Noob question but what makes the V8 Super Cars faster - do they have better tyres?

Professional drivers for starters. The cars are setup for that style of racing too...however, to be fair, you also need to take into account the restrictions a V8 supercar has that give it a disadvantage around the track: minimum weights, maximum brake rotor size, rear wheel drive configuration, they're based on the chassis length/configuration of a 4 door sedan, control tyres. Also, unlike sprints, in a racing environment achieving your best laptimes is the last priority. Top 10 shoot out is about as close as you get to that. So although fun to compare times it's not too relevant outside of the homologation.

Pretty cool times in the R35 OP, well done - I look forward to seeing the vid. Bathurst is a truly unique and awesome circuit.

V8 Supercars are genuine race cars. They have no relationship to the road car what so ever. The fact that they look similar is almost purely coincidental.

Yes they do start out with a road car but the amount of chopping and custom fab that goes into them is genuinely staggering. The front ends are hacked and replaced with custom suspension geometry, as is the rear, and there is one monumental buttress fitted to the rear end to handle the massive power levels. Their floors are completely removed and replaced with custom built in house jobbies. The driver's seating position is moved almost to the middle of the car and the race engine is moved much further aft than the road car.

On top of that, this years 888 falcon did not share a single external panel with the road car. The Ford and Holden stickers are there for little more than sponsorship.

That Holden and Ford can claim victory for the hard work that each individual team undertakes is nothing short of a joke.

Anyway, add slick tires and closed loop chassis tuning and there is no chance that any road car will ever keep up.

I'm sure the V8 is still lighter than the R35, brake would definately bigger too, power restriction.....??? I think they make around 600kw@tread and run 10 :blink:

I thought this was no longer the case. I've been told the V8 supercars are actually bigger than their road car cousins and really they are a dedicated race car that is shaped and painted to "look" like the road cars...but the resemblence stops there.

The V8's on qualifying laps get around 2:08 and sometimes high 2:07's but when you consider the differences between them and the R34GTR, that 2:13 is very very impressive. nice work!!

Not quite, about 400-420rwkw, capacity and compression limits. Pretty sure brakes are 380mm, same as r35

    • Well, yeah, the RB26 is definitely that far off the mark. From a pure technology point of view it is closer to the engines of the 60s than it is to the engines of the last 10 years. There is absolutely nothing special about an RB26 that wasn't present in engines going all the way back to the 60s, except probably the four valve head. The bottom end is just bog standard Japanese stuff. The head is nothing special. Celicas in the 70s were the same thing, in 4cyl 2 valve form. The ITBs are nothing special when you consider that the same Celicas had twin Solexes on them, and so had throttle plates in the exact same place. There's no variable valve timing, no variable inlet manifold, which even other RBs had either before the 26 came out or shortly afterward. The ECU is pretty rude and crude. The only things it has going for it are that the physical structure was pretty bloody tough for a mass produced engine, the twin-turbos and ITBs made for a bit of uniqueness against the competition (and even Toyota were ahead on the twin turbs thing, weren't they?) and the electronic controls and measuring devices (ie, AFMs, CAS, etc) were good enough to make it run well. Oh, and it sounds better than almost anything else, ever. The VR38 is absolutely halfway between the RB generation and the current generation, so it definitely has a massive increase in the sophistication of the electronics, allowing for a lot more dynamic optimisation of mapping. Then there's things like metal treatments and other coatings on things, adoption of variable cam stuff, and a bunch of other little improvements that mean it has to be a better thing than the RB26. But I otherwise agree with you that it is approximately the same thing as a 26. But, skip forward another 10 years from that engine and then the things that I mentioned in previous post come out to play. High compression, massively sophisticated computers, direct injection, clever measuring sensors, etc etc. They are the real difference between trying to make big power with a 26 and trying to make big power with a S/B50/54 (or whatever the preferred BMW engine of the week is).
    • Is the RB26 actually that far off the mark? Honestly from where I'm sitting a VR38DETT is not actually that much more advanced than the RB26. Yes, there is a scavenge pump on the VR38, it's smarter in a number of ways but it's not actually jumping out to me as alien technology. Something like a B58 or V35A-FTS on the other hand has so many surprising little design features that add up to be something that just isn't comparable.
