It depends on the size of the track that you are running on.

The mm+12sct will have the most lowend and midrange

The mm 353 will be smoother than the mm+12sct and have a tad bit more top end.

The jp eagle tl3-t will have less bottom end than the mm+12sct and the mm353 but it has a stronger midrange than the mm 353 and less than the mm+12sct but where the eagle tl3-t comes in strong is on the top end it has the most top end speed of any more on the market at this time i am telling you the rpms this motor produces is limitless. I race at 301 racway as you know are straightaway is one of the largest in the usa and we have ever motor you could think about down here but the eagle still pulls past any motor as of know it still holds the top speed record clocking in at 67-68.


mm +12sct= $500.00

mm 353= $500.00

jp eagle tl3t= $580.00-650.00
