What any racer worth his salt, knows that set up helps the drag torque coefficient factor, you know.....bla bla bla.
The drag coefficient is a number that aerodynamicists use to model all of the complex dependencies of shape, inclination, and flow conditions on aircraft drag. The drag coefficient then expresses the ratio of the drag force to the force produced by the dynamic pressure times the area. So trunk 2x4x 4 doors ='s fast.

I always liked the drag coefficient right across my face when I'm flying
Hmmm, it seems we all are into drag coefficients. It's not a great concern to me anymore, since I don't shoot at anything past 600 yards these days, but I still pay attention to it. The drag, or ballistic coefficient of my butt is somewhere around .02 now. And the drag coefficient of my 502 build is at -540 right now.

LOL Mike I like tracer bullets now that I'm older so I can slow walk it in there
Oh, when I was at the engine machine shop today, I asked Don if I should drill a small hole in the driver's side lifter bore gallery plug. He said absolutely, he does it on every applicable build. I also asked him how much that would reduce oil pressure. He said it won't make enough difference to register on the gauge. I figure a roller camshaft with fairly aggressive lobe profiles has got to be hard on distributor gears. And since that plug is right there at the gear....well you get it. I rigged up a fixture to hold the plug in the lathe. Bout to drill it out now. I'll post pic of drilled out plug, or a pic tiny broken drill bits.

That sounds like a great up grade . Didn't you say you upgraded the distributor gear also?

Is that you in that plane?
Yeah, I'll be using a hardened / melonized steel distributor gear. Pretty much have to with a 1055 steel roller camshaft. A regular ole iron gear would destroy itself and the camshaft's gear. It's funny, just to be thorough, I remember emailing Lunati about which gear to use. The guy emailed back, "Use a stock gear." He's so young, he had no idea that stock distributor gears on prehistoric engines were made of iron. Another Lunati tech emailed me with the correct answer.
You could use a bronze gear, but they wear out quickly. I haven't had any experience with newer composite gears, but they're supposed to be the shizzle.
The plug was so hard, I couldn't scratch it with a center drill. I annealed it, then everything was good. That's a .030" drill bit. Dang thing is so small, I had to wear reading glasses to tell which end was the working end.
What a PIA but well worth it, Good plan I'll have to remember it when I get that far. Tracers
Is that you in that plane?
No but I have flown one like that and the PT-17 Stearman it's civilian counterpart for about 5 years in the late 80's I have pics of that Was way into it. Me and a buddy had a rented a hangar and were refurbishing the Navy N3N's which were the military version of the PT=17 Steerman Biplane a spruce and canvas plane. Fun times. I Learned how to work on the Pratt Whitney 450 hp 9 cylinder air cooled rotary motor.
Those radial aviation engines are so interesting. It seems like such an inefficient setup, but necessary for packaging. But dang they still produce power!
Redroad, here's some fun from this afternoon. More evil Mikey. My lady friend and I were out joy riding, and I saw this cornsnake. She bout had a stroke when I locked up the 35" tires under that little Jeep.
Very cool ! What a beauty. I can relate to your passenger being taken back. I was up in Traverse city Mi visiting my Anishinaabe brothers . A couple of us went on a hike and we came upon a clear spot in the tall grass and there was the biggest snake I'd ever seen here in U.S. it was black and over 6' long and thick in the body.when it saw us finally and scurried off it made the 5' tall grass wave like a stiff wind had hit it. It was a "Blue Racer" haven't seen another since. When I was down at Ft. Polk I saw Water Mocassins and by us we have Timber rattlers but we don't see them very often.
