Funny you should ask about my V spec. The first one i had blew a connecting rod in about 4 weeks. I sent it back to OS and they replaced it. So far it is doing go but I dont want to take any chances. So I will only use it when I need more speed like larger races (Pro series). I am going to replace the con rod in my V spec and maybe it will last longer. Some say it is the bearings that suck and others say during break in the connecting rod gets worn. Who know, all I know is the V spec is not good.
Oh and all I have to say is WOW. The V spec 3 port is one fast engine!!
