How long is the WRC restrictor 2in wide? How long are the intercooler pipes 2in wide? Losses are real.
Don't get me wrong, I'm certain that 2 inch pipes could get to 400 horsepower, it just might take a lot more effort and therefore heat from the turbo to get there. If I was limited by some sort of rules for a particular racing series that would be one thing but for an open modification track build I would not consider it. |

Thats a really neat way of doing the wiring.

Temp IC setup,
https://cimg8.ibsrv.net/gimg/www.mia...e40a35da2.jpegReady to boost When I started testing the new engine I had stock fuel pump and aeromotive fpr, when I turned the key on (no crank) the fuel pressure would go up to 60psi~ and stay there... After a day or two when I did that again I noticed the pressure would go to 60psi and then to 0. I replaced the pump with a dw200 and the pressure acts the same, when the engine starts the fuel pressure is good and now tuned to 32psi~ idle and 43psi~ when on the throttle. I have hard time cold starting and warm start is not perfect too, could be the 0 pressure before crank is to blame ? or just tune it ? Is there any one way valve the failed ? Thanks Elior |
Normal behavior afaik for the pressure. There is no check valve to prevent the pressure from going down after prime.

Turbo is dead :\ there was a little metal flack in the restrictor... could be the oil supply was interrupted...
https://cimg3.ibsrv.net/gimg/www.mia...e24095c1b.jpeg https://cimg4.ibsrv.net/gimg/www.mia...1260973f7.jpeg Turbo will some times spin normally and then stop and have a difficult point (all by hand) Ordered a different one, maybe I'll get CHRA for this one. Was there any way to avoid that damage ? I run fine before boost, now it sound like a police siren when running. The first oil filter came out ok, with very little metal dots if any. Elior |
So you smoked the bearings in the turbo. I went back to see what turbo you had, and all I found was 5 pages of people telling you to not use that location for an oil feed, or risk the turbo AND head. Hope the head did ok.
live and learn I guess. Was looking forward to a dyno day. |

You think it's the oil feed source location that caused the failure ?
|
5 pages of people telling you it would fail. It failed. What do you think?

I've seen the size of the oil orifice in the top of the block at the head gasket where it feeds oil to the Head. It is already quite small. Taking a lot of that oil away from the cams and valves might be a bit of an issue. And if you have a journal bearing turbo that might limit your oil a little as well.

We've done over 100 easily.
We have had a bunch apart years after doing them and the cam journals and all wear surfaces look normal. It's a super clean way to do it and seems to work fine... But that's just like... my opinion, man. Dann

Thanks for the input Dan, I think I'll keep me sexy oil line :)

I think the oil source was not filtered, the new built engine and head must gave some debris and probably that caused the partial blockage that killed the turbo. The classic oil source is better in a sense that it is after the filter, that is the only pro as far as I know for now. 800$ turbo dead. Next please :) allready ordered |
Well, and as you were told for 5 pages, it has better flow. That's also a pro.
|
As far as I tested the flow is now issue. |
Well there we have it. its not a problem. Put the new turbo in and leave all the other stuff just like you had it. Do it for science.
Backing out now, I dont want this retardation to spread to my brain. |
Works fine. My turbo is trashed because of it, but it works fine.
Oh ok. |
you guys still haven't figured out that he's special?
The feed line is not his only problem. in fact, it's probably the least of his problems. |
