The Hole Story
News from the honing industry leader

Ladies and gentlemen, hone your engines!

Sunnen Honing Systems used by championship race teams demonstrated at PRI 2014.

PRI 2014 -- the largest gathering of motorsports professionals in the world -- is set for December 11-13 in Indianapolis. Sunnen's Automotive Team will be on hand at booth #5101 to demonstrate performance-enhancing honing systems used by racing champions throughout the world.

In fact, the race teams of Kevin Harvick, the 2014 NASCAR Sprint Cup Champion, Chase Elliott, the 2014 NASCAR Nationwide Series Champion, and 2014 NHRA Pro Stock World Champion Erica Enders-Stevens (the first female Pro Stock Champion), all use Sunnen cylinder hones in their garages. Sunnen truly is "the hone of champions."

Come see why at PRI, booth #5101.

Sunnen SV-20 Honing System

Sunnen's two most popular honing systems for engine builders, the SV-20 and SV-10, will be demonstrated at PRI 2014.


The SV-20 honing system, developed specifically for race shops, production rebuilders and fleet maintenance facilities, combines Sunnen's linear servo-stroking technology with the power and capacity to drive multi-stone diamond tools for OEM-quality bore geometry on automotive blocks and cylinder liners. Click here for a video preview of the SV-20.

Sunnen's SV-10 Automatic Cylinder Hone combines the latest technology with the consistency and dependability of the legendary CV-616.

With two motors, one for the spindle and one for the stroker, the SV-10 runs standard Sunnen tools as well as Sunnen's DH-series diamond hone head.
