Project Tundra: Fixing the Brakes with Stoptech

by Mike Kojima

So as we alluded to in our last article, our powerful supercharged Tundra without a limited slip was continually activating the Trucks electronic nannies.  With the more powerful engine, the electronic LSD was working the rear brakes constantly trying to keep one tire fire under control and with the added cornering forces that our bigger tires allowed, the stability control was grinding away at the front brakes in tuns all the time.  The electronics were probably causing the brakes to be used at twice the normal rate.

We had tackled some of the issue by limiting body roll with a Sequoia front and TRD rear anti sway bar and turning up the stiffness of our King Adjustable shocks.  Adding an Auburn Gear Limited Slip Differential also helped a lot to keep the electronics from grinding away at our brakes.  However our brakes and rotors were shot with the rear brakes worn to the backing plates and we had to replace those ASAP.

We turned to Stoptech for some help in the brake replacement department with some new rear sport rotors and some less aggressive brake pads in the hopes of reducing brake dust and rotor wear for this brake service period

Jef Groff's Castro Motorsports LSM3 Drift Car

by Jonathan Lawson

Headed up by Chris Castro, Castro Motorsports has a knack for putting out some high-quality work. If you haven’t seen the airbox on Pablo Mazlumian’s Project E46 M3, take a moment and give it a gander. It’s a beautifully crafted piece of art. Castro Motorsports is full of true die-hard enthusiasts with performance oozing through their blood. They do everything from custom fabrications to motor swaps and big-turbo builds, and speaking of motor swaps, who wouldn’t love flinging an LS3-powered E36 M3 around? Well, drifter extraordinaire and professional stunt man Jef Groff sure doesn’t mind…

Truck? Did you say TARGA TRUCK!

by Frank Ewald

For about a year now this 1971 GMC 1500 Long Box has been known as the Targa Truck. Mark Bovey and navigator Miles Markovic participated in the Classic category and finished in 2nd place. This truck has gone through more life cycles than Disney ever thought when they penned the song “Circle of Life”. It has been a farm truck, a teenager's cruising truck, a drag truck, a land speed record candidate truck, an autocross truck, a family hauler, and most important, at this time, a Targa Truck. When you hear the Targa Truck you are just in awe of the vibration inducing bass notes which pour out of the side exit exhaust. Lift the hood and you see a massive engine. It is a Chevrolet Performance LSX Race Block with 427 cubic inches that has been built for endurance and power.

An Inside Look at mountune's GRC Ford Duratec Engine!

by Mike Kojima

The current engines used in today's GRC Rallycross racers are some of the highest stressed production based engines in all of Motorsports.  Only Import Drag Racing engines see more stress and perhaps no production based race engines not even Time Attack engines are stressed for as long a period of time as Rallycross powerplants.

Breathing through a 45mm restrictor that limits power to "around" 550 hp, the mountune Ford Duratec puts out 625 lb/ft of torque.  Because of the restrictor, the Garrett Turbo pumps in 45 plus psi absolute of boost to make that power, generating an amazing 3200 psi of cylinder pressure.  To put this in perspective, this is more cylinder pressure than the Audi LMP1 Diesel!

Quick Chat: Nasa Rally Sport's Anders Green

by Per Schroeder

If you ask anybody under thirty years of age about the sport of Rally, you’d be hard pressed to get an answer that’s doesn't include something about Ken Block.  Thanks to his not-quite-rally-and-not-quite-autocross online videos, he’s mashed the two most esoteric motorsports into something that doesn’t really exist, but is now “Rally” to the masses.

Project Viper GTS: Part 2 – General Maintenance

by Billy Johnson

Before thoroughly enjoying the purchase of a used performance car, it’s important for the enthusiast to go through some routine maintenance items.  We prepare our 1997 Viper to be driven by changing the oil, coolant, spark plugs, wires, and go through a few miscellaneous items.  We then install an aftermarket temperature gauge to monitor how hot the V10 operates and to test the accuracy of the factory gauge.

Project E39 M5, Part 2: Installing and Testing the Corsa Performance Exhaust

by Martin Gonzales

After ensuring we could stop our newly acquired fun-machine in a previous installment of Project BMW E39 M5, it was now time to let some ponies loose! Our goal; produce more power while maintaining the “quite refined” feel of our performance sedan. It’s no secret the S62 power plant in the BMW E39 M5 was extremely muffled and restricted from the factory. With a price tag rivaling a large down payment on a house, those who could afford a new E39 M5 back in the day were more interested in impressing their power lunch buddies with the M badge rather than with the rumbling performance notes the S62 could belt out. So in the name of sales numbers BMW, like any other manufacturer, put a muzzle on the ol’ girl leaving the performance enthusiast longing for more. But seriously though, what’s the point of having a 400hp engine if you can’t hear and enjoy it?!

Project Tundra: Getting More Grip with an Auburn Gear HP Limited Slip Differential

by Mike Kojima

Supercharging Project Tundra is one of the best things we have ever done to any project vehicle in the MotoIQ fleet.  The TRD supercharger has proven to be totally reliable in thousands of miles from towing up hill in blazing heat to driving all over the place.  It has also proven to be economical as our normal driving gas mileage has not changed at all.  If anything the large amounts of power have had only one negative effect on the truck, no traction.  To help deal with this we obtained the only limited slip diff on the market for late model Tundra's, the Auburn Gear HP Limited Slip Differential.

Project Land Speed Racer 240SX: Chassis Prep and Roll Cage Fabrication

By Chuck Johnson
 
Remember when Project Land Speed Racer 240SX first came into the hands of Chuck Johnson? In this Flashback Friday see where the record breaking first got started...  The beginning of any good sedan type racecar build almost always starts with ruining a perfectly decent streetcar. In the case of Project Land Speed Racer 240SX though, I'm not sure if we are really ruining a perfectly good streetcar. Honestly, from the looks of things, it must have been owned by a series of wannabe dorifto hacks before falling into my hands.

The rumble of a  Corvette’s big V8, supercharged, with cams is enough to shake the foundation of nearby buildings ... Walking to the shop door we were greeted with a beautiful, glistening black Chevrolet Chevelle SS.  And then you looked up and there was a 64 Corvette, the 69 Prostreet Camaro, a 2013 Camaro ZL1, a 2012 Corvette Z06, … and I could not count them all in that first few minutes.

BPG's BNR32 Skyline GT-R Time Attack Special

by Mike Kojima

Some of the cars at Australia's World Time Attack or WTAC for short are so amazing and so exotic that for most of us, we can just look and drool.  We were looking at cars to feature and we wanted to show what could be done for a moderate amount of cash by regular people.  Clean solid work by smart people but nothing that needed open wheel or prototype levels of engineering and fabrication skill.  In short, something that most of us or a good local shop could build with a regular person reachable budget.
