The 1932 Jamieson Streamliner engine running dry sumped on a methanol, ethenol and water mix with a two lobe Rootes blower giving 22-24 lbs boost developed 74.5 bhp at 8000 revs. Max revs 8500 for no more than 10 seconds !
This was developed into the sprint car driven by Kaye in 1934, which on alcohol sprint fuel reputedly developed 85 bhp at 8500 rpm with 24 lbs boost according to The Source Book on page 418. The block was apparently held to the crankcase with thirteen studs.
The picture above of the clutch came from a set of pictures of the Petre engine from a post-war UK Club meeting.
