Whatever_Racecar Endurance 745T

this thing is cool. I'd love to see it racing against other cars too. I haven't seen many volvos online doing wheel to wheel racing

Grinding the wastegate housing is what I am referring to...

I am going to try the 316 stainless studs @culberro suggested, nordlocks, squished copper nuts, and resbond. I am also going to order some inconel studs from ebay and get a second manifold/hotside/wastegate set up. We will see which lasts longer.

Let me see if I can find the PN for the ones I used. They were unequal length on the threads and were perfect, I think the OAL was 55mm maybe? Alternatively, set screws make green studs.

I was just looking at the bay of them yesterday, but now I’m on a work trip for 4 days. I’ll see what I can dig up in my past emails.

And I’m thiiiiiiiiiiiiiiiis close to getting rid of the ultimate wastegate or doing something stupid. Heck, maybe I’ll MIG weld it on!

I couldn't find any info or even a for sale thread for the stainless studs I bought from John (The Aspirator) back around '09/'10. I used them with nordlock washers and I think (?) stainless nuts, and I didn't have any issues with the ATP housing getting loose. I have determined that the M10 studs that had been installed in the '90+ manifold I was using were probably not up to the heat. I did one track day with this setup and spent every off-track session tightening up the nuts holding the turbo to the manifold.

(that rubber water hose to the turbo eventually failed, lesson learned there, use metal pipe instead and get the flexible hose away from the high heat, like OEM)
 
Also, I never used a gasket between the turbine housing and ATP housing. I did use one between the turbo and manifold....I don't know if they contribute to the problem at all, but I don't think they are needed on a race car if the surfaces are flat.

I don't normally use gaskets, but I had one so I thought I would get it a try. It spat the wastegate gasket out and it came to rest on the v-band.
 
Is it a thread locker or sealant or both? Where ya puttin it? I'm good, nothing I own will be ready in 6 months
 
I repaired one of my turbine housings with the 50mm stainless studs and resbond last weekend. I have inconel studs also on the way for my second housing. I also modified another 90+ manifold for the T04E turbos I have. Plan is to have a manifold with turbine housing pre-assembled for a quick swap if necessary.
