M.R.E. also offers HVH Super Sucker carburetor spacers. They are available in 1", and 2", in aluminum and plastic and for many different applications. These spacers have improved e/t and mph time and time again. We have seen atleast a tenth and half in e/t and 2 mph just bolting it on at the track. Since these spacers greatly aid in throttle response, torque, and booster signal, we have tuned atleast 10-15+hp on the dyno. We have seen these spacers improve signal at the boosters so much that you may need to down jet and/ or increase air bleeds for best results.
