Comptech SC Alternator Question/Discussion

[A.S. Motorsport]

I know new CTE and SOS kits running of CB7 alternators.

What about this one?


HIGH OUTPUT 130 AMP ALTERNATOR 1992-1996 HONDA PRELUDE



And this one says new NEW ALTERNATOR 1992-1996 HONDA PRELUDE 100amp

Mike,

In my research I seem to remember this company popping up on the Prelude forums. They shipped them with smaller pulleys to "up" the output amperage. My memory sucks but it's a popular trick for the car audio guys. Something to check on...

Hey Man, Thanks so much for watching out for me. Saw those while searching. I would like to replace the one from my kit before installing in a few weeks.

Did i just say a few weeks? FINALLY

Congrats! Looking forward to it. If I can help just let me know.

I appreciate that man, Thanks


Ok, still looking this over and here is what i found. Not much technical info so this info is from the repair manuals per the load test.

OEM NSX @2000rpm approximately 82amp (from chart above)

OEM prelude @2000rpm
F22A1 - 55amp
H22A1 - 65amp
H23A1 - 60amp

These are numbers from the repair manual and are engine dependent. It must be noted that on the prelude the ECM controls the alternator output current as a function of improving mileage.

Another thing to consider is whether the prelude alternator when put into the nsx system is spinning faster or slower then originally designed.

Excellent point... that never occurred to me. I should look into it.

Hi Steve, any updates on your rebuilt alternator? I should get mine sent in soon.

Hi everyone I recently bought a used Whipple kit with out alternator I am installing a 180 AMP high output alternator. I am not planning on installing a stereo system on my car either. My question would there be any difference in parasitic load using a high output alternator?

Anybody have the p/n for the CTSC alternator?

The wiki

shows: 31100-PT3-A52 RM. Which comes back to an 89-1993 Accord CJP16, RM = remanufactured
states: "1992-1996 Honda Prelude. which is a 31100-P14-A02, CJP78

(I suspect either that either that vintage Accord or Prelude will work as they have the same form factor)

I bought a 92-96 Prelude rewound (high amp) replacement. Worked great. Sorry, I didn't grab the part number
