Priming dry sumped ls3

[SOCAL 69 CAMARO]

First time writing so bare with me.
Just finished building my Dry sumped LS3. Got it to put out 608 horses and 535 lb torque. Pretty happy with it. What's getting under my skin is to think that to prime the motor I'm going to have to pull the belt and spin the pump with a drill motor. There's got to b a better way.
Looked into accumulators but the largest I found was 3 quarts. Would this b adequate as a priming solution?? Is 3 quarts enough??

Not cheap, but nice. Could always mount an accumulator.

Being that it was dynoed, why the concern for priming at this point?

I used a similar model http://motiveproducts.3dcartstores.com/1740-POWER-FILL-PRO-15-gallon_p_79.html Well worth the piece of mind to ensure the oil system is primed before start up.

Before the first couple of passes on the dyno I had to spin the pump with a drill to make sure everything was lubed. If it sat for more than a hour I had to spin the pump again in fear that if I didn't it would ruin the motor. That is when I had enough and started looking for a better solution.

Are you planning on priming the motor every time the car sits overnight? I'm with Donny... :dunno:

I only spin the pump if the engine has been idle more than two weeks or after an oil change of course. I have had dry sump engines now for about 10 years and no issue with this process.
I do use non synthetic 20-50wt oil because engine builder says it 'clings" better.

I like that Peterson pump. But I'll with/in the dark with the OP on the need to prime a dry sump every time. Is it observable on the oil gauge on a typical dry sump that it takes longer to first build pressure, or is that a dry sump just drains? a sitting engine much better, and therefore is a lot drier on start up, or something? It does seem like a hassle, and if say the 2 week time period was the cut-off, I could live with that, but every time, I'm with the OP and watching how this thread develops.

My current dry-sump LS7 was primed before its initial start. And never again, over about 50 oil changes. (I change oil before and after every track day).

My current customer dry-sump LS9 was primed before its initial start. And never again. Maybe I'm out of the loop, but I don't believe dry sumps require such priming.

I seriously doubt all those factory dry sump cars roaming the streets ever get any special priming after they leave the assembly line. I would just install an ignition interrupt switch that will allow you to crank the engine without starting until you have pressure on the gauge.

That's the conundrum, so do the factory motors have something special, like anti drain back, different/optimum elevations, etc, that we are overlooking, and therefore trying to compare apples to oranges? I don't know, and I am not excited to find out the expensive way. Priming Dry sumps has been the mantra for decades, was never really explained why, and now the tides have changed, and again no reasons really given for why the change.

I believe that factory sumped cars have electric pumps so as soon as u turn the key to power its pumping. The one I have is belt driven so I have to crank to get pressure. As far as the interrupt switch a good idea (my buddy mentioned that to me also) I just don't want to crank my engine for 15 seconds to get pressure. Maybe I'm just getting to dam picky

Thanks everyone for the food for thought. Keep it coming

Maybe I'm just getting to dam pickyI think you're trying to solve a problem that doesn't exist.

Can we have a parts list of pictures of your actual setup?
