I disagree that the mere 1000 rpm will not matter in on road racing. especially if you have your set up and a free drive train. unfortunately I also race 4 cell oval. and that 1000 rpms will make a difference of .1 to .5 seconds per lap at a minimum. For intsance, last weekend i used to identical stock motors tuned by brood, one is 1000 rpm faster, with the slower one I am about 4th after lap 1, with the faster motor I was up the the front after 1 lap. All thing equal in on road it will probably make that much difference also.
and yes I will get one. I can use another 500 to 1000 rpm!! nice ploy by trinity to make more motor sales.
What is next, maybe trinity make make a tweakable 19turn fixed endbell. not for the racers of course, it's for all of us bashers.
