I have blown up two cars on offramps on the street with enough oil and no accusump. I think the SLC can pull plenty of g's and can starve if right. I have a street SLC and have an accusump. For like $300-400 total cost it is worth it. I just use a standard lever and leave it on all the time and only turn it off to check oil level. That is how some of the race cars teams that use them do it to keep it simple and saves money.
Personally I would love to see the same exact engine with an accusump or nothing and then a dry sump and see if it actually makes more hp. I am thinking it would not make more overall. Sure, the windage would be better, but the parastaic loss from the pump has to be huge with running 3-5 pumps at once with higher volumes and pressure. I just do not see the engine making up that much power, but I could be wrong. Then the added weight of the entire system with all the lines, tanks and tons of oil I just do not see it. By the time you are done you would have spent like 4-5K or more with the dry sump system, oil pan, an fittings, hoses and other fab items. I have built and ran a drysump on an engine and it worked good, good pressure all the time and no issues. I also now run an accusump and no issues on engines again but at 1/10th the cost and time. Same end goal, save engine and have fun.
Also, the accusmp is really a bit of an oil cooler. As you are off throttle the pressure is lower so it pumps oil into the engine, when revs come up pressure comes up and oil into the accusump. So it is really moving oil most of the time and it does get hot so it can disapate heat. Now where you have it located that may or may not be a good thing, but you can wrap it or flow air over it to solve that a bit. I will also be running and oil cooler so not really an issue for me, just more food for thought.
