Joe Jagersberger (Rajo Joe) Hot Rod Pioneer

img_9761
Joe Jagersberger came to the USA from Austria and began working for Case Corporation in Racine Wisconsin to assist in developing a race car programme.

Whilst working for Case Jagersberger was a regular race competitor including racing at the Indianapolis 500. He continued to race until 1911 eventually becoming victim to a career ending crash after which he spent several months in hospital and resulted in an amputation of his right leg.

Despite his injuries he continued to work at Case as a consultant. He continued to design cylinder heads and other peripherals eventually starting his own company under the famous Rajo brand. The name of the brand was formed from the RA of Racine and the JO from his first name.

Rajo started off by producing spark plugs and various other items. They then moved into producing  performance cylinder heads for Ford Model T and Model A cars.

The first design was the Model 30 which had 4 exhaust ports and one intake port all on the right side of the head. The Model 31 had two intakes on the right and four exhaust on the left. The Model 35C, first known as the “Improved Rajo Valve-in-Head” and later as the Model C had two intakes and three exhausts on the right. The Model A used the stock intake ports on the block. It had two exhaust ports on the right. His Model B two intakes on the right and four exhausts on the left. It came in three versions. The BB featured a higher compression ratio and the BB-R also included two spark plugs per cylinder.

He also offered a modification to the 1941-52 Chevrolet “stovebolt” L6 OHV 15 bolt head, which added another set of 3 intake ports above the 3 originals, to permit adding (an) extra carburetor(s) on a separate manifold.

Jagersberger died in 1952. The company closed in 1980.

Rajo equipment is still very much sought after and command very high prices amongst the traditional hot rod community

Being that I own an Xtreme it was interesting to look back at a review around the time of original release.

It comes out well, and IMHO is still a really nice vehicle, but then I would say that!

Pair of display Chevrolet V-8s include a little bit of New York World’s Fair history

After the end of the 1964-1965 New York World’s Fair, many of the displays that captured the attention of hordes of visitors either were destroyed or left behind to burn or weather away under the elements. A handful still exist, most notably the giant U.S. Royal tire-shaped ferris wheel, as well as perhaps one of the most significant GM displays from the fair, a cutaway 427-cu.in. Mark IV big-block V-8 that will head to auction next month in the city in which it debuted.

What a real shame this is, the Biscayne was the owners first car and the condition showed the amount of work he’d had lovingly put into the car. Not only was the Hellcat driver drunk, but I’m pretty sure it will be the tip of the iceberg in terms of too much car and not enough driving ability around the latest generation of muscle cars…

Got to feel bad for the owner of the Biscayne, as you can imagine the insurance probably won’t pay out.

On the upside the Hellcat may be crushed!
