1. When you are ready to have the Surbo installed in your vehicle, please call your local dealer. Contacts are available on our homepage (click "Surbo's Main Webpage" below). If you cannot find the contact, do not hesitate to email us for help.
2. The Surbo is tapered from 2" to 2.5" in diameter and nearly 4 inches long. Ring adaptors or housing (which adapt the 2" inlet of the Surbo to the diameter of the air intake channel) will be shown to you, the customer. The underlying principles and activation method (see How It Works ) will be explained.
3. The dealer will inspect the engine and show you where the Surbo will be placed. Depending on the air filter layout, which could be original or already modified, the Surbo can be fitted at the inlet to the filter case, or at its outlet, or in the air pipe after the filter. No cutting will be done unless it is absolutely necessary (which is seldom the case). An air line check will be performed, and broken air hoses will be rejoined (if any). In short, all the air to the engine must be channelled through the Surbo.
4. The Surbo will be installed and leaks between it and the manifold will be sealed with high temperature resistant RTV silicone to ensure air pressure. (It will still be possible for you to change the air filter without affecting the setup as there is the original rubber seal for the filter cover.)
5. After the silicone has skinned in 15 minutes with hairdrying, the dealer will go with you for a test drive of your new Surbo car, and confirm that it is working perfectly or even demonstrate. Only when you are satisfied will payment be collected.
So, call your local dealer to put a Surbo into your car soon.
When buying a Surbo:
1. Use just one Surbo first in your vehicle, be satisfied that it works as claimed, meaning the installer did a good job (with no air leaks). This is especially important if your vehicle is automatic and has much less usable power than a manual vehicle. To supervise the installation yourself, look at the diagram below for the single Surbo. For the Surbo to work, all the air must pass through its centre, so proper sealing is necessary. Check that the Surbo's round inlet end is sealed (using rtv silicone or pvc pipe glue) with its rubber adaptor or the main hose pipe, and all pipe joints even if they seem to be tightly clipped are sealed to prevent air leaks. All minor vacuum hoses have to be airtight as well. The oil cap must be tightened and oil dipstick also tightened at its o-ring seal with thin masking tape as they are both air-connected to the Surbo. No other air pass devices should be used as they will cause the air to run around the Surbo. This way, the Surbo becomes ONE with the engine and it will be able to compress the air. As an option, the purge tube (see the lower diagram) can be stopped and sealed both ways to maximise the air pressure.
2. Read the page on How To Use The Surbo to reap the maximum benefits.
3. Then, if you want more power in the form of a Twin Surbo, you can ask the installer to add another Surbo in a straight line only as the two Surbos must work together, where space allows (see the lower diagram above).
