Hi, I need to pick an alternator for my 31 Plymouth coupe Drag Week project.

It needs to be extra - reliable

Easy to find a bolt in replacement on the road trip
As light as possible

Enuff amps to run an MSD6 AL, electric fuel pump, all the lights in the car, and charge the little lightweight battery up fast if it gets run down

Any suggestions? Thanks Joel

I'm running a Denso 85A and it runs the Rampage fine
with some to spare... its your everyday production
alt found on many Chrysler cars... that way if you
dump one for any reason you can get one easy...
mine has been on the race car for 14 years now and
I have the same one on the Rampage... I had to change
pulleies since it comes with a multy cog belt... I
use a V belt... also I run more electrial stuff than you

The Mancini Denso ones run a little hot, but they pump up the voltage real nice, and I never had an issue with mine in the +3000 miles I put on my Hot rod with 4.56 gears! Nice, small, light, and +14vdc...

By the way, if its the car in your sig, that's got 4 headlights and draws 20 amps right there...

Mine`s a 60 amp denso for an 84 toyota 4-runner and has worked well for 4+ years running an elec. w/pump, fuel pump and fans but more amperage would make more sense.........

I use a GM CS130/140 amp alternator. Best thing is if my spare has problems any auto parts store will have one.

I've ran one of Andy's kits with the 60 amp Denso on the Valiant. Completed two drag weeks with it, no problems, 4 electric fans, electric fuel pump, MSD ignition.

Sorry op. Didn't want to hijack...

Yep same here. I use a 91 buick century I think when I ask for one.

Electric fan, water pump, and fuel pump, MSD Digital 6+ and it charges no problem even with a 5" crank pulley.

I use the stock mopar reg... here is the wiring
EDIT
The reason I use this is it puts out plenty and I
can change the reg if it goes bad... most times its
not the alt going bad but the reg so why change a
whole alt with the ones with the built in reg.. its
easy to full field the reg to find out whats bad
and its easier to change a reg

I use Denso....I have a 136 amp on my duster with 5.13 gears and never had any problems. Changed pulley to a v belt style and found that go kart spindle spacers work to shim pulley for alignment. Got mine brand new old stock on the Bay for $75....list for close to $400...application is from early to mid 90's pick ups....mine is externally regulated and I use the race regulator....some models are internally regulated from what I have seen....
