hey patrick just put a sv1 on my 632 having some issues with it. its hard to do a burn out with it , when you come down on the trans brake it almost feels like it almost floods the engine . very rich at a idle. but when you clean it out it sounds bad ass. the fuel levels are set at 25% 2 turns out on air mixture. its kills a set of plugs pretty quiwk. thanks for any help

The SV1 is infinitely tuneable at idle, light and heavy throttle as well as wide open.

This allows you to tune it to be crisp and clean in any rpm range.

SV1 (PRIMARY SIDE) Body Photo:

Location of various ports on SV1 (these are on both the left and right sides on the FRONT ONLY). The single blade acts like a giant dispersion tool to atomize the idle and cruise fuel.

# 1 is the Intermediate tube (if equipped). The smaller these are the LESS fuel will be supplied 2500-4000 rpm.

But unlike a Dominator carb increasing or decreasing this port feed or any of these port feeds will not change the overall air to fuel ratio at wide open throttle.


# 2 is the Transfer port. The smaller these are the LESS fuel will come out in the 1000 to 2500 rpm range.

# 3 is the Idle port The smaller these are the leaner it will be at idle, but the richer it can be at light throttle.

# 4 is the Transfer port. The larger they are the LEANER it will be at idle to 2000 rpm BUT the richer it will be from 2000 to 4000 rpm

Vice versa applies to the above information.

You don't need to adjust any of these if you wish. We can baseline them quite close on many combinations. You can then simply do normal changes to air bleeds up on the top of the carburetor to effect operation.
For example: The larger the idle airs, the leaner it will be at idle and cruise.

But air bleeds changes are a coarse adjustment in comparison to the tuning abilities of these circuits.

These 1,2,3 and 4 circuits are simply additional circuits that allow you (if you wish) to fine tune the design to a very fine level of tune that will rival and even surpass fuel injection in idle, throttle response and driveability operation. As this design can better atomize the fuel than an injector can due to the air speed impacting the ports at high and sometimes sonic velocities at cruise.

Also note the boosters simply draw out forward from the front (we have pulled one forward to demonstrate...you can do this by hand no tools required..spray it with some WD-40 or similar for lubricant and pull it through). This is in case you wish to change boosters and vary the cfm of the carb or change the atomization properties.

Note the check ball that orients the booster, this ball is trapped in the body when the booster is installed. Early models used a locating pin.

The boosters float on o-rings mounted in the body. This is to dampen harmonics/vibrations and ensure consistent fuel flow under load.

Hope this helps you better understand the design and its features.

We've been showing engines...but this is some great car porn. A very cool 1969 Mach1 Mustang (we hope you agree), we thought we would share as these cars are getting so rare.

Mike Doughrity's 466 c.i. makes 625 h.p. He went from a competitors E85 carb to our E85 SV1 and picked up almost 2 tenths and 3 mph.

What is the best dual throttle return spring bracket kit/system to use with the Pro Systems SV1? I am using a Lokar throttle cable on a BBC/SuperVictor 4500 combo.

The SV1 uses throttle brackets: Jegs-15237 for 4500 bolt pattern and Summit G1419 For 4150 bolt pattern

Currently available nitrous plates for the SV1 that do not require a spacer under the SV1 for blade clearance are:


1. HALO for the SV1 (# 22750 for 95mm blade and 22760 for 110mm blade)
2. NX Gemini Twin (Use the 4150 for the 95mm blade and the 4500 fits all sizes)
3. ZEX Perimeter (use 4150 for 95mm blade and 4500 fits all sizes).


The SV1 uses a Dominator base air cleaner like the Moroso Part # 65920.


The SV1 uses CMW 8900 (Callis Machine Works) or Biondo PCTS inline throttle stop (specify big bore cylinder).

Best Machine Racing Engines just built a beast. Its a 571 c.i. 12 degree Raptor engine for the Milan All Motor class. It uses one of our big single SV1's on Q16 fuel. The fuel curve doesn't get any nicer than that. Great power...nice work. Engine builders amaze me these days.

i havent got to test it yet it was pretty rich at a idle after playing with the air bleeds cleaned it up now it sound nasty. i hope it runs as good as it sounds.

Very curious about this carb. I have a 376 L92 headed LS engine with a 1000 cfm Holley HP. What you thinking the SV1 will pick me up?
