WBA Blast Nozzles have the following benefits:
All our adapters are designed, engineered and manufactured
in house. Now in their 4th major revision, WBA adapters are continually
improved, updated, and refined based on FEA analysis, innovation and customer
feedback.
Our aim is to produce and provide the most effective,
durable and cost-effective product possible.
Manufactured in high quality branded PLA plastic, post
treated for additional strength and durability - NB. Colour may vary.
Thanks to our in-house design capabilities we are able to
react quickly to custom requests and alterations to existing designs. Do you have
a car not covered by our current line up? No problem! Want to 'click' your
nozzle on to a specific type of vacuum? Sure! Please get in touch with your
requirements and we will be more than happy to help!
There are excellent how-to guides on YouTube and
Bimmerforums that walk you through the process step by step and list the
additional parts you will need to carry out the job - Alternatively we may be
able to assist depending on location.
Please PM with any questions or enquiries.
Why clean my engine?
Car
manufacturers have gradually switched to direct injection (DI) over
the past decade and for good reason. Spraying a precisely controlled amount of
fuel directly into an engine’s combustion chambers results in improved
efficiency and greater power density; exhaust emissions are reduced as
well. In 2015, 45% of all petrol engines sold utilised direct injection
technology, a number that has only risen in the face of increasingly stringent
emissions regulations.
Despite the obvious advantages, this technology isn’t perfect. One of the biggest problems with direct injection is that the fuel is no longer being sprayed into the ports and onto the back of the intake valves. This mist of fuel actually helped keep the intake ports clean by preventing carbon deposits from being able to adhere to the ports and valves.
These deposits, if allowed to build up, can cause turbulence in the inlet tract, and this turbulence causes the air/fuel mixture to be unevenly distributed. When ignited, the flame front can be erratic, leave unburned fuel and create hot spots in the combustion chamber. On a scan tool, the engine may show a loss in volumetric efficiency. In extreme cases the localised hotspots that form in the combustion chamber can cause physical engine damage!
The symptoms of carbon build-up will usually manifest as;
· Misfire
codes, EML on dash.
· Stumbling
and suspicious fuel trim numbers.
· Noticeable
loss of power.
· Poor
throttle response.
· Poor
fuel economy.
· Lumpy
idle.
· Difficulty
starting.
For owners of these cars, the carbon build-up problem means they must invest in additional maintenance semi-regularly to have the carbon cleaned from their engine. Until relatively recently this involved manually scrubbing the posts with brushes and cleaning agents or in extreme cases even removing the cylinder head to clean the deposits in a chemical bath, both time consuming and costly.
The latest development and the process adopted by WBA and Enigma Motorsport utilises finely crushed walnut shell granules to shot blast the deposits from the ports and valves without having to remove the cylinder head. The walnut granules are gentle enough to not damage the soft aluminium construction of modern cylinder heads, but hard enough to remove all deposits, restoring your engines performance and reducing fuel consumption.
The photos show before and after shots of inlet ports walnut blasted by us, and show the effectiveness of this technique. If you have a direct injection car that has done over 50,000 miles, you’re looking to extract the most performance from existing or upcoming modifications, or you're having problems with fuel economy or performance we would love to help fulfil your engines full potential.
