Bei der Gruppe A Mk3 lagen auch 2 bar Ladedruck an, und die sind immerhin Rennen damit gefahren.

Da er das im Rennbetrieb durchgehalten hat, geht das durchaus.

ABER: Da waren noch einige andere Mods dran!

- Cast magnesium 9 litre oil pan with matching high flow oil pump
- Knife edged steel crank
- N/A block hand picked from production line
- Short skirt Mahle/TRD pistons
- prepped rods and full floating pins

Titanium fasteners were used throughout the motor. Extensive porting and re-shaping of the combustion chambers was performed with oversized titanium valves fitted. Camshafts were of 288 degree duration with their 10.88mm lift making shim under buckets a necessity along with 100lb valve springs. Titanium cam gears were also employed. Intake and exhaust manifolds were port matched. A 65mm throttle body was used. Fuel delivery consisted of 1000cc injectors and multiple fuel pumps. The ECU was MAP based rather than the traditional AFM which was found on the the production MA70 with the exception of the homologation Turbo A, of which 500 were made.

Engine output was 580hp at the flywheel in qualifying trim (2 Bar) and the vehicle was able to achieve a maximum speed of 300km/hr on Conrod straight during the Bathurst 1000km Endurance race.

Daran sieht man auch, welchen Aufwand man betrieben muß, um sowas WIRKLICH standhaft zu bekommen.
