AZB755V8 Posted August 15, 2019 Share Posted August 15, 2019 3 hours ago, Mack Technician said: Nothing left but the crying on that unit. Liehberr abandoned that engine and went back to one turbo now. Yep... One turbo with the new technology is more than most diesel engines can deal with. I try and talk guys out of turning things up. It can be done but at a substantial cost in parts and time at least with a big diesel. Want to tweak things get an old 350 Chevy and play. There are books written on all that can be done and it works, most of the time. Parts are cheap and available in a day or two at your door step, not so with a Mack. I like big power and have several 1000hp rides, one is my Superliner. It is crazy and no one can use that power for more than a short amount of time. Then have to work on it for hours to do it again... but it is fun at least for a while. Yes there has been heads, pistons, liners, bearing, blocks and turbos scraped in the carnage of fun. I just don't nail it much any more to have "fun" working on stuff like i used to. I just what the stuff to stay running now. 👍 Quote Link to comment Share on other sites More sharing options...

Maxidyne Posted August 15, 2019 Share Posted August 15, 2019 Scania is still largely "BEFORE SCR"- Only the top 730 HP rating uses EGR. https://www.scania.com/global/en/home/products-and-services/trucks/our-range/v8/specification.html 1 Quote Link to comment Share on other sites More sharing options...
