Nerd’s Eye View: LA Auto Show – Go-Fast Vehicles

by Khiem Dinh

The motorsport scene has undergone large technical changes over the last half decade with the implementation of high-efficiency technologies. Some of the technology has shown up in concept cars. Some of the technology in road going cars have been eliminated from the race car version. Then there’s just good ole big displacement with forced induction on top. There was even a bit for the off-road guys.

LA Auto Show 2017: Nerd’s Eye View – BMW

by Khiem Dinh

So, what was going on in the BMW booth? A lot of electric stuff. A lot of ‘M’ stuff. A lot of carbon fiber. It seems you can get a M Performance version of just about any model BMW now- much like how you can get an AMG Mercedes everything. What do you get for the extra Benjamins dished out for the M Performance packages? Fancy carbon fiber exhaust temps with the M logo etched into the tips for one.

480WHP Honeywell Garrett Powered F20C: Devin Giles' Time Attack S2000

by Khiem Dinh

It all starts the same way. “I want to go auto-crossing!” you say. So, you start browsing the interwebs and research the S2000. You start auto-crossing and start modding and moving through the classes. Then, you do a track day. Then, you mod the car some more. Then, you do time attack. Then, you end up with a highly built race car like Devin Giles- owner and driver of this fast S2000. It’s a familiar path; there’s probably a support group for it out there.

LA Auto Show 2017: Nerd’s Eye View – Porsche

by Khiem Dinh

I was short on time this year at the LA Auto Show, so I had to do a bit of a blitzkrieg. The one booth I have to visit every year is Porsche because the cars are simply awesome. In addition to the GT2RS, Porsche was highlighting the Cayman and Boxster GTS siblings, 911 Carrera T, and a few 4-door sedans. I got sucked into the GT2RS and almost completely ignored all the other cars.

Nerd-O-Scope: Honeywell Garrett’s G-Series Turbochargers

by Khiem Dinh

The new Honeywell Garrett G-Series turbo line is the most exciting product launch since the infamous Disco Potato. Everyone knows the GT-Series turbos were getting very long in the tooth. The GTX launch was an upgrade with updated compressor aero and new families of v-band, T3 divided, and v-band divided turbine housings. The GTX Gen2 launch was a further improvement in compressor flow along with new compressor housing castings. But overall, the foundation of the turbos had stayed the same for two decades. Enter the G-Series which is a clean sheet design to address and upgrade every aspect of the GT/GTX series turbos. This is a true motorsports grade turbo for the masses.

Sneak Peek: Porsche Experience Center, Los Angeles

by Khiem Dinh

The Porsche Experience Center in Los Angeles is just a mile down from my work office, so a few of us go there for lunch every couple weeks. There’s always some type of awesome race machinery in the lobby, and the cars are changed out every so often. There were some particularly tasty cars on this trip, so I whipped out the camera for some quickie snaps.

Nerd Alert! Mazda’s Skyactiv-X Engine

by Khiem Dinh

As we are sure many of you have heard, the little car company that could, Mazda, has announced their Skyactiv-X engine with the technology to run Homogeneous Charge Compression Ignition (HCCI). Two major challenges to make HCCI work: timing of the combustion and smooth transition between HCCI and regular spark ignition. The HCCI combustion process has been researched for decades, but the technology to bring an engine using HCCI to market has been elusive until now.

So how did Mazda do it? We are going to take a few guesses, but as with most technologies, it didn’t happen overnight. In fact, we would say Mazda’s first big step was a few decades ago. The final piece of the puzzle is a technology Mazda has called Spark Controlled Compression Ignition (SPCCI), and we will exclusively get into how that ties into making HCCI work.

Italy Road Trip! Cruising in a Fiat 500L 

by Khiem Dinh

So, I did a thing where I said some words, exchanged some rings, and eventually hopped on a plane to Italy! The wife and I probably could have taken trains to get around, but we’re MIQ, we drive. And, when you’re in Italy, you drive a Fiat if you’re a person of normal means. Plus, the Ferrari 488 didn’t fit our luggage. So, I’m going to fill you in a bit on the 500L and some tips and tricks for driving Italy.

Tested: Rally Ready Driving School!

by Khiem Dinh

I started watching WRC around fifteen years ago and more recently rally cross, but I had never learned the skills required to drive a car in dirt. I’ve done drag racing, auto-x, road courses, motorcycle track days, and more recently supermoto. Heck, I have even gone mud bogging and driven dune buggies, but I haven’t gone sideways in dirt. It so happens our buddy Texas Dave has his Rally Ready driving school in my favorite city of Austin, Texas.

