Hey guys!
I am struggling a little bit. I purchased an adjustable cam gear and was going to "dial in" my Boport 2.1 cam using the ebar method to ensure that everything was lined up right. I have included a link to a google photo album with my situation:
photos.app.goo.gl/8shsmMuyfjwmewaC7
If I line everything up and get all of the marks correct, the lobes appear to be 10deg retarded from what would be true TDC. I am currently running the car with the cam ebar-ed, which I guess would be 10 deg advanced from the "stock" location (and boy did I have to add some fuel to my VE map to get it to run right). Did I do something wrong?.
You can see in the first pics of the gear, the cam pin is properly located and the stock timing mark is just to the left of the 12deg retarded marker. This is how I lined everything up. I have yet to get the car to a dyno, but overall i don't want to do anything that will mess up my engine. It has been running fine, was able to autotune the fuel map where I am not running lean.
The other thing that complicates my situation is that I just completed a full bushing swap on the car. I changed the cam gear while I had it in the shop. While doing my project, I got a really good deal on a 8.8 rear end ($200) but it came loaded with 5.13 gears (my 7.5 had 4.10's), so the way the car is driving since getting back on the road has not felt like it did before just because of the gear change alone.
Bottom line: is the ebar method not a good thing to do with Bo's cams and should I adjust the cam back to the "stock" alignment? OR am I completely misunderstanding the ebar process and does that only work for other cams?
As always thanks for any help you can give!
