    compresssion results

    Did a compression test on my evo 9 with 107,000 on it on e85. Going from driver to passenger the numbers go as follows 140,140.130.149, are these results ok for a 9 I read that it should be around 160 but also that the 9 read lower some help is much appreciated thanks

    Those sound like great numbers provided there is no oil in the cylinders that is aiding in sealing of the piston rings. I would follow up with a leak down test to see how well the head is holding up.

    As long as your within 10% of each other, those are good numbers.
