Cant put up and tell everything... Got to leave something on the table and not constantly put up my modified graphs... people might get mad as i dont sponsor the forum for one lol But I will say this... when I did this test I looked over the engine in great detail and without doubt see areas where this engine can pick up considerable gains. So modified expect this engine to be in the 1.7s "on my X-Dyno" range with alot more power over the curve.

Actually i do I have posted it on here before I just cant remember in what section...

Here is a stock ninja .28 over layed by my modified Ninja .28 The test Analysis Report box will have what pipe and fuel was tested and if there stock or modified... But I think youll be able to tell which one has been modified.
