anyone make any progress with these turbo's ?
i've got one coming and have been tossing around a few idea's .
add a 4 to 5 inch section between the turbo and exhaust manifold , off of the extension , add a "t" , in the "t" put a external waste gate ( something similar to what is on the mercedes diesel , or 944 porsche ) .
if i understand how the turbo works , it looks like there is a sliding ring that as it moves back and forth , it exposes the exhaust wheel to more or less of the exhaust gas.
i was going to use the same style vacume pot that is used on many other waste gates to mov the ring back and forth , But also install a adustable set screw to limit how far the ring slides over , hopefully reducing potential turbo over speeding .....
i was also thinking about also installing a solinoid that while non engergised would act as a stop preventing overspeeding of the turbo , but when energergised would allow the ring to move over farther causing faster spool up ( ie drag racing , pulling .... ect... )
