing champion.What goes into a 400kph/248mph Le Mans 24 Hour endurance race winner and how do you keep such a car period correct, but also track fit? The Group C Sauber chassis and Mercedes-Benz ‘M119’ powered C9 managed the first win at the 1989 Le Mans 24 hours for Mercedes since 1952 with a 1-2-5 finish, and also wins at all but one race during the entire 89 World Sportscar Championship. If that doesn’t impress you, then we’re not sure we can be friends anymore...Want to learn how to build your own performance vehicle?

The RPV8, a 400-500HP Suzuki Hayabusa based V8 engine, is used as an example to help explain compression ratios and squish with James Pinkerton of Radical Performance Engines.The N/A Hayabusa V8 used in some Radical Sportscars models runs a 12.5:1 to 13.5:1 ratio on 98 RON pump gas, with only the higher ratio becoming prone to knock, aka detonation, before minimum timing for best torque (MBT) is reached. In this interview James explains why he would choose more ‘squish’ over a higher compression ratio along with exactly what squish is and why it is so important for a complete fuel burn not just to make as much power as efficiently possible, but also to reduce the chance of detonation which can cause terminal damage to your engine very quickly in some circumstances.Want to learn how to build your own performance vehicle?

What do YOU know about wet, dry and Accusumps?Maintaining a high-pressure supply of oil is a big problem for engine packages that were originally designed for road use, but find themselves being worked hard on the track in vehicles with sticky slicks and consistently pulling more G’s than the factory engineers ever planned. David Mountain of MounTune explains some of the issues that are caused not exclusively but namely by lateral g-Forces while cornering for circuit racers, but also apply to horizontal forces while accelerating and braking for all you drag racers out there.Want to learn how to build your own performance vehicle?

What is this? An ECU? A PDM? A Wideband Controller? A Datalogger? Haltech have just released the Swiss Army Knife of ECUs and they reckon it does all of the above! At this year's Performance Racing Industry show we got a first hand run down on the new device from industry genius Andy Wyatt, who you might recognise from the Adaptronic ECU brand as well.Want to learn how to build your own performance vehicle?

Reducing the wear of your engine components while increasing reliability and performance is a constant battle for casual enthusiasts and motorsport professionals alike, and Gary Huffman of Calico Coatings runs us through some of the options they offer to help us reach this goal.We’re going to discuss some of the main engine components you might consider coating such as valves and piston wrist pins, along with some you might not like bearings. The ability for clearances and oil weights can be advantageously adjusted thanks to the extra lubrication Diamond Like Carbon (DLC) and Chromium Nitride (CrN) PVD coatings provide is touched on along with how the environment a vehicle is racing in, such as NASCAR or offroad racing can impact what coating is used.Want to learn how to build your own performance vehicle?

Get the lowdown on how Turbosmarts new electronic wastegates are going to change the boost control game in the aftermarket industry including why this offering is superior to what you can currently get your hands one from OE applications, which were never manufactured with the idea of running being able to withstand 60psi to 150psi of backpressure depending on the wastegates physical size, which of course depends on your setup.Want to learn how to build your own performance vehicle?

Shane T has a 3000HP fever and the only prescription is more boost!When you want to produce 2000HP from a turbocharged 4 cylinder engine it is logical that you’re going to lean heavily on your turbo setup. Shane Tecklenburg, the Mazworkz Racing Engines and Tekno Toyz team reached this goal with their MoTeC controlled 88mm turbo setup some time ago, but when reaching for 3000HP it was evident a single was not going to cut it.Want to learn how to build your own performance vehicle?

What is the design and thought process behind aftermarket piston manufacturing for relatively new engines to the scene like the BMW B58 found in the Toyota A90 Supra?At PRI Barry Pettit from Mahle Motorsport took us through some of the considerations they put into their forged A90 Supra B58 engine pistons. Interestingly even with the idea in mind that their customers would want to crank up the boost and take things to 1000HP and beyond, unusually, these forged examples are LIGHTER than the OEM versions, yet stronger.

4WD applications give traction advantages in most motorsports however in the world of drag racing it can sometimes be hard to dial in to ensure that you don’t end up with too much.Running a FuelTech FT600 ECU and a 2.2L stroker 4G63, this Mitsubishi EVO 8 aka KNG 4G has already run a 10.50 at 150mph on a more basic setup and with a solid 650kw (870hp) at the moment there is plenty of room to turn the wick up as the driver's experience and the build progress.Want to learn how to build your own performance vehicle?

Quad Rotor vs V8, Procharger vs Natural Aspiration and more.It's hard to nail form and function, but Carl Thompson has it down to a fine art when it comes to drift builds between his old 1300HP 26B 4-rotor Aristo/GS300 build and this high compression 'small block' @Mast Motorsports 454ci (7.4L) LSX based V8 Nissan S15 Silva one that is another work of art. Even if you are a solid rotary fan it's hard not to appreciate the same level of detail and perfection that has gone into this LS based S15 build.Want to learn how to build your own performance vehicle?

Nissan Skylines are one of the most popular cars from the ’90s and 2000’s for modification, but throughout all those years we’ve never seen one quite like this.Capable of 975HP at 28PSI, Dennis O’Malley had the XR32, a Ford Barra powered R32, dialed back to 850HP at 23PSI for this years Turbosmart Flying 500 at the World Time Attack Challenge in order to make the car a little more ‘user friendly’, but unfortunately didn’t get a good run due to some ongoing fuel pressure issues. The Micks Motorsport built Barra runs Siemens Deka 2400cc injectors, Haltech Elite 2500 ECU, Ford Falcon T56 box with S1 Shifter, forged internals and a Plazmaman Plenum is used along with a 6 piece cast manifold, but due to the nature of the swap pretty much everything else has been custom made to fit.Want to learn how to tune EFI?

Learning how to tune a 7 second, 1800HP world record holding drag car!With no set recognized training pathway to becoming a professional EFI tuner, it’s hard for some starting out to see what they need to do to reach their goals within the industry. At TX2K Devin Schultz of Boostin Performance talked Andre through how he went from twisting spanners on simple builds as an internet-less 16-year-old through to tuning the Red Demon, the World's Quickest and Fastest AWD Mitsubishi with a 7.047 @ 204 MPH record as well as separate blistering 215 MPH run down the quarter.
What considerations go into tuning a 1300HP EV such as the Palatov D2EV?While electric vehicles (EV's) have long been touted as the future of the performance world for a long time by many, the reality is between the costs, lack of aftermarket support and products that are not suited to motorsports have kept us waiting.Want to learn how to tune EFI?
