    Silver Crown Writer

    I've been sim racing since 2011 when I joined iRacing. I've jumped to many different sims, including rFactor, Richard Burns Rally, and the famous NASCAR Racing 2003. I picked up a copy of NR2003 with my birthday money when I was only 9, but was limited to a keyboard and a controller. After reciving a G25 for Christmas in '11, I've loved sim racing and the community iRacing has. I hope to end up writing for a car magazine or website in the near future, and intend on attending university to accomplish that.
    Aside from my career in sim racing and the real world, I hope to have my own small, yet functional race team soon with the purchace of a go kart. Since I'm currently residing in Maryland, I don't have a wide range of racing to choose from. My only options on a small budget are drag racing or kart racing. After the completion of my senior year in high school next year, I hope that inRacing News and other affiliates will help my dreams of writing for Road & Track become a reality!

Okayama Star Mazda 6

Okayama International Circuit played  host to the opening week of the 2014 S4 iRacing Star Mazda Championship, with over 1000 iRacers taking the green flag! Every online race this week – bar two -had a couple of splits or more, indicating it was going to be a closely-fought battle for the advantage in the championship on the opening week of the season. The Friday 19:45 GMT race had the highest SOF (strength of field) of the week, one amounting to 3188 . The grid was incredibly competitive, with even a couple of Pro and Pro/WC drivers turning-out for the race in the forms of Riku Alatalo and  Joonas Nukarinen. But Michal Smidl (Central-Eastern Europe) took the pole, with Mike McKinney (Illinois) beginning in second  and Jerome Haag (France) rounding-out the [...]

The Kitchen Sink: Homestead – Not a Typical 1.5 Miler

by Ray Kingsbury on September 4th, 2014

TheKitchenSinkDW12

Previous: 1 | 2 | 3 | 4 Homestead is one of those tracks that is so similar to yet so different from other tracks on the schedule. At 1.5 miles, Homestead is the same length as far too many high banked speedways; however, the differences between Homestead and other 1.5 mile circuits are easily seen as a driver. A typical 1.5 mile setup for the Dallara DW12 IndyCar will not work here: You will find a lack of rear grip and, at the same time, a lack of front end grip. It may be a good idea to load-up a base 1.5 mile set for starters; the chassis, gear ratios, and dampers should be a good starting point. The biggest thing you are going to want to change is [...]

The Kitchen Sink: Finding a Little Bit of Speed at Motegi

by Raymond Kingsbury on August 19th, 2014

TheKitchenSinkDW12

Previous: 1 | 2 | 3 Twin Ring Motegi’s Oval course is one of the trickiest on iRacing. At first glance one would think that it is a very easy course. The racing surface is very wide and the pavement very smooth; however there is something about the Japanese asphalt that makes this track very difficult and lacking a lot of grip. With the superspeedway aero package being on the Dallara DW12 for Motegi, most drivers are having to lift on the fixed set through Turn One and Two and brake into Three and Four. There are some things that a driver can do to his or her car to significantly improve the handling here and find some time. For one, you are going to want a lot of downforce [...]

Road Warriors at Mid-Ohio

Labati leads the field into the Keyhole.

The iRacing Road Warrior Series traveled to the challenging Mid-Ohio Sports Car Course in Lexington, Ohio for Round 10. This battle saw the Road Warriors take on the course in the Dallara DW-12 for a 50 lap sprint to the checkers. The high downforce car was on edge the whole way around Mid-Ohio’s off camber sweepers, and crooked crests. The weekend kicked off at 1:00 GMT Saturday with one large split totaling 37 cars. This made for an interesting race, as there were many different skill sets in the same race. Between aggressive, fast-paced drivers and slower yet more calculated drivers this race was anyone’s to call. The message to heed in this race?  Discretion is the better part of valor. Rob Kodey was victorious after leading only six laps [...]

NASCAR iRacing Series Open Garage: Indianapolis Motor Speedway

by Don Scott on July 22nd, 2014

188
The Brickyard poses special set-up challenges for NASCAR iRacing Series competitors.

This just in: Indianapolis Motor Speedway is a 2.5 mile oval. Long straights and four sharp turns provide the qualities of the high speed speedways with the challenge of setting-up the car for braking and corner rotation which will be key here as corner exit is going to play heavily on the cars’ acceleration going into the straights. Beginning with the stock setup you will find the rear of the car is tight on entry and loose beyond control from middle off. Most of this can be attributed to the weight distribution. In this case they have set the weight all the way back. What this does to the car is pull the center of gravity back like a ball on a pendulum. When the weight is shifted in the [...]

NASCAR iRacing Series Open Garage: Kentucky Speedway

by Don Scott on June 27th, 2014

NASCAR iRacing Series Open Garage: Kentucky Speedway

Kentucky Speedway, for some, is one of the most difficult of the 1.5 mile speedways. You would think with its steep banks and wide front straight it would be one of everybody’s favorites; however the bumpy surface and limited preferred driving grooves can be deceiving. There are points where the rough surface, combined with windy conditions and track temperature, can cause the car to just cut loose for no apparent reason . . . or just bog down, reducing critical momentum. Many have commented that the base setup is loose to the point of being nearly uncontrollable. Newer drivers have found themselves spinning through the front stretch. Further inspection of the base setup shows an overly aggressive camber setting in the left front and a conservative right front camber also [...]

