Let’s get one thing out of the way first, because I’m sure there’s a lot of technically-minded people who are reading this to see how it works. This is not really a “quad turbo” setup like on a Veyron, even if it sounds cool to call it that in the post’s title. It’s a custom compound turbo setup that works in a similar way to that used on diesel engines, with two turbos of different sizes working together to create the kind of boost levels and engine responsiveness that couldn’t normally be achieved with huge turbos alone.

First, at lower revs, two TD06-17C turbos start creating boost to get the whole thing going.

Once the boost levels are sufficient with the smaller turbos, these two T88-34D turbos positioned right up the front of the engine bay create even more boost with the eventual aim being something well over 3 bar.

As you can see, this is where air first enters the system. At this point, I’d like to ask that anyone reading this who has some sort of authority to talk about turbocharging to head to the comments section down below, where I will be more than happy to read your incredulous responses and/or informative opinions.

The boosted air then flows through the intercooler and into the intake manifold. Somewhere in the middle of all that is a water/methanol injection system to keep the inlet charge somewhat cool.

The thing on the right is a supplemental radiator that is plumbed into the heater core lines, since the car has no HVAC system. Despite being a bit ugly, Takuro says it works quite well.
