Rob Dahm's Turbocharged Three-Rotor RX-7 Is An 835bhp Dyno Monster
Entrepreneur and serial rotary enthusiast Rob Dahm is back on our screens with his totally reworked three-rotor RX-7. Brace yourself for noises so good you might need to cross your legs: eight years after the engine was originally put together, the car known as 20b is back for its latest and greatest dyno run.
Make that 42 dyno runs, to be precise. New wiring, new coils, a new ECU and new injectors in the eight-year-old engine kick proceedings off with a 618bhp pass, but the fuel pressure is found to be low. As the video runs through, the power rises, tweaks are fixes are applied, the car seems to set itself on fire a couple of times and there’s a whole heap of fantastic rotary ear-nectar.
Ultimately Dahm and the dyno team fill 20b with racing fuel and, on the 42nd pull of the night it recorded a staggering – and pretty damn violent-looking – 835bhp at about 7300rpm, along with 620lb ft of torque.
Just a week or so ago, Dahm posted a video (above) of the car firing up for the first time. He’s got to be pleased with the results so far. Now, if he can just stop it trying to set fire to itself…

This is what Rob said to his wife/girlfriend

835hp
More than an aventador
From a 4 rotor thats kind of impressive
3 rotor
835 at the wheels though. The Aventador has 720 at the crank, so there is a big difference. And the FD is way lighter than a Lambo.
Why would you make a car so fast and so unpractical and cannot be used as daily and also why would you must have a big power to drift?
He’s not drifting or daily driving it. It’s just a weekend fun car/drag car
You seem to be on the wrong website.
Dahm that thing sounds good.
it has 835 whp not bhp btw
My only question is wheres the 4-rotor
It idles like a v8 kinda
Only three rotors? Real men use four.
