THE FACT THAT NASCAR’S SUCCESS TRUMPS ALL OTHER forms of motorsports in the United States proves that the concept of performance from efficiency still hasn’t fully caught on. Even with its steel tube frame and purpose- built chassis, the behemoth of a NASCAR Sprint Cup car weighs in at over 3,400 lbs. While other racecars and select streetcars utilize carbon-disc brakes or rack and pinion steering, the Sprint Cup vehicles stop with heavy cast-iron disc and caliper braking systems and steer with a clunky recirculating ball mechanism. Yes, these cars go fast, but doesn’t it sound like they could benefit…

Formula1 represents the cutting edge of automotive technology. While F1 performance may not be feasible in a streetcar, some of the amazing innovations pioneered for the pinnacle of automobile racing finds it’s way into production automobiles due to the trickle down effect. In the early 80s, Honda commissioned the world-renowned Italian design house Pininfarina to pen the lines of the HP-X concept car that eventually led to the design of the NSX, Honda’s first world-class exotic car. Produced from 1990 through 2005, the NSX featured numerous innovations that hail from Formula1 and was the first production car with an all-aluminum…

What is bulletproofing? In terms of high-performance engines, bulletproofing refers to increasing the power handling capacity of an engine beyond the desired power level. Depending on the design of the engine and the magnitude of the power handling increase desired, the bulletproofing process will vary. The parts and processes needed to build a Honda B20 and a Mitsubishi 4G63 to be bulletproof at 700whp are going to be different despite the fact that both engines are 2.0-liter, four cylinders with DOHC 16 valve cylinder heads. Additionally, the process and parts to bulletproof a Toyota 2JZ to support 800whp is going…

TRA-Kyoto’s Kei Miura has been busy at his workshop. After announcing the new Pandem series aero kits in October and showcasing several of the new kits at the 2015 SEMA Show, Miura released images of his latest creation on the company’s Facebook site on February 8. A new Rocket Bunny kit for the Honda EG Civic.  Although no text was included other than “coming soon” and some shots of an EG Civic hatch with Miura’s signature styling. Hopefully though the kit won’t cost more than the car.

Subaru proves that looks aren’t everything. The fact that most of the best looking cars also happen to be some of the fastest is not a coincidence. Usually, feats in engineering follow the mantra that beauty follows function, where designs that positively influence performance naturally present an attractive appearance. Subaru somehow pulled off the opposite with its 2016 WRX, a paragon of affordable fun, wrapped in a much simpler package than most vehicles of similar performance. Despite the changes in aesthetic direction from the previous generation WRXs, the experience from behind the wheel keeps getting better. Text by Cameron Parsons…

Over in our machine shop, we show you the benefit of using the dry ice to fit in your cylinder sleeves more easily. • Insert cylinder sleeves into cooler of dry ice and heat engine block to 250 ºF . • Remove engine block after 30 minutes of heating. • Use retaining compound on the block before inserting cylinder sleeves. • Remove cylinder sleeves from cooler after 30 minutes. • Slide cylinder sleeves into engine block.

IT’S A HOLLYWOOD CLICHE TO GET BEATEN IN A RACE, go back to the garage, make improvements and come back a winner. The fact is, this scenario is something that many can relate to and draw inspiration from. When the shortcoming is related to traction, even more clichés come to mind. Getting power to the ground has proven a challenge for generation upon generation of racers and enthusiasts. The quest for traction has prompted some to think outside the box, taking uncommon measures to achieve it. Thankfully, the results sometimes more than justify the frustration, effort and expense. Text and…

BOOKS HAVE BEEN WRITTEN ILLUSTRATING THE MATH, SCIENCE and design of suspension systems. In the case of coil-over suspension systems, buyers must consider price, application, construction and adjustment capabilities when selecting the best coil-over system for their vehicle. If the objective is to simply achieve a decent ride on a lowered stance, there are a number of options. The quality of the product will determine if it lasts for 10,000 miles or 200,000. If the objective is to tune a vehicle for maximum performance on the street or on the track, a higher investment will be required. Staff Report Price,…

HOLD ON TIGHT ENGINE INTERNALS TAKE A LOT OF ABUSE IN THE FORM OF HEAT, VIBRATION and friction. Keeping the engine internals together under these conditions requires strong fasteners.

PUNCH OUT THE BOXER AS THE SAYING GOES, THERE IS NO REPLACEMENT FOR DISPLACEMENT AND L.A. Sleeve has made it easier for Subaru owners to up the displacement of their EJ25 engines with its Big Bore Sleeve Kit. L.A. Sleeve’s kit is made from proprietary Moly2000 centrifugally spun cast ductile iron, a hardened material that can be bored out to a bore larger than the factory 99.5mm piston size. According to L.A. Sleeve, the increase in bore size can efictively increase the displacement of the EJ25 to 2.8-liters. In addition to the increase in engine size, the sleeve kit offers…

“I love this car! I’ll never modify it. It’s perfect, just as it is.” Many can relate to this sentiment, and probably even more will admit to making changes shortly after. But the urge to upgrade always seems to overtake practicality and complacency. T1 Race Development’s Tony Palo would be the first to admit it, since he started tuning and racing his R35 GT-R only two weeks after making that opening quote on his way home from the dealership.

Power, speed and no fear of defeat. This is the checklist of any warrior going into combat. Since its creation, VeilSide’s R-1 Street DRAG GT-R has faced challengers from around the world and none have been able to better this warrior on the quarter-mile clad in street trim. Bigger engines, more power and bigger bankrolls have not been able to dethrone this king of the street. Instead, the VeilSide R-1 has bettered all in the 1/4-mile confrontations and in challenges to be the quickest 0-300km/h street car in the world.

VETERAN RACE TEAMS OFTEN SEEK GREATER CHALLENGES TO PROVE A POINT– the seemingly unfeasible can be made a reality. Building a winning Formula D racecar that requires a RWD conversion in a timeframe of a few months would seem unfeasible. However, Papadakis Racing, with the support of Scion, TRD, AEM and driver Tanner Foust made it a reality. Text By Richard Fong // Photos by Michael Ferrara Stephan Papadakis is a name synonymous with import performance. Steph has built and raced some of the fastest import-powered vehicles in the world. Going from a dead stop to over 200 MPH in…
