Brownsburg or Avon?

They are moving it to Nebraska? I read in the article. Maybe i am wrong.

OH YEAH ! Those were some badass engines.

The Offenhauser:

One of the keys to the Offenhauser engine's success and popularity was its power. A 251.92 cubic inch (4,128.29 cm³) DOHC naturally-aspirated four-cylinder racing Offy with a 15:1 compression ratio and a 4.28125-by-4.375-inch (108.744 mm × 111.125 mm) bore and stroke could produce 420 hp (310 kW) at 6,600 rpm (1.77 hp per cubic inch, 81 kW/L) making it remarkably power-dense. Other variants of the engine produced even higher outputs of 3 hp per cubic inch (137 kW/L), unparalleled for their size and capacity in power-to cubic-inch/cylinder-count ratio. Another reason for the engine's success was its reliability. Its monobloc construction made it immune to head gasket or cylinder stud problems, and allowed for higher cylinder pressures.

From 1934 through the 1970s, the Offenhauser engine dominated American open-wheel racing, winning the Indianapolis 500 27 times. From 1950 through 1960, Offenhauser-powered cars won the Indianapolis 500 and achieved all three podium positions, winning the pole position in 10 of the 11 years.

Offenhauser produced engine blocks in several sizes. These blocks could be bored out or sleeved to vary the cylinder bore, and could be used with crankshafts of various strokes, resulting in a wide variety of engine displacements. Offenhauser (and Meyer-Drake, in later years) frequently made blocks, pistons, rods, and crankshafts to specific customer requests. However, certain engine sizes were common, and could be considered the "standard" Offenhauser engines:

97 cu in (1.59 L) - to meet the displacement rule in many midget series
220 cu in (3.6 L) - displacement rule in AAA (later USAC) sprint cars
270 cu in (4.4 L) - displacement rule for the Indianapolis 500 under AAA rules
255 cu in (4.18 L) - for Indianapolis (during the 1930s fuel consumption rules)
252 cu in (4.13 L) - displacement rule for Indianapolis under USAC rules
168 cu in (2.75 L) - displacement rule for turbocharged engines at Indianapolis (to 1968)
159 cu in (2.61 L) - displacement rule for turbocharged engines at Indianapolis (1969 and later)

NBC Sports APP.

You’re Welcome.

IIRC Mid-Ohio is Bobby’s Home Track.

That’s neat, should’ve camped out and watched the work on the cars😁

Graham got very lucky to get this ride. He drives for Honda and there were some Contractual hurdles that had to be handled because the Ride he was offered is a Chevrolet but they figured it out.

To Win first you have to be in it !

You know that he’s Married to Courtney Force (one of John Force’s daughters) and they have 2 children.

[Grammy]

Yes, Mid-Ohio was Bobby’s home track, and we were close enough to see races there for a number of years. We also saw several at Watkins Glen and Road America. Great fun, but definitely for young people! Sooooo much walking!!!

I didn’t know Graham was married to Courtney. We pretty much lost touch with the sport for a number of years. This year we have been watching the races again.

[mabarker1]

I can only imagine what their kids are going to do when they find out what Grandpa John does for a living and they see all the videos of him blowing up the Funny Cars over the years.

Our town is Danville, once home of the .Mayberry in the Midwest Festival. CoVid killed it for 2 years and then when it was time to start it again, the town council nixed it. They’ve all been voted out now, so there’s hope to have another one next year.

I th8nk of .Danville as a suburb of Avon, and Avon as a suburb of Indy. We are equidistant to Avon, Brownsburg, and Plainfield, though, and could be considered a suburb of any of these.

Rahal’s car won’t start !!!

[mabarker1]

Behind the wall, can’t find the PIT CART and it’s got the spare battery on it and that’s what is needed to fix the car !!!!

IMS has installed Wind speed and direction indicators on the turns.

GREEN GREEN GREEN

[mabarker1]

Rahal running joining the race 2 laps down.

[mabarker1]

The wind indicators are at track level.

[FamiliarFace]

That’s crazy! Hubby said he wants to just watch it tonight. He tried to get around the blackout, but it wouldn’t let him. So I probably won’t check this thread until later in the day, after we’ve seen it.

[mabarker1]

OK, just curious if Y’All tried using the NBC Sports App ?

[38special]

A bad pit stop cost the #14 some time and a fine.

[God luvs America]

Luckily that tire just got over the grandstand. If the tire went into the grandstand several people would’ve died. That was the most dangerous part of that accident and the NBC crew barely touched on it.

[FamiliarFace]

It was on Peacock but blacked out for us in our zip code (Indy area).

[38special]

They’re having a little trouble finishing the race

[FamiliarFace]

Don’t tell me anything! We are about to get to watch this greatest spectacle in racing! :)
