I was wondering the same thing about that charger. According to borgwarner match bot it would do 750hp at the flywheel on 12 psi in the 1.05 ar turbine housing on a 5.3. So figure a rough 20% drive line loss thats 600 tire on 12 psi.
I thought OLD GOLD with the olive green 5.3 swapped 280z had a billet S366. Thought he made around 650 at 18lbs. Same guy that bought Denmah's old fairmont. I'll see if I can find it.

I was wrong... 540 RWHP on 11 psi

I swapped from a pair of Turbonetics Tseries Billet 7568s with .81AR to the Borg SXE 369s with 73mm turbine and 88AR. Power was down 200hp and spool went to crap. The netics would be all in at 4600rpm and the borgs werent all in till 6200. I swapped cams and changed stators a few times. I finally put the Turbonetics back on and power/spool was back. I later swapped to a pair of precisions and picked up over the netics. You couldn't pay me to try any of the SXE369s ever again. Testing was done up to 26psi. This was all done about 10 months ago.

I've been looking at Quick-silvers 3200lb s10 going 5.0's @ 140 in the 1/8th with a 6.0 and cast 66's running out of injector. Thinks it will go faster with more fuel.

What size engine etc ?
Out of interest too...despite the AR numbers, how did the actual hole inside the turbine housing look ? The 0.88's on my 364's the hole looks really small. I got a pair of AGP 0.96 housings to try and the hole inside the scroll is massive by comparison. I had no pressure issues...just that small hole always annoyed me lol so will change them and see
What Precisions did you move to ?
Great info, thanks. Never hear much about the new SXE line on the V8's. What kind of times were you running? weight?

Is that 75mm the inducer size of the Turbonetics ? Bigger compressor, you'd expect more power, although the spool is maybe surprising.

The engine is a alum 5.3 with Tooley TFS 220 heads and Cam. Andreas Cooper ring gaskets and 1/2" head studs. Wiseco pistons and Callies rods. PTC 10 clutch glide with a 15-40 stator. The Holley 160# injectors are at 75psi and are rated to 221# with a belt driven pump. IDC is 95%. I run a dominator setup and at 34psi AFR is 11.3 and 15* of timing at 7800rpm. The engine combo has been together since 2012 with minor changes here and there

I run 4" downpipes with a 3"-4" transition that is 1.5" long. The precisions are the CEA 6766s with .81AR. So far Ive had it up to 34psi and its still making power.

And quite surprising too....seemingly the smallest turbos, are making the most power ? I wonder is it a case of them being a better overall unit...or it just so happened a better match to the engine itself ?

That's only a comparison between an old Precision and the "new", although even those are a few years old now
There really isnt a lot of difference between the new 66mm Precision turbine wheel and 68mm BW turbine wheel on the likes of my 364FMW which would be same as the 68mm SXE wheel.
I assume the 73mm SXE would also be comparable although I havent seen one myself
Likewise, the compressor wheel in my 364 is almost identical to a 6466CEA2. So it's hard to follow that the power difference might be from that alone.
The TN turbine wheel may well be very different, but still very surprising results. Not too often people would try so many units though and actually get results though.
