De Tomaso Pantera 1971 nr THPNLL01267 that I bought in Italy in the spring 1984.
It was converted to a twin turbocharger setup
with two Rotomasters ,
Weber carbs with a blow through system.
7.5/1 compression with a maximum boost of 18 psi with water injection.
It is now in the garage for rebuilding.
