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

Esprit de hardcore: Pismo Race of Gentlemen 2016 – Daniel Beaudry Hemmings

West Coast Race of Gentlemen

West Coast Race of Gentlemen

 

On October 15/16th this year the inaugural west coast version of the Race of Gentlemen took place at Pismo Beach.

Having been to Pismo a few years ago it’s an ideal spot, the beach is great and it’s a real “car hobby” area.

Unfortunately and ironically the weather wasn’t at all kind to the event, and it may be that it ends up being a one off?

A Closer Look at the Bonneville Salt Flats in 2015 (Hemmings Daily by Daniel Beaudry)

An excellent article on the current state of the flats and it’s long history by from Hemming Daily published on September 29th 2015

Bonneville Salt Flats A Closer Look

Due to mining and various other reasons it would appear that the Bonneville Salt Flats are unlikely to return to former glories..

Why Hot Rods are the Best Thing for Social Media

Hot Rods are Social Media’s Fuel according to an article by David Kennedy over on Hot Rod Deluxe. I’d say he’s partially right if you take a look at the range of pictures across Facebook and Instagram etc.

Cars in general,and especially American cars with all the various sub genres and cultures probably formed one of the earliest “Social Networks” before there were such things!
