How to plumb an air sensor into a silicone hose

Posted on by

We like to make life easier here at Viper Performance. Thats why we created a hose specifically for plumbing in an air sensor. This unique hose allows you to connect and plumb in an M10 air sensor directly into the hose. Ideal if you are modifying your air intake, or doing an ECU upgrade/re-routing.

Our Air Sensor Hose is not available elsewhere. Available in a choice of silicone hoses that reduce in diameter (transition hoses), or straight couplers with constant diameter, all featuring the M10 thread in the centre.

Used car values increase 13.5% in three months

Posted on by

Used car trade values are continuing an “unparalleled shift upwards”, according to Cap HPI.

CAP hpi’s daily Live trade values reported an overall increase of 4.8% at the three-year point during the month of June, equivalent to over £625 per car. This rise follows the 2% increase during April and 6.7% increase in May, signifying that on average, values have increased by a staggering £1,700 or 13.5% in the last three months. This rises to £2,500 for one-year old cars over the same period.

Younger cars, up to one-year old, have seen rises of £2,500 in the same period.

“Consumer demand has remained very strong in June, despite half-term, great weather, and Euro 2020 to distract people.

“With stock-turn high, this has led to retailers requiring a constant supply of cars to replenish their forecourts,” said Derren Martin, head of valuations at Cap HPI.

“Well-documented new car supply issues resulting from several component shortages, have led to fewer fleet returns and part exchanges. This has caused demand to outweigh supply for the third month running,” he added.

What is a JIC hose fitting?

Posted on by

JIC Hose fittings stainless steel pipesJoint Industry Council Thread – Commonly referred to as just JIC fittings are metal to metal sealing type fittings have a 37° flare (sealing surface angle. original design specification for the fittings comes from the Society of Automotive Engineers (SAE) and these fittings are the most common American fitting type in Europe.

Are AN and JIC the same?

Technically No. AN stands for Air Force – Navy Aeronautical Design Standards (also known as “Army Navy”) that are used in U.S. Military aviation applications. These fittings are made to meet strict performance standards related to the aeronautical industry.  Confusion between AN and the industrial counterpart, the SAE 37° fitting occurred. The Joint Industries Council (JIC), sought to clear the air by standardizing the specifications on this type of fitting by creating the “JIC” fitting standard, a 37-degree fitting

The majority of the hydraulic population agrees, the JIC (or SAE) 37 degree fittings are generally interchangeable with AN fittings. Generally now when people refer to JIC or AN they are merely referencing the 37 degree fitting.

The hose fittings on the Viper performance site are sold in AN-(dash) sizes.

How do I know my JIC/AN fitting size?

AN sizes are shown as a size number prefixed with a hyphen, so a -10 fitting would be called a “Dash 10″ AN fitting.

The number represents the OD (Outside Diameter) of the tube the fitting was designed to fit in the old AN specifications. The number represents the OD as multiples of 1/16”. Therefore, a -10 fitting was originally designed to fit an solid tube with an OD of 10 * 1/16″ = ⅝″ (~16mm).

BMW starts testing hydrogen-fuelled X5s

Posted on by

BMW has begun testing prototypes of the ‘i Hydrogen NEXT’. This will effectively be a hydrogen-fuelled X5. The X5s will be tested in Europe under “real-life conditions” as BMW gears up to eventually put a FCEV on sale, perhaps as early as 2025.

The i Hydrogen NEXT uses fuel cells developed together with Toyota and can carry six kilos of hydrogen in twin CFRP tanks. The fuel cell and “performance buffer battery” produce a combined 369bhp.

Frank Weber, member of the Board of Management of BMW AG responsible for Development, says: “Hydrogen fuel cell technology can be an attractive option for sustainable drive trains – especially in larger vehicle classes. That is why road testing of near-standard vehicles with a hydrogen fuel cell drive train is an important milestone in our research and development efforts.”
