The grand majority of MotoIQ readers have been to some sort of motorsports event. Whether participating in a track day or simply spectating at a pro event, we're always looking for ways to get our motorsports fix in. Until now we have always had to make a choice between being part of the action or just watching. Not anymore! The Street Driven Tour is a motorsports bash with something for every gear head. You want to watch some road racing, they've got it. You want to go on a drift ride along, they've got that. Want to play some drift-soccer, they've got that too!

You likely have your perceptions about Canada - the country north of the United States that is full of mountains, forests, and calm, happy people. So I am sure that the title Radical Canada may make you wonder. Perhaps you have read some of my other articles and realize that, on the race track, there are some pretty radical Canadians. Here, however, my focus is upon the Radical sport racer.
When we last left our Project SC300, aka “Damnit”, we had just sat the new Fuel Safe/Radium Engineering fuel cell into the trunk area in order to mark out where we would cut. We had also removed the rest of the factory stock hard fuel lines to make way for our fancy new braided stainless lines that we will assemble ourselves. Now follow along as we mount the cell in place.
Fluidampr performance dampers challenge the misconception that a viscous damper is only suitable for large, low rpm industrial and commercial diesel engines. Follow the design and development process, plus comparative testing of a new Fluidampr performance damper for the Subaru FA20 / Toyota 4U-GSE 2.0L opposed-four cylinder ‘boxer’ engine. The engine is featured in the popular 2013-present Subaru BRZ, Scion FR-S, Toyota GT86 and new 2015 Subaru WRX.
In our last update on the Blacktrax Performance S2000, nicknamed “Irene”, we covered the basic motor internals, exchanging the rubber subframe mounts with solid pieces, and the rubber suspension bushings with spherical units. We had made some body modifications in order to fit the new wheels and tires, and also for the final aero pieces, which will be covered first in this update on Irene.

This is Damnit. All of my cars have nicknames, but this one earned its name long before I ever picked it up. I could write a book about everything that’s either been wrong or has gone wrong during the previous phases of this build. That being said, this is my first “real” race car. I intend to use Damnit targeting NASA Pro Racing’s ST2 class. Super Touring is a power-to-weight class with fairly open rules. Pretty much as long as you don’t move suspension pick-up points you can do a lot of things. ST2 is limited to 8.0:1 (lbs per horsepower) which, with a ~3200lb SC300 limits me to ~400WHP. Power, engine and other info will come in subsequent articles. Today, we're prepping to install a fuel cell.

We all know when Nameless Performance has an idea on how to increase the performance further on their designs they will put into motion a plan of attack and some awesome fab work. They are pretty much the most aggressive company I have come across in my years of dealing with manufacturers across the spectrum. Improving upon their design is one thing they are allowed to do when building parts per your order. You the customer get the most current fabrication of the latest, greatest part they can make at that time.
Not so long ago we evaluated HKS's new Max ST coil over suspension system on a Honda AP2 S2000. The S2000 is a pretty decent handling car from the factory that is pretty suspension sensitive, the AP1 in particular has a lot of toe change with suspension moment and some wonky suspension can make it quite a handful.
For our next evaluation we decided to try the other HKS coilover in the lineup the Max GT damper. While the Max ST is calibrated for the serious driver being set up like a hard core street and or weekend warrior track day shock, the GT is made for a mildly performance oriented driver that wants to lower their vehicle with a decent ride and have handling that is a step up from stock but with little sacrificed in the way of ride comfort.
At Professional Awesome Racing, we take pride in thinking through problems and coming up with solutions that are as efficient and reliable as possible, all while fitting into a modest budget. We try not to do things that other people do just because “it’s always been done that way.” As you can read in our previous articles, this has lead to unique designs with our chassis/roll cage and powerplant. We like to think this same mentality translates into our fuel and computer systems and that’s the topic we’ll dive into today. So enjoy reading while sitting on your favorite throne or perhaps fire up MotoIQ at work with a finger quick to pop up a spreadsheet if the boss walks by.
As we all know, the key to making power is to create pressure in the combustion chamber - and to create that pressure at the right time. This pressure works to drive the piston down in the cylinder and cause the crankshaft to rotate. The more air/fuel mixture you can get into the combustion chamber, the greater your potential for creating more pressure, and more power.
If the engine as a whole is the heart of a car the cylinder head would be all the supporting parts that make the heart pump. Without the opening and closing of certain valves of the heart you can’t get blood to flow into the atriums and out the ventricles. Just like the heart, a cylinder head has multiple valves that need to open and close at specific times to get air in to and exhaust out of the combustion chambers to keep the engine pumping.
There is nothing like seeing a race car in action. Even more, there is nothing like watching a race car move from a bare shell into a Global Time Attack Unlimited Front Wheel Drive class winning race car. William and Noreen Au-Yeung welcomed me into their store, Point Zero Audio and PZ Tuning, then opened the shop doors so that I could follow along on the build of this Honda Civic.
