The SV1 carburetors are now available for all the big 850 plus cubic inch engines.

Bischoff Engine Service used a pair on their XTF/Pro Street 856 Nitrous Hemi to make 1800 naturally aspirated horsepower.  

To Quote Tony Bischoff "The fuel curve was perfect top to bottom, you could tune any cylinder to any air to fuel ratio you like AND they roll into the throttle so well it felt unnatural."

Pro Systems expects the SV1's to replace the use of Split Dominators on all these big engines as the SV1's offer better cylinder to cylinder control, better atomization of fuel and by combining engine pulses, cylinder fill is improved as well.

Plus for less than half the price of a set of split Dominators the SV1's not only save you money, they save you weight as they are lighter. (16.4 lbs total for BOTH carbs!!) AND the SV1's do not require complex throttle linkage so throttle operation is very smooth.
