Dumbo The Flying Elephant

Larry Hill · 02-01-2021, 09:39 AM

I should know more today after I leak check it. What I did see with the large runners and the injectors straight above them was the engine makes a lot of condensation. Water collected in the low spots in the head. Valve adjustments stay put, I had all valves within.001 of target.

Time for hand therapy, got to go.

The leak test showed all valves leaking in the 13 to15% range. I’m wondering if the seats in the heads moved or every valve in it is bent from the trans letting go on the 1-2 shift at Indy points race. Why are learning curves so expensive?
On the positive side the valve lift is a little short and a new cam with a tick more lobe lift will get us to within .005” of maximum lift. It may help power.

Progress on my hand is good now, after only 15 minutes of therapy I can put it flat on a table or make a fist. I can use it for a few things around the shop.

We were able to secure a major building block for the future of understanding on learning how to make power. We have three more weeks of racing then we will be home and get Dumbo to the paint shop to fix a fender that got rubbed on in the trailer.

Relating this to the outcry of frustration when my 7yr old grandson is forced to shut down a computer game session by his parents......”Ah man!!...Do you know how long it took to get to that level”?

Class mean nothing to NHRA so I’m done.

Larry, rightfully so, is clearly upset about the Divisional/Gators incidents and it would be a real tragedy if racers like him quit this sport because of crap like this.
