how much power can you get through a sprint gas ring systerm on both petrol and gas? I know we are restricked by the opening of the mixer ring and was after the type of output have got through this systerm.

Thanks heaps norton

My old EL topped out at 133rwhp on LPG and 136rwhp on ULP on the dyno.

It had the Sprintgas vapour draw system like you are asking about.

Thanks mate
What do you think is the most that this systerm is able to produce with the right cam and tune exhaust and such? 4l im talking about
thanks again

Hard to say.

Mine was stock other than Pacemaker headers and a CAI/K&N filter setup.

I reckon that a cam and head package would raise the power, but the restriction of the gas ring is the unknown factor here.

I have seen other rings around, that appear to be larger, which may allow more air flow and therefore more power.

I had a standard intake setup apart from the box; which had a hole cut in the bottom to breath in air from the hole in the chassis below where the supercharger pod connected in behind the front bar, snorkel (lips filed smooth), standard filter (old and dirty) with the latest sprintgas kit w/ mixer ring in the elbow connecting to the throttlebody. Had the super high lift, high duration wade cam profile 1532(?)

Yes, it looks like a huge restriction, but i did have my boost gauge fitted from my previous supercharger kit. At 3000rpm, i was a needle-width away from 0 (natural atmospheric pressure), which hardly dropped all the way to redline.

Which is alot of air, honestly, ignore the fact its there, if its the same ring design as mine, the design seems quite efficient.

/Remember: A dirty filter does not cause a restriction! http://www.autospeed.com

Anybody want to sit down with a slide rule and or calculator? If you are operating at 3/4 (approximate) or less throttle, the throttle butterfly causes as much restriction (or more. Mixer has constant opening) as the sprint gas mixer ring fitted to the 4l motors. I don't know anybody who works their motor at full throttle for any real length of time. Very short engine lifespan if they do.

anyone delt with forced induction through a vapour draw system?

No but i have researched into it, give GRA (Dandenong, vic i believe), they can help you out.

Different systems and converters can flow enough lpg for 160-180-200rwkw's.

A b2 converter will do the trick, secondhand on ebay they are cheap, what you do i read a while ago is fit a 5/8th copper line from the breather diaphram on the converter to the vac/boost line, so under boost it feeds in more lpg.

No tune required apparently

Champion!
might have to look into this, love gas turbo's and wont be running to much boost, plus my project car is already on LPG so i wont have to f**k around to much with it.

I have had a few years of driving on a ring mixer turbo, just hit 222.5rwkw.
