Used for engine build after cracking ringlands. Broke in and is fairly quiet, no piston slap (yet, will see during winter). Holding 390whp on a dom 1.5 no problem

QUESTIONS & ANSWERS

  • Q: Block  22_STI_Tbriggs1 month ago

    (2018 STI) If i got these pistons and also got Manley Rods, i would i need to upgrade the stock block too? or would it hold up?(Im trying not to blow up my engine in the future)
    • 1 of 1 people found the following answer helpful

      A:  The only required modification you would need to do to your block in order to run these pistons would be to bore out the cylinders to the correct size for these pistons.

  • Q: Compression Ratio   Sasuke11 9 months ago

    Seeing the stock compression is 8.2:1 what’s the difference the motor will see at 8.5:1? Will the stock tune be sufficient for a break in? Will I see some turbo lag or quicker spools? Or is a pro tune right off the back a necessary?
    • 1 of 1 people found the following answer helpful

      A:  You'll want to get a break in tune done by a pro-tuner. Higher compression typically helps spool up a little bit, but compression ratios can vary slightly with different head gasket thicknesses and head chamber volumes.

  • Q: Manufacturing Material  Plazma10 months ago

    Specifically what type material are these pistons manufactured from?
  • Q: anti friction coating  mukrat11 months ago

    is the anti friction coating that says comes on these piston "ceramic coating"?
    • 0 of 0 people found the following answer helpful

      A:  "No, the ceramic coating is used on the deck of pistons as a thermal barrier. These pistons come with a moly based skirt coating promoting lubricity reducing friction between the piston and the cylinder wall." -Manley Rep
