Q 320 Grates

[Joe Anshien]

There really is nothing you can do. It's a combination of low hood height, and small space per BTU. They are what they are. They're not meant for much more than simple "grilling". Dogs, burgers, what have you. Without jumping through all kind of hoops you're not going to do the type of cooking someone with a Genesis or larger grill can do.
The cast iron is NOT responsible for the high heat. If anything it's what tames and evens out the heat. These grills need that large heavy mass to cook properly. That's why regular grates are useless in them. So you need something more like these types to truly get somewhat close to mimicking the OEM grate and it's performance

If your grill gets too hot or not hot enough you can get an adjustable regulator. I got one like this for a boat I had that was originally set up for butane and didn't want to mess with trying to find new orifices for the oven and stove. Worked great. https://www.amazon.com/dp/B07GRFTR4S/?tag=tvwb-20

All I can say is that I hope no one uses a system like that unless they are very careful and know what they are doing.

Of course when anyone is using combustion they should be careful. Adjustable regulators are quite safe and allow you to fine tune your grill. Easily get it a little hotter or run it cooler. I had a little Coleman cast aluminum infrared travel grill (before I became an adoring fan of Weber Qs) on the boat that ran at 500 degrees no mater what I set it to. I hooked up one of these and was able to cool it off to cook fish and chicken.

I have one of these and I use it with my DIY Frosty T-burner forge for heat treating...works great! I can get a raging flame out of it. I can get a fair-sized chunk of steel to glowing-red heat-treating temperature (1500F) quickly.

And that's where it becomes problematic, using this in an application that calls for a fraction of a PSI. So for those intrepid souls that travel down this road, forewarned is forearmed...if you use something like this to extend the adjustable range of your grill, there is a very real likelihood of exceeding the safe limits, low or high, of your grill. It would be nice if this had adjustable stops, but it doesn't, so proceed with caution.

Definitely can easily put you in the Darwin awards club. Those regulators are NOT meant for grills and other low pressure applications. They are meant for large scale LP burners i.e. turkey fryer, construction heaters, etc. They also at lower pressures are not stable and can creep up or down leading to total flame out (leaking gas) or extreme (for a low pressure appliance like a grill) flare ups
