Kurt, in a previous post I had purchased Ferrari 458 and Ferrari California headlights to see if I could make them fit -- nope. I've tried a bunch of OEM lights and nothing seems to fit. My conclusion is to 3D print a smaller custom bucket, cover it with carbon fiber, trim the stock polycarbonate lens on all sides and add a dual beam projector and a switchback DRL. Since the lens is stock, I don't need to change any of the curves on the body. Rather, just fill in the gap.I cannot see past those headlights!! Those are SHARP. I like A lot!!! Did I miss a previous post on that mod?
Neil, I'm sure that there are multiple commercially available solutions for jetting a 3/8" hole, but everything I found was pricey fill-out-a-form to get a quote type of deal. The largest Jet Holley makes is a #110 which has a 0.156" hole. The opening I'm looking to restrict has a 6x larger cross sectional area. In fact, the jets have a 1/4-32 thread which is smaller than the opening. The objective is to restrict the fastest jack(s) on the car to better match the slower jack(s), not slow the entire system down... I can do that by adjusting the pressure on the regulator.You could have saved yourself quite a bit of work by simply using Holley carburetor main jets as the restrictions. Bore a shallow hole in your fitting and push in whatever size hole you want. They are widely available and cheap.
Neil, even the 0.200" jet is 72% smaller, so I would need to put 4 in parallel to have no restriction. I could get that down to three if the jets were left out all together for the fastest jack, but adding one jet to tune the next slowest would be a 22% increase so I'm really stuck with 4. Rather than drilling and taping a single hole I would need to drill and tap a hole for the adapter and drill and tap 4 holes for the jets. I would the need to repeat that two more times, so that's a total of 12 additional tapped and drilled holes.Holley alcohol jets are made in sizes up to 0.200" in diameter; By using multiple jets in parallel, one can "tune" the flow rate over a very large range.
