Thanks for the info. I'll probably just clutch for now. ...Unless I hit the Lottery or something 
I am seriously thinking about asphalt racing this year for fun. If anyone has a used track, ski's, or other asphalt goodies they want to part with, please let me know.

How much nitrous
I have a stock motor (03 rx1) with head bolts shooting 140 hp shot of nitrous, wet nx system and I would like to go to 180-200 shot. Can anyone tell me how much cylinder pressure a stock motor with head bolts will take and what would that be as far as hp per cylinder?

Timing key? An advanced timing key has shown to increase in low to midrange acceleration but it will lose top end. I would not recommend a timing key on any of the Apex models. With the ignition box we can adjust the timing up to 10 degrees advanced or retarded anywhere in the curve.
