Engine Compression Ratio Verification with Katech WHISTLER™

Verifying compression ratio is an important part of engine inspection, particularly in competition classes with compression ratio limits. The Katech WHISTLER™ provides a method for checking engine compression ratio through a spark plug opening without removing the cylinder head.

Proper setup, accurate engine displacement information and the correct spark plug adapter are essential for reliable measurements. Refer to the product page and operating instructions for testing procedures, equipment requirements and measurement conditions.
