cold start video

[anyonebutme]

Just dropping this short video here, from a chatbox discussion. Basically just to show how quickly the engine builds oil pressure and fuel pressure on cold start. Has a very large oil cooler half the size of the stock radiator and denso pump hotwired, cranking right off a jumppack so it has low voltage and is cranking slow (equivalent of trying to start on a half dead motorcycle battery). Unheated garage, but starts just the same out in 30* after sitting for months because I just pulled it in a couple days ago. In this video car was sitting for 2 days. All oil lines -10, BTW. AEM FPR on robbeck adapter and stock FPR both react similar for me, this vid on stock FPR, which bleeds down in a day or so on my car, but has much more judder under boost so i try and avoid using it.

The two discussions revolved around does an AFPR that bleeds fuel pressure cause extended cranking and does a mongo oil cooler have any effect on dry start oil pressure when your filter has a drainback valve. Even though I think I answered both questions I figured I'd shoot a quick vid on way to work and throw it up, in case someone else was having thoughts about it. Since it's on jumppack, ECU was reset everytime I turned it off. Usually starts even faster on the battery.

Low cranking voltage causing gauges to reset during start, but you can see oil pressure rising immediately.
