When we first heard about the lineup of products that Krona Performance had to offer for our 9-5 race car, we knew we had to get in touch. A few months later, the drtuned Racing and Krona Performance partnership was thriving, and our build was well on its way to reaching this year’s power goals. More than just horsepower and reliability, now the relationship with drtuned, Krona Performance, and eEuro has netted a new result. Krona Performance parts are now available on eEuroparts.com! [shop for your car] Introducing Krona Performance Located in Charlestown West Virginia, Krona Performance produces hand-crafted performance parts using American sourced T304 Stainless Steel. Every Krona product comes backed with a lifetime warranty, so your shiny new parts will likely outlast your car! So what’s all the hype about? Any brand of performance parts is just as good as the other right? Wrong! Let’s take a look
The Short History of Saab Trionic When it comes to engine management, there are a number of ways to cook the goose. When the IC engine was first produced, several huge hurdles had to be overcome just to get it running right. The science behind using venturi currents to feed fuel based on airflow (how a carburetor works) was a huge breakthrough, and in many cases is still used today as a simple and effective device to control how an engine works. As time progressed, we realized that the more control we had, the better our engines would run. The biggest hurdle to overcome was how to provide the best performance, without allowing the air/fuel mixture from pre-detonating, also known as knocking or pinging. A big moment happened when knock sensors began to be installed on engines. However far from sentient, this allowed the car to know when the timing is
After all of the critical measurements needed on the crankshaft were done, it was time to put it back into its home with some fresh bearings to continue the engine build. Since there was no noticeable wear on the crankshaft, standard-size replacement bearings were used along with an appropriate amount of assembly lube. The torque specifications for all of the main crankcase bolts are torque-to-angle, which requires you to set the bolt up with a relatively low torque setting first, then finish with a final turned angle using an angle meter. Digital angle torque wrenches are great tools, but can be fairly expensive for the home mechanic. I’ve been using these manual angle gauges and although they take a little longer to set up on each bolt, I’m happy with the results and no batteries required. After using the proper torque sequence, the crank is in, spins nicely and we’re
We go to a lot of shows a year. The slammed look is popular, most presumably because it makes a car look more performance oriented. I mean, in general full blown race cars are very close to the ground. That keeps a lower center of gravity and ensures the least amount of airflow is allowed underneath (thus reducing lift). The interesting part about stancing out a car is that, while it might actually handle better on a race track if you know what you are doing and your alignment is good, on public streets the utility of this is nearly non-existent, and even extremely inconvenient depending on your environment. I’ve noticed an interesting trend in European car shows over the years that people are looking for something different. This almost always involves a sawzall and a MIG welder, we’ve all see Monster Garage. Chopped Euros, a Ute if you will.
After a very cold New England snap, a January thaw has reminded me that the racing season is fast approaching and we better get back into the shop! The engine block came back , hot-tanked and bored for our forged Wiseco pistons. These pistons have thicker top ringlands and the forging process gives superior strength and durability over the hypereutectic factory ones. With the all the bottom end saab performance parts here, let the build begin. First thing I want to cover is the current development of parts in our balance shaft delete kit, in progress. Before I even get into sizing up the new bearings and assembling the crank, I wanted to take a look at the balance shaft and engine timing system. But, we probably should talk a little about the purpose of balance shafts first. Balance shafts are weighted shafts that run off the crankshaft in order
