Then what does it do? Duel pass made my sand rig feel crisp. I was thinking it was pulling timing but after the duel pass it pulls hard the whole time. Come to think of it it did take quite a while to start bogging but on the street you can't stay in it near as much unless you are in the mountains. It really was a nice improvement on a long run. I have no idea why.

 

I have run a dual pass and a single pass the only difference I saw was how fast it cooled down it cooled down a little faster but no wow faster what has made a difference is adding capacity to the system if your going to do any thing the option b which constantly bleeds the system is the best bet

 

A big front mount H/E also adds capacity. As does option B relative to the stock system. Everything helps, and there's no point in trying to make a ton of power on the stock setup, IAT's will be through the roof all the time.

 

option b dose not add capacity once system is bled

 

That full-size tank and hoses surely contain more fluid than the little filler.

I know you are talking about what cycles through the cores though, just showing my side of the argument
