mac71 Posted May 23, 2006 Share Posted May 23, 2006 I've searched on the boards but cannot find the answers I'm looking for. Does anybody now proper specs for the RB26 and leak down figures. What % is safe and what is not? Thanks, Adam Link to comment https://www.sau.com.au/forums/topic/119200-leak-down-test-specs/ Share on other sites More sharing options...
nfi Posted May 23, 2006 Share Posted May 23, 2006 I don't know specifically for RB26 but the general consensus is that brand new performance engines have less than 5% leakdown. Up to 20% though is "acceptable". I personally would be concerned though if it was over 10%. Hope that helps.

mac71 Posted May 23, 2006 Author Share Posted May 23, 2006 thanks, that does help. Still would like some input on the RB26 motor though.... Anyone ever done one before? what were your findings?
