Wierd application, hypothetical question.

[justin ivan]

Pat ,
You raise an intersting point about a waste gate controller. Now did you 
mean an electronic version (Ala Apex i AVCR) or a regular mechanical waste 
gate actuator? Either would work well.
I agree with you notion of this being necessary at all, if it was deemed so 
I think that a mechanical format would be the best.
On a side note, not knowing too much about diesels, how about a propane 
injection instead of the turbo. I am not sure how well they work on a N/A 
deisel but I know that on a turo diesel they make phenomenal gains in hp and 
esp torque.
Justin
