Good stuff Colin... looking forward to your results as well. I'm def open to swapping out someone els's kit. But at the same time... I think we would have to do a few different dyno sessions. One with OEM UIM and OEM Throttle body etc but still keeping the long runner. Then one with the same set-up and a shorty turbo mani etc. Then one with a shorty with the custom UIM/tB set up....and on ya know? That would be a royal pain... but if someone helped me with it.. i'd be down for sure.
If you are serious man, maybe we can coordinate this winter when my car is off the road. I need an excuse to go out to Cali. Just give me a place to sleep
We could split the cost of the dyno, I would be EXTREMELY interested in the differences. Since we are both running a simmilar turbo all of the custom components should swap over. We could run your turbo vs mine (p-trim) on each manifold, The connections and DP flanges are the same so I do not think It would be too hard.
Let me know if you are interested. We could do both runs the same day and the only variable would be the manifold. Especially if you are able to squeeze a 4" DP in with your setup.

I think I would only need to bring the:
1. Manifold
2. wastegates with dump tubes
3. Turbo, With drain tube.
4. Down pipe
I think that is it. the only "problem" would be mating the compressor outlet to the intercooler due to the different turbo placment, but I am sure we can figure that out
.
What is nice is the turbos are similar except I have a P-trim so when swapping turbos on each manifold we would be able to see the difference the higher flowing turbine makes.
I would like to keep as many items form your setup the same as possible so we are only testing one variable.
For connections, if you do not make hardlines then I think the oil feed and water lines will work however I can bring fittings and hose just in case.
What is good is we both have dual pre turbo EGT's as well so we would be able to compare those numbers as well.

The outcome I foresee is more power than your typical GT35R because you have the X compressor and also a less thermally efficient exhaust manifold that should flow well.
I think it will turn out similar to if you had just used a 1.0 or 1.15 T04Z but with a lot of extra engine bay heat.

We already know the Gtx series is more efficient than the older gt series.... That's why John and I bought it. the turbos are secondary to the exhaust Manifolds. The long runner won't be much less thermally efficient and long runners have benefits over shorties and vice verse.

Your exhaust manifold is new and innovative but your wastegate placement isn't optimal , I see terrible boost spike problems in your future.........still good luck with it!

You are very welcome even encouraged to 'prove us all wrong' by providing the test data. Then the decision about the boost rpm and throttle response being better can be made by a panel of your peers

I remember reading somewhere that good wastegate placement dictates that the gate be placed as close as possible to the high pressure area just before entry into the turbo and that it is very difficult to ask a gas molecule moving at 350 MPH through a pipe to suddenly change direction , this is why "good "placement means making the opening somewhere in the path of the flow to divert the gas to the wastegate opening .Page 2 of this link , http://www.turbosmartusa.com/wp-cont...owergate60.pdf , to TURBOSMARTS POWERGATE 60 manual may help to validate what I am saying , hope this helps.
