Do you have any problems with oil drainage from the turbo to the pan? Not at all, and I am using the front drain also. I believe I use -10AN on that one.
Did you get that exhaust flange from Racing Beat? Yes
Did you use 304 or 321 for that runner? 321 SS from Burns stainless. everything is 321 up to the 4". The 4" exhaust is 409 and it starts at about the rear of the transmission.
Are you running water/coolant to those wastegates? Not at this time. This is one of my next season projects because I have over heated the rear diaphragm twice at a race limiting my boost to 15psi which = slow. Also I might have to relocate the WG since it is close to the DP.
I can't believe you were able to route the WG dump back into the exhaust too, that's awesome. It was not easy, also in SSM we cannot run open WG's. All exhaust must exit rearward of the rear axles.
What brand IC core is that? Did you do the same size piping on both ends of the IC? the IC is a cheap ebay core, I was experimenting and did not want to spend big bucks on a IC if it did not work. Also it is 2.5" in and out. I think I have pretty good response if not too much sometimes. Bell IC cores would be my first choice too.
Have you ever used a different IC and different exhaust manifold with that turbo? If so, is there a noticeable difference in response between this setup and that one? I have not had anything different, I plan to change something this year if I have time. I went from a stock set up to this so with that it was a BIG difference.

Ok, I thought I might have seen evidence of that, but I thought maybe those things were just holding the screen on the back.
So glad to hear you don't have any issues with oil drainage. I'm kinda worried about the waste gate being heat soaked though, but I guess water cooling will help that. Have you thought about where you're going to get the water from and route it back to? Where are you thinking of relocating it to? Have you thought about making a heat shield for that WG?
Is there any concern welding the 321 to the 304? Mainly about cracking where the 321 meets the 304 flange? About the 4" though, is it not started at the back of the turbo? Or are you saying you started using 409 at the rear of the tranny and prior to that it's 321? That must have been pricy for all that 321 lol. So THAT'S why you plumbed them back into the exhaust. I wonder if there is some kind of quick disconnect for that piping to make it easier to connect.
Yeah I can understand using a cheap core for an experiment. Do you notice any drawbacks to that ebay core? I guess it's working for you if you're racing with it lol. I'm still wary of what size core to get, I'd rather experiment with a cheap core too but if it works I don't want to build another one with a name brand core. Although maybe it would still be worth it to try.
So as far as response, what would you say about how much difference there is between this and stock twins?
That fuel setup is crazy haha. I'd love to do something like that, I'm just not sure what all to do.
Thanks for the help!
