Here are some closeup pics of the engine mount:

Jetbike Test Movie - July 2001, Golden, Colorado

On November 8,1998 the kart reached approximately 15 miles per hour. Speed measurements were made with a GPS.

In early October, 1999, the Kart was fitted with a piezoelectric ignition system, replacing the troublesome "model T" ignition coil. A nitrogen tank and regulator was fitted to the kart, improving tank pressure.

On October 23, 1999 the kart was tested with the improvements. The "barbeque grill tank" was replaced with a "forklift" tank which has both vapor and liquid ports. Top speed was still only 15mph, but reliability was increased greatly. The slow speed is attributed to the excessive weight of the tanks and the kart itself (low power-to-weight ratio). Anyone attempting to build a Jet-Powered Go-Kart is advised to choose a larger jet engine.

The power plant is a Gluehareff G-2-20 pressure jet engine. This jet weighs 5.5 pounds, has no moving parts, and is fueled with propane, generating 20 pounds of thrust.

The propane tank contains 20 lb of fuel, and additionally pressurized to 280 PSI with nitrogen.

The Jet was purchased assembled from Vortech, Inc. The Kart was purchased from Fairfield motor sports in Independence, Mo. Our engineers designed, constructed, and installed fuel and ignition systems, as well as a suitable mount for the engine.

Here is the tank. Notice the check valve on the right.

The inert gas regulator has gauges which show nitrogen tank pressure as well as propane tank pressure.
