THUNDER ENDURO
So what is Thunder Enduro?
It is a racing series run on the Forza games; it ran for a number of seasons on past Forza titles. The races are longer in length and they also have success ballast put into them. The faster drivers win the Championship, but they have to use race craft as well as pace, as the racing gets very closed up from the front of the grid to the back through the season.
How does it work?
You start the season with a set Pi (Performance Index) of 750 (780 in Season 2). As you win races, your Pi goes down; if you finish near the back the Pi goes up. The Pi moves between 675 and 800 of the season (between 725 and 820 in Season 2).
Cars Allowed?
No track toys, no SUV's or spec racing cars. Cars most be able to run in a PI of 675 to 800, with race exhaust, max tyre widths, race tyres and Forza aero at every round. Please note, some cars will be allowed to run the bunny kit or other aero that acts in the same. Please contact the admins in advance to check and get the ok. From season 2 the cars need to have those bits installed and be able to run at the lowest Pi, if when installed they are slightly over and a engine, drivetrain or other modifications take them on or under the lowest season 2 Pi of 725, this is totally acceptable. But that drivetrain must remain for the season as above. The key point is your car has to be able to race at the lowest Pi with Forza Aero front and back, maxed race tyres and racing exhaust. If you have any questions then please contact us.
What decides the Pi Change?
Winning a race sees a Pi drop of 30, second sees 25, third 20, and this goes through to 5Pi for 6th. If 12 or more cars are present, the last 5 finisher gain Pi, so 12th would be able to add 25, down to 8th place adding 5Pi. These Pi’s are for the car for the next race. No one can go below 675, or above 800. The PI’s for the next round are posted within an hour of the race finishing.
Sounds Complicated?
It isn’t, all is listed for you straight away, giving you at least a week to build and test a car with any changes.
What happens if I can’t get dead on a PI?
The Pi is a maximum, not a set target. So if you are listed at 690, you must be 690 or below. If your car doesn’t go to the minimum Pi it will be disqualified of all past points and you will need to pick a new one. So check it does before the season starts.
What happens if I miss a round?
If you have already raced, you use the same Pi that was given to you in your last round. Missing rounds does not see a Pi rise. If you miss the first round(s), you will then have to start as the same Pi as the lowest car listed.
How many rounds in the Championship?
10 round Championship. Races 2 to 9 will be with the variable Pi, but at rounds 1 and 10 everyone runs as 750Pi, except the bottom 5 in the championship at the last round, they will run at 755 to 800. To qualify in the bottom 5 you must have done 8 or more rounds.
How Many races and Length of them?
One Thunder Enduro round a week, lasting around 45minutes in length. A support race will join the series later in the year that is a short 15minute race in length. Thunder Enduro races are due to start at 8.30pm UK time
Do I have to Pit?
No you don’t, due to the length of the races; all pitting is up to you. Think you can do 24 laps of Spa on one set of tyres, then go for it.
Can I use any car?
You can, as long as it can be altered within the maximum and minimum Pi’s. Also a team must run the same car, and each team must run a car not already selected (First to enter on the series page will get the car they want). All cars must have maximum tyre widths, race exhaust, race tyres and Forza areo front (or acceptable other aero as above) and back for the whole season. Also when entering, the aspiration (turbo/non turbo) of the engine and drive train must be registered and cannot then change at anytime. Everything else can be altered within the Pi for the car. For a new season, the team using a car in the season before, has first pick on whether to keep that or move on to something new.
How do the points work out?
Points are given for race position, but also bonus points are given for leading a lap, fastest clean lap and also beating a car with a higher Pi. Please see here
Do you have a team championship?
Yes we do. In season 1 the points are 10 down to 1 for the top 10 finishers overall. For season 2 the team winner is based on adding the race time together of the two team cars. Then that total time is halved to give the team time. Points are awarded on these positions. Teams though do get bonuses for PI overtaking and fastest laps. The team do not run the same Pi, only the driver does that. If a teammate cannot show up (or disconnects mid race) leaving you with one car, the time of the single driver will be added to the slowest driver from another team and divided by two. That way teams don’t lose out completely with someone unable to show. Don’t forget the Joker round. 24 slots are available on the grid, and these are taken at a first come basis. If a team fails to enter for two consecutive weeks, then there place becomes available.
What’s the Joker round?
Every team and Independent can play a joker between round 3 and round 9. In that the points for the team / independent are doubled at the one round. You must call your Joker within 24 hours of the race starting. This will not happen until season 2..
Can an Independent take part?
In season 1 we will have an Independent Champion, who will be the highest scoring 1 car team in the Team Championship. We don’t have an independent as such, all enter the team Championship. This is why the two driver teams have the total time divided by two. The disadvantage is an independent doesn’t qualify for bonus points or get any points if they don’t race. Unless of course they become a two car team midseason. From that point they follow the same rules and benefits of the two car team listed before.
Can Teammates Change?
They can once only, but only before the start of round 7. They cannot make a second change or revert back to the original driver. The new teammate must enter in the car vacated, for build and drivetrain.
Dropped Scores, AM and PRO?
No AM or Pro championships. The PI’s even up the grid and equalizer many of the speed differences. No dropped scores either, all 10 rounds will count.
Just a Teams and Drivers Championship then?
No, we have the Pi champion, based on the driver who has beaten the most cars of a lower Pi, and also the support Champion. Fastest lap winner as well. This is the fastest clean laps added together through the season. Anyone with an unclean lap, get the slowest clean lap plus 110% added together for their time. Anyone missing around get the slowest clean lap plus 150% added to their time. A class championship for AWD, FWD and RWD, and a Forever Forward winner. Idea is that everyone has something to go for through the season.
How is the Grid Set?
Round 1 is random, from round 2 it is the fastest clean laps from the race before, followed by the fastest unclean laps.
What are the Support Champion / Race?
Will be annouced later in the season. We will demonstration rounds before a full championship in season 2. If you don’t want to take part in the support race its fine, you can still run in the Enduro.
When does this Start and what night?
Media Night is on the 26th June, Round 1 is the following week at Silverstone.
What does the series offer?
Close racing with cars that suit each driver. Full race write ups for each round and season reviews and previews, plus a weekly magazine.
Who runs the Championship and administrates it?
The media and regs for the championship is looking looked after by team DART, but they will not be involved in any other admin or Si's reviews raised. The aim for season 2 is for all that took part in season 1 to have a vote in the direction of the series.
What happens if we have an incident in a race?
You have 48 hours to submit to the admin page, but only after you have spoken and discussed with the other driver(s) involved. A response from both (all) parties will need to be supplied to the admins. Any incidents will then be reviewed by the admins, and they will change race positions if it is needed, but any changes will not effect the Pi of cars only championship points or starting positions for the next round will. We are hopeful most issues will be sorted out by the drivers themselves.
Any other question, then please ask. :)
