Nick, fair enough BUT a vist to the place (nr Oxford) may change your mind about the company. It's deeply impressive.
They work closely with Prodrive, and when I was last at Owen's they we're building a batch of 32 WRC turbos (for Subaru rally cars) at a cost of £ 13.5 K per turbo
Owens do all their turbo testing/mapping on a Hoffman in house dyno (rolling road) with custom electronics/retarders. Those 4WD rollers are good enough for over 1200 BHP. Many race cars, including GT cars are mapped at up to 200 MPH sustained speed. The cooling fan is huge - with good flow/air speed due to it being a sealed cell with air exit at the far end.
