Blitzworld is now underway upgrading the new Blitz KR2 to fit a new ROTON engine that has been on Signal 1 Radio and featured on Dragons Den on BBC2 (29th November 2005), that does not have any cams or valve springs. This engine will produce over 1000 bhp in the Blitz KR2. See the following links for more details.
The initial ROTON engine was put on a bike engine and produced FULL POWER at only 1/3 of its normal rpm
This is the Roton engine head as seen on the Dragons Den, for the bike engine.
