thought I'd share an update on this project,
While technically you don't need a bypass valve at low boost levels but I wanted one in the system. Fitting one into the system has been a challenge for me. I've tried several locations and different valves and nothing really came together in the way I wanted. I took a little break and came back at it and came to the realization that the easiest and cleanest way was to include an intercooler in the system. This gave me the opportunity to easily cut into the transition pipe from the discharge pipe to the inlet of the intercooler.
The not so good news is that this will add design time and delivery time to the project and additional cost to the system and what was intended as an option is now going to be a standard.
The good news is that this will eliminate some fabrication work and the need for the intake extension pipe from the build midigating some of the cost of the intercooler and the end result will be a complete system.
So right now my focus is mainly on the intercooler. The intercooler will be available for the TRD units and built using Bell Intercooler cores.
As for the bypass valve, I bought one of the typical valves used on the TRD charger and other units for design and evaluation and found it to be leaky when closed and found a lot of complaints with smoothness of operation causing driveability problems on line.
At this point I'm going with a Tial QRJ 38mm valve. It fits my application and is supposed to have a tight seal and smooth operation.
I've been asked about a time line and the short answer is I don't have one. It's a very slow world out their right now.
