14.2 or 14.3 was the best I remember people running stock back in the early days. I can't remember anyone off the top of my head that ran heads, cam, intake and headers setup; that still comes on to the forums. You might be able to sift around RMGTO.com to find your answer.
Ill be honest, its not the best and for sure isnt like bandi. Up untill this season, its been run by people who didnt give a shit about drag racing, and it was very obvious. But, personally. I have had more fun with pmp than bandi when i was running my 12 second bug. Pits arnt on asphalt, its closer to the springs , and there is shade, something that bandimere doesnt have. Lol. They redid half the track 2 years ago so its concrete to the 1/ 8th. I have been on the track where the prep was good and could 60 foot as well as i could at bandi, and ive had my bug feel like it was on ice in the top of 4th gear. Prep quality has been hit and miss in the past. I am hoping better managment will help. But if you haven't been, its worth giving it a try. Imo
