So, the 3 port gxII's are going down? I still say it is a very underrated engine. Mine done by racer22 has more low end grunt then my- oh never mind! Granted even geared up a tooth it does-not have the legs of a 7 port,almost but not quiet. I have yet to run the modded 7 port gen 5.5 Rex did for me. All's I'm stating is how much is to much? for me the 3 port has enough. If you can't put the power to the ground where it belongs and control it what good is it? I think modding to be more efficient is the real benefit. I may one day[soon I hope] make it into the pro level at our local tracks but driving on a national level? Doubtful even in the over forty class.But I do have fun doing this and am very grateful for the partial sponsorships I do have. So to the Ryan Lutzes out there thank you! I may never reach your caliber of driving and need the power that your talents demand. But I do have a 3 year old grandson who one day maybe the next Ryan Lutz!
