Mugen MF308

The Mugen MF308 is a naturally aspirated, petrol-fuelled 3.0 litre V8 racing engine built by Mugen Motorsports for Formula 3000 racing. It was supplied from 1988 to 2005, with a displacement of 2,997 cc, a 90 degree bank angle and four valves per cylinder driven by double overhead camshafts that work the valves through rocker arms, which the article calls extremely rare for a racing engine. Its lineage runs through Honda's engine work with Judd: the Judd BV, renamed Honda RA386E and then tuned in Japan as the RA387E, led to the MF308 with almost the same specifications. It powered Jean Alesi to the 1989 International Formula 3000 title and later champions, was delivered through tuners such as Tomei Engine and Ogawa Motor, and was withdrawn from Formula Nippon in 2005 when its cylinder block mould was worn out. Audi also used it in the Deutsche Tourenwagen Masters as the MF308N.
