Ever take one apart to see if those boosters could be repro'd and fit into a std TQ?

I imagine some of the tricks that went into the Comp Series design could be incorporated into the std TQ's, No?






I've taken many of them appart but haven't gone into any frankenstein experiments with the boosters, mainly because I haven't really found the need to. I suppose anything is possible if you played with them enough.


not sure what boosters are being talked about but i have read where you can cut out the outer ring of the booster on the 850 TQ making it about 1000 cfm's, and if you remove the choke plate and related shafts add another 60cfm's. BTW these TQ's are also popular with the big cube Buick guys.




To make an 850 Comp series into 1000cfm, cut outer ring?


any 850 TQ, but will need to be jetted up i suspect

Jetting of any carb will depend on the engine combo underneath it as well as other factor like altitude etc.

here is what i have noticed about this debate: 1) guys who hate thermoquads will never use them
2) demonsizzler is mentioned with glowing reviews in regards to thermoquads
3) demonsizzler does not chime in nor toot his own horn (I have no idea if the 'sizz toots anything else )
4) I have run out of things to say.
5) demonsizzler; expect a pm from my dad. We need a thermoquad set up, the right way!

Threads like these draw amazing attention. You get all different takes of course, but I can't help to wonder how many people who talk against the TQ's have ever even used one, let alone taken any time to learn and tune one??? Even just basic tuning




Yup, I was told when working on my TQ to chunk it in the trash can and buy a Holley. I asked why, have you ever run a TQ, the answer was no. The only real world experience this person had was what other people had told him. I run the 850 on my teen and it runs flawlessly. Would I ever run a Holley, maybe, but I got 60 bucks in my carb, when I can buy a quality piece for 60 bucks I might just try it.

As far as mileage comparing 2 318s one with Holley and numerically lower gears gets about the same as mine with numerically higher gears and a TQ, in fact mine might do just a tad better. Same body car.

IIRC HotrodDave had a 850 TQ on his super MPG 318.

Your right Walt

I also had a 770 street avenger for a while and it ran just as good but never got near as good of MPG.

But the TQ is a piece of junk! Over carbed 318!

How could that be possible?

Sure, why not? May not have "razor-sharp" performance, but it leaves room for "growth"!!
It's mostly about the NEEDED amount of airflow, NOT the TOTAL rating of the carb, Doc. Jetting, float height, choke unloader settings, acc pump settings do have an effect on performance (model depending)..BUT.. you CAN fit the TQ on a 318 and have decent performance!! Personally, a 360 TQ model would be about right for the '18.

I'm like everyone else... have a big steaming pile of tq's which I can't bring myself to throw in the trash.
BUT.. this thread does get a guy thinking....
I believe the main reason the tq didn't get the popularity is because they are a pain in the junk to open up and tune or fix problems. Way to much finicky linkage and screws and garbage.
If you wanted to start from scratch, its a labour of love. By the time your done , if you sell it you might recoup your money you have into the carb kit.

It is a good design, but could have used a couple more mill into engineering.

back-at-you. Pick up a TQ manual, for once, and find out why!! For "junk" to perform well on a 318, is NOT that it's a possibility, it's an EVERYDAY occurance!!

Good point!! When do you want to "rid" yourself of that pile of TQ's? Seriously,
there are combos built with the TQ (or TQ's - yes Scotty, I need more power! ) that run very strong. BTW they are NO HARDER to work on than a Holley.

HYPER - ...

WE are talking about a low-rpm MPG application ... NONE of what-choo mentioned above really has anything to do with that.

The primary vent SIZE is what matters ... and a 1 3/8 (I would think) would work the bestest there.

I have a 1 3/8 on my Discoverer motorhome(413 power) ...and it has performed GREAT. NO NEED to get into the secondaries uNder normal flat-road cruising operations at around 60 mph.

Good for you, that you have chosen that size of primaries for YERR 413 'DISCO!! But Doc... contrary to the nonsence that's rattling in yerr
head, I made that point of primary sizes a-WHILE BACK!! Lay off the pipe!!

Yes I saw it RT .. but it never registered that it was a 850. HONESTLY ...I think that some more MPG could be gotten with the 800 carb ... and MAYBE some-more with a reduction of the vent size ON TOP....or on the bottom.

Now to HYPER - ...will he EVER get his ride fixed ? ... ME THIMKS not ! ..

Your problem is that you put a lot of time and effort into being an IRRITANT, instead of working YERR OWN PROJECTS!!

You must have 1 of these? Known as "Super Quads", these are not Competition series carbs but rather an over the counter "One size fits all" replacement. Good carbs but not considered to be anything like the Competition Series units.




Looks like it.

I love the TQ's, going to run one on the GTX again when it comes out to play. The more I tinkered with it the faster the car would go!