A Tribute to Nicky Hayden: The Kentucky Kid, The Champion of Champions

by Khiem Dinh

It has been some number of days now since Nicky Hayden passed away in a cycling accident. The world of motorsports still hurts with the void left behind. The Kentucky Kid, as he was known, was special in the high profile world of top-level motorsport athletes. His character, his work ethic, his love of riding and racing, his easy-going personality, and the time he made for his family and fans is what puts Nicky a step above any other athlete in motorsports. It is said over and over Hayden was the nicest guy in motorsports. He was the commensurate professional and never spoke negatively of anyone.

Nerd’s Eye View: 2016 Kawasaki ZX-10R

by Khiem Dinh

If you’ve been following World Superbike, you know Kawasaki has been dominating. The motorcycles used in World Superbike are highly modified motorcycles you can buy from your local dealer. World Superbikes are to street bikes like FIA GT3 cars are to street cars. Yeah, the bikes are highly modified, but the fundamental base is the same unlike MotoGP bikes. MotoGP bikes are the equivalent of Formula 1 where they probably don’t even share a bolt with the street bike. Back to the point- Kawasaki bikes kick ass in World Superbike, and the ZX-10R bike you can buy kicks ass too.

Turbo Tech: Calculating Turbocharger Compressor and Turbine Performance Advantage with the New Honeywell Garrett GTX Gen2

by Khiem Dinh

In our Turbo Tech series, we have covered a lot of segments of turbocharger performance. We have looked at various aspects of compressor efficiency and performance, turbocharger mapping, and turbo sizing and matching among other things. This time around, we are going to do some more calculations on the turbine side, calculating pressure ratio and wastegate flow along with estimating power gains from the Honeywell Garrett GTX Gen2 turbos over the first generation GTX. You better get your Excel spreadsheets warmed up.

Markos’ Snail Performance WRX: Attacking Time with a Message

by Khiem Dinh

Markos Mylonas just kicked a lot of ass in his Snail Performance WRX. See how he put the hurt on his Street AWD competition and threatened the times of GT-Rs with a smart selection of bolt-on components.

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.

Turbo Tech: Internal vs. External Wastegates

by Khiem Dinh

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.

LA Auto Show 2016: Nerd’s Eye View – Cars, Engines, and Electrons

by Khiem Dinh

All of you have seen it, the change in the automotive powertrain landscape. The driving force behind the changes is the desire for mankind to not choke and die breathing air (i.e. check out the air pollution levels in China and India right now). The upside to this push for cleaner air has been more torque, more power, and better throttle response. You can thank turbos and electric motors for all that goodness.

LA Auto Show 2016: Nerd’s Eye View – Race Cars and Randoms

by Khiem Dinh

There are always a handful of race cars at the LA Auto Show. The old saying goes, “race on Sunday, sell on Monday." Motorsports are a place for auto manufacturers to test their technology too. If the technology holds up on the race track, the technology should work on the street, right? There were a couple of other race vehicles there, along with some other random things I thought were cool.

LA Auto Show 2016: Nerd’s Eye View – Ford

by Khiem Dinh

Ford has been pushing a lot of performance within their product lineup. Much of that pushing has taken the form of placing their Ecoboost technology in everything they make. However, they do have some other goodies too that don't involve turbos. For the type of guys who got pissed that Ford put a twin turbo V6 in the Ford GT, they’re really going to be pissed about what Ford did to the new Raptor.

LA Auto Show 2016: Sneak Peek – Porsche 911 RSR

by Khiem Dinh

Porsche has gone and done it now. Personally, I think Porsche should have just transitioned to the Cayman for their GT race car, but I’m no Porsche ‘purist’. And in the interest of not getting their butts kicked, apparently neither are the heads of Porsche Motorsports.

SEMA 2016: Nerd’s Eye View - Track Cars

by Khiem Dinh

There’s always some track car goodness at SEMA. Many of these vehicles are based off of street vehicles. Depending on the race series, the cars vary little from the road legal street cars with not a whole lot more than gutted interior and roll cage installed. Then there are other race cars that only share the exterior semblance to the street car with everything underneath the skin completely changed. SEMA had a bit of both along with a classic.
