All of the jps that I have had and have seen have been fast. Chris Whitney jps were all ways the fastest motors on the track. I have the classic 9 and my Jp r9 s blows the doors off of it in the speed department. You also have to remember you have to gear jps alot lower than you would other motors if you don't they will never get into the meat of there powerbands. By the way the top speed record for a touring car at 301 raceway was broken by Vincent Jackson last year at 65mph with his Jp tl3-t eagle with was held by c-whit with his Jp to3-t and Jamie coraddo with Murnan rb r3 at 64mph. Plus the rb c9 is much faster than the classic9-10 but the best driver will always win.
