Powermaster Alternator 140 Amp One-Wire V-Belt Pulley Smooth Look 1965-1973 is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Not a hiccup It's been around 7 months now and there hasn't been a single issue, the alternator looks great on the car and it's a simple install, regardless of how intimidating some potential buyers may feel doing the conversion, it really is simple stupid. Bottom line is; that it works and I expect it to work for a long time.

Rated 5 out of 5 by from Plenty of power to handle tech modern needs I upgraded from a 100 amp alternator that just wasn't cutting it on my recently completed 1969 Ford Mustang fastback restomod. I purchased the Powermaster natural finish alternator and it fits and looks great! It handles all my modern accessories with ease.

Powermaster Alternator 140 Amp One-Wire V-Belt Pulley Smooth Look 1965-1973 Video Transcript
By Bill Tumas: Bill: We have a special guest in the studio today. Brady, the Sales Manager from Powermaster, and he's here to tell us a little bit about their products. Brady, thanks for coming.

Brady: Thanks for having me, Bill.

Bill: What can you tell me about Powermaster?

Brady: Well, Powermaster Performance was started in 1981 making some OE parts. We do work for Richard Petty Driving School, Grave Digger monster trucks. In 1992, the Powermaster brand was started. What we do is high performance starters and alternators. We have a one-year warranty on our products and 90 days on some of the race stuff. We do a full refurb program for anybody that runs into a little trouble with an install or damages some products on a race vehicle.

We have everything from stock replacement alternators and starters all the way up to high performance gear reduction for engines up to 18 to one compression, alternators up to 200 and higher amperage. Basically anything for the street, strip and hot rod type applications.

Bill: Where are your products made at?

Brady: Everything we do is made in our 150,000-square foot plant in West Chicago, Illinois. We've been there since 1981 and we're not going anywhere.

Bill: I'm familiar with your starters and alternators, but I wasn't aware you guys made a generator.

Brady: Well, Bill, we actually don't. This is an alternator that just looks like a generator. This is for guys that are looking for a little bit higher amperage than the factory piece. We dyno test every starter and alternator that leaves the plant. Every alternator gets our proof of performance tag.

As you can see, this one did 90 amps at the top end, 72 at idle, which is well over three times the output a factory generator would've done. That's in half the weight of a factory generator package.

Bill: What can you tell me about this generator you brought with you?

Brady: What we brought with us today was the 200-amp in a natural finish here for upgrade on later model vehicles. We got a hundred amp one wire for a serpentine setup in a black finish. We also brought a chrome finish for the earlier models with the v-belt on it. That's again a one wire hundred amp hookup. Those come with the mounting hardware so that they'll bolt right into your Mustang. We offer anything from a stock replacement 60-amp externally regulated all the way up to that 200-amp of direct replacement.

Bill: They're all available in three finishes?

Brady: All available in not just these three finishes, but we also offer polished and a brand new satin finish that we're working on now.

Bill: Brady, I know starters are a big part of your business at Powermaster. Want can you tell us about this one you brought with you today?

Brady: This is our XS torque 200-foot pound starter. It's got a fully aluminum-encased solenoid and armature housing. What that does it helps keep heat soak down. The heat's going to dissipate right out of the starter motor during cranking. What it also has is our fully-adjustable intra-clock style feature. This starter can be rotated 360 degrees to clear headers and kick out an oil pan or really any obstacle you may have in the way, all in a package that will turn an engine up to 18 to one compression with no problems.

Bill: The Powermaster has taken a part that most people view as a replacement item and made it into a true performance necessity.

Brady: That's right. We've been making starters and alternators for your Mustang for over thirty years right here in the U.S.
