The 26B is an insane engine to begin with. I don’t know how similar these custom 26B 4-rotor swaps are to the real thing Mazda sent to Le Mans in the 787B, but those were pushing 700+hp naturally aspirated. And that was for reliability, otherwise they could have made 900hp!

That’s a shame, because a 610hp GT350 would have been amazing. Let’s hope for at least 550hp then.

I’m not even sure what to think about weight anymore. Or maybe the 918 is just magical. I mean how else do you explain it beating the Mclaren P1 on several tracks despite it being 400lb heavier, less powerful, and making less than half the downforce on seemingly inferior suspension?

It’s hard to directly compare downforce numbers. Ideally you want the figures to all be at the same speed since downforce rises exponentially with speed (barring active aero effects), but the Viper’s is quoted at 177 mph, the P1 at 161 mph, LaFerrari at 125, and the 918 at 186.

Same width as regular Viper tires but I suspect these things will be practically racing slicks.

It’s still an undeniable fact that adding a whole lot of extra drag to a car will hamper it in terms of high speed acceleration and lower the top speed significantly. With the exception of some types of ground effects and movable aero with a low drag mode, more downforce corresponds to more drag which hurts the…

That being said, Dodge really does need to bring back the convertible/targa/roadster Viper back. Though not as trackday friendly as a coupe, there’s been roofless versions of the Viper since it debuted, and it’s high time to bring it back, especially now that there’s a new ACR version for the racetrack-prone.

On a long track with really high speed sections like the Ring, the downforce would be a bit of a double edged sword, wouldn’t it? Insane grip on those fast sweepers (as well as any other kind of turn) and when getting on the brakes, but even though it might severely out-grip a Porsche 918 it’s got an enormous amount…

I don’t think a flat plane arrangement even makes sense on a V10. The cylinder firing order would be all out of whack, and the Viper’s got a strange firing order/crank design even for a V10. Crossplane/Flatplane crank really only applies to V8s, and even if the Viper were an 8.4L V8 a flatplane would be a bad idea…

Privateer teams ;)

The ACR won’t be a volume seller, even by Viper standards. Making it super limited production actually means it’s got a better shot at being high demand and selling out. They only made less than 200 TAs and those sold pretty damn well because it’s exactly what people that typically buy Vipers wanted: hard(er) core…

I can understand if the bike has rear suspension, but this has fixed arms. I think it’s probably more to do with mass centralization, if the rear wheel hits a bump it would move up and down way more than the center of the bike which would be like some sort of pivot point.

Street racing movies make me want to street race. Just like how watching James Bond makes me want to go and kill people in the name of Her Majesty the Queen.

It’s always a different matter when dealing with a car coming like that from the factory vs what you can throw together in the aftermarket. While you do get the economics of scale if Subaru mass produced a turbo BRZ, they would also have to make it meet emissions standards, get decent fuel economy, last 100,000+…

It seems most people talk about handling using the only metric they can wrap their heads around beyond hp and 0-60: Cornering G’s. The BRZ handles really well but because it doesn’t come stock with ultra sticky or wide tires, it pulls 0.92 G rather than 0.95 or whatever’s considered “good” these days. Never mind the…

The BRZ is pretty light though. Not saying 200hp is enough to be fast, but 350hp would give it about 8lb/hp which better than a Mustang GT/Camaro SS and pushing Corvette territory. That sort of speed won’t be cheap, especially because you can’t just nearly double a car’s power without upgrading pretty much everything…

In the case of Mustangs, it seems in recent years the tuner products end up more expensive (for what you essentially get) and an overall lower quality than Ford’s own performance offerings. They can slap on a supercharger, rock hard suspension, stickers, and maybe some sort of body kit, but if that’s all you wanted to…

It’s easy:

It needs upforce to stop the fart cannon from dragging on the road.
