Now I see why all the fuss !    about the FX

    On October 10th 2009 I got one of these OS .25FX .   Well yesterday I bolted it to a big wooden block,
  The same one I had bolted the ASP .25A  and the BRAT .28 and I could not belive the difference.
  The ASP turning a 10 X  3 up to 13.700
  The Brat .28 turned 10 X 3 up to 12,900
  The OS .25FX with 10 X 3   up to 15,000  I had to put my foot on the 6" X 6" block
  as this engine was pulling it across the parking lot .
     All numbers were done with 5% nitro and 22% castor oil runing fat and doing the pintch.
