So in the true spirit of international motor racing, we slow 'em down, rather than speed 'em up.
The prototype race is destined to be an aside anyway, so who really cares?
It's a bit ironic really, that a team like Champion Motorsports invest so heavily - only to have their car nobbled by the organisers, so that it won't run faster than a Courage (or a DBR9 for that matter, on the straight, at least).
