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

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!

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.

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.

The CSF Radiator Challenge!  CSF vs Masiv

by Mike Kojima and Khiem Dinh

During the summer CSF radiator launched a bold ad campaign with MotoIQ: the CSF Summer Challenge.  CSF boldly challenged the entire radiator industry to s shootout to see who makes the most effective radiator with us conducting the test.  CSF's only rule was that a radiator for the challenge had to be an off the shelf part built for a given car available to the general public, not a one off bespoke radiator designed just for the test.

Keep It Simple - Go Tuning's Spoon Sports Civic

by Mike Kojima

What's the best thing to do to re launch a performance brand in the USA?  Go racing. That is exactly what Go Tuning, the official North American distributor of Spoon Sports parts has done in the world of Time Attack in a big way.  In practice for the last Super Lap Battle, Dai Yoshihara, previous Formula D and MPTCC Champ peddled Go Tuning's Spoon Sport Civic to a blistering 1:46.3 second lap time around Buttonwillow's famed configuration 13 CW. This was faster than Chris Rado's long standing FWD Unlimited lap record in the high tech 1300hp F-Wing Scion TC, a record we assumed would be out of reach for a long, long time.

ARK Design Team America BNR32 GT-R Update

by Mike Kojima and Eric Hsu

The Team America crew has been busy and the car has really come together in the past couple of weeks.  The goal is to be able to have the car dyno tuned and track session tested before it has to go into a shipping container and hopefully end up in Australia this time (if you have been following our story, two years ago, instead of going to WTAC, the car ended up in China for a few months due to the freight forwarder making a huge mistake).

Eric Hsu and Gary Castillo have been working around the clock to get the car done with everyone else on the team pitching in on the weekends. The major fabrication is nearly complete and the engine has been started and run.  What's left is to finish up the top secret Andrew Brilliant designed aero package, do the final installation of the wire harness and to clean up and work on the cosmetics of the car like the Team America inspired wrap.

The Fabulous Flog: A Look Inside Dai Yoshihara's Falken Tire Subaru BRZ

by Mike Kojima

What is the Flog?  It is the nickname that the Falken team has given their BRZ drift car.  Driver Dai Yoshihara, commented when he first saw the completed car that it looked like a frog but with his Japanese accent it came out Flog and no one knew what he was talking about.  Dai had to pantomime a sitting frog and say riibit, riibit before anyone could understand that he meant Frog. 

The Falken Tire Subaru BRZ has been featured by a few other media outlets in the recent past but not like this.  Let us take you beyond the pretty pictures for a look inside the car which has been one of the most anticipated builds of a drift car to date.   One of the best looking cars on the Formula Drift circuit, the BRZ was built on a compressed time schedule by SPD Motorsports, the same folks who built Dai's iconic Discount Tire/Falken Nissan S13.

Project SEMA Scion Tuner Challenge FR-S, Getting More Power with a Ganador Exhaust

by Mike Kojima

Our first step in extracting more power from our FR-S's FA20 motor was to add an Unorthodox racing crank pulley which went pretty well.  Now we are going to take another baby step along the path of bolt on modifications by testing out a Ganador Exhaust system from Japan.
