actually I'm really really interested in your twin setup Jeremy. How is the longevity on the oiless turbo's?
Better than oil fed turbos. They have no seals to leak and then need replacing, no oil to carbonize and coke up in the bearing housing from heat. The center sections are aluminum so run cooler, and the watercooling via waterjackets is leaps and bounds better than oil cooling only. Comp states you can extend the ceramic bearing life indefinetly by having them greased at proper intervals. For a street car they reccommend 3 years 36k miles to have it cleaned, inspected and regreased. Price to have them serviced is $200-300 which is very affordable. In 2 years I had to have my oil fed turbos serviced 3 times for oil seals. I will never run an oil fed turbo again.
