- What are some of the differences between a WRC and WRX car?
World Rallycross (aka WRX, World RX) and World Rally Championship cars share a lot in common at a glance but at the Goodwood Festival of Speed, Andre had a chance to look over Petter Solberg's 2017 and 2018 World RX championship-winning Volkswagen Polo R WRX Supercar and run us through just a few of the differences.
This VW Polo is closely based on a 2014 spec WRC car with changes made to fit WRX spec including the removal of the approx 34mm restrictor and fitting a larger 45mm restrictor which along with some other changes allows the cars run up to around 600HP instead of the WRCs more restrictive 350hp or so with the original WRC spec Polo delivering approx 318hp itself. An increase in engine capacity from 1.6 to a 2L VW Motorsport 4 cylinder also helps to increase the output, but while outright power figures great with both disciplines it is really the approx 650Nm of torque produced around 5,000 RPM that benefits the car the most.
The permanent 4-wheel drive Polo runs direct injection (DI) with a Bosch MS 7.4 ECU in charge of the engine and gear shifting duties. World RX rules require a manually shifted 6-speed sequential transmission and depending on the gearing the car can see up to 200kph, however with tight, twisty tracks and door to door racing acceleration is more likely to get you over the line quicker than outright top speed will. Because of this, a very aggressive anti-lag setup is used which a motorsport specific (and only 4kg..) Garrett TR30R turbocharger is set to handle, and Andre explains the differences between this and a more conventional anti-lag setup.

WRC or WRX, what is your favourite? - Taz.
the answer to any rally question is always lancia
Thanks Felix. I'll remember that for the next pub quiz - Taz.
I live nearby the "Hell" round of WRX so i have to say that 👍
I live nowhere near WRC or WRX but I love watching WRC onboards, and it seems to tax the car more.
Wish we got to see some internals of the car but that's understandable, again still an interesting video
100% WRX
Rally is the best form of Motorsport, Good content, Well explained :)
RX are much better since the crowd can see the action whole time i think 😉
would pay to watch wrx cars on wrc stages. >:D
Dude your information delivery has opened a new level..!! 🤜🏼🤛🏼🤓😎🍀🇦🇺
Top upload.
Thanks to the info provided by Andre in the HPA forum to a different person about a particular ECU, it helped steer me away from a potentially costly mistake in the future. Thanks guys. 😎👍
loved this vid. hope to see more on the topic of antilag, especially having to do with the mentioned bypass valve
I always learn some advanced rare race car mechanics here it's the best
epic content, thanks for the hard work ;) !
THANK YOU KEEP UP THE GOOD WORK.
Can we get a lesson on different anti lag strategies and how to tune them? Especially the bypass strategy style, It's very hard to find information outside of " it has a valve that puts air in the manifold"
You may be unable to purchase the tr3030r from Garrett, however you can buy one from STC (speedtrappconsulting). It runs about ~1850 USD with a typical t3 turbine housing.
A complette RX turbo is about 15-20 k dollar
Guys throw together a video w some tuning strategies regarding the als set up. Would be a cool topic everyone loves als
Interesting video as always! Although you do mention the rallycross rules allow for a 2l engine, WRC cars since 2011 including the Polo WRC ran a 1.6l engine, so the differences I'd imagine go beyond just the turbo restrictor size?
Hey there Chris, you are 100% correct. I made sure to address that bit in the video description as it would indeed contribute as well. Cheers for the comment - Taz.
The modern 1,6 liter WRC cars produce around 380 hp.
good video, enjoyed the knowledge on differences between anti lag producing. Why the F_@% weren't we given a demonstration!
You should do a video about the rocket anti-lag setup developed for Subaru by Prodrive! External combustion engine combined perfectly with an internal combustion engine.
Lol You are talking about the simplest ALS setup that has been used for more than 30 years, he described it before he describe the modern form of ALS strategy with air going direct to the exhaust manifold instead of going through the engine...or do you think Prodrive has been to the moon with their "rocket" als strategy ? looool
@@mattiasandersson3444 haha don't worry I can tell you have no idea what you're talking about! Do some more research first! Prodrive system produces full boost at IDLE
@@JustNieman lol my syvecs ecu in my built cdb ej257 do that too. Most aftermarkets ecu do that without problem. I have 25 psi AT IDLE in my STI and your are a fucking idiot if you think prodrive and there ecu are the only People that can do that. Looool Have you lived in a cave the latest 10 years? Its really avious that you have if you think that is something special.... Hahahahaha
The "Rocket" was/is really just refined variation on what is being described here, except Prodrive fabricated a combustion chamber into the system.
