Subject: Re: dry sumped C4 by MarkB on 2008/7/16 16:49:53 Hi guys, I didn't even realize this was posted over here. Thanks for the comments! For me, the dry sump wasn't required, but it's nice for piece-of-mind. I have to admit, the biggest thing was to see if I could do it. It was a fun, albeit expensive and sometimes stressful addition to the engine project  Bill, you can actually find the Hamburger's pans on e-bay. I got mine for $30. I welded in an additional scavenge fitting and pickup since the pan is only available with 2 from the factory. It's a very basic pan, no kickout. It does have a windage screen, though. I didn't put in a crank scraper. After talking with Roy Johnson (who built the pump) and my engine builder, they said it wasn't worth it at my power and RPM level. The next time I go to the dyno I want to see if it makes much of a difference without vacuum in the crankcase. Right now it pulls a little over 12"hg at WOT, about 7" at idle. The next project will be Gary's C4 coilover setup |
