Carter Thermoquads ~ 'More General Information'
4bbl.
I have two 850 CS TQs, bought one new in the 1970s, push in jets. Mate recently bought an 850 & 1000.
The C&S aerosol carbs have been around for years, probably 20 or more. I used to see them advertised in CT magazine. The theory looks good, but if they really
work well, why are not more in use? Especially Nascar type racing.
Bewy, the 72-up TQ carbs use the Aerosol design on the secondaries until 1984. if you're using that carb, you're already using that design. millions of Chrysler cars used it during that time period, and any surviving running 4 bbl. cars from that era, are still using it, on the secondaries.
if you already have 2 CS type carbs, why are you asking me where the air bleed circuits are ? take one apart, and trace them out, and pin them out.
if you're going to run a CS, may as well run the 1000. go for the gusto. lol. lately, it's not like these cars get driven much anyway, with $6/gallon premium. gas price shocks take all the hot rods off the streets, I've seen it before in 1970's. they collect dust in the garage, and it drives the price of average V8 cars down as well. my kid has a nice 95 Bronco w/302. 32 gallon tank. even if he gets the "cheap" regular 87 octane, it's $160 to fill it up. driven daily, that's $650/month. the party is over. that's a payment on a brand new car or truck, with full coverage insurance. the mortgage on my house was less than that in 1994. the gas is worth more than the vehicles now. the fun is over.
NASCAR doesn't use carburetors anymore, period. they're all fuel injection. NASCAR stuff doesn't belong on a street car anyway, most of that high end pro racing equipment on a street car either doesn't work, is total overkill, or a major pita to use. it was a wide open all day carb pegged to the boards, on the superspeedways, when they did use carbs. on our streets we're limited to 65-75mph highway, and only 35-55mph on secondary roads. with cops and speed traps everywhere. what's the need for anything that NASCAR would use ? there's nowhere to open it up without getting fined, arrested, or worse. they'd have poor part throttle drive-ability, and terrible mileage. if you drive consistently 80mph here you're gonna get so many fines, you'll point out on your license, and it'll be suspended. if you drive 100mph or over, when you get pulled over, the police will be approaching your car with guns drawn, you'll be on the ground, getting handcuffed. driving over 85mph in some states is a felony, with mandatory court appearance, and a $300/hour attorney. 100mph in my state, is automatic suspension of license.
a spreadbore Qjet, TQ, Holley, etc. is really all you need, for the street. or a 750-850 square bore Holley if you want to step it up a bit. even an 850 Holley is too much carb for most street cars on pump gas, it's too rich, and loss of idle signal due to the large 1-9/16" primaries.
if you're getting 10mpg now with a big block/Holley 850, you need to be retired, and a wealthy millionaire to enjoy it, on a daily basis today.
