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.


Diagnosing the Screech on a Silverado LB7 Diesel Engine

by Karla Pestotnik

Any car can eventually get a pesky squeak coming from the drive belt area under the hood. For many 1999-2007 General Motors V8s, this has become an infamous issue. However, this common issue is often more than just a belt change; it can be a little bit more complicated. In our case with the LB7 diesel Silverado, it was multiple sources contributing to some head-scratching pondering. Since this is the dedicated tow vehicle for the Karla Pestotnik Racing team and a big event is coming soon, we needed to get to work to diagnose and fix the tow rig. 


AEM AQ1 - Using Data to Develop a Car

by Ramitha Edirisinghe

The goal of this series of write-ups is to show how powerful data logging can be for race teams, and how AEM’s line of data acquisition products gives access to this to the grassroots racer at an affordable price point. In the first section we went over the various features of the AEM AQ1 and what they meant. In this section, we’ll go over how the Jager Racing Team uses data acquisition to improve both Mark’s driving and the development of the car. In Section 3 we’ll go over lessons we learned while using the AEM AQ1, and how we installed the system on our car.


Building a NASA NP01 Prototype the Right Way with Stoptech! Part 3

by Mike Kojima

We have been following the Stoptech's team build of their NP01 in the MotoIQ Megashop for the past quarter. Although we stretched out the coverage for editorial scheduling, the actual build took about a month. Although the NP01 can be built relatively quickly as a multi-weekend project, we are showing the right way that Stoptech is going about it to build a first class, reliable NP01 that is going to win some races.  


Tested! NOCO Genius Boost GB40-Emergency Jump Starter

by Mike Kojima

Having a dead battery really sucks. Not only can it leave you stranded, but you are also dependent on finding a good samaritan that is willing to give you a jump start. Not only is this bad because you are depending on luck, but it also exposes you to danger as you ask perfect strangers for help.


Project Mazdaspeed3: Building a Stock Class Cone Killer- Introduction and Installing Koni Shocks

by David Zipf

Autocrossing is a ton of fun. It’s super cheap, you can take almost any car under the sun, it’s fun, and the crowd is very friendly. Within 2 weeks of laying claim to a 2008 Mazdaspeed3, we were dodging cones. The Speed3 is a great Street Class car, with lots of grip, tons of torque, and low gearing to take advantage of that torquey, turbocharged Mazda MZR engine. In other words, a Mazdaspeed3 (or a Ford Focus ST, which is built on the same platform), makes for a great cone killer, with just a few simple modifications.  


PRI 2016 Street Outlaws Edition: Part 1 – The Nitrous and Supercharged!

by Pablo Mazlumian

PRI 2016 was full of famous cars from the Street Outlaws show on the Discovery channel, and we took the opportunity to give you a closer look at several of them. This two-part series is full of info on these stupid-fast cars and crazy drivers you won't find on the show, and today we start with the nitrous and supercharged!


Making the Ford F-150 Ecoboost Drive and Tow Smoother with Eibach Shocks

by Rathyna Gomer

My dad's Ford F-150 Ecoboost is something I frequently drive, usually to pick up car parts and to tow one of the racecars out to the track. Similar to many folks who also own a racecar, the majority of my focus and money has gone into the racecar, not the tow rig. In actuality, I'm spending hundreds of more hours in the truck picking up parts for the car and towing the car to the track, than actually driving on the track. 


Building the FR-S FA20 engine with Stay Crushing, Assembling the Engine!

by Mike Kojima

In our previous installments of the Stay Crushing FR-S engine build, we have been accumulating the parts to build the supercharged FA20 engine. Now we have everything, and it's time to put it all together!


Project 5.0 Mustang (The White One) Building the 302 Coyote Engine!

by Mike Kojima

We were eager to get into our motor and install the Ford Motorsports parts that would basically enable us to rev to over 8000 rpm reliably and breathe better on top. The parts we accumulated would bring us to a spec about the same as the Ford Motorsports Aluminator performance crate engine and a little bit more than the Drag Racing Cobra Jet NA engine. 


AEM AQ1 - Affordable Data Logging and More!

by Ramitha Edirisinghe

While on-board data logging has been used by professional race teams for decades, it has been simply too expensive for the average grassroots racer to afford. Recently, however, AEM came out with an awesome entry level data logging unit aimed at the grassroots racer: the AQ1. With an MSRP of $395, the AQ1 packs a lot of great features at a very reasonable price.


Building the Naturally Aspirated Honda K Engine Part 3, Assembling the Engine

by Mike Kojima

In the previous two installments of our engine build, you were able to take a look at the parts we will be using to build the bottom end and the cylinder head of our Ariel Atom. Notably, we went with a Dailey Engineering dry-sump system, since the Atom has a lot of aero-enhanced grip, and we want to avoid oil starvation.


Velox Motorsports - FR-S / BRZ Rear Diffuser Development 

by Erik Hazen

The people at Velox Motorsports are our kind of gearheads- engineers who believe aftermarket components should be well-engineered, functional, and shouldn't just look good enough for mass production. With the popularity of the FR-S and BRZ chassis, there has been no shortage of so-called "aerodynamic" products, that are mostly cosmetic and don't have any engineering behind them.

The lack of in-depth engineering within the aero parts industry triggered Velox Motorsports to design their own rear diffuser. They knew that they could improve on what was on the market currently. They wanted to maximize performance, leverage aesthetics, add to their already existing front splitter, and offer additional components not offered to the market previously.


KW Automotive USA-Plant Tour

by Mike Kojima

If you have been a long time MotoIQ reader, then you have probably read about our tour of performance suspension giant KW Automotive's production and R&D facilities in Germany. KW has had a North American operation for some years now, but has recently expanded their facilities from their first location in Sanger California to a new location in Clovis California. 

KW's old Sanger facility was mostly dedicated to warehousing and service of their suspension stuff. The new location is being put together to have additional flooring space for R&D, engineering and Manufacturing.  This includes all of the KW Automotive brands consisting of ST Suspensions, Belltech, LSD Doors and of course, KW Suspension.
