Anybody had problems with p & g check

new design starters and 16 volt batteries will crank them fast, and big!!!

I wouldn't doubt that there could be variations between the P&G meters but my engine has always been dead on down to a fraction of an cubic inch when checked. That includes testing with both 12 volt and 16t volt starters.

Its important that the test is corrected for engine temperature.

Like Lynn said if cranks too fast will pump big,had pulling customer pumped 481 with a 468
he had old delco hi torque with big dozer battery,they then pulled head and measured bore and stroke and could'nt measure stroke correctly they measured 4 1/4 so customer wanted to know if we could have ground crank wrong, no can't grind crank .010 and add 1/4 stroke,LOL ,we tested later would pump 481 could put in gear and let clutch out enough to slow cranking speed down would pump 468 then, when cranks too fast first hit of compression it blows the piston up farther than should.

My odd fire V-6 always checked big, until I started pulling all plugs and rockers and slowing it down with a 12 V-batt. Then it pumped right on. Part of my problem is I use a 142 tooth flywheel. like others have said. Temp and starter speed. The first "Hit of the puck" will usually set the ring.

PMS in San Antonio (Adrian Pendergrass) is the only one making them for the last 15 years or so, he builds them, sells them to everybody else (Power House, Comp Cams etc) and supplies all the Sanctioning bodies from NHRA, LSR, World of Outlaws, Nascar etc.

He'd be the one to answer your questions. 210-681-2405

Question???-- are you taking ALL the spark plugs out of the engine and removing the push rods from the cylinder being tested????--we have used 12V/16V/24V starters to makes no difference- we get pumped regularly and never have had any problems as long as you correct for engine temp---- if there ever is a problem with one cylinder which RARELY EVER happens we move along to another cylinder still pumps accurately tho---we know exactly how big our engine is no guesses there--- never had to pull a head in the last 30 years--FED387
