First some background: Building up a PD100 (BRM) with a GTB2056VK and R783 nozzles. There are many other mods as well but not any that should influence the decision I need to make about the anti-shudder valve. The turbo is being mated to a short runner tubular manifold and will exhale through a 3" exhaust. For now I am using the OEM FMIC and most of the OEM pipe work. Thinking this should be OK with the sub 30 PSI tune planned. While the car is in the capable hands of David (TDIinTexas), I decided to go ahead with his dual plenum intake manifold more to improve distribution than for all out flow potential. My goals at this time are not outright peak performance per se, as the car is a daily driver and I am not yet beefing up the bottom end. However, it will be stout, I will be happy with 400 ft/lbs torque - give or take (for now).
Here's the issue: I would like to maintain the original ASV for safety reasons against runaway. David measured the ASV ID at 1.88". The intake OEM manifold inlet is 2.00" and my OEM intercooler pipework is around 2.25". The new dual plenum manifold inlet will be 2.50". The ASV might be a bit of a restriction now. It might become a bigger restriction if I go 2260, custom FMIC and bigger piping sometime down the road.
I am not looking to amaze with peak HP dyno figures with this build. I want a very strong car in the RPM range that I drive it 2000 (ish +) to 4500 RPM with a nice fat torque curve with a lot of area under the curve.
David is leaning toward ditching the ASV, I am leaning toward keeping it. Curious if anyone can make a compelling case for ASV or not to ASV for this build.
