intake tract

Recommended Posts

I have been working on a new intake system based on the 09 intake boot and using a clamp on filter i have made the carburetors with a new type velocity stack that acepts the 09 boot .The new system picked up 11 cfm @ 28"h2o over the stock 09 450 system with the TB in place so i tryed the moded carb and it actualy flowed 3 cfm more than the 50 mm throttle body quite a suprize .I have played in the past with butterfly carbs and a slide carb all ways out flows the butterfly it would be interesting to take somthing like an lectron 50 mm carb and use it for a TB .
