buschur racing posted years ago on why the buschur 20g came with a heavy clip. they measured backpressure at 80psi unclipped and 65psi clipped in 7cm. In addition FP has stated the 5h wheel only supports 47 lbs compressor flow. they also state clipping ruins efficiency of wheel. I wouldn't run 5h unless it was in 8cm 10cm or the twin scroll 12.5cm. but even then I would expect less than ideal results. even the standard 20 wheel deserves better than the 5h wheel. I estimate this billet wheel will flow 5lbs more than standard 20.
From what mts turbo service told me. The Tdo6sl2 has a lot of surging problems in small 7Cm housing. I'm not sure if this guy is creditable to believe or not
I wouldn't call the 6sl2 slightly bigger than the 5h. its 5mm larger ind and exd. It may be the best match for 20g wheel. but there's limited data on it and most are afraid to run it since its not a genuine mitsu wheel. EVO 8 guys are running 25g wheels on the 6sl2 and making well over 500whp with ease. so it clearly supports some flow. I have run the 20g many ways myself. only ran the 6sl2 in my evo x 12cm TS dsm setup. it spooled wonderfully fast and had manageable surge. like it wouldn't surge at 75% throttle but would at 100%. my favorite way to run 20g is with 6h/6cm combo. the 6h/7cm was a bit laggy for my tastes. (might be perfect with 60gram billet wheel) I also played with volute on 6cm and found it was quite easy to turn it into 7cm or worse. the buschur testing was done at 27psi if I remember correctly.
tempted to try billet 20g mated to this new 5h wheel I found. genuine mitsu updated 5h wheel. I think it would work well in the 12cm TS setup since the standard 5h mated to 71hta has done well in evo 8 turbos (475-490whp e85) problem is I don't want to try it without a ported shroud. there isn't yet a ported shroud for evo x 20g.
560tq and 440hp. But not on a td06.
2.4 with off the self 87mm wisco pistons.
20g with 6sl2 turbine.
e85
35ish psi, just unplugged the gate.
2g head with stock mani.
2g cams.
evo 8 intercooler.
I can't find my dyno sheet but i still have a video at the track.

Don't mean to revive an oldish thread.. But it seems like the correct thread for my question! I'm getting a 20g from turbo lab, it has a tdo6 compressor housing, 7cm turbine housing with a td06sl2 turbine. With this combo.. What do you think spool times and flow are going to be? I should also mention I'm getting a 7 blade billet wheel as well.
I'm aiming for 450 to 500hp... And I'm hoping this turbo could get me there (along with supporting mods)
By what folks are saying 450 wheel may be possible on a well prepped car, but id imagine 500 wheel is a stretch...
Should come on just before 4000 rpm.
Bolt it on and report back your trap speeds.....
^Why no TD06 comp housing?
