60-1 is what BRETTUS prefers. I think I'm running the equivalent of a billet 62 Trim.

You can get a T04e compressor housing with a 2.75" turbo inlet that will fit on the manifold. I have one and it fit on the manifold fine, the problem I had was fabricating a oil drain.

I went with a piece of 3/4 copper tubing 5/8 id. -10 fitting on the turbo and the oil pan drain.

So that is just a standard 3076 with a T04e compressor housing?

I ended up just putting the stock greddy turbo on because I ran out of time. I may try it again sometime next year.

In another thread I posted this link in Brettus 11 thread
FC3S Pro v2.0:&nbsp Turbo Tech - Compressor Maps

Looked a bit further:
Turbo Compressor Chart

But I'm struggling to understand it. I was wondering if the "Super V- trim" would be more laggy than the 57 trim? Compressor wheel has smaller diameter, as far as I can see, but same average(60-1 is larger, means more laggy I presume). At the turbine(hot) side, it say "see below", and I do not understand how to interpret it. Could someone assist/explain?

Something about the 57 trim that I found out after much searching of the interwebz .
The map that is commonly associated with it seems to actually be the wrong map . The 57 trim is actually very close to the 60 trim that they rave about in that article and in practice performs better than they suggest. I really doubt the 60 trim is capable of 400whp as they suggest though as you need around 60lbs/min for that.
The other problem with the boxes that they display in that article is that a 13b will flow a lot more air (at higher rpm and PR) than they show there . Past 7000 the Renesis will flow around 53lbs/min at a PR of 2.0 .

Where do you think the limit of the 60-1 wheel is?

Brettus

iTrader: (2)

It will do 60lbs/min at 2.2PR (18psi) which is right about where the Renesis would be cracking the 400whp. Which is why that wheel is such a good choice for anything in that 350-400 range .

golde4u

so where does that put the 57? and is it better than the 20g wheel?

Brettus

Here is what I believe to be the corrct map for the 57 trim



They are both 48lb/min wheels so prettty much the same

So if you were looking to hit that 310-320 WHP range would you recommend the To4e 57 or 60? I know I've read in other threads that it is pointless to run the 60-1 unless you plan to push high boost (15+ psi) and attempt over 350whp....

AAaF

Seems like you have stepped into a wormhole of questions here Brettus I really appreciate that you bother explaining, thanks.

In the map, you have marked points, and at 15PSI you have written 10PSI at UIM. I read this as you have a pressure drop of 15-10=5 PSI over IC? And this pressure drop makes the turbo perform better, and therefore barely are supporting our Aux ports. So if running 10-12PSI, then you should have second thoughts fitting "mother of all IC" in your setup.

So I'm wondering the same as RotaryMachine, would a 60trim be better maybe? Or would the drawbacks be bigger than the advantage for a 310-320WHP goal.

Another thing I notice, is that surge line at the 20G seems slightly more forgiving than 57trim, is that to any advantage for us? Making 20G might be the best option?

Brettus

The 60trim would be the slightly better bet if it's available. However both are marginal for anything over 300whp IMO.
The better bet just looking at the flow maps , would be the T04B H3.

Brettus

iTrader: (2)

The pressure drop I experienced was from trying to push a small turbo too far outside its efficiency curve and creating heat- nothing to do with the size of the IC.
What the map shows quite well is that the 20g,57 and even the 60 trim wheels are a little small to have the Aux ports left open. If you were to transpose the stock Greddy on there you would see that leaving the Aux ports open with that turbo is pure folly.
The power figures quoted on the map are a litttle inflated.I should redo it .

AAaF

Made a comparison for fun. Seems like you gain around 2.5lb/min.

Brettus

iTrader: (2)

Definately better but not as much as I thought . Looks good for that 300+ range though

AAaF

Well, 2.5 is almost a 5% increase. This means you can go from 315 to 330+whp, with the same margins. Or 400RPM extra at the same torque. Maybe what we will be looking for to keep rev range high and APV open?

RotaryMachineRx

That sounds like the preferable compressor trim to me then... assuming this is keeping the stock Greddy spec'd turbine as well as stock compressor and turbine housing?

Brettus

iTrader: (2)

Seems like it will work ok with the APV left open ... yes . If that is what you meant ?

RotaryMachineRx

iTrader: (1)

Same boat for me would like a compressor (sounds like to T04B-H3) that will feed enough to keep the APV open and break that 300WHP with a little room to spare

Brettus

iTrader: (2)

I've never heard of anyone fitting one to the Greddy but if the 60-1 fits I can't see why that one wouldn't.

RotaryMachineRx

iTrader: (1)

Oh, I thought you meant it was a wheel you could upgrade to with the Greddy the same as the 57 or 60 trim...... I've still got alot of homework to do and not enough time to do it at the moment haha

I just went back and checked my emails for the specs on mine when I had it rebuilt.

• Water & Oil Cooled CHRA
• BIG TD06H Turbine Shaft
• 54 Trim 44lb/min Billet aluminum compressor wheel from Comp Turbo
• New Bearings
• New Seals
• Machined Compressor Housing
• Machined Turbine Housing
• Balanced

She will be back in boost next weekend and at the tuner soon after so we shall see how it goes.

44 will be marginal for 300 ............ if that was your goal .
