Hollywood / AMS 750R / E85 / dump tube build
Nice results.
If I notice correctly, although peak boost for the black was a bit higher, from 4400rpm to 6000rpm the black is about 1 psi less, and after 6000rpm the difference starts to increase, as by 7000rpm there is a 2 psi difference, at 7200rpm (peak power) about 3 psi difference and at 8000rpm 4psi difference. I believe the results would have been closer if you could get the boost on the black to match the one on the 750 kit all the way, especially that the black at 25psi (boost at peak power) is not well into its efficiency range.

This was true on the 8/9, but we don't know yet on the X. Thus far, no one has been able to get the black to hold much over 24psi at redline. Kinda sucks, and eventually we will figure it out. I think the wga that comes with it sucks, and there's really not a good aftermarket option. The HKS is 22psi, but we really need a wga with about 25 or more base pressure like the 8/9 has to even have a chance to hold higher boost up top.
Nice results.

I think we need a 25psi actuator like the 8/9 had...even my blouch seems to be the culprit. For how linear this is you can tell its just the actuator sucking and not being able to withstand the back pressure.
If you look how it drops compared to any of the stock housing turbos it's just inevitable. The stock housing is just small and hits a wall then starts to taper, all of them do it around the same point. Like I said even on mine with everything open and the ability to breath more it lost power trying to hold more, it just works too hard and gets too hot.
Looks pretty badass man! What are you using for boost control, just a MBC? Your black tapers worse than my BBX...of course you have a 2.3L so that explains a lot.
Looks like a good solid setup....sounds like the oil-only turbos are pretty reliable says AMS, that's pretty surprising, but awesome!
Enjoy the setup man, looks like fun!

hey Hollywood - can you tell me more about the hotside connection? what diameter is that hose? what does it bolt upto? I assume it would bolt upto stock? or the Depo Racing UICP?
It's a large V-band for the down pipe and dump tube, what are you looking for exactly?
The intake hose is 4" x 3.5" and the intake itself is the same size ans the Primo and MAP.
Every thing is Vband and included with the kit.
Yep
