Yes I got a mechanical pump with brass gears. Noisy but more reliable from what I've read. Now you got me reading about water meth injection ..damn
I'm also looking for the worlds smallest gauges for boost and air mixture. I have a 4# spring, a 6 # spring, and a 8# spring for the wastegate. I'll be starting with the 4#. I think it's easier to tune up.
I like to run a 3lb spring with an intelligent electronic boost controller. Much easier to control, and is great to be able to default to very low boost in bad weather or if a less experienced driver is behind the wheel. Only drawback is that a really good smart controller that can run closed loop feedback runs $500 up. My boost control in my 300C is part of the secondary computer controlling fuel and timing. I can program it to read actual manifold pressure so the algorithm will adjust the pulse width modulation to the solenoid to maintain the desired target boost. It can also be set up with an X Y axis table like a fuel map to vary the boost pressure based on the rpm.
I love my SRT6, but always prefer a solid turbo setup as I can control the boost and not be dependent simply on a pulley ratio.
