Felpro HG 26171PT how thick when compressed?

Post by scoobydo » Wed Jul 17, 2019 2:14 pm

Guys I am in the UK and parts hard to get. My cylinder number is passing combustion gasses to the coolant. Have took head off and it needs a light skin and would say chuck the cometic in the bin. Cometic measure 1.3mm. At this moment not sure on how much of a skim is required but have concerns about how thick the felpro is when torqued down? Apparently the pistons are Custom JE low compression Pistons 7.6:1

Thanks

Anyone able to confirm if I have the correct felpro part number and also is possible the crush thickness so I can work out my CR

Worked out the CR and it is 7.13 if I use the shim that I purchased to bring everything back to where it was prior to the skim. Previous owner put 7.5:1 JE pistons in it as suffered from DET (dont ask). Seems very low but car makes good power low down maybe a bit laggy.
