What's the ETA for the oil feed line assembly? I'd like to use it when I install my BBK Full.

 

I don't think you need it on the Full, but I guess it couldn't hurt! (or could it?)

 

Everyone keeps commenting (on like 3 threads) about the new oil lines. Any details on the "revised bearing package" yet? This should at least be something we should discuss, no?

 

Ahhh...good question...I would like to know that as well...

I may try and give you a call after work Chad...

 

By taking some oil from the main line, there's less to go everywhere else, so in concept, the new feed line could mean a little less oil going everywhere else, but I think that CBRD must have assessed this possibility.

 

the CBRD oil line kit will most likely be similar to the FP kit. Same issue...same solution.

 

Just a thought…..has anyone tried increasing the volume flowing to the cartridge instead of the pressure? if I understand the construction of the turbo cartridge correctly, it has somewhat similar of a setup to a “piston ring” form where it withholds the oil in its place for lubrication. So my thinking is, if u increase the pressure, wouldn’t that increase the risk of leakage thru the ring? but higher volume will help eliminate starvation? …..might be totally off here..lol
Cheers!

 

With the size of the housing I don't think its possible to increase the volume flowing to the cartridge...I may be wrong as well...

I have always thought it was interesting that larger turbos (T3, T4, 30 & 35R & bigger) can have their oil feed line coming off the stock location on the head but these larger stock frame turbos need the oil feed line to come from the filter housing...

 

It is my understanding that the larger frame turbos have ball bearing cartridges, instead of journal bearings, making them better able to withstand the rigors of a extended periods of on-boost, like you would get on a road course.

 

True...forgot about that...good point...

 

Can you let me in on why you decided on the full instead of the b? I know spool difference, transient response etc, but with your level of knowledge on evos I am curious what led you to this decision. I was set on the b, but now you are the third person I have seen go with the full, any info you would share would be great. Thank you sir.

 

My reasons are probably not typical. I got a good deal on a used BBK Full (scheides'), and when I heard about the BBK-B, I contemplated getting my Full upgraded to a B, but after seeing the kinds of gains that are possible with little or no loss in spool from some of the new tubular manifolds that are hitting the market, I decided that a Full with a tubular exhaust manifold would be a killer street combination for a reasonable cost. A new BBK Full + tubular manifold is a bit more pricey and harder to justify vs a BBK-B with a ported stock exhaust manifold.

 

Very good points there sir...I've have been reading up a lot on all the tubular manifolds coming out...Looking forward to your results with a BBK Full & Tubular manifold...Any ideas on what manifold?

 

I think the focus with the new kit is cleaner oil to the bearings and higher oil pressure which can be restricted inline to desired levels until perfected. If the head oil feed line is capped, the quantity of oil to lubricate the rest of the engine will remain the same (unless the new line is significantly longer than oem).

FiD, ToxicFab (although not clear that he is going to market it), and Fortune Auto all look nice. The first two are equal length while the Fortune Auto is not. All have documented significant gains. The FiD has an awesome collector setup with the tubing aiming into the turbo at as optimum angle as possible.

Agree that since the line coming off the head would be capped, there should be close to a zero sum effect on oil distribution through the engine.
