What happens in Vegas doesn’t stay in Vegas (AKA why I chose to run Accuair ENDO-CVT air suspension)

I finally received the new compressor for my air system so I figured I’d give a breakdown of the air suspension system I’m running in the Pontiac. I am running one of Accuair’s ENDO air set-ups as I wanted to keep my air suspension simple, quiet, reliable and easily engineered.

ENDO is basically a modular air assembly, allowing Accuair to scale their product up and down depending on customer demands. The full range is:

  • ENDO-T (tank)
  • ENDO-VT (valve tank)
  • ENDO-CT (compressor tank)
  • ENDO-CVT (compressor valve tank)

So, you can get a bare tank just for holding air (ENDO-T), a tank with an internal valve block which uses externally-mounted compressors (ENDO-VT), a tank with an internal compressor but no valves for on-board air (ENDO-CT), or a tank with both compressor and valves mounted internally (ENDO-CVT). These come in a range of sizes (3 gallon or 5), and in a range of coloured finishes.

Here are the colour options for the ENDO range.

Accuair launched the ENDO-T and VT at SEMA in 2016, which is where I saw it for the first time. They also showed a prototype of the CT and CVT which they announced they would release at SEMA 2017 (which they did).

Here is a video from Accuair explaining the ENDO-CVT concept: https://www.youtube.com/watch?v=0ebnrwFqHeg

I bought an ENDO-VT straight after SEMA 2016 as Accuair announced that, due to their modular construction, all ENDO products could be upgraded to CVT-spec later on. I can see why SEMA awarded Accuair product awards for the ENDO two years in a row!

While I’d have loved to wait for the CVT to be launched before upgrading the existing air suspension system in my car wasn’t legal to use on Australian roads, and really needed to be replaced. This meant I’d be doing the upgrade in two stages: firstly, fitting new compressors, height management, and the ENDO-VT set-up.

I have paired the ENDO air system with Accuair’s E-Level height management system. While it isn’t cheap at $1600 (AUD) E-Level uses height sensors fitted to each corner of the chassis to keep the car level and square. It also allows users to programme three heights into the touchpad controller (a phone-based iLevel is also available), and gives the ability to program the system to rise to a road-legal height as soon as the ignition is activated. This means the system can be signed off by an engineering signatory for road use in Australia.

Here is the ENDO-VT system with twin externally mounted Viair 480C compressors in my car. You can hear the compressors kick in at 19sec mark, even over the air orbital that Eric was using.  https://www.youtube.com/watch?v=1n3DvBwSEKQ

The fact the CVT runs silent and only leaves a tank on show is really attractive to me. I don’t have a show car but I want to drive my car quite a lot, so the OEM-spec Wabco compressor and lower maintenance compared to the old external compressors is perfect for me.

This is a traditional air suspension system, with externally-mounted compressors and valves. Messy, loud and using old tech.

Now, it isn’t cheap and you’ll spend approximately $1500 (USD) from Accuair, or $2600 (AUD) from Air Ride Suspension Supplies to get a 5 gallon four-corner ENDO-CVT tank set-up. This is slightly more than a conventional tank, twin compressors, and valve block, but works out better when you consider you’re not buying fittings, wiring and other ancillaries.

The silence and improved fill speed of the internal compressor is one of the main reasons I spent $1200 (Australian) upgrading from the near-new externally mounted compressors. I did manage to get $500 back from the sale of the two 480C units so it wasn’t a total waste, thankfully.

Here you can see the removable end caps and the ports which feed the valves and internal electronics of the ENDO-VT.

The CVT upgrade actually arrived yesterday, as I had missed the initial pre-order by a few days and, given Accuair were swamped with orders, it has taken time to clear the backlog. I have to say I am blown away by the quality of the parts.

I will do a full post showing how to dismantle the ENDO tank and convert it with the CVT upgrade kit when I am next at the car.
