Power add-on options
I'm planning on putting in my request to Santa for this year and looking for feedback from members who currently run these options.
1) Nitrous: lots of options/manufacturers and relatively cheap initial cost. Big negative for me is the severely limited options for re-filling the bottle in my area. My research leads me to believe that the max power gain is 50 hp on stock motor internals (would put me at about 225 hp total). I am concerned about changing plug temperature and timing for the nitrous will make the bike un-ridable under non-race conditions.
2) Turbo: Limited options, significantly higher initial cost. Appears to be biggest gain in hp on stock motor internals (average claim is about 270 hp at 6 lbs of boost). Am I correct in hearing that the added pressure is tearing the air-box filter resulting in it going through the motor?
3) Head work: A couple specialty shops are claiming 215+ hp from porting, valve work etc. I have the least amount of information on this option with respect to the plus/minus of going this direction.
The option I end up with will be run on stock motor/clutch internals. I'm reasonably capable with a wrench, but by no means a professional mechanic so reliability is extremely important. I still intend to ride the bike on the street but will make 1/4 mile runs each week during the race season here.
Thanks in advance for the feedback.
