forged engine compression
I did a compression test on my car last night while changing plugs and fitting new coil packs and got 9.5bar from the front two cylinders and 9bar from the rears.
Is this ok? Engine is cosworth forged pistons and rods ej207 nitrided crank Cosworth head gaskets Jdm sti avcs heads (standard) built compression was 8.4:1 Engine has covered 2500miles from rebuild |
130-137 psi...pretty even, I think a standard block is around 150psi but dont quote me on it ;)
