Pertronix 90amp alternator

[BFB]

Hell yeh, thats cool. Should start a thread on it so we can see more pics.

Back on the alternator subject, i have a buddy that recently bought out an old starter / alternator business and he said it no big deal to rebuild our old shit and even bump up an alternator to 90 amps.
If yall are interested i can see if he’d make a deal for doing a larger number of them vs onesies and twosies and maybe we can get together and ‘ buy in bulk’ for a discount

I just remember my sister's stock type 3 got pretty warm in the engine compartment. It did not effect the engine temperature though due to both the cooling air and the air cleaner pulled off the rear 1/4 side vents so they were isolated from all that compartment heat.

I see you have left off the firewall tin so air can come over the transaxle and into the fan housing. That is likely a big part of why it's working too.

I did a similar thing with my street Buggy when I changed over from a type 1 to a type 4 engine. I retained the crank mounted cooling fan but left off the firewall tin so the air free flows from under the car and out of the wheel wells over top the engine to fill that huge vacuum behind the car. I also moved the exhaust out to the sides and away from the center rear into the slipstream off the tires. The spent cooling air also exits the sides under the tappet covers instead of straight back.

The result of those changes created two hot spots behind the car to the left and right. The center rear down at the cooling fan intake is only a few degrees above ambient now. With the type 1 engine the hot spot was right behind the crank pulley dead center and as high as 3 feet above the road. At times it was as high as 40* above ambient! On and 80*F day it would be 120*F in the pulley/carb/air cleaner region.

Getting good air flow is not a simple thing on these rear engine cars!

Replacement alternator arrived on time. The old welded and balanced fan was showing it's age so I ordered some Zotz.
Fired it up. It's super quiet and puts out great power! So far so good!

Unfortunately you are more likely to get a bad “New out of the box” part than on the will work as advertised. Really sucks that this is the current norm.

Glad to hear you got this worked out.

Really hoping it didn’t take a month give or take for you to work through the warranty claim process and receive your replacement part.
