Popular Post BOBWhite Posted October 15, 2023 Popular Post Share Posted October 15, 2023 This guy has been doing some great video's on Mack engines that I thought I'd share. A whole new generation now knows about about the tip turbine engines. 5 Quote Link to comment https://www.bigmacktrucks.com/topic/73425-mack%E2%80%99s-tip-turbine-was-ahead-of-its-time/ Share on other sites More sharing options...
Geoff Weeks Posted October 15, 2023 Share Posted October 15, 2023 I really liked the idea, Never ran one, so don't know how they did in service. It allowed an intercooler without re-designing the nose/ radiator placement. Same reason Cummins used the low flow cooling for a few years. In the end Ait to Air charge cooling with the cooler in front of the radiator became the standard, but it did require a re design of the nose for it to fit, Mack and Cummins could allow their higher power engines in trucks that weren't originally designed for them. In the end, everybody went to the air to air in front, so these "work arounds" lost their reason for being.

Geoff Weeks Posted October 15, 2023 Share Posted October 15, 2023 BTW how long did the tip-turbine stick around? I thought of them as a 70's and may be early 80's thing, but have no idea when they were phased our.

mrsmackpaul Posted October 15, 2023 Share Posted October 15, 2023 I reckon mid 80s you could still buy them in Australia Notice the R model tipper shown is NewZealand built Paul Quote Link to comment https://www.bigmacktrucks.com/topic/73425-mack%E2%80%99s-tip-turbine-was-ahead-of-its-time/#findComment-540360 Share on other sites More sharing options...
BOBWhite Posted October 15, 2023 Author Share Posted October 15, 2023 Anyone know if tip turbine engines were ever used for marine use? I would think that an intercooler on the engine would be nice on something that doesn't have a traditional radiator like in marine or irrigation motor use.

Geoff Weeks Posted October 15, 2023 Share Posted October 15, 2023 Kind of a step back from marine use. Marine has access to an unlimited heat sink, so water aftercooler make more sense, Quote Link to comment https://www.bigmacktrucks.com/topic/73425-mack%E2%80%99s-tip-turbine-was-ahead-of-its-time/#findComment-540374 Share on other sites More sharing options...
