Air Jacks / SR3

[dptdpt]

After a few years of entertainment in it, I've sold my Clubsport and now am looking forward to getting my SR3. It comes with air jacks and I'm wondering what others use to provide the compressed air. Radical told me to talk to BOC but they will only rent a 3ft cylinder at £10/month.

Is this what I should do or is there a better way?

I have a set of diving bottles at present, but was looking into buying a high pressure compressor/ scuba compressor (normally used to fill diving tanks)

I have a dive bottle which I bought new and a petrol dive compressor for filling, which I happened to come across on racecarsdirect one day. They appear from time to time but aren't what you'd call cheap even used. I think I paid 700 for mine but they are often over a grand. You'll need an appropriate adaptor if you go this route. The compressor is a Paoli one but it's only a rebadged dive compressor.

My local Scuba shop refills for £3, so apart from the inconvieience of having to take it there it doesn't seem worth buying a compressor.
I suppose it depends on capacity but how frequently do you need to refill?

[ric355]

I have a single 12 litre bottle. One fill up to 205bar will be down to maybe 180bar after a track day if I change tyres a couple of times. That includes running the air gun for centre locks and maybe some tyre pressure changes. I always recharge the cylinder before the next event.

The reason I bought the compressor was for convenience, but I also bought it knowing that I'll easily get my money back if I sell it. It's the same reason I have my own tyre changing machine as well.

Thanks for that. I guess I'll buy a bottle and have it recharged, and look out for a cheap compresser in the meantime.

Don't forget you'll need a 30/300 bar regulator, high pressure airline (regular domestic stuff isn't rated high enough usually), and a lance if you don't already have it.

Try CES Europe. I bought my kit including bottle trolley from them. It is expensive but its top notch kit !

All fixed up from CES
Very helpful

Unless you are doing endurance races, strip them all off and sell them, saves weight, saves the hassle of air bottles and e you'll get enough cash for another set of tyres

coming in late to this, you will still need to carry a low level jack as a minimum. ideally a trolley jack as well,,,,,,no air ( or a leak as we found ) means no lift...

Agreed, but when the work they are excellent - even on a trackday if your on your own - they save you alot of labour and hassel - yes you need a back-up plan.
