Ya I've learned alot from watching and helping my buddy Ryan carter build and tune this car, I get to go pick her up tomorrow . I choose this cam because its different not alot of people use it and with the right tune its good! With the nic and rockers it had a tad bit bigger lift then xp. My buddy called me last n it when he was tunning and said he seen in touch 20 lbs of boost . The fuel pump in it is alot bigger and we are pushing some gas in the thing hard. I can't wait to go to track. Oh ya the exhaust cut out is so pound ill get another video and some blower whines soon. My buddy Ryan who has built many of 3800s said its the loudest blower he has ever heard on a Gp.
