Any news from the Chicken Coop Dyno?
« on: August 14, 2020, 10:19:27 PM »
Was 104* on my back porch today, just wondering if all the heat was from Jay's dyno session with the new heads making lots of heat?  8) ;)  Joe-JDC

I was wondering the same thing. He’s been kinda quiet lately.

I was just up there at his place, he's working away... Don't want to speak for him but I don't think it will be too long now.

Since you asked, preview of coming attractions:




Still lots to do.  My paranoia about potential problems and my inexperience with a really big cam (0.880" lift), and really big springs (1000 pounds over the nose) has slowed me down; Lykins steered me straight on some of that.  Plus, assembly of all the components led to one major surprise, where I discovered that I had calculated the rocker arm ratio incorrectly during the initial design phase over a year ago.  So, the rocker ratio has turned out to be high (1.85:1), and the pushrod side of the geometry isn't quite right; sweep across the valve tip looks good though.  I'm going to try to run with those rockers anyway because I still have good piston to valve clearance, but if they turn out to be a problem I may have to machine the corrected versions and run those instead.  Also, I had to modify some machining programs for the intake adapter to get clearance for the rocker arm support bar, clearance for the angled intake pushrods, and valve cover fit.  But I finally got it together and on the dyno on Thursday this week.  Building headers now, and also need to work out the linkage for the 2X4 manifold, mounts for the individual coils, and a myriad of other smaller details.  But I'm getting closer.

No promises on when I will have results yet, by the way, I'm fully aware and almost expecting that there could be problems on the dyno.  The whole top end of the engine is new and untested, so there may be details to work out...

Man, that's a ton of work!  I'm sure it will be worth it.  Best wishes for a successful light-off with minimal fuss.

In my sick little brain I have a picture of Freiburgers jaw hitting the floor at the next Drag Week that you unveil this setup.

Ha!  Especially if I put it in a Pinto LOL!  By the way, the header tubes are 2" to 2-1/8" to 2-1/4" stepped headers into merge collectors that I got from Blair, with 3-1/2" outlets.
