twin charging - wastegate, bov, routing

FTR I would never do this from scratch but since I had all the parts I thought let’s send it! Since you can’t really make the exhaust feed a small turbo, then a large one and hope to fit those in a sled this is the next best thing. I also like having a fixed 10-11 psi always on, then adjusting the turbo with the ECU for gas, air temp, etc. also no way to have a single turbo make 29 “good” psi and not have some lag. I’m excited to get it out in the white and see if I can dial it in. The turbo is a large gt30-gt35 spec. I’m also going to spin it around 12,500-13k rpm. I really need about a week on a dyno to just carefully up things and see where it stops making power. At some point it will fizzle out and thats we’re I’ll leave it.

Getting there!

As a follow up and still looking for critique, I plumbed the IC to the boost control solenoid on the Tial Wastegate. I am using a Motec 4 port control so I have a top and bottom port on the Tial being used. My thought was that I wanted it to see compound boost only and not vacuum. The WG will remain shut until it gets to 23 psi roughly. So going down the trail I am expecting that it will be seeing boost and keeping the gate closed, and the BOV will be seeing vacuum and blowing all the boost off. I was thinking the boost would help the reduce the mechanical load of the SC and improve mpg. Everything else is behind the TB this includes the Exhaust Valve, FPR, Boost/vac gauge, MAP sensor, and BOV.

First ride this weekend on the lake just doing testing, datalogging, tuning, and repeating until hopefully I get it all to play nice to each other.
