Yesterday I had the engine running and the lights on (all my lights are LED's). I used a clamp style ammeter to measure alternator output, and got about 28A. In theory, I could add another 52 amp load before maxing out the alternator. The 30A load of the e-PS should be well within the range of the alternator.

Although, now that I'm sitting here thinking about it, the fan wasn't running. I think I'll do that test again this week end.

The OEM donor fuel pump is about useless. There's really no way you can make that fit in the BDR fuel tank. Just toss it out and plan to purchase a new one.

My aluminum tank came with a larg'ish hole in the top of the tank, with surrounding screw holes. The hole is specifically designed for this particular fuel pump. Except for the small collector, it really is a simple bolt in. Like I said, get rid of the collector and use a Holley HydraMat. I used the high volume pump because of the supercharger.

You need to pull back the trunk carpeting and see what your fuel tank is set up for.

Thx bobcowan!

So what exact fuel pump would you go for when also using a HydraMat?

Would you think that a small 50a alternator would be enough for me then?

The coyote package comes with the fly by wire throttle. Do I have to mod it to make this work in the BD?
What kind of pedals (adjustable?) are you using anyway?

This is the alternator on my 2018 Gen 3 Coyote and the associated bracket. PBH Performance appears to have some useful items for these swaps.

You can use a HydraMat with just about any pump. I have one in my race car, with an aftermarket pump on a Miata hanger, and in a Miata fuel tank. It's awesome. I can run the tank nearly bone dry before it starts to sputter in the corners. It really is everything they say it is.

Would a 50A alternator work? Yeah, I think it would, as long as you pay attention to the electrical components you install. But then I don't think you'll be making enough power to use e-PS. And if you really run the battery low, I think it would take a while to recharge.

I installed the 80A because it satisfies my OCD. 50A is probably enough? But 80A helps me sleep better at night. I like to have extra capacity that I may never need. It makes me happy.

As for the throttle, I just bolted the stock pedal to the firewall and plugged it in. I'll try to remember to take a pic for ya.

The BDR comes with gas pedal, brake pedal, and clutch pedal already installed. They are all on one long bolt. BEFORE you install the motor, pull that long bolt out and set up the pedals the way you want them. If the engine is installed, you'll never get that bolt out.

Additionally, the fly by wire gas pedal makes it really easy to install cruise control. When you get to that point, let me know.
