Bestselling 34mm+ Custom Machined Venturis For 44mm Kadron Solex H40/44eis Perfect Gift [fanzDduU]

Do you need serious power for your larger displacement?  Venturis are available to match each and every engine combo.  Whether you are running a stock 1300 or a wild 2 liter, these venturis are the best bet to get the most power out of your engine.  They come in two distinct styles.  The 28mm, 30mm, and 32mm are genuine Solex parts.  The 34mm and larger ones are machined from genuine Solex cores with the proper taper and matched to the 44mm sized throttle bodies.  With the machined ones, there may be some pitting inside due to porosity of the metal when molded.  This is perfectly normal and will not affect the operation.

Here are some recommendations:

1300cc's to 1641cc's: Use 28mm venturis

1679cc's to 1955c's: Use 30-32mm venturis

2 Liter and up: Use 32mm-35.5mm venturis

For higher RPM engines, 44mm throttle bodies coupled with 34mm machined venturis work exceptionally well.  We can machine them out even larger for racing applications. They can be used for smaller displacement engines than listed above if your intake manifolds, cylinder heads, and exhaust system is set up for higher performance operation.  The correct 1914cc and larger engine can really benefit from this set up.

Note:  You WILL need to change your jets when using larger venturis. We can also supply jets to match every combo.

Note that these custom-sized venturis are machined by hand in-house on a case-by-case basis.  Lead times can vary.
