Slant 6 Turbo 68Dart Project

what do you have the wastegate hooked up to? with the mechanical advance slots closed to around .301 you can run 10* initial. the .301 will give you 8* mechanical advance. the vacuum advance will be over 18* and drop pretty much as soon as the boost comes on. if you are running 0-1* the 10 initial should help quite a bit with drive ability and spool. sounds like you need more accelerator pump action going on. check the clearance between the arm and the linkage. should be next to no space in there. it should start to piss as soon as you move the throttle. may need to look into a different cam. they are color coded. if you look it up you should be able to find what you need.

Wastegate is hooked directly to the snail shell reference outlet after a bleed control, which is all the way closed I'm assuming. It's screwed down all the way, rather than longer.

There also appears to be a leak somewhere below the wastegate in my piping or something because the exhaust wrap is charring only in that one spot. I can just kind of tell the wastegate itself is probably done. It was free, no big loss. New one was only $40 and adapts to the housing itself, and should allow at least 5psi I'm sure. Maybe 8 with the air bleed adjusted.

I'm glad the car can have some initial advance. It definitly needs it. The way I read everything it always sounds like people are running from 0* adv/ret. 10 sounds like it will work just fine.

And the vacuum plate will pull back all the way during boost? Or does it take a few moments? If it's instant, then no reason not to use it for fuel mileage and driveability sake.
