The Gas XRSC Series is ATM Innovation’s most affordable "street/strip" race carb yet. It has all the features of high-end race carburetors – based on quality ATM™ die cast aluminum main bodies, metering blocks and throttle-bodies. This cost savings over billet components doesn’t hamper performance, and you still get ATM's™ all aluminum dual inlet, dual site-window fuel bowls, changeable idle and high-speed air bleeds and changeable idle feed and power valve channel restrictions providing endless tuning capabilities. The throttle-bodies have vacuum tubes for vacuum advance and PVC hookups. These carburetors are precisely calibrated at the factory and are “race-ready” out of the box requiring minor “trim” adjustments for atmospheric conditions and your individual race combination. They are available in 650, 750, 850, 950 and 1050 CFM sizes for 4150-style flange manifolds.

  • 4 Vacuum tubes in throttle body, (2 are 3/8" full vacuum, 2 are 1/4", 1 full, 1 timed)

The best

XRSC Street Strip Series Gas Carburetor

Pros: Ordered a carburetor built to my specs. Bolted it on out of the box and didn’t even touch idle screw. Carb runs perfect from off idle to wide open. I will never buy another carburetor that isn’t a ATM!

Cons: No cons, ATM is the best in the business.

The best.

XRSC Street Strip Series Gas Carburetor

Pros: This carb is dead on perfect out of the box. Didn’t even touch the idle screw. Throttle response and drivability is like no other carburetor that I have used. For future carburetor needs, I would never even consider looking at any other brand.

Cons: No cons, these guys know what they are doing.

Awesome

XRSC Street Strip Series Gas Carburetor

Pros: Sent my build sheet and ordered 750 XRSC. Got a call from ATM recommending a 850 XRSC B based on build sheet. I guess I confused them, cause I listed to configurations I could run. After clearing up the configuration I am currently running they went with my original 750. Received carburator and installed right out of the box. Worked great, runs strong all gears. The only adjustment I had to make was set idle. Excellent customer service!

Cons: None

XRSC-950

XRSC Street Strip Series Gas Carburetor

Pros: Bought this and never looked back. Instantly gained 2.5tenths and 4mph over my 4779-6, only setting the idle. This one was off the shelf. I wonder how much I really could have gained if I told them what I really needed and they built it for my car.

Cons: NONE
