Last "all out" runs (ran my current best of 9.32@147) I made were back in February, about 3 weeks before losing my job...I'm a fleet mechanic by trade, so no issue getting right back to work...just issue with new job being 43 miles away, one way, which blows with $5/gallon gas, and a pickup truck as my daily...
Haven't really been "into it" since, to be quite honest, and have only been to 2 bracket races, with power turned down, so as not to break something I don't want to fix...lol.
My son just swapped on a billet 80 onto the LS Mustang we built, and he's quite happy with it...and following his lead, I ordered one for myself. My hope is it makes more power with less boost/backpressure, which I believe it "should"...
Best ET was 9.32 and best MPH was 148...and it seemed like the 78/75 was simply done at that point, on my 6.0. I'm still plenty happy with how it ran, in a 4120# car, running through a 4 foot long, 3" downpipe. New turbo will initially be ran with my short 4" downpipe, then a fender exit...
Baaahhhhhhh you caved lol.
I would have caved a while ago so no judgement here.
That new turbo can only make you go faster, 8.99 is definitely a real possibility and a good call for not wanting to redo the whole hotside.
What do you wanna bet you'll have to throw significantly more fuel at it?

Lol, yeah I finally caved in...
I agree, it'll be interesting to see how fueling demand changes. I've never seen higher than 55% IDC, so I should have plenty of reserve.

Hey slow, does anyone have results switching to that one, you dont see much in the way of reviews. Not to hijack rel3rd's post.
I had that turbo for a bit before selling it back in early 2020, it picked up fuel usage over the 7875 Next Gen I had been running with the 1.24 housing in late 2019. I can see it putting down ~950whp on a 5.3L so probably 100hp or so more than a maxed out 7875. I think OP said he was around 800whp at some point so he should realize some gains.
Not sure if they have changed the wheel since then but these were the specs on mine which look similar to what rel3rd posted:
This is our new release Billet 80mm mated to our 87×82 Turbine in 1.10 t4 Divided housing

I switched from a next gen 7875 with the 1.25 housing to that one but don't have any data that can be used. I made the switch because I have a 370 and didn't like how the 7875 came on too hard and too fast, especially. I'm only running 235 DRs and it was downright dangerous on the street. Never ran the 7875 on the track, so no track data. The 80mm definitely feels like it pulls harder and rolls into boost much smoother. But, again, this is a 370 not a 5.3. I've had 3 track outings with the 80mm, but no useful data. First full pass it went 9.42 @ only 143+ with crazy converter slip. Went 50/50 mix with HD John Deere Hygard fluid and that seemed to have reduced the slip a little. However, 2nd time out I blew the new style IAT and grommet out the uppipe leaving a 9/16" hole and making a very effective WG, LOL. Next time out the banjo fitting came loose and fell out and again, there went all the boost. So far it's looking like I'll have to run a little more boost to make up the power lost with the slip. The launch is exactly as I want it...controlled. 1.404 so far.
If I was looking to upgrade with a 6.0L but still stay T4, I would go with the 80mm with the 96mm wheel. However, I have to say Rel3rd has gotten way more out of his small 7875 than I could have imagined.
I honestly didn't think it (the 78/75) would have did as good as it did either.
My car also has a 6.0 liter, just to clarify.
There are a ridiculous amount of choices in turbos, just from that 1 vendor, but I "think" the one I bought is the biggest that still uses slip fit for the compressor to intercooler piping connection?
It's supposed to be here tomorrow, so I hope to have it on by the weekend.
My only possible, (that I foresee), setback, is if it doesn't clear my radiator. I can stand mine up a tad more, but it's about as stood up as a stocker can be.
I have a 80/96 slip fit I ran on a lq9. I ran a faster e.t with my 7875 at similar boost levels. The biggest difference I noticed was IATs was less with the 80mm. I'm sure if I ran more boost the 80 would have done better overall

Hmm. Interesting. How much boost were you running and what was the hot side setup?

Indeed a lot of choices on the market! You can get a 94mm in slip fit outlet if you want to. Even a lot of the vband outlet compressors allow you to cut the vband off and use a barb for silicone coupler behind it, something like this:
VSR has the 80 87/82 in a v clamp, like the one you pic'ed, but close to $100 more-I like the v clamp only because I can get a tight bend if needed in steel. Also has the option of cutting it off, still have a rib. Prob get the one 3RD is getting once he approves it, lol.

LOL. No pressure, right?
It arrived today, and plan was to put the car on ramps, yank the radiator, and figure out if I'd have to do a stand up radiator or not...one thing led to another and, new turbo is on, clears stock radiator fine, and needed very little "adjustments" to bolt on. In fact, only one tweak, which was loosen some intercooler connections...
I can say this, with 100% sincerity...I'll never again own a turbo that isn't v banded together like this new one is. Soooooo, much easier, to bolt turbine housing on by itself, then center section, then compressor housing section. Did 95% of the swap from under the hood.
I get up at 2:15am for work, so decided to quit at 8:30pm, but did fire it up, for no reason whatsoever, lol.
All that is left is downpipe and refilling radiator and checking for leaks and whatnot.
With the On3 hotside, I have roughly 3/4" clearance between rad and turbine housing, and 1"+ between compressor housing and rad.
Was sweating my a$$ off, so pics will be taken another day, before completion.
Congrats on the install! Looking forward to seeing how she performs. I have the VSRacing S480 w/billet wheel, 1.32 A/R, 102/92 T6 Turbine and while I don't have a good pass to report (having to upgrade my twin 340s to Twin Hellcat pumps), I really love the bits of highway romps , just flooring it at 45mph and feeling that rush of acceleration. It feels stronger that my prior turbo incarnations and is much more manageable off the line than the twin turbo (GT35"S) I'd had before.

Finally retiring the NextGen 78/75
