Found out exactly what turbo i have..

[turbo535]

I have a garrett hybrid t3-t04E with the 4" wide dual throat housing. I have the non wastegate turbine housing with a 3 inch ring flange
I think this is just about the biggest of its class. Supposedly can handle 500 or more hp. It spools up super fast (even just rev-ing). Is there anything more that can be done to get more out of this turbo?? what about clipping the turbine blades?? what gains do you get from that? I think two of these on my motor would make some serious power

[wankelnut]

i have never seen a t3-4 turbo make more than 400 hp and that was on a small displacement motor.. the turbine side (t3 part) will choke the motor limiting the hp... clipping the turbine wheel will reduce backpressure but you will have alot more turbo lag..
i would use a full t4 turbo with a 60mm comp wheel, with an 81open or a 70 split turbine housing, p trim turbine wheel... lots of power at low boost, quick spool up and lots of room for more power when you build the motor

:lol :lol :lol

thats like 350 at the flywheel isn't it. that was at only 9 psi because of weak wastegate spring. I know the turbo is good for up to 25 psi. Won't the wastegate let out enough exhaust at high rpm to not choke the motor but still allow the turbo to boost. what turbo would be best and still have the super low rpm spool like the hybrid

I've seen a 60 trim T3/T04E Stg3 wheel, 0.82 A/R housing make 450rwhp, which is probably about all it had.

[Def]

BTW - I don't think you have a T3/T04E - I think you have a straight T4 turbo.

The only divided inlet T3 turbines that I know of are 0.78 A/R GT series stuff that's custom made very recently(i.e. expensive). T4 turbines are routinely divided.

[turbo535]

it has a v band 3 inch outlet though which is not that common. It is the to4E stage 3 at least. I forget the AR but i think it is .82 Next time i have it off i will take pics.

:rofl

I believe ShawnM had a t3/t4 HiFi 60-1 with either .68 a/r or .82 a/r making 545.7whp-582trq.jpg!!!!!!!!!!!!!

He did 11.115 @ 129 MPH 1.7 60' in the 1/4 mile!!!!!!!!

beings that its still the first month of the year i think that is to date first dumbest (sp) <lol thing ive find

[Def]

Uhhhh... alright, sounds like you have no idea what you're describing. Have fun with that T4.

[turbo535]

the compressor housing is called a dual throat, you will see when i get pics. the exhaust is not divided which is what i thought you were talking about

it is not a common compressor housing. This turbo is really old like maybe 5 years.

[Def]

You mean a PORTED SHROUD compressor inlet? Commonly called an anti-surge housing.

You need to specify which housing and if it's the inlet or outlet when describing it.

You don't want to clip turbine blades. You'll kill spool just for a little more top end spool.

Let me get this straight:
-T3 turbine housing with 3" v-band outlet(supposedly pretty rare)
-.82 a/r turbine housing
-So the dual throat inlet you were talking about is the compressor housing
not the turbine housing.

So by dual throat, do you mean one with a surge protector like a GT30R? If it is a 4" inlet it is a TO4S not a TO4E.

Oh brother! :rolleyes

[turbo535]

ok the compressor housing looks like this
www mjmturbos. com dualthroat. htm
ignor the rest of the turbo
take it easy on me guys i am not trying to make it seem like i don't know what i am talking about.
It would be easy if i could say i have a gt35 turbo but i bought my turbo from a friend a long time ago and never really have known what it is or better how to explain it until i found the site above with all the pics and stuff. At least i am getting feed back on what is possible to get out of it.

i believe ShawnM had a t3/t4 HiFi 60-1 with either .68 a/r or .82 a/r making 545.7whp-582trq.jpg!!!!!!!!

OK i am talking about the inlet which is 4" the outlet is 2.5

look at pic

[russelcq]

Man,
That pic you posted is a small as turbine housing. If you have the turbo, use it. See what you get out of it. If it dosesn't suit your needs, upgrade?

Here is the link (www.mjmturbos.com/dualthroat.htm) to help you out.

It's looking like we know what we are talking about.

Def: You mean a PORTED SHROUD compressor inlet? Commonly called an anti-surge housing.
He and I had it right, making it a 4" inlet making it a TO4S typically...not a TO4E.

The pic doesn't have a 3" v-band flange on the housing...yours does?

[Def]

T04S housings aren't ported though, but they do have a 4" inlet.

[turbo535]

So i guess its a to4s then
the exhaust is a non wastegated 3" v band outlet (yes small turbine housing)
I am running a 50mm wastegate

Anyway since you know it all guys know what turbo it is what do you think??
thanks

[GodFather]

to me sounds like the gt35r...especially if it says on the exhaust housing .82a/r and it has a to4s ( 4" inlet, 2.5" oulet ) compressor....

Max 650whp I say.

[techno550]

If you want to know exactly what turbo you have, take a bunch of pics and post them. Someone here will definately recognize it and/or figure it out. Pictures and measurements of the turbine and compressor with the housings off will help too.


oh yeah, :lol at wankelnut
