Hey X47 users I'm looking to compile some data from you on what your turbo is doing in terms of spool and psi levels. Note this only applies to the basic X47 (not + or ++ or R or whatever they are called), so that I can compare apples to apples. My reason for wanting this data is that I spent $200 on a ported manifold from SourSkittle and installed it along with my turbo recently. My tuner told me that my logs look about the same as every other X47 he's tuned which are a bunch. So I believe the $200 was spent in vain as I was led to believe (reading the SS ported manny thread) that it would make the turbo spool quicker. Of course that may be the case in whatever turbo SS tested it on, I don't think he ever tried it with the X47 though it would seem to apply across the board...in any case, benefit of the doubt there.
I did search the X47 thread but there isn't much real info as to what I'm looking for. Also I realize the X47 is old news but hey it's new to me so this is all very interesting.
So, on the X47 according to PumaSpeed the manufacturer...
X47 295-300 whp
The X47 as most USA customers are using isnt rated at over 300whp, we religiously see 295 whp.
Boost level are perfect at 1.75 (25.4psi) lowering to 1.65 or 1.7 bar at 295 whp
My tuner has my tune at this exact spot so I am happy about that. Holds a bit over 25psi for a good while then tapers to 24psi at redline. I'm assuming without e fuel or meth we are at the same place.
So my question for you X47 owners is, can you post when your turbo hits these benchmarks? (you'll have to round up or down)
1 - what rpms you hit 10psi
2 - what rpms you hit 20psi
3 - what rpms you hit 25psi
4 - what rpms you taper to 24psi (to redline)
5 - what fuel you are on to accomplish this
If I have quicker spool than others, the ported manifold was worth it. If not, I wasted my money, maybe, unless there are other benefits I'm not aware of....
***********************************
OK me first, from a recent datalog:
1 - 2800rpms at 10.44psi
2 - 3100rpms at 19.98psi
3 - 3400rpms at 25psi
4 - 5900rpms at 24 psi, steady to redline which is 6500
5 - 93 octane pump gas

Thanks in advance!
