Sneak Peek: Global Time Attack Cars Round 1

by Khiem Dinh

The first round of Global Time Attack 2017 was held at Streets of Willow as part of the Honeywell Garrett (formerly Air Research, Allied Signal, Garrett, Turbo by Garrett, Garrett by Honeywell, and maybe a couple other names I’m forgetting) Boost Fest. The thing we like about the cars and drivers at GTA is it’s still all very grassroots. Not many people with crazy budgets, a lot of homebrew economic performance enhancers, you know, stuff your average car nut can relate to in their own garage. 


 

Project E46 M3: Part 17 – The preferred exhaust setup and more AEM tuning by MKC

by Pablo Mazlumian

Life would be a lot easier if we'd stayed with the stock headers, but when we tested our VAC headers in Part 3, the increase in power was too much to let go. Since then, we've tried different header-back systems but they either were too loud, droned at low RPM, or didn't fit all too well. Today, however, we think we've found something that works great and doesn't break the bank. Dynos graphs and video clips inside!


 

A Ride with VCMC AutoCross!

by Frank Ewald

Like most of you, everyone here at MotoIQ loves automobiles and motorsports have obviously been an interest for years. Taking our cars out for a track day are an absolute highlight. Time Attack. ChumpCar World Series and ChumpCar Canada. Simply attending races of various levels over the years and even being privileged enough to photograph some of these events. However, unlike some of the enthusiasts at MotoIQ who have participated in everything, this writer has never attended an AutoCross event.  Anywhere. Not even as a spectator! So when VCMC provided an invitation to join in their Autocross Warm-Up, signing up was not a question.


 

Grassroots Drifting: Tennessee Based & Battle Tested

by Taylor Haney

Grassroots drifting or automotive racing in itself already creates a sense of camaraderie through sportsmanship and love for the sport. If you add in being a military veteran on top of that, you create a strong melting pot that resembles more of a family than a team. The Clarksville, Tennessee-based drift organization Battle Tested Motorsports did just that with 15 out of 16 members being military veterans, active duty or reserve.


 

Project S550 Part 3: Looking Better with Wide Project6gr Seven Wheels, Cervinis Ram Air Hood, AirDesign Front Fascia & More!

by Nathan Brummer

In our last update, we focused on improving the stock handling of Project S550. While we still have some suspension work to do (and we have some big plans in mind), we’re going to pause on that while we turn our attention to the car’s appearance. The 2015 Mustang has become extremely popular and they look great right out of the box but, given that popularity, we need to do something to make this project stand out from every other Mustang on the street. We’re not looking to do anything extreme or over the top, so we’ll concentrate on making subtle changes that accentuate Ford’s already stellar design.


 

Project Lexus SC300 Road Racer: Part 9 - Begin Rewiring at the... Back?

by Erik Jacobs

After over a year of slow and methodical removal, preparation, and planning, it is finally time. We held our noses and closed our eyes and clicked the button to place an order with MilSpecWiring. Dozens of connectors, hundreds of feet of wire, heat shrink tubing, buttons, pins, tools, and other supplies were finally on their way. And on the day they arrived, the panic truly set in. We actually had to finally build everything.

Subaru Clutch Forks Cracking Under Pressure?  Say It Isn’t So!

by Eric Hazen

Subarus have roamed the streets, tracks, and dirt for decades, with hundreds of thousands of upgrades available for nearly every aspect of these beloved cars.  Yet, one crucial part seemed to be passed over- the clutch fork! The clutch fork is Subaru’s Achilles heel. The clutch fork’s job is simple - disengage the clutch when you want to change gears. However, the stock part is prone to breakage and premature wearing of the pivot, especially when a performance clutch with higher clamping forces is used. 


 

TESTED: Continental Tire ExtremeContact Sport

by Billy Johnson

“Same level dry performance as a Michelin Pilot Super Sport”. That is a HUGE statement by Continental when the PSS is hands down the segment leading benchmark.  Continental is extremely proud of their brand new ExtremeContact™ Sport tire that was just released earlier this month as a replacement for their ExtremeContact™ DW tire.  We logged nearly a thousand miles on the new Sport in both the wet and dry, and put it up against the outgoing DW in a back to back test at Palm Beach International Raceway to see if it lives up to Continental’s claims.


 

Project Viper GTS: Part 9 – RareFab/Roe Racing Oil Pan Baffle Kit

by Billy Johnson

Due to the high capabilities of the Viper, a huge strain is put on the factory oiling system on road courses and at the strip.  This can cause oil starvation and a spun rod bearing.  Using modern rubber can increase this risk, especially for 1996-1999 Gen-2 Vipers which have arguably the worst oil pan of any generation of Viper.  To combat this problem, we upgrade to the larger 10-quart oil pan and windage tray from the 2000-2002 Vipers and install RareFab/Roe Racing’s race-proven Oil Pan Baffle Kit.

Purple in Motion - Jackson Racing Supercharged Scion FR-S

by Alvin Miles Jr.

Car enthusiasts in this generation are always after the newest and hottest automobiles being released. When it came down to a sports car, Toyota was definitely behind in that department. Akio Toyoda, (the President of Toyota and grandson of the founder), wanted that feeling to come alive again. In spring 2012, the Scion FR-S (front engine rear-wheel-drive ‘sport’) was launched. Inspired by the mid 80’s Toyota Corolla, also known as AE86 and known to be any drifter’s eye candy, the FR-S was set to be agile, light, and most of all, affordable. That was the same feeling that Phil Chien felt with his AE86 that he once had. Once the GT86 (Toyota’s formidable version)/FR-S was released, he knew that he had to have one.


 

Turbo Tech: Internal vs. External Wastegates

Every production street car comes with internally wastegated turbochargers. There are many reasons for this, but what is given up in torque and power compared to an external wastegate configuration which dumps the wastegate flow separately from the turbine exhaust flow? Luckily for us, Bren Tuning performed some testing on a 2015 Subaru WRX using exhaust manifolds from Killer B Motorsport configured for both internal and external wastegate configurations.
