More Tunnel Ram Help

Yes I have a link to Tom Vought's discussions. I believe he also mentions drilling this plug (I used a hose barb instead) to lean the mixture instead of drilling the throttle blades. This set up is working amazing, for me, how I drive and what I need it to do. I understand adding the power valve, more idle mixture adjustments, etc would help fine tune this, make it more efficient and possibly more power but it truly is working remarkably well as it is set. As for adding PCV hose to this port, I would have to think about sizing. Typically PCV is 3/8 hose while this is a 1/8 hose barb. Not sure I would gain much even reducing it and splitting it across each carb for a total of 1/4. Also, my thought was any oil film in such a small hose, it could become blocked/clogged easily.

So, I had thoughts to run the Demon at the drag strip just to see what it will do. Trying to stall the car (foot brake style) then floor it, it was not happy. Large bog. With the 660's not having anything from the factory other than 0.025" squirters, I ordered 4 (2 per carb on center squirters) and drilled 1 set to 0.031". This solved 85% of the bog. I then redrilled to 0.033" but due to weather, I have not been able to retest.
