Thread: thermoquad carb

does any one know the cfm of a thermoquad? And is there any objections to this carb as a performance carb? besides being ugly. I ran one on my bb chevy before and was inpressed with the performance but this was for short period for what ever reason,and I was wondering if any one out there is running one?

There are two sizes, I think they're 850 and 1000 cfm. I run them on Mopars, Chevys and Fords have too much fuel pressure. (Too cheap to buy a regulator!)

I always liked them. I was working in a Chrysler/Plymouth Dealership when they first came out and went to the factory course on them.

I still have a couple builder laying around. Biggest problem I had with them was when people tried to rebuild/adjust them themselves who didn't know what they were doing.

One minor problem that occasionally pops up with them is that the plastic center body can warp a little bit. Any time I rebuild one I take a sheet of glass and lay a sheet of 400 wet/dry paper on it. I then place the the center section on it and move it in a figure 8 pattern until the gaskget is flat again. Other than that just make sure you put all the parts back in, especially the 2 flat O rings in the fuel wells.

They're ok until you catch it on fire. ever saw one that had melted? it ant pretty.

but thats the only one ive seen melt down. if you think the carb. looked bad you should have seen the rest of the car.