The Kitchen Sink: Dallara DW12 – Indianapolis Motor Speedway

sim racing

This week I had the unique pleasure and opportunity of sitting down with iRacing.com’s Eric Hudec.  First, let me just say, Eric is one of the most accommodating people I have ever interviewed. He took time out of his work day to sit down with me for an hour and a half and describe every nuance between the “old” Dallara IR03/05 and the Dallara DW12. So, let me take this opportunity to say thank you Eric. For  your time and for the amazing work you do  for this community. Without Eric, this piece simply wouldn’t have been possible. Many of the things I thought I understood were misconceived notions. Some things were right, but certainly some things were wrong. First of all, let me just say that the setups included [...]

The Kitchen Sink: Getting Started with AutoClub

by Ray Kingsbury on April 25th, 2014

Kitchen Sink

Auto Club Speedway, the latest oval to be added to the simulation, offered iRacing.com IndyCar Series a breath of fresh air last season as it ushered-in some of the highest strengths of field we had ever seen. A lot of teams prepared before the season started so they could be competitive at the track. I know my team had a setup together before the clocks turned for the new season to start. However, the weather conditions sent us back to the drawing board. Depending which corner the wind most affects — and keeping in mind the asymmetry of Auto Club — one must determine the proper route to go with their setup. Turns One and Two are more representative of what we would find at an intermediate speedway, Homestead maybe. [...]

The Kitchen Sink: Setting Up Iowa

by Ray Kingsbury on April 7th, 2014

TheKitchenSink

Previously: Article 1, Article 2 Iowa is one of the most unique tracks on the IndyCar circuit. It is essentially a replica of Richmond with higher banks and in general is a bit longer. As the fastest short track out there, Iowa provides some crazy sim-racing. For the past couple seasons the track was flat-out all the way around, unless you cooked the right front tire. With this weather and the fact that it is during the day, the car gets a massive push in Turns Three and Four. If you have a solid Richmond base set, that is a great starting point, just adjust your cambers and gears. For the purpose of this article however, we will start with the Iowa Fixed set with 5 rear ARB arm and [...]

The Kitchen Sink: Setting Up Michigan

March 27th, 2014

TheKitchenSink

Michigan is one of my favorite tracks on the Indy Car schedule, second only to Iowa Speedway. Both tracks require different driving styles, and both tracks are next on the IndyCar schedule. So, expect another article next week. I decided to skip Kentucky because the eight page document that I wrote introducing you to Homestead, should’ve been enough to give you a set for Kentucky. Actually, it is exactly what I used at Kentucky with minimal adjustments. Michigan is different from both of these tracks, but if you had a set that you really liked from Kentucky and Homestead, I would say throw it on and try it at Michigan with some tweaks. The base suspension settings are close enough that it could work. For starters though, let’s use the [...]

The Kitchen Sink: IndyCar Setup Introduction

Ray 5

Last night while running some go karts at On Track Karting with a friend who was back on spring break and my brother, I had a bit of a revelation. Even on these rental karts, which had no setup components or anything, there were things you as a driver could change to make it handle better. My friend did not really understand much of this at all, he doesn’t sim race, but he also isn’t a complete idiot when it comes to racing. We did two races back to back for a start. In the first one I went out without changing anything, but as I came into the pits to prepare for race two I had them move the seat forward. Why? To fix the balance of the car. [...]

With the 2014 NASCAR iRacing Series set to get underway later this week, iRacingNews is introducing the first in a regular series of articles by Eric Isenbeck designed to help those many iRacers who are not part of multi-driver teams develop set-ups for the Gen 6 Chevy SSs and Ford Fusions they’ll be racing in the series.  While iRacingNews makes no guarantees that you’ll morph from mortal to alien by following the the ideas, concepts and opinions in the articles, we do hope A Team of One will help illuminate some of the art and science behind the black art of chassis set-up – Ed Set-up building is often considered one of the hardest feats to master in motorsports. There are about 50 different variables in iRacing that can be [...]

Brandt Wins Spa as IndyCar Title Chase Tightens

Garese leads a pack of IndyCar Dallara through daunting Eau Rouge.

The iRacing.com IZOD IndyCar Road Series made a visit to one auto racing’s most historic tracks – Belgium’s Circuit de Spa Francorchamps — for Week Eight in the series one and only appearance on European soil this season.  102 drivers put-in laps during the week with 10 different drivers taking victory on the 4.35 mile course. iRacers take to this 19 turn course and pass through one of auto racing’s most famous sections named “Eau Rouge.”  The track’s layout has changed a lot in its 90+ years of existence, but Eau Rouge has remained a constant.  This downhill-uphill left-right combination dares drivers to take it flat-out, but be just slightly off your line and the circuit will bite you.  Drivers can choose to take it easy, but those who don’t [...]

