71 Duster 360 turbo build
So I’m just about caught up at this point. The engine went back in with new pistons, and slightly thicker Felpro 1213s3 stainless core intake gaskets. However, I had made a discovery with my carb during my prior tuning which was that it could move a significant amount of fuel(650cfm strong signal). So I opted for e-85 over our(Arizona) awful 91. Except it turns out my local stations only mix e-50; even better since I get higher octane and slightly less flow required.
I pulled a LOT of plugs and tuned very slowly. only 10* of timing under boost. Fuel distribution was certainly an issue, and I now have the rear jets 12 sizes above square which I attribute mostly to the hat design.
Boost season is coming to an end as the Phoenix summer approaches, and we had one more track night with cool weather on 4/23. The car was sorted and I was excited to turn up the timing at the track. Took it for the famous “one more” tuning run on 4/21 aaaand it threw the fan belt. Spit up most the coolant, but started up and idled nicely once it cooled down. Unfortunately it seemed to want just a bit* too much coolant.
