Looking very nice Carlos. I will have a third turbo to send out to you later this week. I need to pull it apart and take some measurements before it gets sent.

 

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.

 

They allow movement better than a straight coupler.

 

Yes, but will it change the flow characteristics of my charge piping?

I am guessing yes.

 

I'm guessing it wont.

 

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'

 

I say do both and see which of us is right

 

Sounds like a great plan, I will post logs.

 

If you're going to ultimately just post VD plots there's enough other variables in play that you'll waste your money IMO. I agree with @aidandj.

 

I am ultimately going to use the same real dyno I used before and run the same tune except for EBC. I want as few variables as possible.

 

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.

 

yeah, the way it comes on is super lazy. other one moar bettar

 

Yep I expected spool on it to be a bit slower. The compressor side is HUGE.

 

it looks similar to my 3076 from years ago. in which case 300-400hp should be not too unrealistic at full tilt

the compressor on that thing was nuts

 

I have a third turbo for Carlos to try out. I need to take it apart to measure the compressor blades to see specs for sure. Scott thinks it should be the same size as a TD04.

 

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.

 

I highly doubt it.
Unless it's kinked to like half it's ID

 

It is.
Ok maybe only 1/3.

 

Spool still shouldn't be affected that much. Maybe top end flow.
