SC61 compressor map...???
the SC61 runs a 61mm inducer 82mm exducer GT40 56trim compressor wheel correct?
or is it 50 or 54 trim?
anyone have any compressor maps?
ill be running with an 1845cc bottom end, and after ploting the turbine configuration ( t350 stage V turbine wheel in 4bolt T3 .63 a/r exhaust housing) in reference to the compressor setup i am interested in, the map seems to check out very nicely...
i have the option to run the Innovative GT61 61mm inducer 86mm exducer compressor wheel in a .70a/r compressor cover or the GTS61 compressor, which consists of the the same wheel as the sc61 (61mm inducer 82mm exducer GT40 compressor wheel)
so after crunching turbine numbers to determine spooling characteristics and all the other BS associated with Properly plotting a compressor map here is what i came up with.
now i would like to compare this to the exact GTS61 or SC61 wheel.
seeing as the major on the standard gt61 wheel is bigger by about 4mm larger than the gt40 (sc61) major the 61mm minor will spin at more revolutions per min. at a lesser major rpm resulting in faster spool up. (this all brought to my attention by terry Jenkins at innovative turbo systems.)
so some personal opinions please...
will the gt40 82mm SC61 wheel induce more lag(providing that the turbine configurations on both turbos are identical)?
and does anyone have any proof of its efficiency??? i know its a claimed 80% and above. but does anyone have solid evidence?
and would anyone with a compressor map plotted or not come foward with it please...
Thanks for your time.

The only way to prove this is by datalogging four different fast acting sensors (turbo inlet temp and pressure, turbo outlet temp and pressure) and then figuring the compressor efficiency from that. I highly doubt anyone has done that.
Otherwise, I think you have all of the information you need really. I would use the smaller of the two wheels.

Re: SC61 compressor map...??? (GT61 this 1.8t)
The GTS61 from Innovative uses a Garrett T61 and not the GT40 56 trim like used in the SC61. But innovative's GT35S61 does have the GT40 56 trim from Garrett that is also used in the SC61, GT35R, GT35S, GT35e from Precision.
The difference between the GT40 56 trim and T61 is almost nothing, but the GT40 56 trim is about 4% more effcient.

Very good point. I just hooked up my exhaust manifold pressure sensor today. Getting some pretty cool data logs for my personal reference.

Re: SC61 compressor map...??? (kpt4321)
so the gt40 82mm wheel??
hmmm
also im trying to talk terry at ITS into throwing the GTS61 on a hot gas machine to map out the compressor... costs some $$$ tho... if so ill post the info asap...
i was also thinking the 82mm wheel... basicly less rotating mass, but the wheel has to work harder to spin the minor wheel(61mm inducer) resulting in less air being drawn in at any given RPM...
make sense?
thats why im almost dead set on the larger wheel...
just dont want to set it in stone until i get some solid proof of which is better...
this will be a full ceramic dual Ball Bearing unit and all stops taken out...
going all out.
so its either GT61/GT30R with the 76trim or 84 trim GT turbine wheel
GT61/t3 stage V .63a/r
or the GTS61 GT40 50trim compressor wheel, with the T3 style .63 a/r stage V turbine section.
those are the three that are up in the air... and ive got one mapped out...

im a dealer for ITS and i can assure you the GTS61 runs with a gt40 wheel in 50trim, 54trim or 56trim option. not the t61 wheel.

Re: SC61 compressor map...??? (GT61 this 1.8t)
My sources from Garret R&D say stick to the GT40 56 trim compressor, 84 trim GT turbine wheel. 
Anymore info and I am accused of being biased.

LOL
i know how that is!!
however notice this wont be reving to 9k...
so the 84trim could do some damage ...
on my old setup i ran the GTS61 from ITS and made 441wheel.
just want to run the .70a/r compressor.
and try alittle somthin somthin different ya know?
and also i found a map and plotted it...
the GT40 50 and 54 trim...
enjoy.
also i know the boost curve is not linear like it is represented in this plot... but to keep it simple and to give me the ball park figure(time being the reason its not completely Plotted) ...
maybe this will help some of you b18 guys out...
based on 1845cc.

Is there a difference between the GTS61 and GT61? According to Innovative's catalog the GT61 uses 2.4" inducer 3.540" exducer and the GT40 56 Trim has a 2.416"inducer/ 3.227" exducer. Its not off the street, its right out of their catalog.

the gts61 is their version of precisions sc61...
supose to be the same specs.
gt wheel, 50trim, 54 trim or 56trim stuffed in a t04e cover.
the gt61 and gts61 are two totally different turbos.
im down with staying with the gts61... it will be cheaper for me... i just dont like the way the compressor plots out ya know?

Makes sense. So GT61=T61, GTS61= GT40 56 trim....Thanks for making that clear. I think some vendors call the GTS61 a GT35S61 I guess since the GT40 56 trim is used in the GT35R from Garrett and that is the compressor wheel they use?

haha...
your over a 1/4 of the way there my friend...
next dyno session???
and art, the answer to your last question is yes.
the gts61 is the unguided GT61/35S or what ever the hell some call it...
but flat out its called the GTS61... or we can call it an SC61 by ITS.

Re: SC61 compressor map...??? (GT61 this 1.8t)
well i hope this thred digs deeper for those stuck with the decision of ITS or precision....
and open up some eyes....
basicly gts61 from ITS is = to Precision SC61.
and now i found a map... donno how accurate it is. its an official garrett map so.

