Team Escargot Posted November 12, 2009 Share Posted November 12, 2009 Leads on from other posts Do I need to (or is it wise to) retain my existing Apollo when I fit a CC DS? (r300 with hydraulic lifters) or is this just overkill? If retained, do I keep the oil temp sender in the Appolo? Nick Link to comment Share on other sites More sharing options...
Adrian Williams Posted November 12, 2009 Share Posted November 12, 2009 No, overkill. The R500 had an 'upgrade' which was a smaller than normal appollo to increase oil capacity if used in extremes. You don't need it, sell it to help fund the DS kit. See David Nelson's recent post on another thread, he explains what he did with the oil temp sender.

Johnty Lyons Posted November 12, 2009 Share Posted November 12, 2009 An Apollo is IMHO a poor mans Dry Sump Having an Apollo as well as a DS is senseless Just my humble 2ds worth jj MTM , N.I.

Peter Carmichael Posted November 13, 2009 Share Posted November 13, 2009 The problem the Apollo tank solves is fixed inherently by the dry sump system. If you run the dry sump with a sealed crank case (I have a well documented dislike of this practice), there is a marginal reduction in effectiveness of scavenging in the dry sump system which in extremis can lead to oil delivery problems. When I built my 250bhp K-series in 2000, I first ran it with DS and Apollo. This was when R500s were renowned for blowing up on track. My engine had alterations to the through bolts, resulting in reduced oil drainage and indeed I saw problems with scavenging leading to an empty dry sump tank and all the oil sitting uselessly in the engine. I was testing at Snetterton specifically to investigate this and I fitted the Apollo to minimise the harmful effects of an oil delivery failure. The problem came in at 7900rpm which was a problem with an engine that revved to over 9000. Just opening up a breather on the cylinder head made the problem go away and the only oil problems I have suffered since have been self inflicted.
