MACKS Posted November 15 Share Posted November 15 Just my two cents but u really don’t need this on your engine,back in the day every one disconnected them or put an air switch in the cab to shut them off,just take it easy on the fuel pedal and u won’t roll any black coal,once u have boost then u can put the fuel to it… Quote Link to comment https://www.bigmacktrucks.com/topic/74727-tip-turbine-boost/page/4/#findComment-562003 Share on other sites More sharing options...

Yes I do notice that the exhaust is clean after the turbo spools up and the engine produces very little smoke if i ease the the power on instead of just flooring it.

Popular Post Geoff Weeks Posted November 15 Popular Post Share Posted November 15 Wash down of bores is more a problem when and engine idles, you get incomplete combustion and condensed fuel on the cyl walls. 'Rolling coal" tends to get hard carbon build up above the top piston ring, wearing (scoring) the bores. Best way to prevent carbon formation is to burn with enough air for complete combustion. Neither are good for an engine. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/74727-tip-turbine-boost/page/4/#findComment-562012 Share on other sites More sharing options...

There doesnt appear yo be any shims on it at the moment but that doesnt mean a new one wont need to be shimed.I did see how to work out the shims needed but I forget..do you or anyone else know?

Thanks Paul Correct doubt if you can buy shims so if you can find a 9/16 flat washer slightly thicker than what is stamped on the pump you will likely be happy with your out come ! 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74727-tip-turbine-boost/page/4/#findComment-562152 Share on other sites More sharing options...
