Mustang Challenge Series

The FR500S Mustang is a race variant of the street Mustang GT. It uses the basic street car as a base and then adds on the appropriate race parts. Many of which can be ordered from FORD Motor Company itself by the general public. The FR500S uses the factory 4.6L V8 from the Mustang GT. By modifying the intake head and running a specially designed X-pipe exhaust after the rear axle while keeping the factory two and a half inch pipe, the engine will now achieve 325hp at the crank, only adding 25 horsepower over the factory engine. It also runs a special flap in the mufflers that open at high pressure for less backpressure and better flow. All of these parts are available for purchase directly from FORD. The transmission is the same as the factory 5-speed but has had the internals replaced for more durability. The ratios are the same as factory. The rear end is replaced with the typical 9” that is used by most ford owners in a racing setup, and is also run by NASCAR in all of their cars. The factory car runs around a 3.50 final drive ratio, but for purposes of this being a video game and having to run the same setup on every track, we will be using a 3.73 final drive. The FR500S also used a slightly shortened final drive instead of the factory gearing. Other than these minor changes to the driveline, FORD has also given this car a fully adjustable suspension, adjustable aero, carbon fiber hood, and runs DOT approved BFGoodrich g-Force R1 racing slicks. Each car is to weigh exactly 3,600lbs with the driver in the seat. The real life series that these cars were built for only ran for a few years. It was incredible to watch if you never got the chance to. You can find videos on youtube if you would like to look some of them up. Since the Mustang Challenge has stopped running, the FR500S now runs in the SCCA World Challenge series but has been altered slightly to meet spec for the series. There are several other variations of the FR series Mustangs available that are run in other racing series world-wide, but we will stick with this variation.

In this series we will be visiting some of the best tracks that the United States, available in Forza Motorsport, has to offer. We will visit the high banks and high speeds of, the slightly less known but much more fun than Daytona, Sunset Speedway, all the way to the heavy braking and ups and downs of Road Atlanta. Running an almost exact build to the FR500S Mustang that was run in the Mustang Challenge Series, we will be driving the purpose built FORZA edition FR500S weighing in at exactly 3,600lbs with a crank twisting 325hp. The cars are all equal and the only difference will be the tune you choose to run. Be sure to pay special attention to the rules section to see what is and is not allowed for your tune. Everyone is in an equal car and has an equal opportunity to win. The racing will be close and tempers will flare, but this promises to be some of the most fun you can have on four wheels. So drivers grab your helmets and meet at the line because it’s time to find out who the fastest driver is in the Mustang Challenge Series!

Rules:
Have fun
Race hard
Car Setup changes- A basic tune will be sent to you upon sign up. Each car will have a final drive of 3.73. This is not to be adjusted for any track. Also the camber will be sent with the front camber at -3.0 degrees and the rear at -1.0 degree. This also is not to be changed for any track. Downforce is up to you what to run but must remain between 100lbs rear and 140lbs rear. Front aero must remain between 80lbs and 100lbs for every track. All other adjustable parts may be adjusted as the driver desires.
Some of the adjustments I can not tell from the replay and some I can. If anyone is caught not running a legal setup, I will look into the matter and if found guilty the driver will be asked to retire from the series. I don’t see this happening I just have to put it in the rules. For the things that I can’t tell from replay I am using the honor system.
Basic rules are expected to be followed- Call out when entering and exiting pits, No “dirty” driving, keep quiet during races.
There will be NO restarts due to careless driving, if you take damage from anything that was not caused directly by lag then you will have to run the full race with damage. Lag incidents will get a restart, and only one. Because of this be sure to play it safe in the opening laps and keep clean, it could be the difference between a podium and a DNF.
If you are involved in an accident call out where you are on the track and make sure the track is clear before re-entering the racing surface. The fault is yours if you re-enter the track and are hit by an approaching car. These cars are 3,600lbs and can’t just snap the wheel to avoid another vehicle.
There are no required pit stops during any event but the pits are always open if you take damage.
Anyone who is involved in an accident must remain in the race until it is complete. If you back out of the race for any reason other than the car has flipped or engine has sustained tremendous damage and you can’t move, you will receive 0 points for that race.
All replays will be reviewed by officials and anyone caught with an illegal build or tune will be approached privately before publicly punished.

you already know im in. anyone that has doubts ill put up the replay in my storefront. amazing racing.

Thanks sainted. That would be great.

I'm interested to check it out. What is the resulting PI range? High B-low A?

Its a low a class. For the overall weight of the car, it is surprisingly easy to drive. Its not exactly nimble but its very stable.

Cool, look forward to checking it out.

its close racing too, i had trouble chasing clutch down at road america and that rarely happens in the series you know?

That's why I'm doing this series. Its one thing to blame pi if you lose or say that you're only losing because your car can't keep up. Here its all about skill. A real life build on a real life car with a very limited tuning curve. That leaves it all up to the driver. Hopefully we get a fair amount of drivers and we can prove who is really the best. Let the trash talking commence.

IMMA' SKOOOOL Y'ALLLL

I will keep my eye on this event .. All depends on day and time and some settings..

Nah. He's doing away with the whole shebang and is starting from scratch.

Haha that would be hilarious lsa. GT and GS will be here for sure. Pretty sure ST will stay also, it is very popular. Its worth keeping an eye on I think.

Sorry about the delay guys. I was puting in time at the ring. Looks like it paid off. Anyways, now that there is a break in the action, I will be running some extended test sessions on Wednesday night I would like to see a large turn out. No need to sign up, just post here that you would like to run and I'll be sure to get you a car. No special paint or anything for this, its just a test and tune. More details on full series to come.

Im in if i can make it
