I see Ilmor were in MotoGP too, back in 2007 they entered one race before they decided they were not quick enough, nice looking bike though...
I see when they raced in F1 they only built the engines rather than it's own team, they were the Pacific Ilmor team with Luxembourg driver Bertrand Gachot and Paul Belmondo who bought his way into the team, interesting to see that Oliver Gavin did all the testing for them, didn't he end up driving the safety car in the end