I dont think you should put too much into those maps.
If they are from the same source they are good for comparing,
but I think chosing turbo all out from how the compressormaps plots come out is a long shot, at best.
The turbocharger you put on the engine, and the spool-caracteristics on this turbo will change the VE of the engine as it spools, and for sure change the VE in the top rpms. A GT35 turbinewheel will probably give the a tad better efficiency than the stage V wheel, and it will probably even give less backpressure too...
To take an example, on the VAG 1.8T (like other engines) the cams you chose will very much affect how the turbo spools and the VE on the engine... If you chose the right cams you can get a bigass turbo to spool even faster, at the cost of some lost top-end.

I think the GT40 56trim and an 84 GT turbin would be great too!
Put it in a .63ar t3 housing and a t04e or t04s housing and you have a bad-*** turbocharger!
This will be for sure be a really efficent turbo!
I think this would spool great on a 1845cc VAG 1.8T...
would probably give more power than the ITS gts61, AND give faster spool...
I do not wish too come out as a oracle that knows everything. I really dont have any hard evidence! These are my personal opinions and beliefs...

hey man... thats why i posted this thread... for input...
all input is appreciated...
i just ploted the gt61 wheel with the stage 5 T3 wheel in mind... and figured my VE by RPM...
i like the 56 trim gt40 wheel...
and i like the 84trim GT turbine wheel.
id love to go with a GTS61 from ITS with the GT40 56trim wheel, and a .70a/r housing, and the 84trim GT wheel in a T3 .63 a/r housing...
but i change my mind on eveyrthing...
im just looking to make 550whp with a 7600rpm redline.
and spool to 25psi around 5200...
also i will be running a dual ceramic ball bearing center section.
I dont think you should put too much into those maps.
If they are from the same source they are good for comparing,
but I think chosing turbo all out from how the compressormaps plots come out is a long shot, at best.
The turbocharger you put on the engine, and the spool-caracteristics on this turbo will change the VE of the engine as it spools, and for sure change the VE in the top rpms. A GT35 turbinewheel will probably give the a tad better efficiency than the stage V wheel, and it will probably even give less backpressure too...
To take an example, on the VAG 1.8T (like other engines) the cams you chose will very much affect how the turbo spools and the VE on the engine... If you chose the right cams you can get a bigass turbo to spool even faster, at the cost of some lost top-end.
I think the GT40 56trim and an 84 GT turbin would be great too!
Put it in a .63ar t3 housing and a t04e or t04s housing and you have a bad-*** turbocharger!
This will be for sure be a really efficent turbo!
I think this would spool great on a 1845cc VAG 1.8T...
would probably give more power than the ITS gts61, AND give faster spool...
I do not wish too come out as a oracle that knows everything. I really dont have any hard evidence! These are my personal opinions and beliefs...</TD></TR></TABLE>

Dude, we are very much in the same boat. And yes, input is great
My goals are much the same as yours, only less extreme.
I'm going with an 2.0 VAG (abf-block), with the 20v head, and I'll stay below 7600 too...
And I planned on running the engine daily with about 380whp...
I guess I aim for more driveability than you too and I hope to see 25psi at 4500rpm...
The GTS61 from ITS with the GT40 56trim wheel, and a .70a/r housing is a great idea. I dont know how much the .70ar housing will do over the .60 though...
So I guess I'll go with a .60
To reach 550whp you'll proably need every little bit extra you can get thoug.
A gt61 might give you more power, but it will probably also give more lag over the other I think... 5000 to 7600 is a short powerband indeed...
Its your choice.
Either way will give big power and be a real badboy!

Re: SC61 compressor map...??? (MrBond)
BTW...
I guess were a bit "on the wrong forum"...
But the honda-guys are so far ahead of us VAG-guys when it comes to big-turbos...
Good to get some input from people with actual experience

Re: SC61 compressor map...??? (MrBond)
Steve/GT61 this 1.8t, did you try plotting into this compressormap for the "sc61" compressor...
in my eyes that seem to be even better than the GT61...
It would be 3-4% more efficient overall...
You might be correct that the gt61 wheel (weird enough) will spool a tad earlier, but I'm not 100% sure on that one...
But those extra % of efficiency can't be too bad.
Are you positive that you will actually make 11.5psi @ 4k with the 1845cc ?
Thats calculated with a t350 stage V turbine in T3 .63 a/r ?
What cams will you be running. I've understood you stick with hydro lifters, but your going with some cams that will improve midrange/spool, or maybe even topend, I guess?

hey guys! i also have a VAG 20v... AWP short block AEB head. 2L now tho.
8:1 cr.
anyways i'm also in the business of picking a turbo and was considering the sc61 as well. I was going to go with a straight gt30r, then i thought ok well gt35r now i'm thinking sc series for budget reasons.
you think we'll hit 11 psi @ 4k???? thats a big turbo.

yeah i read that post... lots of flaming as always on the tex.
fuel management i'm probably going to run one of the more affordable full standalones. This motor is going into an a2 so it is a total swap and i didn't buy the oem ecu / harness.
It will probably be either perfect power, sds, or something along those lines. single stage of big injectors 700-800cc.
car will have a short runner too though because i didn't get an oem intake manifold. Guess i'm just gonna run a rustang t-body and tps.
