Default Re: Alternator upgrade

When Marc did the alternator upgrade on my car to 200 amp he also did the double wire to the AC blower. Before the mod air flow out my vent was at 10 mph and after it was 14 mph. I like it very much. Just spent 3 hours in Dhaka, Bangladesh traffic with no AC and can't wait to get home next week!

Hey Charlie! I added additional 18 ga. wire from the battery to the HVAC controller and fan's performance improved a lot also.

The additional wiring is a great idea. I'll have to remember that.

Default Re: Alternator upgrade

what is the benefit of this one vs the CS-144 from Power Master?

Hairpin alternators are suppose to produce higher amp at idle compared to conventional. Also, suppose to perform better at high temperature such as hot day, underhood condition.
Above are based on what I have read. Not been able to confirm so far.

How is this holding up? been thinking about this again.. I noticed it mainly at idle. I have a couple ideas to try.. before dropping money on one of these.. Group buy never panned out.. nobody was interested. I think if I buy one, the stock power is fine, I just want better idle current

It's holding up fine. Last week in DC area was between 96 to 103 degrees. I never found myself in major traffic back up (a disappointment!) but evening commute meant about 15 minutes of bumper to bumper.
With Spal fans running at full speed, maximum coolant temp I saw was 211. Once it hit 211, temp started to come down and around 200-201 would go up to 208 and repeat. With fans running, voltage readout was 14.3 to 14.5 volts. Oil temp was steady at 197 but occasionally would go up to 201 to 202.
Dewitt dual core, 200 amp alternator and Spal fans definitely reeled in coolant temp concern in worst case scenario.
It would be interesting to compare voltage reading of stock 94 Z with OEM fans running vs. my setup, although not apple to apple.
