Oil Cooler Adapters

[Joe_Rocket]

Looking for a oil coller adapter...

For mostly street use and occassional track day., do I want to remove the factory bypass adapter and always have filtered oil or keep it? Why did they design the bypass in the first place, and is there any negative effects to running without the bypass?

Thanks.

If it will fit I am getting ready to pull the oil cooler adapter off my 95 LT1. I am in need of a regular filter mount though.

The best bypass and filter relocation parts on the planet were actually designed by TRACO Engineering back in the 60's and used by all the top teams back in the day. The design was so good that, every one has tried to copy it and still does (Moroso, CV, Winters and others) but nothing still comes close to the quality as the original TRACO stuff. Until......... CV Products came along (THE major NASCAR supplier to engine builders) and changed the game with their CNC'd stuff for an excellent price. Not to mention the added features that are available today. Like external oil pressure adjustment, build in thermostats and a pile of other stuff that you or I would never use, but its available if you were to need it.

The bypass was designed for a few reasons. One, was to make it eaiser for oil cooler installations; two, was to move the filter to a remote location for easy filter changes; three, was to add more capacity to the oil system and it was also used to aid in the fitment of some of the other engine peripherals such as header and steering systems and to adapt some of the earily dry sump oil systems.

Well since TRACO was sold off in the middle/late 90's, JJ has re-opened "TRA-CO" Racing Engines (just after his stint as the Engine program manager for Reeves Callaway) because he missed it so much. I believe he is once again marketing these, and they even have the vintage thing going for them, but they still to this day look totally bitchen. They are also still available through AVIAD Competition Oil Systems out of Chattsworth California.

AVAID part number: 40104 for the bypass / and 40103 for the filter mount.

Negative effects to NOT running a bypass device ?? Yes, there is. If the system gets clogged for whatever reason, it is possible to over pressurize the oil system and blow the filter wide open. Most of the systems (bypass type) use a filter relocation device to aid in mounting a larger performance or "racing" type filter to this system. The filters by themselves basically up the burst pressure strength to around 500 psig for the filter alone...... but the rest of the system has to be up to snuff as well or it will be the weak link.

Thanks Chicane67. That was very informative.

So, does the factory bypass only come into play with above normal pressure, so most of the time the oil is being filtered?
