Driving a 600bhp tuned Toyota GR Yaris (and how it was modified)

Driving a 600bhp tuned Toyota GR Yaris (and how it was modified). And it's still 1.6 litre! This is thought to be Europe's most powerful Toyota GR Yaris, with over 500 wheel horse power and over 600 at the flywheel. It was built by established Supra mk4 2JZ speed shop Garage WhifBitz in Monmouthshire, who were a known tuner back in the Max Power days.
Jonny Smith finds out all the mods that make this GR Yaris double its factory power without exploding, then drives the sequential gearboxed fiesty 4WD on the road (in rain).
Thanks for stopping by The Late Brake Show. For merchandise head here: thelatebrakeshow.com/shop
The Yaris' crank/flywheel horsepower of over 600bhp (when 506 wheel horsepower was proven on the dyno) was calculated using this link: www.mk5cortinaestate.co.uk/ca...

That you can make 500-600 hp reliably with very strong power curves. I don’t think these other cars had 7 speed sequentials lol but really is it a competition or is it people modifying cars because they’re just that passionate about cars and the sensation of driving enthusiastically.

Always good fun to see what people are doing with the GR's. If my other half didn't love it ours so much it would have seen the inside of some turners in already :) I've got a rather rapid "7" (north of 500hp/tonne) and honestly the GR point to point is reeeeeediciculously quick out of the box, quicker than the big power RWD machine. The grip levels are fantastic. Nothing I've had or been in comes close on twisty roads. Throwing a lot of power at it addresses the only "problem" of the stock circuit pack car - it's almost got too much grip, so getting it out for some mad lairy 4 wheel action is hard work (say compared to the big power Audi RS's, just turn off aids, throw it into the corner, power oversteer out). This one ^^^^ would be awesome fun in the dry. Well done lads! Saving this video for later !

[@GRfourfun]

Love it and admire what they’ve done and the owner for stumping up the cash, but can’t help but think in these conditions a standard car would go away from this. The standard car is just so good out of the box and one of the reasons it’s so good is you can deploy all the power all the time no matter the conditions.

[@khamid1]

It comes down to tyres for conditions. This instance had AR1s in -2 sleet conditions lol. Put some pilot rain tyres on and this basically an AP2 rally car. It would stomp a stock GRY.

[@Rookiereece]

not really when its AWD

[@SChapps]

Agreed. Impressive what they’ve been able to do with these engines and fair play the owner putting all that money into something they clearly love. But this one is just too hardcore for use on the road, I guess mostly the tyres ruined it in this weather but it’s loud, the suspension has been made stiffer, sequential gearboxes only enjoy being driven flat out. If I had one I’d keep it original to how they are out of the box which is one of the most capable point to point B road cars you can buy, but just enhance that with exhaust, intake, seats, wider tyres and a modest tune

[@adamski1400]

​@@SChapps Exactly what I've done with mine and its near enough perfect for fun and capable on the road

[@AbrahamArthemius]

Honestly i think the problem came from the type of tyres it's using. I figured if it kept the original Pilot Sport then it will behave better on the wets than the new ones.

[@ewanstewart8011]

I’m glad you like the 3 cylinder engines, I had a go in a Corsa 3 pot once sounded great, I followed a Fiesta ST 3pot the other day and it was epic but that thing is otherworldly wow 👍🏻

That's the thing, as cool as Free Valve tech is, by not being on the market (even now the Gemera is delayed i think and there's no traction with the Chinese car that's supposedly using that tech) it just hinders the development of it.
