With no official times to work off it’s hard to tell who is quickest, but looking on the track and talking to drivers its clear that the Shepherd team of Pietsch, Schaefer and Spanish racer Carlos Peracho are quick, while for Serpent its Salven who is still turning fast laps along with Mark Green and Oscar Cabezas. For Mugen, Rick V is doing some very fast laps as is Motonica team driver Dario Balestri. A lot of the top guys, such as the Italians, that you would normally expect to be quick are still working on choice of body and engine pipe combination before focusing on putting in really quick times.
It is precisely that search for time that has lead some racers to try fuel with a lower nitro content, with some drivers trying both 20% and even in some case 16%. With Spanish fuel firm Merlin present trackside to support their drivers, it seems that those racers using their fuel are the only ones able to try this. Merlin team driver Oscar Cabezas, who tried the 20% mixture, believes there is little or no noticable power difference and he did get longer run time, but for him personally there is still some run time needing to be found.
