Check your toupee: 9ff's 997 Turbo cabrio TRC 91

We can't imagine having 780 HP on tap in a convertible, but 9ff has realized the ridiculousness and created what's likely to be the fastest drop-top in the world. The German tuning haus has taken the 997 Porsche Turbo convertible, stroked the 3.6-liter six to four-liters, modified every conceivable part of the motor, all in an effort to reach a top speed of 237 MPH.
On the outside, the only thing that distinguishes the TRC 91 from its "sedate" ancestry is a set of 20-inch rollers, upgraded brakes, a revised front grille to increase airflow, a couple of aero bits and a trunk lid made entirely out of carbon fiber.
The 4.0-liter mill was actually de-tuned from the hardtop model, which creates 910 HP and 671 lb.-ft. of torque, and allows the rear-engined rocket to make it to 60 just after you count to three. Insanity. But it's our kind of madness.

Cause they swapped in a bigger turbo, does that mean it's torque band is much narrower? As in, it's turbo lag is just too long?

you never read the modification they did to the engine... beside the increased displacment from 3.6 to 4.0l there is nothing untouched at this engine.. turbo lag is not a problem of a 4.0l turbo engine.. we are not talking about pumped up 2.7l Skyline dyno queens..

also, aren't the turbos in the 997's the new fangled variable vane type that supposedly eliminate lag at any rpm or at any time for that matter
