Thanks! Unfortunately the compressor outlet is in a slightly different position and I cut my 90 coupler too short to reach. I have a hump coupler I could use to give me some wiggle room, but I don't like them which is why I didn't use it originally.
What do you guys think of hump couplers, do they eff up the flow? Especially for the purpose of this test, when I want to keep everything as consistent as possible.
I may have to order a new coupler on Monday.

I must admit, I am much more of an engineye or enginose than an enginear.
But we're both guessing and the whole point of this is to have as equal a comparison as possible. If I just get the coupler it will be the same, instead of introducing a new sudden increase then decrease in diameter shortly after the compressor housing.
Just sayin'

Had to cut my porting short this weekend due to local noise ordinance, but I finished this morning before work. I can't remember how I cleaned the thing last time. Hopefully I can get it back together and in tonight. I need to work on my taxes this week though.

New log, still need to play with it a bit but my initial impression is that is spools much slower. That being said it still feels pretty nice. I am not happy with my charge pipe configuration but I have a new coupler on the way.

So that was an initial test drive and my wife was bugging me to go to the store while I was putting it back together. I used the hump coupler but it makes more of a kink than a wiggle, I am really not happy with it. I am going to try to move some of the charge piping slightly before work to see if I can get rid of the kink. I honestly think spool will improve with the new coupler, arriving tomorrow, or if I can fix that kink.
One thing I will say is it is way harder to get the bottom left nut on the T3 flange around that huge compressor. I got it but the original turbo comes on and off ez pz by comparison.
