"vacuum gauge" to balance stacks?

Hi Rick,

Does the alternator fit an FE without using different mounts? I searched, but could never find anything that wasn't too deep.

TO you guys running Alpha-N on an FE.

How have you got your A/F ratios set up? I'm mostly at a 13.5. I have stage 3 heads. I understand that these motors like to run rich.

kobrabytes Len I have my Alt on the L/S on my engine up at the top just below my outlet and upper radiator hose on my car. The reason was because of room being tight from the blower and my P/S pump is on the lower R/S mounted to the timing cover bottom 2 bolt holes. My timing cover is one that works with a solid motor plate and mounts to the frame rails. The correct ERA way is that it mounts on the R/S of the motor in a higher location. Except for my Alt being a little short in max output (70a) it has worked fine for 11 years. I am going to a bigger 120-130a because of charging issues when racing. Too much draw with the added pumps and fans. Rick L. Ps the Amp gauge and wiring through it must be changed to a Volt gauge. The old gauges where only set to handle 60 amps with spikes in the 90's for a short time.

Hi Len,

I am using a 100A alternator onto my ERA/FE. This did take some modification to get it to work but they were not difficult. To begin with, I am using a set of March 2-V (groove) pulleys which puskes the belt about a 1/2" further from the motor than a 1-V pulley set would. I then used a single groove pulley on my alternator and used a combination of ERA's FE alternator mount kit with a custom set of spacers and water pump bracket (I have a shelby pump which did not fit the original ERA support bracket) to get everything to line up using the outer of the two grooves on the crank and water pump pulleys. I machined the back (unused) groove off the water pump pulley for appearance reasons. LAst step was to go the the local auto parts store, buy 2-3 belts that were close to the right side, and find a belt that would fit the best. The whole setup fits and works great. Here's a picture of the end result:



Here's a picture of the setup with the engine out of the car. I switched from the bracket shown in this picture to the ERA version because the alternator need to be further from the engine to fit ERA's chassis.



I hope this helps.

THanks Fred, nice setup!
