@hacked89 i watched your 7/1 video you posted. You talked about how you did the CDR modification, but not the why.

I assume it’s an experiment to not have a catch can. What are the shortcomings of the factory system? Is it the rear 2 cylinders getting fed all the vapors?

Thanks for your time.

On the T04Z truck, I’m running a catch can. It’s working, but I feel that it is unnecessary. That truck is decently capable, being fed with an R&D 130cc. It has 5000 miles on the build and 2500 mile change intervals is seeming about right so far. For that truck, it has a v band intake manifold which is nice because the factory CDR port is deleted and I feed the system back through the air intake tube. On the bronco, I used a factory intake and wanted to try no CDR which left the port, and figured I’d do a hybrid and run the valve covers to the factory port location. This is only because it’s NA. At one time, and I may have posted about it, I read that there was international documentation that when CDRs failed open it pulled towards the rear cylinders and was a cause of head gasket failures. I may have even speculated that in my past post history. At this point, I don’t think it’s an issue and may have been a rumor. Talk is cheap though and anything I suggest or say unless it’s disclaimed I put to the test on my own stuff. The bronco engine is testing that. Lastly, I want a version that works well for both NA and turbo. i think IDIot and R&D have the right idea to pursue it off the IP cover. That’s what I’ll tinker with next. Im going to be working on TIG skills this fall / winter because I have some current and future projects that will need it.

Thanks a ton!

For the rear, I want an f350 19g tank to bolt in. I looked at a bricknose f series frame, measured and the bronco frame and it’s almost as if ford just chopped the f series frame short for the bronco. I air hammered out the rear frame cross member rivets and moved it about 4” to the rear which will give me 29.5” between cross members same as an f series truck. Currently mocked up. For off roading, the 19g tank is nice and tucked up under the chassis.

Additionally, I welded and mocked the front end up for now and installed an f350 receiver in the rear.
