New Q Jet

Lyn Smith · 12-16-2022, 09:25 PM

Just spotted this new aftermarket Qjet carb being sold on the internet( Amazon ,Ebay etc). Wondered if anyone else has checked it out, and if it is legal for NHRA? I guess if it measures ok for the application. Funny how the ad says it could " flow 750 - 800" . They are being sold under 2 different brand names. Thundermingo, and lvantelope. One ad gives this description of a carb."A carburetor is a rigid mechanical device, which acts as a core function for the motor".Good to know. LOL The ad also says " If you have trouble getting the engine to idle correctly after you install the device, please feel free to call them".Make sure you take a note of the time change in China before doing so though.LOL One site has sold a couple hundred of them, but the reviews are not good.

They are lighter, as they are all Aluminum. Have not measured one as to Venturi and throttle blade dimensions for being legal for 750 Q Jet replacement. If they measure correctly, I assume they would be considered a legal replace carburator for Stock or Super Stock? Maybe need to get an official response from NHRA.

Just bought a new 800 cfm for 89.00 on a auction site. I have not looked yet with measurements, but I will

Jeff would you let us know if the carb is marked with any GM markings or "Rochester" markings? Merry Christmas Ray

I saw one, held it in my hands, they are as light as a feather. I don't recall seeing any copied logos on it. Guy put it on an old truck, it ran.

They are junk don’t waste your time. I looked into building one

Are they made in China?

China knockoffs just like all the other stuff they are copying
I saw it last week myself and thought they will copy anything

At least someone tried
It’s all about the casting
Need Deano or Danny Ashley to check one out

I have a original Weber 38/38 on a six cylinder, I bought a Chinese replacement on ebay for less that $90.I have never used it but it's incredible how identical it is, any parts I've tried can swap back and forth. It's crazy how light it is though I literally thought I was recieving a empty box !
