Gene Berg grooved venturi for 48 DRLA Price: $40ea
|
In our experience, the biggest bang for your buck you will get.
With a regular venturi, you are dealing with a set number. Increasing the size will give you more volume at the expense of airspeed. On the flow bench, both airspeed and volume showed an increase with these venturi. If you are running a 34mm venturi you can opt for the 32/36, which will give you better top and bottom end, or the 30/34 which will keep the top end where it is but give you a lot more bottom end and drivability. At the end of the day, the limiting factors will be the cam and heads. Be aware that you may have to increase the size of the air or drop the main jet size to accommodate the extra flow. We recommend having an 02 sensor for proper jetting & tuning.
The original and best. Originated at Gene Berg Enterprises by Doug Berg in 2013. Pat. Pending.
