Bring this back from the dead. Im going to swap out the compressor and tank for a carbon bottle on my GT setup. What are you using for air? Nitrogen? what is the proper psi the Gt actuator wants to see? Thanks

I'm using low pressure nitrogen bottles and this compressor to get the high pressure needed for the on board tanks:

works great.

Also, feel free to call Nicholas Belling with XLR8, I think he does most (all?) of the north american geartronics importing and service. He's been very helpful as I've gotten my Geartronics stuff sorted out:

I'm using Ninja 68 cu in bottles and a Yong Heng 4500 psi air compressor from eBay.

I went with those bottles because that's what Gary included when I bought my car from him, so I just got a few more of the same.

The compressor was a bit more of a risk, but it seemed to have good reviews, and I've been pleased with it so far.

I tend to spend few more bucks and buy the product that is designed, assembled and uses at least some US sourced parts. You are supporting your fellow Americans, customer service is better and you are not supporting a communist empire. But that is just me......

I think I was one of the first to pioneer the use of HP Nitrogen bottles on the Geartronics. Prior to this everyone was using a compressor which led to problems later on. I machined some cool brackets to mount the blipper cylinder which XLR8 sourced from me.

The pressure from the bottle needs to be held at a consistent 800 psi then a second regulator that maintains 125 psi.

I had a pressure switch on my regulator tied into my EVO4 logger that let me know if the regulator was functioning at the right pressure. Not really needed.

I ran 5 full season with 6 bottles. Even at the the Runoffs where we were doing multiple test days and 4 Q sessions I only had to refill my bottles one time. I would always put a fresh bottle in for the important races it was one less thing to worry about.

I could do an entire test day on one 68 cubic inch bottle at 4500 PSI. This size tank was more than enough volume and the packaging was easier.

Rather than using a secondary compressor to get the 2000 psi tanks up to 4500 in your bottle, I rent a 6000 psi nitrogen tank from Airgas. It is a specialty item meaning that you have to special order it but it is fantastic. Advantages: easy and quick refill of bottles, you dont even need a second one, no air is introduced inti the system, no expensive and failure prone comressors which need cooling, etc. Cons: the tank is very heavy and you need a specialty fitting from tank to regulator. I pay about $60/month for tank rental. Highly recommended.

Gary what secondary regulator do you use? Thanks for help
