360 uses a 68mm turbine and 366 has a 73mm turbine. Their are plenty of options between those two to fit just about any need...

Anyone tested the difference in spool between a cast 72/83 .9 and the fleece s467? I've heard people like the fleece s467 but if it's not much difference in spool than I should go smaller like a 366 or vgt. I won't be towing all the time but I would like to have the option. My wife and I want to get a toy hauler in the future.
I'm not sure break boosting is a great indication of turbo spool up
It's all around the same spool up weather I'm staging or street driving. My converter is stock stall as well.
triple 366s work fine and tow/DD great. How you size depends on if you want the kit to be optimized for towing/DD (so a smaller than ideal HP turbo) or optimized for the top end but deal with some more lag. I would ask yourself what percentage of the time you will be running the truck above 1000 HP to help you decide.
A pair of 366 will give you enough air for about anything that can be a true DD, my dual fuelers and 60 over sticks are a joke for them. Really they need 100 or 120 overs to use up the air. I doubt 120 over sticks would even haze that much on the top end. I have 0 spool issues either. I do like the idea of going with a 400 charger in the valley just for durability, but I just don't see the need for anything bigger than a 2x366 over a 472 in anything less than a dedicated competition truck.

This is why I think a 467 with 360s or even a 366 in valley would be better for my needs. The truck is my hot rod but not a dedicated race truck and I would like to be able to tow stuff. 1000 hp would be cool but I wouldn't like the lag not to mention the cost of fixing broken components.
I think you would be very happy with a 467 in the valley with 362-366 size twins. I have 0 issues getting on top of the twin 366s even with a 650HP tow tune and normal driving. If you decide you want to turn it up with a twin 366/467 you could spray a little bit between stages and reduce the choke of the 467 compressor, but I wouldn't think you would have to do that until the 1200 HP range. Just make sure whatever setup you go with has enough waste gate to keep the drive pressure under control for the HP turbo.
I think I will try to go with s472 and s366's. Capable of what I want to achieve and room to grow. I will try to throw in some bigger injectors when I do this. What size wastegate are people using to go around the valley charger? And is one to go around the s300's needed as well?
I'm working on that exact setup for my truck now... What turbine wheels are you going to be using? I'm hoping to be doing some testing with the setup, hoping to find a few different turbo combinations that work well together.
I have no idea yet lol. That going to be next on the list to figure out I guess. Let us know how it turns out for you.
I don't see a real need for wastegates on the primaries unless you were doing something crazy like a lot of spray. The valley turbo is already taking some energy out of the flow and it would take a crazy amount of fueling to overwhelm the twin 366s.
When WOP ran triples on their 7.3 race truck, thy were all the same s300 frame turbo. Had a big 60mm gate on the pedestal and the atmos weren't gated. That truck made 120-psi on fuel at under 1:1 drive pressure and 148-psi on spray, still at 1:1.

i have a epr triple setup with 3 billet s366 for 3g.... a customer of mine bought a lbz with the setup on it and running like crap.. long story short i put a stock engine in it and traded him labor for the triples and built engine with intents of putting them on my truck. But they have just been setting around and i could use the money. The guy that installed the setup wasn't the brightest and broke a ear off the one turbo drain flange other than that i have everything minus some bolts and gaskets
