GT30R 16g hmm?

[chronicvex]

I bought a big 16g with a GT30R Compressor wheel. I was wondering how much I can get out of this turbo? I am using an evo 3 16g right now, is it a upgrade? Can someone tell me a estimate of how many lbs/min this should be pushing? How much PSI could I run on this with stock internals, ported evo 3 mani, 560 evo 8 injectors, and evo 8 fuel pump rewired? Right now I'm running 20 PSI with my evo 3.

Thanks for your input!

Depends if it's really a 30R compressor, as well as what turbine it has.

 

[chronicvex]

Ported 7cm turbine housing. I bought it from a repped member that builds turbos, so I'm assuming its true.

 

[bastarddsm]

that doesn't tell us much at all. GT30R describes the turbine size and that it was ball bearing...neither of which you have. You need to know what compressor it has, the 71mm or 76mm one.

Same deal with 16g, That just describes the compressor wheel. You need to tell us what turbine it has. You'll probably want a TD06 or 06H for the 76mm wheel.

That's the housing, not the wheel.

Post photos of the turbo so we can see what you're talking about.

Sorry about that..

That looks like a T04B S-trim compressor, not a 30R.

Pull the cover and measure the exducer of the wheel. If it's not 71mm or 76mm, it's not a 30R wheel.


It has an unclipped TD05H turbine, so even if it had a 3076R compressor it would be limited to around 45 lb/min in a 7cm housing. This is all information that should have been explained by the person who built the turbo. What kind of turbo shop can't give you factual airflow information on what they're building? ( PTE)

Having previously owned a 30R, I would say that isn't a 30R turbine or compressor wheel.

 

[warp9]

30r has a 6 blade comp wheel. What you have is maybe something similar to the hta68 wheel in size? So that would be 45-47 lb/min

I'm still saying T04B S-Trim. Here are two examples:

....and if that's the case:

The very tip/top diameter of the inducer: 1.9 inches/48.45 mm
The bottom diameter of the inducer (where top of the smaller inducer blades start): 1.99 inches/50.66 mm
Exducer diameter (or diameter of the entire wheel itself): 2.75 inches/69.92 mm
Exducer height at edge of wheel: .235 inches/5.99 mm
Wheel height: ~1.021 inches/25.95 mm

To4B S trim wheel has the same dimensions. I have no idea how many fins it had. It was less efficient than the EVO3 16G at any boost level.

Older 30R's (prior to the ported compressor cover) had 7-blade compressors (FP3055 era).

They're also much larger than a T04B S-Trim.

Its 71mm

Good to know..Thx

 

[chronicvex]

Any input on it being 71mm?

 

[omega260]

I'm a newbie, but isn't that wheel going to be bottlenecked by both the compressor housing and hot side?

I'd still like to know the inducer spec- even the T04B S-trim has a 70mm exducer which is really, really close to the 3071R. The inducer spec will tell the tale- if it's 48.3mm, it's a S-trim; if it's 53mm, it's a 3071R.

Keep in mind it's a 7-blade wheel, so you can't measure straight across....you'll have to go from the centerline of the turbine shaft to one of the inducer tips, then multiply that number by two.

Give yourself a little credit- you're absolutely right.

More so the turbine housing and wheel spec than the compressor housing, but total airflow production will surely be limited. The map shows the 3071R wheel (if that's truly what this turbo has) to be slightly more potent than a 20G at around 47lb/min...but that's also assuming it's being turned by a 30R turbine which is known to handle 65lb/min itself. Instead, this is mated to an unclipped TD05H turbine- so I'd speculate it's total airflow production to be in the 43-44 lb/min range, putting it on the same level as a 20G.

Some 68HTA users have reported logging nearly 47 lb/min; then again, the 68HTA is a billet wheel with a much smaller hub and more total blade surface than even the larger 3071R compressor.

 

[chronicvex]

Its 53mm

Thank you for input! Safe to run 20 psi on stock internals?

Wasn't aware of that

Well heres some serious newbie theorycrafting, but what if you could use the td06 20g compressor housing with the same hotside? It would have the spoolup simlilar to a 16g, but flow more then a td05 20g right? Idk haha.

On a sidenote has anybody used the 10.5 hotside on dsms? I know the evo 9 turbo has that, but they dont fit on dsms.
