Thanks guys. I built most of the recirc side of the kit, and it is a PITA to do. Merging two pipes (one from each gate) then going in to the down pipe is very time consuming.

If this setup goes into production (depending on demand) recirc wastegates may not be an option at all.

You will have to explain your theory.

I was thinking that since exhaust from one wg will hit the exhaust from the other wg and than go into the exhaust it might create some back pressure causing a boost spike,
Just a thought

Improper plumbing before the wastegate is the only thing that could possibly cause boost creep. There is no chance this could cause any issues, and it is at about 45* as is. Picture is a bit deceiving as well.

That piping is well over the size needed to flow the extra exhaust. Waste gate gases won't be near full exhaust since most of it is going through the turbo. It's just left over exhaust gas therefore doesn't require all that much for pipe diameter to accommodate this.

screw recirc. I'll take 2 open dumps. Get this finished so i can have it on my car next month

Jeff, this kit has a name attached to it already, sorry.

You can have the next one I build (can make it open dump).

Keen to see how you route the cooler piping.

This is looking viable for RHD so far. Very keen to play guinea pig once I have finished assembling parts for my build...

I thought the twin scroll design was more of splitting up the exhaust pulses rather than the banks. Like on a honda to do a twin scroll you would have to merge cyl 1&4, 2&3...something like that. I might have my idea wrong for a v6 config.

VQ firing order: 1,2,3,4,5,6

Timing cover side.

......1
2
......3
4
......5
6

Firewall side.



By keeping the banks divided, you are indeed keeping the pulses seperated as well between each firing event.
