A roller bearing turbo for a 5. 9 you say.....
This is no secret and is and has already been done by a few so ATS is no the first to begin testing on them,but,may be the first to market them. The is a major manuacturer out there who has had 3(I think this is a correct number,but,I'll check)roller turbos and their specially designed better flowing exhaust manifolds on 2 of their house trucks and one private individuals. They were shelved for production at the time due to costs of the manifolds(searching for a more cost effective production of them) and the company wanting to wait till a later date as to make them not out of reach price wise for the public and causing them to invest a large sum of money to which they may not recoup. So,now its a wait and see deal,a call recently to my contact has told me they will be coming sometime this year,when he would not confirm.
One other one I do know about is one on a mildly tuned 12valve. It was done by a gentleman who does not run in diesel circles and was his first one. I know the gentleman who has it and it now has over 35,000 miles of daily street abuse and has and does perform flawlessly.
It will be interesting to see what becomes of the roller parade and how it will effect the turbo market and those companies who now do custom turbos for our trucks. Longevity,who knows,just like the hybrids were,bolt them on,abuse them,break them upgrade them and move on to a better product. Same game,different product... ... ..... Andy
