Waldi Posted March 7, 2019 Report Share Posted March 7, 2019 Make sure the LRHs ( low resistance holes) are equally spaced, of the same diameter and smooth contoured radiussed to have an even flow distribution. YTFE (you true flow expert) Quote Link to post Share on other sites
Steves_TR6 Posted March 7, 2019 Report Share Posted March 7, 2019 Are these ‘special low compression’ valves that allow fitting of a supercharger to an otherwise too high compression engine Andrew? if so i’m in! steve Quote Link to post Share on other sites
Hamish Posted March 7, 2019 Report Share Posted March 7, 2019 TR6 ? i hope you have only done the inlets as that is where the free flow is needed. Nice engineering tho Quote Link to post Share on other sites

Nigel Triumph Posted March 9, 2019 Report Share Posted March 9, 2019 It's so obvious that I can't see why this hasn't been done before. Conventional valves only allow gas flow for the roughly 270 degrees of crank rotation that they are open. These new valves will flow significant volumes of gas for the entire 720 degrees of the four stroke cycle. That's got to be better! In fact, since they don't need to be open to flow, the camshaft, push rods and rockers can be binned, giving a further weight saving. Nigel Quote Link to post Share on other sites

Nigel Triumph Posted March 9, 2019 Report Share Posted March 9, 2019 Guilty as charged... Too much time, too much imagination and too little knowledge! Nigel Quote Link to post Share on other sites
