LIMITS of a 40mm Tial wastegate?
U can see it comes off the collector on the right side

Re: LIMITS of a 40mm Tial wastegate?
I'm kinda blind I can see where it looks like it goes into or possibly slightly behind cyl #2 runner.
IMO, the manifold looks like a decent design, but the wg looks like an after thought, from the pics I can see, it almost looks like the exhaust flow has to reverse to exit to the wg, as well it looks to only draw from cyl #2, that might just be the pic, but at most it is drawing from cyl #1 & cyl #2. This with angle of the wg tube with respect to the flow of the manifold, does not lend its self to an efficient extraction of excess energy.
With that being said, no one will be able to say for certain on your setup, if that wg will be enough or not enough, there are just too many variables. So run it, if it creeps, go bigger, if not run it. :1

Some of you ------s are really ------- blind. SRSLY homos look, here is another angle so you can see that it's coming from the collector and at a down graded angle so no ------- backwash like Simplexes momma does when I force a load down her throat and it backflows out her nostrels and eye ducts.
And a better clearer picture so you see the WG and the outlet port heading to the ground.

MUCH better pics.
Shouldn't be any worse then a typical ramhorn, not that they are great. The wg tube is better, then the other pics had led on. I think you will be on the edge of the capabilities at low boost, like around 7psi, but shouldn't creep much if you have the boost above that.

Yeah the hondata EBC/mac valve "whatever you go by" has a base dudty cycle set for 11psi and goes up to 19psi per respective gear. But I'm going to disconnect the boost by gear and just go by one set psi dutycycle and add more fuel because I know this turbo is going to lean out my mix being that it flow 30% more cfm from what I've researched. DMC1 holla at this cracker, may need your help for a bit of street tuning in mid spring.
