Recently Superlite Cars built one of their SLCs for a customer who wanted lots of power.
So they started with a Katech Air Attack 427, and Superlite added a few more bits like twin Borg-Warner EFR 9180 80mm twin-scroll turbos with ceramic ball bearings and turbine speed sensors. Then they fitted two liquid-cooled wastegates, liquid-to-air intercoolers, a custom exhaust system, and a custom aluminum intake, all controlled by a Holley ECU and boost controllers.
Early dyno runs showed a lot of potential, but when a full-throttle run was attempted, the dyno they were using was maxed out at 1200 whp, even as the car itself was still making lots more power. So the dyno sheet only shows 1200...
Here's a pic of the car:
Of course, the bodywork is off for ease of tuning; for those who haven't seen an SLC before, they look like this in race trim:
Or this in street trim:
The dyno sheet:
The car was hopping pretty violently on the dyno, and then started overpowering the rollers, so they backed out.
Hard to know how much power the car really makes, but as Rolls Royce used to say about their engines, the power is "adequate".
This is a street car, but has more than double the power that the green race car above had when it won the NASA Super Unlimited National Championship.
Its a shame they didnt design a door to let the windows go down. Something so basic to engineer around. Other than that, absolutely beautiful and can't imagine driving that on the street in that light frame!

Looks like a Graziano, as from a current Lamborghini and Audi.

It's supposed to look and perform like a Group C race car, and that's the shape they had, so that's how it looks. They didn't have opening windows, either.
I think in practice you get used to them, or you can have a 2-piece window that opens (or removes for driving) the lower portion.
