Why do Cylinder Sleeves Drop? | Darton Sleeves

Modern engine builds are now producing more and more power than ever intended often at 100+ Psi boost pressures that were unbelievable not all that long ago, especially on small 4 cylinder applications but due to products like Darton Sleeves, the unbelievable is now a reality. John Catapang from Darton Sleeves answers some of our questions on why OEM sleeves are so limiting and how these issues have been addressed with products like their ductile iron MID™ sleeves.

John and Andre discuss sleeve installation requirements, open deck limitation, OEM sleeve issues (thickness, material quality and ductility) and how quality aftermarket sleeves can avert these problems while at the same time increasing the displacement potential and handling much greater amounts of heat, pressure and movement.
