Return on Investment? Hi,
I was considering adding a FAST 90 and NW 90 along with flycutting for changeover from G5X2 on 114LSA to G5X3 on 112LSA. I'm currently spinning the engine to 6100rpm. Was considering (here's why the flycut is important besides the larger cam) spinning the engine to 6500rpm....
Safe enough? What do you guys think about how much HP this addition would add to the current setup (see sig).
Thanks for the input/advice.

If you don't have to flycut for the valves, then I don't think you'd need to if the springs are up to the task. If you still want to for safety, you will be better than fine. I don't know the specs on the cams you have, but I would think a stepup like that should be 10-15 rwhp or so, better lope, and changing to a 112 from a 114 should bring the curve down a bit in the rpm's and slightly more peaky. The FAST 90/90 out fo the box should be another 15 rwhp.
