I think you should have welded the wastegate back into the exhaust pipe at the lower elbow where the pipe is larger and exhaust is already flowing in that direction. Where it is now makes it look like the waste gate will be causing the turbo gasses to hit a ( wall ) when the wastegate dumps the gasses straight into the pipe at a 90 degree angle. Also if you need clearance you could run the half size radiator. Other than that in for results good luck nice build.

I agree there could have been a more optimal way to recirculate the wastegate. I wanted to run the wastegate into the 3" pipe, but the work vs. reward didn't seem worth the time. It doesn't enter at a 90deg, but more like 45deg although it is hard to tell from the pics. It's hard to know what the actual effects will be so it is really a guessing game without the ability to try multiple setups or model.

 

I basically agree with this statement. I myself would have liked to have seen a more reduced included angle of merger between the WG dump tube and the turbine discharge pipe. The exit flow of the dump at the merge intersect point appears to be almost perpendicular to the axial flow path through the turbine disharge pipe. 45* just seems too abrupt. A little less than 30* included angle, maybe about 27* seems less disruptive to me.

Don't get me wrong. I admire the excellent craftsmanship and overall innovative design of your setup. The angle of merge was one of my two reservations with the overall design though. If you ask me I'll tell you my second reservation.

Of course, I am really being picky. You are doing an almost perfect job. It is something that I would duplicate or purchase if I only could. Congrats on a most beautiful and unique, turbo kit.

 

UPDATE:

Not too much to update as the manifold, turbine housing, and wastegate dump were sent to have custom heat shields made. During this time I have got a few things done such as port the downpipe, have my new IC pipe beaded for the couplers and made some heat shields for the AC stuff.

 

UPDATE:

I got some pics of the mockups for the new heat shields. This was to agree upon the approach before fabrication. I should have final pics of the inconel shields by Friday.

 

UPDATE:

Heat shields are finished.

 

Wow, that's different.

 

thats crazy looking, how much does something like that help with temps?

I don't have quantitative measurements, but have used these on several projects in the past. It is about the best stuff I have found to eliminate radiant heat generated by the large surface area of the turbine housing and exhaust manifold. It is good, but not cheap.

Even though I have the shields the turbine housing was ceramic coated and I will also coat the exhaust manifold, wastegate dump, and downpipe. This is DIY stuff so I will post pics.

 

If you could let us know where to get that stuff, that would be great. I'm interested.

 

UPDATE:

I completed the DIY coating on the downpipe today and it went well. My intent with the coating is more cosmetic as opposed to relying on the coating to eliminate radiant heat. With that said, the manufacturer claims that it indeed helps. I purchased the following paint:

I like this paint because you can post cure for 1hr @ 750F or you can install on the car and allow the exhaust heat to cure the paint. I first had to sandblast the pipes and then wipe them down with acetone. This was all that was required to prep the pipes. I then purchased a detail sprayer from Harbor Freight for ~$12.99. This unit worked extremely well and was very easy to use even for a novice.

That is about all the detail that I have except for some pics. The paint dried within a few minutes, but won't fully cure until the car has been run. The pics are somewhat deceptive, but the paint looks good and is indeed satin black.

 

BTW, I will be coating the wastegate dump tube and manifold once they return from Advanced Thermal Products in CA. I also added some heat reflective barrier to the oil pan since I had extra.

 

UPDATE:
I got back the parts from ATP and bolted them onto the car to ensure fitment and clearance. Everything looks great so I am ready to start moving forward on the setup. I need to port the RevHard exhaust manifold and apply the high temp coating to it and the wastegate dump tube. Following these minor tasks I will start to assemble the setup to get it ready for action.

 

Looks great

where did you get your bellows from?

the heat shields turned out awesome.... great templates btw....how much did the shields cost?

 

Aby I'm interested too
