A stack of parts showed up this week. I picked up a set of 3" exhaust tail pipes. I want to run the exhaust all the way out to the rear. I'm not sure yet if I want to neck down to 3.5" on the down pipe then 3" just before the rear axle or go down the 3" at the bottom of the 4" down pipe and out the back. Folks say at my power goals I'm likely fine at 3" after the down pipe, but I'm weary.



I mocked up on the left side, but I will be using the right side as I have all the fuel system running out the left, plus the turbo is on the right.


I got a custom harmonic balancer put together. An engineer I know did the fabrication of an outer ring and a bolt on weight for his car to match the OE 4bbl balancer that is near impossible to find (can't even find a picture of one on Google!). But he never got it put on a center hub. I had Dampener Dudes in northern California put it together for me. I need to find the allen bolts and bolt it into place. I may have issue now with my crank trigger wheel. I need to check the diameter and may have to do something different. Worse case I used my 1bbl balancer for the duration of Drag Week. Dampener Dudes did a fantastic job. Lined up the timing marks perfectly.



I also got an LED display to put in the hood tach housing. I tested the LED display in my Skylark. It was reading about 4x more rpm than it was running, so I think I need to make a reference/pullup circuit for it to make it read right. I'm slightly concerned it may refresh too slowly to be of any real use, but I'll reserve judgment until I get the reference circuit complete. It was only $10, so not big loss if it doesn't work perfectly. I'm thinking of wiring it into a 3-position toggle switch and be able to switch it to display MPH as well. I'm also going to put some indicator lights in the housing, like a shift light, check engine, etc.


I also got in a 250amp fuse and case I need to wire in at the back of the car, as well as larger ground cable, so I need to re-run the ground cable. The engine bay looks so empty without the turbo!
