WTCC 2011 cars building

[cossie8]

Hi guys,

I`ve decided to build a FF car following the WTCC regulations.


the basics:
1170kgs min.
1600 ccm Turbo
max. 8500 RPM

any suggestions?

Hmmm... An EG or EK Civic could be built to those specs (though they may rev too high with the "wrong" mods)... Also the Toyota AE111s (Sprinter Trueno and Corolla Levin, both '98s I believe) are nearish those specs and can be turbocharged.

That said all of those are a bit light and require ballast... Can't really think of anything with a 1.6 that's actually heavy enough as they don't really exist.

Edit: Weight regulation is actually 1170kg now it seems.

Mitsu Mirage, Pug 207 GTi, Mini Cooper S turbo, Xsara VTR I think..?

My first thougt was the volvo c30, but the engine is too big

the real life C30 specs:
http://www.fiawtcc.com/Cars_Details.asp?idCar=38
315 bhp @ 6000 rpm
440 nm @ 4000 rpm

maybe I can downgrade it, to get the similar feeling!?

(I`ve changed to 1170kgs, the volvo is only 1150 kgs, but it`s some exeption)

I`m not using any standard cars, so there`s not much 1,6 cars

Not sure of engine size for Citroên C4, probably to large so how about the C3 or one of the other Citroêns, also look at the Peugeots and Renaults. All three of the French brands have cars that can be turbocharged and tend to be a bit on the heavy side. Finally what's the engine size of the Volkswagen Golf's?

as far as I know all of them around 2000ccm s, civic can be the answer...

C4 - 2000cc
Golf IV - 1800cc
Golf V - 2000cc

The Nissan March 12SR '07 has 1240cc and revs to 8000rpm when you max it. Do you have a power requirement? The March will only get to around 220bhp so it may not be the best option if you want something with 300bhp.

Otherwise the EK Civic Type R is a great fit, but as Rotary Junkie said, it's easy to raise the rev limiter past 8500rpm.

 

[cossie8]

the IRL cars about 310-320 BHP,

if U tune the civic, do not make any engine upgrade, only the turbos, not to pas over 8500 RPM

Peugeot 207 GTI '07
NCD
Displacement 1598cc
With High RPM Turbo Kit and all engine modifications makes 371HP and 287ft-lb torque@5400 rpm. Max HP is actually achieved at the 7900 rpm redline. Stock weight is 1260kg, stage3 weight reduction and window weight reduction drops weight to 1048kg requiring 122kg ballast to bring it to 1170kg (added to position +50 this gives a 57/43 weight distribution, stock the car is very nose heavy with a 64/36 weight distribution.)
Car has 497PP with ballast added to reach 1170kg.

Mini Cooper S '05
NCD
Also meets weight and redline standards but uses a supercharger to make its 321HP so not sure if it works.

Toyota Vitz RS 1.5 '07
NCD
Engine displacement 1496cc
Can reach reach weight but its going to mean adding 170kg to the stock cars weight. Also it only reaches 285HP and 214ft-lb torque though both are achieved near its 7700 rpm redline. (Max HP at 7400, max torque at 6900rpm) Makes it a good car to drive automatic.

the new Mini Cooper uses turbo, basically same as the 207 GTi.

Yeah hadn't got to it yet...I know the '05 with the supercharger is a better performer and makes more power than the newer cooper though.

Okay '07 Mini Cooper S weighs 1210kg stock so you'll need at least stage 1 weight reduction (that drops it to 1137kg)
With full engine modifications and High RPM Turbo kit you get 275HP and 248ft-lb torque engines shows extreme drop off between peak power and redline so need to use mt. Redline is at 7700rpm, while max HP comes at 6200rpm and max torque at 5700rpm.
Note actual HP and Torque will be a little higher as I didn't break this car in.

So far as long as there is no PP restriction the Peugeot is the best of the bunch based solely on specs. Of course I'm ignoring all the standard cars that meet the specs since the OP wanted premiums only.

Honda CR-Z
NCD
Engine Displacement 1496cc
Stock weight is 1130kg so you'll need to add weight. Might be better to give it stage 3 weight reduction before adding weight as that allows for a 50/50 weight distribution. (Note if you do Stage 3 weight reduction do not do window weight reduction as you will need 199kg ballast to reach 1170kg.)
With High RPM Turbo Kit and all engine modifications the car makes 319HP and 240ft-lb torque. (Note these will actually be a bit higher as I've not broken this car in yet.) Redline is 7900rpm and peak for both HP and torque is fairly close to that at 7400rpm for HP and 5900rpm for torque with very flat power curve and almost no drop off between peak and redline.
Liked the CR-Z enough that I'm currently running it in the Compact Car seasonal races to break it in. Even at the 1170kg the car requires a lot of power limiter to make the 450PP limit so needless to say its easy to win with even on SS tires.

Just found this and thought the OP and others might be interested in the information. Could form the basis for an interesting shootout or online racing league.

The rulemakers have announced the applicable weight restrictions for cars eligible to compete in the 2011 FIA World Touring Car Championship season, which will see two drivetrain configurations and three different engine configurations competing head-to-head. Between front-and rear-wheel-drive powertrains, there is also the new-for-2011 1.6-litre turbo engine, or the older-spec 2.0-litre turbodiesel, or the 2.0-litre normally-aspirated engine. Cars running the 1.6-litre turbo engines will run with a base weight of 1,150kg for front-wheel-drive models (the Chevrolet Cruze) and 1,170kg if rear-wheel-drive (selected BMW 3-series models). Cars running the normally-aspirated 2.0-litre engine will run at 1,150kg if front-wheel drive (the Chevrolet Lacetti and SEAT León TFSI) and 1,155kg (older-spec BMW models). Turbodiesel cars (the SEAT León TDI) will have an 1,170kg base weight. All competitors will start the season with a further 40kg compensation ballast attached, above the base weights specified.

Look for me to do some tunes matching these specs soon.
If anyone can give me a link to a more detailed website regarding the regulations it would be greatly appreciated.

I made the volvo, fully tunned it except the turbo, left the standard one, turn down the power to 315 BHP, and the torque is around 43 kg*m, it`s around the same 440 Nm, we can say the specs around the same as the real car.
