World Series Tourers - 2015 Season (SUBMISSIONS CLOSE 25TH JULY)


EDIT 7 - THIS CHALLENGE IS REINSTATED. Following an amount of time developing and working hard to make the challenge worthy of the “world series” name. Now dates will be confirmed and a tracklist sent out! Best of luck to all of you!

Its approaching that time again where we will be racing again around the world, but first we must address the new ruleset coming in for this season. Cars must be homologated to the World Authoritiy for Motorosport (WAM) Regulations, and an example of both of the road car and touring car must be sent to the technical inspection office.

Below is a link to the regulations. Please read through this and supply both a Road Car and Touring Car the technical office.

WAM WST Homologation

Once your car has been homologated it will appear in the list linked below

FAAL (Fabrique d'Automobiles d'Alsace-Lorraine) - 1981-1986: AWD and Group B tales

This is one of those challenges where my lore haven’t caught up yet but it just looks so appealing I can’t not participate.


Is production unit <50 for the trim or overall? Because I’m struggling to get the trim under 120!

NM, I think I know the problem


That should have been 70


Are their upper limits on trim ET and/or price? Or does this challenge not need either of them?


What’s not there isn’t needed


(No , I don’t participate , sorry for that stupid question)
So high-flow catalytic converter isn’t allowed , and for example Civic Type-R EK9 1.6 N/A also are not allowed. Sorry for my bad english.


Three way, high or regular flow, are allowed. And it’s turbocharged engines only.


Is there a specific naming system?


Nope. When I put them in I’ll tag the names myself using my own system. Thanks for the question tho


Sorry to bother you one more time, but I find the turbo size is extremely restrictive. Is this realistic?


I got 513hp with the turbos. It’s not actually that restrictive if you tune well.

Edit: Up to 522 now :stuck_out_tongue:


That explains why I can’t manage to break 275.


If you are good at tune you should break 600hp/per liter or idk.


With these limitations that would be seriously impressive. Although I do think I can squeeze a little more power out of my engine


I’ve got 360bhp and I’m not the best. IT’s certainly possible to get some silly power, but I’ll leave it to you lot to figure out how.


Just so you know, the engine regulations HEAVILY favor V6 engines, as they have twin turbos, so 2x 40/40mm. With larger turbine and compressor single turbos (I3, I4, I6) can be competitive as well.


I’ve been considering what I can do to the twin turbo setup to alleviate this. I’m thinking of throwing in a smaller restriction for Twin Turbo’s but I’d need to do some testing before I do that.


To be honest, I think the lag will balance things out. On shorter circuits, despite my 522hp, there’s so much lag that the turbos can’t spool up properly.

Anti-lag when plz


I just tried a V6 and managed 460 hp.

Sidenote: is 600 hp/L possible in Automation? At least without being really peaky?

Edit: I’d also like to ask if the RPM limit could be bumped up to, oh, I don’t know, 10,000. My engine hits peak power at 8300 but still pulls hard up to 10,500. (If I really wanted it can do 11,300 w/o valve float but power falls off a cliff after 10,600.

Just hit 500 HP with some, uh, quality strats.
