What do you guys think?

[mulot30th]

If I take compression on a stock apex engine I get around 200psi on my gauge.


Then I take my turbo apex compression I get around 150psi and that is on 10-1 Je pistons and stock head gasket. Engine runs good and all cylinders are almost equal within a few psi.


I just wanna know if that is what I should expect (150 psi vs 200psi).

thank you guys!

That is about right, but also keep in mind cam timing, throttle open or closed affects PSI.

Cam timing is stock.

I tried open throttle or closed... get the same reading.
