Yo,
The JP engines are defenitly one of the fastest, if not the fastest engines. I live in the Netherlands, and Serpent has his factory here and are always on the track with the newest parts and engines, but they haven't managed to beat the Mugen JP combi yet 
The only backdraft of the JP is their durability.
They are not as durable as the NovaMega's or other Nova based engines.
Hmm and I thought Rene held the track record
