Hmm, a turbo-compound LSR vehicle! Don't think I've ever heard of one being
mooted before. Would it run as blown or as a turbine, or both? The only
proposed motor sport application that I've ever heard of was back in the mid
'80s when AustinRover were considering developing one for their Metro 6R4
Rally car for its Group 'S' life but the class was banned before it began.
There was a development programme in the '50s on a marine turbo-compound
engine over here in Britain based on the Napier Deltic engine. Not only did
it almost double the power output of the engine but it also had a system of
'afterburning' for short-periods where very high power was required. This
worked by squirting more fuel and air into the exhaust system upstream of
the turbine, and gave an almost unbelievable increase in power - from memory
it was another 60 or 70 percent! Now that would be difficult to legislate
for in the rules!!