Ottinger Survives Schoenburg’s Charge, Wins Charlotte

by Jason Lofing on May 30th, 2012

Ottinger had the pace and the reliability at Charlotte to take his second win of the season.

Nick Ottinger scored his second win of the 2012 NASCAR iRacing.com World Championship Series at Charlotte Motor Speedway, holding hard-charging polesitter Brian Schoenburg at bay on a late restart before the latter’s motor expired with four laps remaining. After starting eighth, Ottinger ran at or near the front throughout the online race and took advantage of misfortunes that befell Ray Alfalla and Steve Sheehan to move into contention as the laps wound-down. After grabbing the lead from Byron Daley with 29 laps remaining, Ottinger took the checkered flag ahead of Alfalla, Kevin King, Patrick Baldwin and Daley, hoisting himself into the middle of the championship picture in the bargain. The last quarter of the 200 lap, 300 mile race was packed with action. The final scheduled pit stop on Lap [...]

The Lotus 79 is more fun to drive than ever.

iRacing’s Eric Hudec recently provided the Lotus 79 community with a superb example of community co-operation in working through a series of comparatively simple, but much requested, changes to this challenging Class B car. Led by Classic Lotus Grand Prix Series/community leader, Frank Herfjord, the Lotus 79 community used a forum thread started by Hudec to discuss changes they felt were fairly simple to implement but important to improving the realism and enjoyment of the car. Within a week of the discussion, Hudec had worked through the requests and created a patch which he successfully implemented on Monday night, allowing the community time to get used to the revisions before Week 2 commenced. The revisions included changes to the Lotus 79′s fuel economy, the increments for fueling the car, increased [...]

A Weekend to Forget

A Weekend to Forget

This past weekend saw the S.A. Shelby Can-Am championship head to the fastest track in South Africa, the East London Grand Prix circuit. After securing a hard-fought win at the last round at Zwartkops, debuting for new sponsor Hollard Insurance, reigning champion Darryn Lobb was aiming for nothing less than the top step of the podium. After struggling for pace at the previous round, the Kyalami based resident, elected to run the car of Sean Grieve who was unable to make the event. It was a car with which Lobb had previously won both events at Zwartkops in 2010. New body work, and a slightly modified design, meant that the Hollard-backed car was not only going to be fast, but also eye-catching. In summary though, East London proved that it’s [...]

IndyCar Aero Primer

IndyCar Aero Primer

Most of new (as well as many experienced) IndyCar drivers feel a bit overwhelmed when they look at the aerodynamic setup options the Dallara IndyCar offers them. However, this subject is not as daunting as you might think. Since most sim racers lack a bachelor’s degree in physics but do know how to race the car, iRacing has developed the aero calculator just for you. You can find this extremely useful tool in the garage on the “tires /aero” screen (see screenshot below). So what does the aero calculator do? This tool calculates the amount of drag your current aero settings generate in relation to the amount of downforce they produce. For example: A high rear wing wicker setting combined with a low rear wing angle can generate the same [...]

iRacing’s Corvette: Good Enough is Not Good Enough

iRacing’s Corvette: Good Enough is Not Good Enough

We’ve gotten approval to build the Pratt & Miller Corvette C6.R GT1 car!  SWEEEEET!  OK, what’s first?  Hmmmm. Dyno sheets.  That’s the most important thing, right?  That beautiful sounding motor, deep and rumbling, with earth-moving torque and acceleration.  Now that sounds like fun! Getting the power to the ground is next, so what gearbox does it use?  What are the various gear ratios?  How many options of gear ratio, and what’s the layout and the inertia of all the components?  Xtrac builds the box, and my friends at Xtrac USA have been exceptionally helpful with data for component inertias in the past, maybe they’ll provide me with additional values… And it’s got wings, well, one, and it’s HUGE.  That must make a TON of downforce.  But then there’s none on [...]

Drag’n Slayer

Drag’n Slayer

I was working on some acceleration tests at Indianapolis with various cars to determine their power curves and stumbled upon an interesting idea. I figured I could estimate the drag coefficient from the cars by capturing some telemetry data. I wanted to remove the aero drag and rolling resistance forces from the data in order to grasp the values of the power to the wheels, and to do that the best approach is to collect speed data as the car coasts down from a high speed. But I realized I could also extract the aero drag values for each car tested. When you plot the deceleration rate (change in speed/change in time) and curve-fit using Excel, you can estimate the aero drag and rolling resistance force since: F = m [...]

Lotus (79) Stew

Lotus (79) Stew

I had an embarrassing start in the Lotus 79 and was far off the pace in my first online practice at the Glen. It was due to a couple of reasons – I’d never tried Watkins Glen in iRacing, and I was using the baseline setup. I was doing okay in the fast sections but through the medium and tight turns it understeered noticeably. I figure that making a good setup is not unlike making a good stew, and only people with a lot of knowhow, experience and some special combination of ingredients can make it palatable. So I envision the setup gurus to be some talented chefs cooking up tweaks to make their car’s handling a perfect balance of flavors/traits. With the help of the new skidpad, I have [...]