The "Rocket" setup is actually pretty simple engineering and was on the threshold of the WRC regulations.
Oh, and as good as I am sure your build is, you REALLY need to do some research before you compare it to a WRCar setup.
@@tbtstt i f you dont knew it already i can tell tou theres absolutely no need for a fucking combustion chamber to get full boost on idle and that was the only fucking thing i compared, cause i have full boost at idle in my streetcar STI-16 with Syvecs ECU and 705 bhp. So if some one shall read so is it you when you Think thats so fucking fantastic….lol
Only 500 likes are you kidding
Brill vids mate
4bar boost on tap...this iam missing in my life :) Just for overtaking people :)
Realy torque power monsters!🙂
🔥
Love your videos but putting images would be even better and not too difficult! :)
Yes we didn't get much b-roll of this car sadly. It can be harder than you'd think when you're at an event and 50 people are trying to look at the same thing at the same time. We do our best though - Taz.
@@hpa101 Dont get me wrong you do a superb job anyway!
Wow best Sport in the world
Always an exciting watch! - Taz.
forgot to talk about the completely different suspension...
Isn't another big difference that WRX cars have the engine in the rear?
Nope
How is he able to relay so much information without reading it off a piece of paper?
Years of practice and a good amount of research and help from those involved with the car beforehand too =) - Taz.
if only the video was longer haha
Ive actually got a TR30R VGT on my SR20 its pretty baller but the bearing system is basically GT30 its pruduces great response and really good pressure ratios map:emap
Who gave the thumb down?
The losing teams
The green people did I would imagine, since they hate a combo of wheels and noise...😩😩🙈
Just a quick note. WRC are 1600cc
The capacity of the Rally Cross cars is increased - Taz.
Didn’t hear any anti lag ?
Sorry Tristan we're more about the tech side of things than just the pops and bangs, although this car was very hard to get footage off at Goodwood too. Apologies if this isn't to your tastes, but you will be able to find WRC and World RX footage of this car on CZcams I'm sure - Taz.
Maybe call the video anti lag tech talk
The video is indeed already labeled as exactly that with 'Tech Talk' even being in capital letters 🤘- Taz.
High Performance Academy yeah I know but you can’t see that on your phone
16 thumbs down??
How how does a filthy normie like myself get my hands on a retired drive-train. 10k for your beater WRC engine so i can make my A5 peel out
Well if you were on the Ford Ranger facebook page they would tell you to do an LS swap......
Subaru WRC Spares will sell you everything you need. You might need to up your budget from 10K though...
I’m not a big fan on electronics talk. In fact, I find it about as boring as the movie “Capote”. But if you did an hour long video explaining the intake and exhaust secrets and theories used by Grumpy Jenkins’ pro stock drag engines, that would probably be my favorite video ever.
He once called a phone sex hotline and asked her to talk about ECUs and traction control programming for an hour.
That is the reason why we have a Toll Bar on the HPA phone line now. I miss my 0900 horoscopes ;( - Taz.
This guy's accent, my gosh!!! It's like nails on a chalkboard.....
Sounds like you're using your chalkboard wrong, I'll see if he can do a lesson on that for you 🧐 😉 - Taz.
34mm? So a world rally car breathes through a tiny opening about an inch and a half in diameter?! Jeez. At least in NASCAR they have four holes.
That was the last generations 2 liters wrc cars that were restricted with a 34 mm restrictor. But now it is 1.6 liters WRC-engines with a bigger 36 mm restrictor and the powerlevel is about 380 BHP.
Dude, u provide good knowledge on cars. But, I am sorry to say. U delivery the content in such boring manner that it can put anyone to sleep. U speak like a professor of engineering college. Even when taking interviews, u take ages to ask a simple question.
I hope you find a channel that suits your learning style, we're all different =) - Taz.
Actually, I understand and respect that, but if u want to gather more audience to ur channel. U ve to change ur style little bit(make it more simple understand the language) . Anyway, love ur content keep it up.
Start learning English ASAP!!!
Oui =)
