i would also love to see a dyno difference on the same car with the same mods of turbo upgrades like 50trim, dbb 50trim, 3076 and so on so forth. i kno it will take a lot of time but well worth it.

While I think this would be great info, I'm sure AGP has their proof to backup their claims for power on their turbos (unmodified of course).

Talked with Ben at AGP via email late last week about getting the components to me. The backorder on the garrett .63 turbine housings are no longer on backorder and can be sent for the testing.

let's get the party started then. I need to know how much more power you can get out of my standard AGP 50 trim.
Heh, patience young padewan....
It will still be at least two weeks until I get the manifolds and turbine housings ported (they aren't even here yet) but trust me when I say all results, good or bad, will be shared.

Bob just put me @ the top of the list for a Agp exhaust manifold ported by you.
I don't even need to see the test your work speaks for itself.
Ps. I not kidding put me on the List thank you
Sean
I received a nice package from AGP yesterday Three new AGP cast manifolds and three garrett 50-trim .63ar turbine housings.
I have taken some initial steps an measurements on them all for the start to the data compilation. I have made plates for the cc'ing of each part as well but have not gotten this far yet as my burette broke and I need to get a new one
I have/will update the first post with the checklist to completion for this project so everyone can stay updated. Expect at least another week and a half to two weeks from today before a dyno is in order.
What Turbine modifications do you plan on performing?
Cutting too close to the turbine wheel has shown be a lose/lose. It will reduce Mass Flow AND Efficiency.
Don't you think that inhibiting heat transfer via Ceramic Coating is completely counterproductive to the goals of porting a Turbine?
Do you think the coating thickness(.006-.012") will completly negate any metal that was removed?
Will you be willing to share the manufacturer and part # of the ceramic coating you'll be using?
We currently used a lot of Henkel and Dupont products
Will you be testing every combination of ported/non-ported/coated/non-coated ?
It would be most interesting to see the results of just a ported compressor housing over the baseline.

For your first Q please reread this entire thread. No, I will not be doing anything to ramps, or exducer bores in this testing.
If I were to use a thermal dispersant on the turbine housing it would pull heat out of the exhaust stream and make it loose velocity thus hurting spool and power.... it's a good thing that I am using ceramics that are thermally reflective/insulating. It has been tested before that coatings alone can add up to 2-6% more power in turbocharged applications. This is one thing that we are verifying in these tests as well.
Before you start with tolerances and GUESSING what my thicknesses of porting and/or coatings do you think that you should wait for the results? All measurements before and after will be disclosed. FWIW, porting can remove anywhere from a few thou to .100" depending on the application. The ceramics normally are applied from .0005"-.004" depending on which one I am using. So based on this, no I don't think the ceramics will negate any of my porting.
for your last question, again please reread the thread (look at the first post) and you will have your answer.

You state "Turbine housing" about 4 times but to the rest of society thats the whole deal. The losses I mentioned are more focused on the axial clearances from Inducer blade tip to the wall. As far as I can tell from your various pics, your porting doesn't give this area the consideration it should.

More heat isn't always best. When a gas becomes too hot and the velocity too great, the Mach number reaches 1.0 and the mass flow Chokes, as in STOPs increasing. Once the gas's Mach # = 1 it will not matter how high the pressure is before the Turbine of how low it is after it, the mass flow will NOT increase(without a shock wave that is). Obviously a stagnant mass flow will accellerate the turbine but it WILL put the kibosh on high RPM hp. If no more mass air can get OUT, it sure as hell can't get in.
Quick spools are great(stock turbo) except when they CHOKE too soon.
