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?
