Anyone tried the Precision HP5857 Billet ball bearing turbo as thats meant to have spool as good as a GT3071r and the Power of a GT35?

Happily retired
That exactly corresponds to what Garrett themselves are claiming.
The way to get quicker spool with the new GTX is to go down a size while going up a technology, ie you replace your GT3076 with a GTX3071
The way to get more power with similar spool is to replace your turbo with the GTX equivalent, so in your case 42 for 42 but also a 3071 with a 3071 etc

The new borgs look great on paper too, but I havent tried one yet, and TBH I am unlikely to as im a bit of a garrett loyalist just in terms of the fact that they havent let me down and they do everything that I need to so no need for me to use something else really.
Plus TBH the ETT stuff is only really useful on bigger turbos anyway from I understand, and im not really interested in any engines much over 500bhp as I dont have a use for one personally as im into trackdays rather than top speed runs.

Out of interest would sort of extra strain would 3bar of boost put on components and gaskets compared to a lowly 2bar?
Also wouldnt the use of a 5 bar map sensor then be required to see use of this extra boost?

(but the same pressure should be seen for a little longer per cycle, hence more torque)

Cool. Any idea at what sort of presures it becomes necasary to start worrying about boost hoese popping off and running something more soild like wiggins clamps and the likes?
What sort of boost pressures and air volumes can modern WRC turbos produce (despite the inlet restrictions)?

as you said the wheels are different and the newer is a bit bigger [not a lot]
it might not sound much but it does make a difference
4x4 inducer is 46.6 and a t34 is 48.3 [exducer is bigger i know]
2wd is 44.6 there is quite a bit of difference in performance in these[iknow this is inducer but gives people an idea as the littel change can make difference]
what i would like to see is if the older cast wheels in the new design
to see what the comp map looks like
i know the hub [the bit where the comp nut sits] is smaller and you can run bigger tip lenght at the same inducer inlet size[turbonetics do this not sure on garrett]
i'd like to see more details and tec from garrett
if i had the money i think i'd go with the bw turbo just because there turbine shaft
[if only i had the money]

i can just see the new cossierich spec taking shape now. GTX3071 + spec r cooler then smash the 500bhp mark on a 'standard' engine 
then all you have to do is drive it!! 
pmsl
exactly. their website is like their turbo technology....... behind the times
dont get me wrong i've no doubt the gtx range will do what it says on the tin, but this is a delayed ( and now outdated ) attempt at keeping up with other companies turbo technology. for example the HTA compressor wheel for the 3076 has been around for a good few years now ( making 600bhp on pump fuel in the evo scene ). And the new BW EFR range just seems to wipe the floor with garrett with regards to the use of innovative new technologies. (and not just in wheel design either) I just think that garrett ( one of, if not THE biggest name in the turbo industry ) need to pull their finger out!

a pal of mine's just whacked one of these on his evo, dont know the exact full spec, but it made 607bhp on a standard inlet, and still a fairly rough map.... the thing was unreal, pulled like a train till well over double legal limits on a private highway!!!!
