Alternator options

[Stephen@NCAutoUSA]

If you have or can arrange to borrow a clamp-on DC current probe, you could measure the output of the OEM Denso alternator at idle. Do this with the air conditioning running, stereo on, headlights on (and crank the EPS if you have EPS). That will give you an idea of the likely worst case steady operating condition for the alternator (high loads and low alternator speed). If the output curve for the reduced size alternator indicates that it can deliver that amount of current at engine idle speed (after calculating the correct alternator speed) then you are probably good-to-go. Everything gets better as engine speed increases as long as the alternators maximum speed is consistent with the NSX's 8000 RPM red line.

Great idea!

research will be key here so it is a great idea, the lightweight alternator bracket has not materialized yet so a bit more time spent to find the best solution will make a better product
