More like % nitro at work.
Anyway, I think Rene C gave a report on the Pre-Worlds at Brazil. He mentioned that the engines used by the Japanese (assuming those were RR12L3 Kondo ones) were around the same as what they had.
Man Salvens excuse factory was working overtime there. If the Mugens were running 40% why did not he? Is he not Serpents best racer? How could the "unbeatable" Serpent factory team get out motored? It is no excuse in my book, he just needs to accept that the Serpent guys had not done their homework on that weekend when it came to motors, the Mugen guys had the car speed.
The pre-worlds was run to IFMAR rules, 16% nitro. This will even up the playing field when it comes to "funny fuel".
