XFChris 126 Posted October 13, 2014 Chanced upon this LPG mixer ring at the wreckers. Has some sort of lid on it, as shown in the above picture, I'm not sure what it does, looks like it blocks all airflow in? With the lid off, the carby barrels are just about exposed, most LPG ring mixers I've seen partially block the barrels. I think this would minimise power losses when running on petrol, compared to a mixer ring with a smaller inner diameter, bit I have no idea if it will be good for LPG. I have heard that LPG needs restriction to work well. Share this post Link to post Share on other sites
deankxf 20,286 Posted October 13, 2014 My XE ghia had one of those when i got it, seemed to work ok.. looks heaps restrictive.though. the ugly Impco 300a setup was the best i had on a 6cyl. far more reliable when new too. 1 matt_lamb_160 reacted to this Share this post Link to post Share on other sites
adrianphu123 73 Posted October 13, 2014 I've had more success with a 200 mixer and the EFI manifold but my biggest improvement by far has been getting a new converter. My old one sat vertical and had oil and gunk about an inch high from the bottom since it hadnt been touched in about 10 years. Share this post Link to post Share on other sites
Gaz 1,085 Posted October 13, 2014 200 is a waste It's only benefit IMO is the ease of mounting on a crossy. You would be far better off with a B2, same design but less restrictive without the right-angle air path. 300a's have a cable operated lid that you can open up to run on petrol to decrease the restriction but they won't run on gas with it open. I never open mine, it fucks with the mixtures too much. Share this post Link to post Share on other sites
adrianphu123 73 Posted October 13, 2014 I think you mean 225 gaz, not B2, but i tend to agree. When i got mine tuned, we richened up the mixtures quite a bit so the 200 might be a bit too small Share this post Link to post Share on other sites
Gaz 1,085 Posted October 13, 2014 Yeah your spot on I don't even know why I wrote that. Share this post Link to post Share on other sites
