Slant 6 Turbo 68Dart Project
Well figured that out. Wasn't fuel related at all - the blow off valve was leaking on the lower part of the gasket and it would slowly discharge when you let off the gas, then let it all out at once through the turbine hence the undulating noise. The blow off valve was not working, and essentially when it hit 5 you'd hear air escaping then the car slowed down. It will now hold 4 psi, and still opens at 5, but the car doesn't act like it hit a net anymore. I am curious if adding a BRPV to the setup will be a viable option to go for now.
I will also hook up the mbc and get that functioning once I figure out my kickdown. It was not operating properly and the car was really - really slow to start out, like it was starting in 3rd gear. I jerry-rigged a system to make it work ok momentarily, and it solved the problem, but now i need to build some permanent bracketry. I bought some more steel flat stock to make brackets, and will also use the stock to make some brackets to hold the boost hosing and wiring so it's not dangling in space. I may also choose another color for the engine bay. Not sure yet, but I'd like to clean this up and make it a little more cool. I am really a stickler for details like that, and right now, it's just not "pretty enough". ALso had someone look at it and they said "well it's rough, but if it works, it works" pah! jerk. It's not that bad. lol.
Here's how it sits now with some detailed close-ups.
I'm trying to find a rubber grommet for the valve cover i redid. The opening is not the same size as the chrome one so I have to find a different rubber part. I'll find one, get a new valve cover gasket, and then set that all up. Also thinking about painting the intake piping as the aluminum is just getting tarnished real fast. The piping on the uptake to the carb seems to be hitting a hood support as evidenced with scratches and some aluminum scuffed, so I'll have to cut that out of the hood brace section, but only a 3" wide piece or so. There's no making the piping any lower, as it already floats just slightly above the valve cover and alternator. Maybe the piping can be black? I don't know - trying to decide what would contrast well with a blue motor.
