There are/were Hartge engine upgrades to take the s1 to over 450bhp. Rumour has it a few LHD cars had these modifications. Must be terrifying....
People will always push for horses - I find it curious!
I had a Ford GT for many years, my American chums pushed this engine to over 1,000 bhp. Why on earth would you do that?? It was rapid when it left the factory - same as the S1.
