Wastegate signal - anyone tried moving it?
Got the idea from the SRT4 guys, with the SRT it's common practice to move the vacuum tube from the compressor itself to just after the intercooler, so that the turbo will make up for any pressure loss across the core. Any Miata people tried this?

Just so I'm clear, I'm talking about the signal to the wastegate actuator from the turbo. On my Greddy the signal tube is about 8" long and comes directly from a fitting on the turbo itself. The idea is to get the signal further downstream to trick the turbo into spooling faster and producing a little more boost.

Yeah, I know what you mean. I guess it might help it spool a little faster since it'll start bleeding the boost off a little later. Never thought of it like that. But it still will only make as much boost as you set it for any loss through the IC is already made up for since you are setting the boost level post IC anyway.

it would be almost like a "crack pressure" adjustment on an electronic boost controller...
It delays the wastegate's acquisition of the boost signal..... based on distance rather than duty cycle..... and lets the turbo spool a bit more before the wastegate opens up to regulate the boost.....
