The Most AGGRESSIVE Anti-Lag? | Petter Solberg's WRC to WRX VW Polo [TECH TALK]

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.

[@jbm3458]

Rally is the best form of Motorsport, Good content, Well explained :)

[@alvinchan7746]

would pay to watch wrx cars on wrc stages. >:D

[@MafiaboysWorld]

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. 😎👍

[@stevesloan6775]

Dude your information delivery has opened a new level..!! 🤜🏼🤛🏼🤓😎🍀🇦🇺

[@andrewjoeljackson4653]

loved this vid. hope to see more on the topic of antilag, especially having to do with the mentioned bypass valve

[@kristoman111]

epic content, thanks for the hard work ;) !

[@El_Chompo]

I always learn some advanced rare race car mechanics here it's the best

[@sabercruiser.7053]

THANK YOU KEEP UP THE GOOD WORK.

[@MofabLLCDenver]

Guys throw together a video w some tuning strategies regarding the als set up. Would be a cool topic everyone loves als

[@aiGeis]

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.

[@Skater3z3b]

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"

[@jameslowry3208]

good video, enjoyed the knowledge on differences between anti lag producing. Why the F_@% weren't we given a demonstration!

[@chrisroberts9905]

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?

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.

[@stindeee]

4bar boost on tap...this iam missing in my life :) Just for overtaking people :)

[@carlosgirao8600]

Realy torque power monsters!🙂

[@DR991_]

Love your videos but putting images would be even better and not too difficult! :)

Wow best Sport in the world
