Pics or it didn't happen, is that your point (logic)?

Like I said in another post (club Fox) I used the timed lap to measure my performance changes during my engine development. As it was pointed out, photo equipment often had too much variability to be of much use in the 28K to 30K operational range (26k RPM on the ground). I think I have some development junk in my junk drawers but these looks like most other trashed engine parts.

I hate to say it but, I wasn't clairvoyant when I sold the engine. I had no idea that the pilot was so good that he would drag my engines into a national title! Sorry no photos exist in my collection. The AMA magazine (NATS coverage for 89) did show part of one of my engines. If you find it please post it.

As I recall it would look like a thin walled Picco/OPS engine. (Lots of port bumps on the outside.) I modeled this after a long sprits (I think Jack)driven conversation with Henry Nelson at the 86 Rough River 1/4 midget races in Kentucky, that we were attending. OK, I just kept my mouth shut and listened to the words of the master. Something that could benefit all of us.

This is way off topic as the OP is interested in pattern engines!
