My 818 has a short hose supplying oil to the turbo. The hose has a banjo fitting on both ends. One end of the hose has a larger banjo with a bolt that has two large holes - looks good. The other end of the hose has a smaller banjo and the bolt has a single tiny hole. I can't even get a 1/16 drill bit to fit in the hole. Seems extremely constrictive.
To my way of thinking, I need to turn the single tiny hole into two bigger holes, maybe even 4 holes. This seems painfully obvious - so obvious, what am I missing? Why would this hose "system" be designed this way?
For various reasons, I've lost faith in the previous engine builder (Speedy Roo Motorsports, Aurora, CO), so it's not unreasonable to think they dropped the ball.
Was it done to reduce the oil pressure at the turbo? Seems like if lowering oil pressure at the turbo was needed, that feature would be built into the turbo. And I've never heard of such an issue. The turbo is currently at Forced Performance getting rebuilt after spinning a main rod bearing. I've asked them the same question, but curious what the wisdom of this forum thinks.
