Pics of dp installed?
I'm using aem series 2.
Yes, to install the 3.5" downpipe the a/c compressor had to be removed. The 3.5" downpipe has a very big smooth bend. The 3"downpipe had a very abrupt sharp bend to clear the a/c compressor. The 3.5" downpipe reduces down to 3" before it connects to the exhaust, I just wanted the bend to be in 3.5".

Comparing a turbo at 51lbs to a turbo at 41lbs isn't exactly fair... but I understand the point of the comparison.

The 7163 should be compared to a HTA3076r or GTX3076r for overall power potential on .82 AR. Spool on a dyno is almost identical to these two garrett options, but transient is much better due to a turbine that isn't a turd and undersized. Not a knock on FP, as their compressors work well.
I really would love to see a hypothetical 68lb/min 59mm 7670 revamped with mixed flow and put into a vband in/out b1 frame. I am aware of the reasons it can't right now(mainly housing meat and turbine length), but the IWG 7163 packages really nicely in very tight places, like behind the motor on a Audi TTRS. It would be nice to have an upgrade path above the 7163

you guys need someone to tune that TT-RS engine for you?

Like I said, my car spools much faster on the street. The dynojet just doesn't put enough load on the engine. I was looking at some datalogs the other day and iirc my car makes 30 psi at 4500 rpm. My friend has a 2.0L evo with a 6262 on it and my car is more responsive than his.

Dragracer, what turbine housing are you using on the 7175?

Actually those runs are a single scroll 6466 maxxed out and cant make more power or boost and then the faster spooling 7175 making more power at obviously more boost.
That wasnt a 9180 comparison in the slightest. There will be no datalogs from either car supplied. Both were SLR2.2 Evo 8s and not a LR2.4 like Martin's car (8374 elsewhere in the thread). His is supposed to be getting a 1.45 9180 so we'll have some data but still nothing I feel I can compare that will be apples to apples.

Here is some EFR8374 1.05 TS data on a 2.5L Audi 5 cylinder. Flow on head is roughly 280cfm/220ex. It has a SP QSV spool valve installed. It is spooling pretty quickly on our Land and Sea AWD dyno, and using ~6300cc/min worth of fuel at .81 lambda Air/Fuel on e85. We will be turning it up to around 35psi in the coming days and we will spin to 8500. We are still breaking the motor in and sorting some issues.. Overall, pretty good results for only 25psi.
