How do you know which one (INtake or Exhaust) and how much (degrees) to change? i know you have to retard the timing for nitrous... well either way please share the knowledge.. Thanks!

 

I think your thinking of electrical timing when u refer to nitrous. But the cam gears is mechanical timing. That is the actually time the valves(intake or exhaust) with open up with relation to TDC. The timing your thinking about with the nitrous is spark. When the spark plug will fire in relation too TDC. These are two completely different things.

 

This is the type of question that belongs in the FI Forum. Post it there to get specific help.
