Worth A Whistle: Katech Compression Ratio Meter

The WHISTLER from Katech Inc. is an electronic device that instantly determines the compression ratio of virtually any engine to within a tenth of a point.

"The WHISTLER is easy to use," said Caleb Newman, director of aftermarket operations, Katech Performance.  "Just remove a spark plug and screw the WHISTLER adapter in its place.  Then enter the number of cylinders, CID and temperature of the engine.  Finally, bring the engine to TDC (top dead center) and the unit will display the compression ratio."

Also required to use the WHISTLER is a low volume air source and 120Volt AC supply.

"Sanctioning bodies use the WHISTLER to enforce compression ratio rules without tearing the engine down," Newman added.  "It's a great tool for the most serious engine shops and racers."

The WHISTLER works with four-, six- and eight-cylinder engines ranging from six to 600 cubic inches with a temperature range of 30° to 200°F.

Included with the unit are:
*  FN, BN, BL, J and 18mm spark plug adapters (12mm motorcycle available)
*  Verification bottle (to check the calibration of the unit at any time)
*  Easy-to-understand instruction sheet

The WHISTLER sells for $2,095 and can be purchased by calling Katech Inc. at 866-KATECH1.
