Your looking at the turbos up top. The Manifold is at the bottom

Oh ok, so there's an exhaust outlet that isn't shown in your photos. That makes a lot of sense now.

Pretty serious stuff! Incredibly complex. It's kinda funny. "Let's build an engine whose main characteristics are small size and simplicity, and add a heavy, large, elaborate turbocharging setup to it." Seems to work well anyhow, especially this BNR setup.

It's overly engineered along with twice as many solenoids, vacuum lines, etc.

I don't think the sequential setup adds particularly to the weight, but it certainly is complex. History has shown that pneumatic operation is not the right way to do this, but I'd be interested to see if it would work with direct actuation.

I suspect the long-term answer is going to be a motor/generator attached to the CHRA like they're doing in F1 right now (MGU-H). Use battery power to spin the turbo up, then take power off the turbine shaft to recharge the battery once it's making boost instead of using a wastegate.

Still need an intercooler, tune, and maybe a mid-pipe. I'm pumped with the numbers...

Why post a dyno video with no numbers?

Enter suspense:


311hp

no torque numbers. Dyno was held for a meet and didn't have the equipment for a rotary. I am going to upgrade the fuel pump to a Supra tt running constant 12v to it. Then get a medium stock location intercooler.
