Twin Turbo Datsun 510 - powered by 300ZX. Drive by video - sound level comparisons

Image
Both passes are 3rd gear @ 25mph Here's startup and drive bys (both directions) in quiet mode. At about 3 houses away you don't hear the exhaust anymore  Drive by in loud mode - you can hear the exhaust at least 2x as many houses away, but the sound has a good quality to it, in my opinion. Here's a drive by where I give it some throttle while in loud mode. Since this is in a neighborhood I don't give it the full boot, but you get the idea. This is jyst for a cover photo for this page

LED headlights? Check  Daytime running lights? Check! Sequential turn signal ** update 7/10/2025 ** after running this delay for a few days I decided it wasn't as convenient as I thought as there's no way to immediately turn them off/on again as you would to let other drivers know their own headlights are off. -- Original post --- Headlight delay testing. DRL's come on automatically when the key is in ACC mode, headlights require the key in ACC mode plus the OEM switch. Power to the lights pass through an adjustable delay relay which I set to 20 seconds. Turn the key off, and the headlights turn off in 20 seconds.
